"The past is a foreign country"

Most journeys have the purpose of exploring something new. Not so my travels during the last few weeks, which brought me to the parts of the Europe in which I spent my earliest works aboard and learned my first foreign languages, namely English and French - as German is my mother tongue. I was surprised that my French still worked reasonably well after so many years. But more so, I was surprised that more and more French speak English now. 

Though the purpose of this journey was not just personal nostalgia, but also to get an impression of Universities, Colleges and Schools on the way. Specially in England the route went along such sites like London, Oxford, Bath, Bristol, Manchester and Cambridge. I was surprised about Bath, which has developed into quite a campus. But it had the handicap of a place which markets itself with student's satisfaction instead of academic merit - an understandable positioning in the "education business", but not hugely inspiring. All other places, and the small ones in between, were of nice character and some spirit living in the walls. I enjoyed a lot my visit of the Royal Geographical Society in Kensington Grove, which I am a fellow of, and seeing the places where the famous explorers of the world reported about their journeys. I will for sure spend some more time in London and make use of the Society's library for a month or two. In Oxford I was also reminded of my time lecturing there in the School of Geography in the mid 90s. It was one of the last things I did in that field, and it felt like the best place for a farewell to science. The German University and education system back then felt like a waste of time and I did not pursue an academic career, but went out and looked for a "proper job". Ultimately, a lot of this ended up being a waste of time too, but a lucrative one, which still opened me a lot of opportunities. By now, I understood, that "career" is just a way to integrate into society and explain to HR departments and the tax office that what you are doing actually makes sense. 

A nice little stop at a nearly unknown academic location was the one at Keele University in Staffordshire. It is a small University campus, just a bit North of Shakespeare's city Stratford-on-Avon and Birmingham, up the hill of Silverdale in the suburb of Newcastle-under-Lyme. This was the place where I gave my first academic talk at the School of Earth Sciences, while I was working at Wardell-Armstrong in Newcastle. I always liked the messy old office in one of the corners of Keel Hall, which is overlooking the park. No idea whose it is, and what is done there. But back then I though, if somebody gives me an office like this one day and a lot of time, I will be happy. 

Of course, I also dropped by the place where I lived at that time, which was not in Newcastle, but over the hill and just over the border to the neighboring city called Stoke-on-Trent, in Victoria Street. I am not sure whether my former landlady, Frances Griffith, still lives there. It is about 20 years ago. I have been still writing to her a few years after. But finally letters stayed unanswered. Lucy, the old lady living next door must have passed away. Her place looks abandoned. Frances and Lucy always shared their flower seeds and were growing them in their gardens towards the back alley. It was a recession in England. And then there was Pauline, the hippie, which lived next door of Lucy. I think she went to Australia. 

Stoke-on-Trent is a conglomerate of smaller places which once were the heart of the English pottery industry. It is the place of "Bone China" called the Potteries. Most of the old bottle kilns have been converted into museums. What also reminds of that time, are the canals which were a means of transportation for fragile goods and span over large parts of England. Today they are still operational and you can use them with longboats, also called arrow boats, for recreational purposes. From the marinas you see England not from the road side, which is always the more interesting perspective.  

A few miles North-East of the Potteries is the Peak District, and the landscape changes dramatically with steep rocks and moorlands. I often went there on the weekend to go hiking or caving in the karst caves. The caves inspired me in 1990 to try and model the development of them using a Monte-Carlo approach simulating the dissolving processes of the limestone. I discussed later with Tim Burt in Oxford on it. My simulated caves looked really beautiful, but the structures I calculated had nothing to do with reality. My idea to use the model and identify the age of the caves did not work out at all. In the end I scrapped the plan and changed my master thesis topic with Helga Besler at Cologne University to mathematical modeling of particle dispersion, which was related to my work and much easier. In the Peak District, just beside the National Park, is a nice little town called Buxton. It has some springs, and people came here for them in the past. There is still a pretty little opera house and a green house. It is a good base to explore the karst and the moorlands around. 

Stopping over in Manchester re-confirmed that most cities which are proud of their soccer club, have not much more to offer (Madrid and Sao Paulo are obvious exceptions).  

