bitx20 v3 build – t/r switching
I haven’t done much on the bitx in the last few days, but I did put in a 12 volt relay to do the transmit/receive switching. All I did was glue the relay upside down and solder a diode between the relay coil.
Right now I just trigger it by touching that loose red wire on the right to one side of the relay coil. I played some audio from my phone through the audio amp and tested the switching and it is working as it should.
I’ve wound all of the toroids I need to complete the build, but I still haven’t made a decision on the analog vs digital vfo. I think I am still leaning towards the digital vfo and I may even make this a multiband bitx. We shall see.
