Hi Bill Sure Its putting a tone on the unused audio channel when in Tx So if data was on the Right channel, put an audio tone, doesn't matter what frequency, on the left channel (TX Mode only ). Has the advantage on simple rigs that you can rectify it, diode and a cap, and then use the recovered DC to switch the PTT, and if the tone is sent before the data , everything is already in TX mode so no hot switching. Has the advantage of saving using a USB/RS232 to switch the PTT line with DTR etc. and keeps it very simply to use
Hope that makes sense Bill.
