Hello all,

I'm looking for a way to adjust the T/R delay of my AL-811 and wondering
if anyone knows of an online source of info...so far, I haven't been able
to turn one up.

Specifically, I'm looking for a way to delay the transition from transmit
back to receive during CW in order to minimize wear & tear on the relay.
Even at 25 wpm, the relay transitions back to receive mode after every
letter of my callsign. I'd like something less QSK-ish, for example to
just stay in the transmit position for the length od a word (or callsign)
rather than changing over after each letter is sent.

Thanks and 73,
