Expedition to Assy-Turgen Observatory

Expedition to Assy-Turgen Observatory

Pre-history

Since I got my new Finnish OH7O callsign one day before the event (switched from an automatically assigned OH7CYO) when I was already in Almaty, Kazakhstan, and because I was lucky to get UN/OH7O temporary call sign from a local regulator on the next day, I was eager to use them in the air immediately. 

Thus, I quickly built an elevated 1/4 lambda vertical on Friday late evening Aug.25th, and started searching for a spot to test the rig and the newly built antenna. And, of course, most of all, I wanted to make the first-ever QSO with the new callsign OH7O or, to be more precise, UN/OH7O.

I wanted to experience as noiseless air as possible. Thus, the place must be remote but still reachable by car since it was 10pm when I sort of finished with the antenna.

One of the problems with “nice remote places” is that you can drive several hours to them… and then find a lock or something. It was a very possible scenario until I reached the place. And I reached the place only about 2 a.m. on Aug.26th, Saturday.

Another risky point was that I haven’t worked from the car before and I wasn’t sure whether the electrical grid of the car will survive. I didn’t have time to purchase an external battery.

By 3:30am, I finally erected the antenna and tested the SWR. It was a pure luck right from the first attempt 🙂

People asked about the location… well, this is the location:
