How do you K3/N1MM users interface the MMTTY engine?
Assuming you are using FSK (FSK D), you need two serial ports. One
port is used by N1MM Logger for radio control (connected to the K3
RS-232 port), The other port is the N1MM Logger Digital port -
the TxD line drives an open collector
Or you can just use AFSK + VOX and not worry about it.

Joe,
I ran into the same question a few weeks ago.
Now i'm using N1MM-MMTY-K3 in AFSK, settled for that because it is easy
and experts say it is a clean transmitting signal.

to control the K3. I have N1MM starting the MMTTY engine but it cannot

the radio because the COM1 port is already being used to control the
radio.

You can use the same port for PTT and control but use must use a separate
port for FSK keying.

I strongly agree, PROVIDED that you are careful to properly set audio
gains in your sound card and in the radio.

I also asked this question on the N1MM reflector. I am using N1MM COM1 port
to control the K3. I have N1MM starting the MMTTY engine but it cannot key
