69855Re: ATU for ensemble rxtx
- Nov 8, 2012No, PTT by itself is not enough. You need a tone to be applied from the TX soundcard output to the Softrock. The output power is proportional to this audio signal. No audio - no RF output.
I use this setup (RTXT+T1 ATU) for WSPR, so I press the button on T1 when WSPR begins transmitting.