In Cambridge I met a friend and former colleague from Wardell Armstrong. It has been about 20 years and was nice to "catch up" in the way, as if the 20 years actually did not happen. We enjoyed it a lot over dinner in Midsummer House. I rarely mention restaurants, but this one is quite special and should not be missed when staying in town. The University of Cambridge is similar and different to Oxford. I never did anything academically in Cambridge, so I do not really have an insight. But from my impression Cambridge is more lively and connected than Oxford, without compromising on heritage and ability to focus. But this is really just an impression gathered in a few hours. 

Arriving Dover via Canterbury I had a surprise: there are no ferries taking foot passenger to Ostende leaving from here. Also the Hovercrafts are gone. The tunnel really changed the world here. Dover, not long ago the focus point of traffic between England and the continent, has become sleepy. The only ferry went the short way to Calais. On the French side, Syrians were camping and hoping for a chance to go over to the UK. Also Calais changed. It became sleepy too, but it is better not to gaze, but take care of fellows waiting for a chance to hit and run at least for your bag. Good reminder to put the pocket knife back in reach for quick reach and adequate response. The train to Bruxelles leaves every few hours from Calais. The one to Paris more frequently. This time going via Bruxelles was the train to take back "into the continent", as the English sometimes like to call it. 

8bis, rue Saint Hyacinthe

In Paris I walked along my old commute from the Metro Tuilleries to rue Saint Hyacinthe where I lived during my early time working at Bosch. My office was in Louveciennes though and I was commuting against the tide out by Metro and RER in the morning and back in after office hours when most went back out of the city. Most of my landmarks are still the same: my running route along the Seine and around Jardin des Tuelleries, the Opera Garnier, the baker, the market. Most restaurants changed owners. But the patterns stayed. This time, again I could not convince myself to go up the Eiffel Tower. Perhaps I will never make it up there. But I also don't really know why I should. 

Haute Ville

Special geography, making the castle already naturally a defendable stronghold, and clever policies sustained Luxembourg a sovereign state in Europe. Except a vanished steel industry in the South of the country, in Esch-sur-Alzette and Differdange, and agriculture in the North, there are no natural resources to exploit. Still Luxembourg has a GDP per capita around US$ 80 000 which makes it at times the world's "richest" country. Before favorable tax policies and banks which back then still kept their secrets, started to transform Luxembourg initially into what it is today, I spent a big part of my childhood here with my family. Then it was different. With my cousin, I strolled mainly around the mining and processing facilities of the Arbed around Differdange, explored shafts and tunnels and already experienced "open borders" by ignoring checkpoints and making our ways to France through the forest. The city of Luxembourg at that time, in the early 70s, was much less wealthy than today. The "Grund" in the Petrus Valley, just at the foot of the escarpment on which the Haut Ville is positioned, was still one of the town's poorest quarters around the city prison. Arriving the town by train and walking along the streets towards Place d'Armes, was a route through deteriorated streets. Now Luxembourg is a vibrant, international and nearly cosmopolitain city. Now the "Grund" hosts European company head quarters like those of Skype and Amazon, and is a place of entertainment and culture. I liked my recent stop over in Luxembourg a lot. Just one night though and then off on the TGV to Paris. 

Dear Diary, I have to stop writing to you.

Of course every day has nice moments. They appear spontaneously, and so I will note them down or capture them in other ways as they come. But looking out of the window today, seeing another Kafkaesque scene of the city in constant smog, I decided not to keep a diary for the time being. Like that, the time in Beijing will blur into the grey shades that it was. There will be memories, letters, photos, sketches and other artifacts - but no continuos record. 

Morning view from the window. Sun is coming out decomposing the smog into photochemicals. It is 35.3 Celsius outside the window and an AQI of 235 ("very unhealthy").

Yun Meng Shan hike

At 7 in the morning, with humidity above 90 % and an outside temperature reading over 30 Degree Celsius in the morning and a thick layer of clouds above the city of Beijing, it was obvious there will be quite some rain coming down. But we sticked to our plan hiking up the Yun Meng Shan, which is about 85 km North of town. In this weather, every view looks like a Chinese painting. The same hike on a clear day, must have a completely different character. A good reason to come again and exactly take the same paths. It is a very nice route and you may download the GPS log here in gpx- or tcx-format.

Miyun Jidaowan Canyon

We have been lucky with the weather in recent days and it is always a pleasure to make it out of Beijing on the weekend. For that you can hike from the Yunmeng Mountain up over a saddle North and then follow the crystal clear river through the canyon towards the reservoir. You will see some Watch Towers which have been built there "by accident" off the Great Wall in the Ming Dynasty (don't get me going!). 

