I can't help with your hardware TNC specifically, but for those of us using
a software modem, an update was required from the author (UZ7HO) to allow
PTT regardless of carrier detect. Since FS-3 is more-or-less constantly
transmitting, there will seldom be an absence of RX data. So, you may wish
to verify whether any adjustment is needed with your setup to allow PTT in
a full-duplex environment.
