[LCC] Finally, I'm on RTTY!

[Mark, K5ER]

Dallas, Charlie and Don,
         Thanks! I've been running N1MM, and I d/l the MMTTY "plug-in". If 
I type "RTTY in the call field, or simply open a rtty contest in N1MM, 
MMTTY automatically opens. Now that's easy.

         To get started, I used AFSK, and made an easy Qso the other night. 
As suggested, I looked at RTTY mode on the Icom and agree that it gives FAR 
superior filtering, so I need to look at going to FSK. That brings me to a 
question, or two regarding hardware, which I didn't see covered on the web 
site.

         Like many, I like simple. My normal setup is:
Heil headset runs to mic input of sound card. Speaker output of sound card 
runs to mic input on DX Doubler (SO2R box). With one keystroke, I can swap 
which radio I send mic (or recorded wav files) to. Normally listen to audio 
of both radios, but can switch to one at a touch, if necessary.

         Back in 2002, I, along with several others built a project from 
the March 2002 QST, a soundcard interface specifically for Icom radios. It 
plugs into the accy port and allows PSK (or rtty, or cw decoding), to work 
with one radio. So, the other day, I simply plugged the audio line from the 
interface to the "line in" of the sound card and now I can RX rtty from the 
left rig, and send either AFSK or voice to either rig, ie. my previous SO2R 
setup was unchanged.

         If you guys are running SO2R RTTY, do I assume you have TWO 
instances of MMTTY running? Virtually all sound cards have stereo input on 
their 1/8 jacks. Hardware wise, do you run left radio audio into left 
soundcard input (maybe tip and barrel) and right radio audio into soundcard 
right input (maybe ring and barrel), OR do you run two separate sound 
cards? I think Charlie even once mentioned separate computers, which means 
no right/left switching. Guess having them networked would eliminate having 
to continuously sync time and merge logs when done. For my setup, I really 
don't want to have to use two computers. At least I don't think I do. Since 
I've been successful with one computer SO2R for both ssb and cw, I'd like 
to do the same for rtty, if possible. Guess basically, if I'm going to set 
up for FSK, I may as well get it set up for both rigs, since all those  in 
the know say its the easiest SO2R mode.

         With the DX Doubler, it gets its commands from the Parallel port 
cable. By design, it allows toggling one pin to send cw to the selected 
radio. Can I break out the signals needed for FSK from that parallel port 
cable and not have to use one (or two) extra serial ports?

73,