The trail is bushy and in some sections quite steep. There is only one village left, as all the others have been washed away by a flood about a decade ago. It is unlikely you don't see anybody in the remote places. I recommend to upload the exact log on to your GPS (gpx-format, tcx-format).  

Piano rental in Beijing

In the morning we went to the other side of of the city, to the neighborhood of the Central Music Conservatory, to rent a piano. You can get them from 120 RMB per month, if you sign up for a year. The Yamaha piano sounded softer though, so an upgrade to 150 RMB (18.76 EUR or 24.40 US$) per month was very appropriate. It includes a piano chair and a cloth cover. Delivery is free, tuning (any time needed) included. Let me put this into relation: it's about what I would pay for my mobile phone package per month (if I would pay for it). For the price of an iPhone 5, you can rent a piano for nearly 3 years. Usually iPhones break after one year tough. The economics of happiness is an interesting one. 

Why does the world have Rice Cookers?

After having cooked or steamed rice for decades without any problems in a pot, I recently was surprised that many Chinese I talk to don't know how to do that. They need a rice cooker. These are electric appliances, which do absolutely nothing else, than what you do in a normal cooking pot. Some of them have some digital functions and beep around and flash some LEDs. Mainly they just control temperature and time. Some of them also allow steaming. But still on first sight rice cookers seemed to me as completely obsolete.

But I was wrong. Rice cookers in China reach back to a time in which many people were still cooking on a coal fire - actually, many still do this today. As this was the only fire place which can heat a Wok to cook other things than rice, it was convenient to have a self sustained rice cooker, which could do the job in any corner where there is an electric plug. Also, many more modern electric and gas stoves actually only have 2 fires, and not 4. So, again a rice cooker helps a lot to keep these for cooking other dishes than rice.  

Rice cookers go back to 1937 where they were used for mobile kitchens in the Japanese Army. In 1945 Mitsubishi brought the first civil electric rice cooker to the market and in the 1950s Toshiba followed with the first fully automated rice cookers. 

Interesting. But having a gas stove with 4 fires, I stay with my pot for now. 

Whiteout on Mount Hallasan

It has been more than half a year since I last visited Jeju (the island off shore the Southern tip of Korean Peninsula), back then testing my new hiking boots. This time on Mount Hallasan, no ice was on the summit, and just a normal pair of shoes were enough for the 1600 meter ascent. But this week the peak of the mountain kept itself mostly hidden in clouds. After leaving the forest, you cross a beautiful alpine landscape with a unique fauna and flora - many species indigiounous. Strong winds were driving patches of clouds over it and left a quick change of bright sunlight and whiteout. I was told that this is the environment surrounding immortals in Chinese believes. I always feel high mountains have something immortal, no matter of light. Perhaps, it is because we are closer to the sky.

Jeju is a sizable volcanic island, with Mount Hallasan as the major shield volcano. But there are many more volcanoes, tuff craters and lava tubes. A paradise for volcanologists. The coasts are mainly steep and rocky, and the few natural beaches are black sanded. The water of the natural springs tastes of different minerals, depending on the very specific location. Luckily Chinese tourists are absorbed by the Casino and the shopping malls and other attractions close to the airport, which preserves the rest of the places from their impact.

From Jeju's East coast there is a ferry connection to U-Do island, which takes about 30 minutes. It is a car ferry, which also carries the trucks transporting out the garlic harvest, which is a major crop there, and a fixture in Korean cuisine. Arriving U-Do you can rent a motor cycle and circumcise the island in less than an hour. U-Do is offshore-offshore Korea, and by this reminded me of Lamma Island, which was my home in the South China sea for five years, before I moved to Beijing. I know that for many people "offshore" is mainly related to a special kind of Financial Service industry which is making use of special rules away from major jurisdictions. But for me, "offshore" is a lifestyle away from the buzz of big governments and consumerism. It can be found on islands, in forests, on mountains and even in some cities - probably not in Beijing though. 

