OH7O Blog

The 6-element Yagi monoband for 10-meter is my latest love 🙂 It gives about 1-S level gain as compared with Moxon and about 1-3-S levels of noise reduction.

I wanted a stronger TX power for quite some time. Moxon antenna works good enough to hear remote station. But I wasn't not heard well with the default 100 W... Well, now everything looks much better TX-wise 🙂

Expedition to the lake Issyk Kul with freshly received callsign EX/OH7O. Yurt camp right on the shore, new Moxon for 15-meter band, many QSOs.

I love the vertical 1/4-wave antenna for mobile operations for the DX performance and its practicality. However, the gain of Moxon and its relative simplicity disarming. I love Moxon!

Playing with a magnetic loop antenna for 14-21MHz. Comparison with a raised vertical quarter-wave.

Setting up the system, tuning, testing, and tuning, modifying, experimenting, and testing again is one of the main funs for me

It was easy and took just 24 hours for me to get the local temporary license. Most likely, it is possible for you to get it as well even on a short visit

The best birthday is a field day 🙂 It was 70 km north of Almaty, Kazakhstan, near Kapchagay Reservoir.

Return to the plateau Assy and an observatory - now with my wife Natalia, new antenna, and a drone.

Expedition to plateau Assy and an observatory there: my first ever field day and first ever QSOs using UN/OH7O.
