Trekking with Radio in the Himalayas

The National Institute of Amateur Radio (NIAR) in Hyderabad, India where I work often deputes me for various assignments all over the country like Demonstrations, Radio Meetings, Training Programs, Emergency Communications, Dxpeditions, etc. As we always carry general coverage transceivers with us, it is always interesting to check the different bands from far away locations.

My latest assignment was to provide Amateur Radio communications for the trekking teams of the Officer Trainees of Lal Bahadur Shastry National Academy of Administration, Govt. of India, Mussoorie, Uttanchal State, North India which trains the future administrators of the country. As they don't have much communication during the trekking in the remote areas, this time they sought our assistance. Besides me, my colleague Mr. Sushil, VU2LFA and half a dozen other Radio Amateurs from the Academy were deputed for this. Special mobile permission was issued to us by the Ministry of Communications to use our radios in the trekking routes. We arrived in Mussorie on 21st September 2006 with lots of radio equipment. On the way in Delhi I accepted the hospitality of the active Dxer from the Indian capital, Mr. Alokesh Gupta and stayed with him.

The Academy is located at Mussoorie, a popular hill station about 200 kilometers north of Delhi the capital of India. It overlooks the sprawling Doon valley and the city of Dehradun, the gateway to the entire Garhwal region of the Himalayas. Spread over a ridge, 2000 meters above sea level, Mussoorie offers distant views of the holy and mighty river Ganga from one end of the ridge, and of the famous river Yamuna from the other; a stretch of around 19 kilometers.
The trekking was scheduled in such a way that 17 teams each consisting of about 20 members crossed the Garwal region of the mighty Himalayas for 10 days using different routes. On the 22nd morning the Academy campus looked like a bus station with 17 buses carrying the various teams were flagged off to their respective destinations.

I traveled in the bus accompanying the team which started their trekking from Naitwar in Uttarkashi District about 150 kms away from Mussoorie. We had to travel mostly through small ghat roads, thick forest and deep valleys which was an interesting experience for me. But it was also frightening when I observed the deep gorges next to our road.

In the late evening we reached the Naitwar Forest Rest House (termed as our Base Camp) located at 1380 Meters above MSL inside the Govind Wildlife Sanctuary & National Park which spreads over an area of 958 sq. Kms with an altitude up to 6323 Meters. Immediately after reaching there, I installed an Inverted Vee HF antenna & a VHF Ground Plane antenna and set up our Amateur station and contacted our office in Hyderabad and other stations. The rig was a brand new Icom IC 7000. As there was no electricity in the Base Camp we used the car batteries that we had carried and used to recharge it in a nearby house. The noise level was very low when there was no electric power in the area.

The trek members left early next morning and I had the company of an Assistant sent from the academy for the next 10 days. There were two "suites" in that Forest Rest House and we were the only occupants during the period.

Naitwar is a remote village in the forest in Uttarkashi District and is a starting/ending point for trekking in the area. Here there are two tributaries of the River Yamuna . Good water was available in plenty. We could see small streams in a lot of places. Last year there were severe land slides in the area causing lot of damages.

The houses were made mostly of wood. Local people spoke Hindi, Gadwali, Bengani, Nepali, Himachali and Tibetan. Some English is understood by guides and others. The conveyance was limited and often we could see people traveling on top of jeeps. Mules were used for transportation of material. Electricity is unreliable and lot of solar panels was seen along with DTH satellite dish antennas for TV reception. The nearest working telephone was about 12 kms away. Cell phone was also not working there. There were some VHF communication systems of the forest department in the area. During our stay the nights were very cool and days warm. It used to snow there in winter. We felt comfortable in our sleeping bags at night. For food we had to 'trek' about one km through the forest to reach the Bazar. Although there were some leopards, bears etc. in the area, luckily there were no untoward incidents.
Meanwhile Mr. Sushil set up the Amateur station in the remote Dharwadar Range which included trekking for about 13 kms. The radio equipment, batteries and other items were carried on mules. During daytime he had to operate from a suitcase in open air and stayed in a stone hut at night in a cold climate at an altitude of 4091 Meters above MSL. The snow clad mountains were visible clearly from his location. Not many people were living in that area. So they had taken cooks and provisions were transported by mules to make food arrangements for our trekking teams passing by.

The Amateur Radio contacts with trek teams were scheduled 4 times per day and progress of the trekking etc. were conveyed to the station in the Academy at Mussoorie, sometimes relayed by our NIAR Hyderabad station. At other times I used to check the broadcast bands keenly, especially the lower HF bands, MW & FM. In my rucksack, I had also brought the 2006 editions of World Radio TV Handbook, Passport to World Band Radio, latest schedules of AIR etc. to support my BC Dxing.

Last year also around this time I was in the nearby Holy Town of Haridwar on the banks of the River Ganges where we had come for Amateur Radio communication for the National Jamboree of Scouts & Guides and did some similar BC Dxing. We returned to Mussoorie on 1st October 2006 along with a team which ended their trekking at our place. I have been stationed at the Academy for some more time to give Amateur Radio training for the new Officer Trainees.

Here are some observations of interest observed this time.
