K3 Software for RTTY

[Robert]

With the ARRL RTTY Roundup coming up, I'm having difficulty choosing a software control and logging program.



N1MM needs audio cables to and from the K3 for RTTY and yet the K3 user manual states “The K3 directly supports CW/PSK31/RTTY ASCII text transmit and receive via its RS232 port.” I do have the RS232 to USB cable installed . Am I not reading it correctly or should I look at another program? Suggestions are welcome.

You will need software that understands the KY command to transmit  
RTTY data (Baudot, not ASCII) through the RS-232 port.

RUMped by DL2RUM supports this, but even RUMped uses a software modem  
on the receive end (i.e., needs one audio cable).  Since you mentioned  
N1MM, you are most likely not using Mac OS X, which RUMped needs, so  
it might not work for you anyway.

I recommend that you set the rig and software up to use AFSK instead  
(either with AFSK-A or DATA-A mode depending on whether you use agile  
waterfall transmit).  Wire up a sound card to the K3 using two audio  
cables, then adjust the audio drive and VOX gain properly and you  
should be good to go.

  Robert,

While the K3 has the capability to do RTTY (and CW and PSK31) from an
ASCII text stream, there are few applications that support it.  K3
Utility does it, but that is not a logger.

You will probably have to use the audio cables from the soundcard and
use the AFSK A Data Mode.

Maybe someone else will know of a ham application which sends the ASCII
data stream over the RS-232 connection.

Just use N1MM with the MMTTY plug-in and be done with it.  You clearly have a computer, every compute made seems to have a sound card good enough to support this task.  Two audio cables, ASFK-A using VOX and you're good to go.  Be sure to set 45 BPS tho.
 
Pick a mark frequency and be sure to set the K3 and MMTTY to the same. (I prefer 915 as I like to listen to the audio and other tones are too annoying.)

KComm does it. I've never particularly used it though since I find the point and click method using a soundcard waterfall more convenient.

The OP wants to operate in an RTTY contest.  He needs to run the RX BW as narrow as possible, 200-300 Hz.  Point and click has no utility in this kind of operation. Likewise, nix the NET and AFC options.  If running, turn on the RIT.
