Rich,
Yes, I have RTTY working in AFSK mode.
I am trying to make it as LEAN as possible.
If MMTTY can bring the FSK as a digital signal which can be fed into the
K3 as digital signal (0/1) that would be nice and Lean. Just as N1MM and
CW over one cable for the K3.
Of course I can use two
Hi all,
I can control the K3 over the rs232 cable. No problem.
CW en PTT also works over the same cable with the PTT-KEY settings on.
VERY NICE!!! Keeping the winkey as a backup now.
Now the question: Is it possible to run RTTY in FSK D over the rs232
cable directly into the K3 just like

Arie,
I assume you are asking whether it is possible to use the RS232 port to
send FSK RTTY in FSK D. If so, the answer is yes. Below are three
theoretically possible methods - only the third one works, and only from
a limited selection of software, but it is possible.
The K3 does not accept
Thanks Rich, clear answer.
Well...
The idea was to use LP bridge.
Send the RTTY keying via a com-port from MMTTY, and control the rest of
the K3 via another com with N1MM logger. Since there's only one cable to
the K3, all signals should run over the same cable, just like the
combination of
Arie,
You will have to ask Larry Phipps if that MMTTY stream is implemented in
LP-Bridge.
RTTY via DTR is possible, but would require the one transistor keying
circuit to drive the PTT-IN pin on the K3s ACC connector. Of course,
LP-Bridge may or may not support DTR through its interface.
The MMTTY/EXTFSK combination can use DTR on a serial port for FSK
keying, but I have no idea whether EXTFSK would work through LP-Bridge.
Without EXTFSK, MMTTY uses TxD for FSK keying, not DTR, and that cannot
be shared with radio control.
If you are already using MMTTY, by any chance does
