Lately I have lots of problems with my home made 23cm transceiver. But before I will go hunt for solution I decided it was time to replace the 19-inch casing with something more decent. The 19-inch housing was way to big and not practically because of the thick steel.
So I wanted a somewhat smaller case, preferable made of aluminum. I always liked the cases of MicroHAM so I looked up the dimensions. It could fit in the same dimensions as the USB micro Keyer II.
So I made a design based on those dimensions and cut and fold some aluminum at the club. A lot of drilling and filing had to be done to fit everything. But I’m pleased with the end result. Unfortunately the problems with the transceiver didn’t disappear with the old housing, so I still have to find out what is wrong with it. Since the LF-sound screams when I turn on the volume, I assume it has something to do with the LF-amplifier (LM386) or the radio-chip (MC3362). I tried to reach out to the designer of the transceiver (Bas PE1JPD), hopefully he can help.
