After my first cw contact, I noticed that the power output was falling down. The back of the radio was very hot and I think
that is because of the back plate its self. It is not like the one I see in the pictures. My back plate is made of
double side PC board that has holes in it. I think the heat sink properties of that plate are insufficient. I was able to fix
it by attaching a small fan to the back plate. Now, the power output is stabilized.
I was listening to 160 meters and tuned 3 kHz above the band and heard a shortwave broadcast talking about amateur radio.
I thought, How nice. I checked with another radio and that signal was not there. I read somewhere about Tayloe muxers and sub harmonics and checked 6.009 MHz. There was the station. Is there a way to prevent Sub harmonic reception?
How about reducing LO input drive to the muxer? Will that help or will it cause other problems?
I am very pleased with the radio and enjoyed building it very much. I have made many contacts with it already.
I have a Icom IC-7600 but enjoy the TRX2A better because I built it.
The layout and design are first class. Thanks for such a nice experience.
