Vic,
It was the v5 code that transmitted a 10MHz signal.? The v4 still had the AM zero beating to calibrate it.? Regardless, Nick is using the KD8CEC firmware, which does not have the transmission of a 10MHz signal for calibration.
Nick,
Does it go into transmit mode when you press the encoder without entering the "yellow box" settings window?? Can you try duplicating the issue when connected to a dummy load?
The second question is because a simple wiring error would only key the transmitter while pressed.? An RF feedback issue could lock the transmitter on after the encoder is released.? To do the actual calibration, you will need an antenna to receive the AM signal unless you have a calibrated signal generator that can be received while connected to the dummy load.? You need the white noise of background static to tune the BFO.
BFO tuning aid:
Wiring instructions:
I recommend installing the 4.7k pull-up resistor on the underside of the Raduino board, as was done for the v6.? I have had the resistor on the keyer jack come off when working on the rig causing flakey operation until I found it.
