I have posted these before, but people keep asking about the settings to
use for RTTY on the IC-7600 with MMTTY. So this post provides my latest
settings. This article provides my latest MMTTY settings screenshots. I am
using it with N1MM+ Contest Logger. If you are having trouble using MMTTY
with another program (N1MM+ or other Logger or Rig Control program), you
may want to get MMTTY working standalone first. There are other articles on
this Blog that talk about IC-7600 RTTY and I suggest using the SEARCH tool
to find those. You must have the Radio Settings correct. You should be
using a Mode like LSB-D1 on the Rig and the corresponding DATAMOD (DATA1MOD
if using LSB-D1) setting must be USB. This is found in the SETACCDATA1MOD
menu item




This article is only for using the USB connection between the 7600 and PC
and using AFSK RTTY. Sound is generated and decoded by the soundcard
internal to the 7600. Note that the RECEIVE path uses the Microphone
settings and the TRANSMIT path uses the Speaker settings on the PC. It
makes sense if you think about it, but dont go tweaking the Speaker
settings to change the TRANSMIT drive power. It wont work.




It seems that my biggest problem is returning to RTTY after some time using
other Modes on my rig, and nothing will Transmit. While this is usually a
SETTING that has mysteriously changed, I have also heard there are times
when the IC-7600 is not being keyed by the Soundcard data, that are not
well understood. I will just say that every time this happened to me, I was
able to get it working, eventually.