Helga Besler (1939-2012)

When I recently visited my Alma Mater in Cologne, I had to learn that Prof. Dr. Helga Besler passed away in spring 2012, aged 73. I knew she was Emeritus, and we still wrote for many years, but the last ones I lost track of her. She did not use e-mails, because she always said, it's bad for her eyes, and the last letters stayed unanswered. I blamed this routinely to the postal service, and did not even think her time could have been over.

​Helga was one of the most influential people in my life and I worked for her as a teaching assistant at the Department for African Research of The University of Cologne, before she encouraged me, even without meeting all requirements of a formal graduation, to go overseas and work as a scientist in the Mining Industry. She supervised first my thesis attempt of using Monte Carlo Models to simulate structures of karst caves and determine their age by that. I choose the topic and approach myself, never had ever tried it, and it was an ultimate failure. Then she supervised my second attempt, in which I validated and refined mathematical models for airborne particulate dispersion, which finally succeeded in 1992 and received the Dr. Prill Prize. I learned from Helga how to conduct research, stay on top of scientific knowledge and how to conduct expeditions to the planet's most remote places. 

There is much more to say about Helga's scientific heritage, expeditions and how she mastered her way as a woman in a domain of men. But this will be the topic of a colloquium in summer at the University of Cologne. Helga was for me more than a Professor, but a mentor in my (very) wild days. And she shaped my view on how Professors should be, and ultimately how I am as a Professor myself. 

​I well remember the last thing we did together in the mid 90s. Based on the experience I gathered during my PhD, we wanted to use radar data to better understand precipitation processes in the Northern Sahara. For that we needed access to the Egyptian air defense radar logs. We never received this (of course), but the negotiation with Egyptian military attaches and high ranking air force officers, was quite an experience. Thinking back to these situations, being surrounded by fierce Arabian men who did not take our "science story", but thought we are Israelian spys, I have to  say that my first real lecture in leadership I received from a woman.

My home is my castle

Last week took the chance to go down the Rhine by boat from Oberwesel and visit the forest I grew up in. The region now became World Cultural Heritage. It is not just the country of castles, knights and witches, but also the setting for many Germanic myths of gods and heroes. I enjoyed the quietness, fresh air and flair and the feeling of being home.

Mango unchained

Like in many other South-East-Asian counties April 13th was the beginning of the traditional New year: Songkran. ​Like the Chinese New Year, it was in the past was based on an astronomical calculation which varied each year. But now it has a fixed date. People go to the temples and it was an interesting tour to Ayutthaya, about 1.5 hours drive North of Bangkok. The most obvious part of the party is though that everybody is throwing water at everybody. Nobody who is not at least equipped with a water gun, bucket or a hose. People roam around on pick up trucks and perform heated water battles in the streets, and it is really great fun. 

​Ayutthaya was the capital of the Ayutthaya Kingdom which was founded by King Ramathibodi in 1350 AC and destroyed by the Burmese Army in 1767. The ruins are accessible in different sites, but also many relicts are slowly taken by modern life. It is a very impressing place to go to and reminds of Angkor and Siem Reap.

Singapore

Willian Gibson traveled to Singapore in 1993, to explore whether the future of technology would be coming the small city state south of Malaysia . He summarized his impressions in the Wired Magazine in an article under the title: "Disneyland with Death Penalty". He starts: "It's like an entire country run by Jeffrey Katzenberg," the producer had said, "under the motto 'Be happy or I'll kill you.'"

Yes, Singapore is a strict place. But perhaps Mr. Gibson, at the time he wrote his article, never really experienced how to live in chaos and corruption. It is definitely not making you more progressive. I admire Singapore for firstly for surviving at all, and for becoming a prosperous place to live for everybody who wants to contribute. On the other hand it has no tolerance to people who do not want to contribute or disturb the system which has proofed to be successful. This is why, I was told, there is a lack of "creative destruction". I know what this term is meant to say. But most destruction I have seen, was simply destructive - and not creative at all. This is why I understand, a place like Singapore is only experimenting carefully with it.

​I enjoyed escaping Beijing for a few days, breathe clean air, eating un-poisoned food and meeting nice people. Like in Hong Kong, most people who come to Singapore have an interesting story to tell and experiences to exchange. And also like in Hong Kong, the local people, are very much occupied by making money - and that's it. Singapore in contrast to Hong Kong, has not beed a refugee for people escaping from Chinese Communism. It has attracted people by the model itself and offering an alternative not just contrasting one big oppressive neighbor. There are many other differences between Singapore and Hong Kong and the closer you look at it that the often made comparison between these two places is comparing apples and oranges.  

