I actually did not expect the 7100's internal decoder to be as useful as it was but it spit out a large number of good decodes and popped up faster than the software. I told the rig to use it's second USB as RTTY output, then just set up a RX only TNC window directed to that 7100's second COM port.which is solely for D-Star Data and RTTY decode. MMTTY is being used as the main RTTY interface (bottom half of the DI window) 2Tone is being used as first RX only decoder (top third - 11) GRITTY is below that (12) and the third decoder (13)? That's the IC-7100's internal RTTY decoder. My Digital Interface window has a total of 4 RTTY decoders, yes, 4. I don't tell N1MM to QSY while simultaneously telling the waterfall to tune. I did this because I knew the chances of N1MM and SDRUno trying to send a command were low. So VSPE connects directly to the 7100's COM port then OmniRig and N1MM talk to that virtual com port. What I did, instead, was decide to see how it would play with VSPE. I could have done this by hacking together a CI-V level converter and using a second serial-to-usb bridge. N1MM doesn't support OmniRig meaning I'd have to figure out a way to get OmniRig and N1MM talking directly to the rig. The first issue had to do with rig control. Quite literally the only function is to be a nice, large, interactive panadapter. Spinning the knob on the radio moves the waterfall clicking on the waterfall tunes the radio. A simple circuit taps the PTT line and turns the LNA off when it goes low. The signal from the radio travels through a resistor to prevent loading the radio and in to an LNA. SDRUno sync's the VFO with the rig through OmniRig.which caused some issues. The SDRPlay is getting it's signal from the RF-TAP on my IC-7100 essentially I'm just tapping the signal between the main and PA boards. Granted I've got one of the old original RSP1 units, it still works just fine for what I use it for.

So starting with the top half, the SDRUno waterfall. A lot of this I wasn't sure was going to work, or how well it would work, until I actually started using it. So this probably looks very similar to the usual N1MM setup with numerous decoders and a waterfall except I've actually got 3 additional RX decoders running and my waterfall is from an SDRPlay. So I'll start with the screenshot of what I stared at for about 10 hours yesterday: I still to this day have no idea why I'm so fascinated with RTTY contesting but I ran my first one a couple years ago using a simpler but similar setup and was hooked. As you may or may not know yesterday was NAQP RTTY.
