This morning I breadboarded the 10 MHz BFO for the BITX20 transceiver. I’m glad I did too, rather than just begin building. This allowed me to make a couple of mistakes, like putting the transistors in backward, that could be […] ↓ Read the rest of this entry…

I finally got around to correcting the ID’s on the 5.23 repeater. It was a good excuse for testing out the new Wouxun radio I got at work. (I love it!) This will document that programming for future reference. Maybe […] ↓ Read the rest of this entry…
