I have my Bitx40 on the air and all seems to be going well. Good reports just that the signal is not 40/9.
- I suggest have two wire bundles with a red and black wires instead of the brown black. As this would prevent an accidental connecting the right wire to the wrong connector. In the board I have the PTT header is right next to the header that is the main power to the board. If you got those two connections wrong say after removing the connectors and re-installing them a lot of magic smoke.
- Provide a note that if you hook up a homebrew DDS (and not your board) to be sure to include an isolating cap, as you are feeding directly into the base of one of the transistors.
