[Elecraft] K4: No TX power in audio based digital modes

[Mark Musick]

Dave,
This question would be better asked on the K4 reflector.
It is located here: Elecraft-K4 at groups.io. This reflector is not associated with Elecraft, but Bob, N6TV (one of the K4 testers) answers many questions about the K4 and there is a files section that contains documentation on many K4 subjects.

New K4 seems to transmit fine in CW and SSB -voice.  But I cannot get more than a 2 watt  TX power out reading in AFSK.

N1MM+ w MMTTY used for generating AFSK RTTY signal.

Using the USB to PC  patch between computer and K4.

Audio TX RTTY signal is heard in K4 monitor.

PTT line functions (TX light goes on).

Low level rtty signal is heard on another rig in shack.

Under "menu", Serial USB-2 DTR is set to CW;  RTS set to PTT.

Rig control by N1MM+ seems to be working properly.

But, CW sent from N1MM+ does not key K4 in cw mode.

I imagine I am doing something stupid; I've done it before.

Thanks for any advice.


73, Dave, K2YG
