To see how N1MM is setup take a look at this post: ICOM 7300 N1MM LOGGER PLUS SETUP MMTTY Icom 7300 RTTY FSK I’ll post a video clip in a week or so bringing this all together, ie., PSK31, CW and RTTY (FSK). USB Keying (CW) is set to DTR and USB Keying (RTTY) is set to DTR. I changed DATA MOD to USB because I’ve been operating PSK31 with the sound card. In the radio there are a few settings to be made. One CI-V for rig control and the USB for digital modes including FSK and CW! (I am assuming that you have already downloaded the USB driver from Icom for the 7300 and have installed it. There are other advantages with FSK, but I won’t go into a lot of detail. Using FSK, when I tune to a signal using the Icom 7300 spectrum scope, it aligns perfectly in MMTTY’s band scope. It’s completely outside the band scope and I have to go searching for it. In other words when I use the 7300’s spectrum scope to tune to a signal and line it up, it’s not in the band scope of MMTTY.

Why FSK? Well there’s the sound card issue with AFSK and I noticed after setting up AFSK on the 7300 that the signal on the spectrum scope is not aligned with the signal on MMTTY (N1MM Logger). I’m not a serious contester, more of a casual contester. N1MM is my favorite logging program for contests.

I have FSK setup now using MMTTY which of course is used by N1MM Logger.
