Thanks Vojtech,
I'm getting a grip on this now, maybe an internal beta of my DM780 software
with PSK / RTTY / Olivia by the end of May. It's working on receive now but
needs refining.

Then DO IT and let the FCC rule .
Just remember for your long distance digipeaters to
work the band must be open .
unless your going to use ECHOLINK and if so whats the
point ?

So, , how would one actually repeat a signal ?

MFJ sells a MFJ-662 pocket repeater for $79.95. Basically it is a digital store
and forward box that records up to 32 seconds of audio and then re transmits it
once the receiver is squelched or after the 32 seconds. They claim it works
with
any rig including HTs and is legal in any band but
If we are talking about DIGITAL VOICE, I believe the answer is receiving
the signal and demodulating it to the DIGITAL baseband stream, verifying
the stream integrity, and then, if tit passes the integrity test,
reshaping (regenerating the pulses) and remodulating. No decoding or
converting
Here is a related idea: We have seen with JT65a that sometimes when we
think the band is closed, it is just very poor instead. W1AW, which one
can sometimes hear all lone on the high bands (due to its power and
antennas) shows us this as well. I..e., what we assume is no
communications may
The problem is that if this is a store and forward repeater you will
accumulate too much time delay.

I imagine this is intentional on the part of the programmer
Actually, my point is just the opposite. There is delay, but I don't
think it accumulates.
JT65a on HF shows me 2 things:
1. Hams will spend a minute per over to get a contact when the band is
dead
2. Timed TX start is possible and gives a great value
One of the problems of digital speech is

I imagine this is intentional on the part of the programmer - you have
to hit enter or maybe space
Hello Leigh,
Guess it depends on the operator, but do not think time is an issue
if the end result is worth itin the EME and MS world, an HF JT65A
contact speeds along, usually. Not to mention endless time some spend
in a pile-up, waiting for a net to come around to one or listening to
