Re: K3 & N1MM for RTTY

Another option for CW is CONFIG: OFF-KEY, this allows full break-in. Found it really useful in contests...

For FSK you need a second COM port and a simple transistor/resistor interface. Set both RTS and DTR to ALWAYS OFF on the second port.

It's a bit of a bear to get through it all the first time. I fought with the set-up for a while but got a lot of good help here.

I can forward a couple emails with some pointers I received... Works like a charm now.

Cheers,
Julius

Just do it:) In the N1MM "Configurer", under the "Hardware" tab, check
the "CW" box next to the port you've configured for the K3, then click
on the "Set" button, set DTR to "CW" and RTS to "PTT". Then on the K3,
set CONFIG:PTT-KEY to "rts-dtr".

Beware of this if you're considering SO2R CW with N1MM - it doesn't
like the same serial port being used for rig control and CW in that
case, but it seems OK with one radio.


> Also, I have FSK on another COM, do I set that up in N1MM or MMTTY?

MMTTY. You tell N1MM that you're using FSK under the "Digital Modes"
tab of the "Configurer" (also set TU type to "Souncard" there), but
the specifics of FSK interfacing is configured in MMTTY.
