Heiko, DG1BHA, and I decided to buy an Icom IC-9700 for the club QTH to replace our old venerable IC-7400 that served as our main 2 m radio for quite some years. We did some modifications to the latter for … Continue reading

Some youth work
Well, I didn’t post much personal information in this blog yet. After all it’s about amateur radio and related activities and not my personal life. But with this blog entry both combine perfectly so let’s get a little more personal. … Continue reading

In my recent CQ WWDX CW 2018 blog post I moaned about needing to do all station switching like BPFs, antennas, etc. manually when using the IC-7300. Driving home after the contest I made up my mind how to solve … Continue reading

A transverter interface for the ‘7300
After the quite good experience with the Icom IC-7300 during WPX-CW I thought it might be a nice idea to also try it out with a transverter on 2 m in the big VHF contest in two weeks. When searching … Continue reading