I was also looking at Singapore from the perspective of moving there myself one day. And of course, I am just at the beginning of my exploration of terms, but it is definitely on my short list.

Honey Walk

Unfortunately, I had to cancel this year's Easter egg hunt. I always thought that it would be a hide and seek game with the eggs. But now I learned that it is really called "egg hunt". Imagine the sound of horns in far, dogs running though the woods, horses, gunfire - and this time we are after eggs. Sounds a bit like Monty Phython to me. But anyway since I am in Beijing, the whole world sounds like Monty Phython. So why not that one also?  Not sure, whether it is also a comedy, that North Korea declared yesterday to be in "state of war" with South Korea. Kim Jong Un, commonly known here as "Prince Fatty", is quite a clown though. Let's hope it is just another of his jokes, and we just don't get his humor.

Yesterday I had a nice walk with friends in the mountains West of the Great Nation's Capital. Still a bit overrun, because it is too easy to reach. But it was good to be above the smog for a while. Passed bye a honey farm. The peach trees are not blossoming yet, but was told that end of May the honey here is best. Not really organic. Amazing the bees don't die in the cocktail of smog and pesticides. Must be a special breed. Unrefined honey is said to be good for the immune system. These bees at least must have a "super immune system". So, this honey must be really good. I tried. It's sweet. And yes, it is unrefined. It really is.

Winter and spring in one day

Winter and spring are wrestling with each other these days in Beijing. This morning, surprisingly, winter was back with 15 cm of snow which fell over night. Then in the afternoon, spring was again on top. The walk to the office felt like a Christmas walk, even now we are already coming to the end of March.​

Commencement

Yesterday was their day. The first 14 students of the Tongji-Mannheim EMBA graduated, and proudly received their degrees handed over by the Ambassador of the Federal Republic of Germany and high ranking faculty of Tongi and Mannheim University. Now our young programme has the first alumni. And this core is going to grow quickly. I have been with this programme from its moment of birth until the first Commencement now and it became an initiative close to my heart, but empowered by the brain. We are getting quite some recognition now, not just on a University level, but also by major corporations. As a very unique alternative to "American Style" EMBAs we have even been covered on a channel of the Chinese Central Television yesterday. It is a diverse and academically rigorous English taught programme made and delivered in Germany and China. It was often described yesterday as a bridge connecting the two economic epicenters in Asia and Europe. But it is of course not about Nations, but about minds and people coming together. My congratulations to the graduates, all the best to the current students, welcome to the newly enrolled participants and thanks to all those who made this happen and support it. I am personally looking forward to contribute on the academic and management side, as much as my schedule allows it. Our "alumni management system", might be simple so far, but it is effective: for example you can just give me a call.

Letter to a small lady

I knew it. Some children are not stupid. Yesterday, I had a conversation with a young lady which started to compile her own little "constitution". She was given a set of Golden Rules by her teacher, but there were major points she did not agree being valid for her. She wanted to define her own rules. But as the topic is complicated and she acknowledged not to have seen much yet, she decided to issue a tender to friends and family and request their proposals. I was really buffed by this approach. And of course, I decided to submit my contribution. I remember reading Earl of Philip Dormer Stanhope Chesterfield's Letters to His Son on the Art of Becoming in Man of the World and a Gentleman. But they were written in the years 1753 and 1754 and I was wondering for a  whether today, in the world of Hello Kitty, it is still appropriate to talk seriously to a child. I still decided to give it a try. She requested me to put down a set of Golden Rules for her, preferably also things which she does not want to learn the hard way. And I really had to laugh when I heard that. Proposals should be not longer than one page A4 by today's deadline. So, this is what I wrote.

