    I have set all of my anti-thump thresholds to max and I still get the ping-ponging squelch tails. I've also tried all of the options (manual, vox, serial CD, serial CTS, serial DSR) with no real change. Sometimes when I raise them to max and listen, the ping-ponging stops until I transmit, then it starts right back up again. How do I fix this?

    Are you running the radio in duplex mode ?

    If so, Do not do that.

    I'm not sure that I understand. It has to receive the signal from the repeater on the output frequency to send across the internet to the other node. Then it has to be able to send the outgoing transmission from that node back to the repeater on the input frequency. I can't think of how that could work if I use only a simplex frequency.