​Rules for a small lady

1. Your purpose is defined by you; not by society, family, and teachers.
2. Thinking is free and without borders. The driving force is curiosity. Expression is part of thinking. There are no taboos of thought. Stay away from ideologies, superstition and religions.
3. Ask questions. The truth is the assumption that has the highest explanatory power. Never lie. Know what you talk about, but don’t always say all you know.
4. Your freedom may expand as large, as it does not limit the freedom of others. This includes your freedom of speech.
5. Independence enables your freedom of choice, and defines the size of your world. Only depend on those you trust. Have the means and abilities to defend your independence.
6. Be trustworthy but don’t trust easily.
7. You are responsible for yourself and for those whom you made trusting you.
8. The smallest unit of society is the individual. You have the freedom of choice of your community. You have the duty to contribute to society. The human dignity is untouchable. You have the duty to defend anybody against repression, injustice, exploitation, violence and environmental degradation.
9. Do not take full advantage.
10. Manners are important to interface with your community and a symbol of your own dignity. Be graceful. Never be a sucker. Never know the underdressed.
11. You can choose freely who you respect. Do not obey orders without questioning them. Seniority, formal positions, rank, and power are not principles that you have to follow.
12. Health is the foundation of your life. Do exercise and sleep as much as you need.  Walk on foot every distance under 2 km. Do not use escalators or elevators. Never eat things that grandma would not have recognized as food. Also don't eat things where you can't pronounce the ingredients without hesitation. Avoid restaurants, in which you don’t know the cook.
13. Take your time. Do things right. It is better to be effective than efficient. Low efficiency makes hectic, high efficiency makes stupid.
14. Money is a resource enabling to do things and not the other way round. Don’t sell your life for no purpose. Do not waste resources, no matter whose they are.

Going 33 km on one charge - no range anxiety

We constantly have discussions, which is the best way to move in Beijing. Quickly the topic comes to electric scooters or e-bikes, which are becoming more and more popular. And then comes the question, everybody answers differently: "How far can you go with one charge?"

Today, I did not talk about it. I did it. I went out to drain my bike to the last electron. It is a hybrid, which can be driven fully electric or as a supported bicycle - a so-called "Pedelec". The advantage to a scooter is, that you can extend range by pushing into the pedals and also, should the battery be really empty once, you can at least still get home. The manufacturer does not give information on the battery capacity or the power of the engine. Just the salesman said something like 25 km. So I expected this to be Chinese 25 km, which then should equal about, let's say 12 km.

I started with a full charge of the about 6 months old lithium ion battery and rode off into the haze through the Hutongs of Beijing, passing Tianamen Square and back to Dongzhimen.

Me, my clothes and water bottle made 90 kg payload. There was not much wind and temperature was around 20 Degree Celsius (that defines the battery capacity, which is lower at low temperatures). The route taken was quite flat and speed was sometimes limited by the traffic. As a result, the range was a surprising 33.2 km on electric drive. Then the engine suddenly fainted and I only had to make a few hundred meters on a conventional bicycle. Looking at the GPS track below (red line in the map), there is one outlier in the measurement which goes up to 120 km/h, which is of course an error. You can go quite continously at around 20 km/h and the average moving speed is with 13 km/h about what you can make with a car in Beijing. Quite good. Impressed.

Smiling at the grim Beijing

​Morning view out of the kitchen window. It is a reasonably clear day and everybody and everything alive is awaiting spring, which is on its way. A short transition to summer.

Little journey to the West

One advantage of Beijing is, that you can easily get out. The Megcity has mountains in the North and West, which mark a sharp boundary between 1950s style coal power plants and a beautiful natural landscape. You might want to avoid tourist destinations, but still use public transport. And actually, this is quite well possible.   

For example take the subway to Ping Guo Yuan (=Apple Garden, but don't be confused when you don't see any apple tree). It is the last stop of Line 1 in the West. Then walk 300 meters further West, until you see the bus stop for line 892. The bus service starts at 7:00 o'clock in the morning and runs very frequently. Stay on the bus for about 2 hours and get off at at the Fa Cheng bus stop, at N40 00.113 E115 47.949. This is a good starting point for a hike over the mountains and the decent to Jian Yuntai (N39 56.132 E115 51.110), for the bus 929 back to Ping Guo Yan station. The whole hike will take you around 7 hours. The last bus at Jian Juntai leaves at 17:40. If you miss that, you are (!) in trouble, as this is just a remote village which has no (!) other transportation.

The route gives a beautiful outlook over the mountains. There are nearly no people up there. The villagers do not grow nuts or fruits like in other rural regions around Beijing. Still the terraces along the slopes witness an agricultural past here.   The trails are just kept open by a few hikers per year and you need a thorn proof jacket. Strictly stay on the trails, which are occasionally steep and going along fringes. Hikers here use 435.000 MHz and  437.900 MHz.
