Do you have an IC-7300, and want to do RTTY using FSK with N1MM and MMTTY and/or 2Tone? Here are 2 guides on how to set it all up.

So did I ! (see my QRZ page or https://drive.google.com/file/d/1tZW57EhZfZ3eqNkW7Pk9gK9_M1XhhIoo/view?usp=drive_link).

I see these differences between David's setup and mine:

The main difference... David's approach requires two interface cables, one of which is not a standard USB cable. My setup uses a single standard USB cable (for full rig control, FSK, spectrum display, etc.)
David's document is very detailed and clearly written, and it is 31 pages. I am not as detailed, but I still needed ten pages.
My setup requires one additional software app (VSPE), which can be used for free, although the author asks for payment.
David uses EXTFSK64, where I use the 32-bit version, EXTFSK, which has worked FB on a Win 11 Home Ed 64-bit PC.
David covers adding 2Tone, which I did not document. However, it's easy to do, and I recommend doing this because 2Tone often seems to decode better for me compared to MMTTY. David also set 2Tone to play through computer speakers. I choose to use the radio's monitor option.

The use of VSPE to eliminate the need for a second interface cable is not new. For me, it has worked very well and seems to be as reliable as I would expect a setup using a dedicated FSK cable would be. But YMMV. So with these two different ways to do things people can choose which they prefer.

Thanks for sharing... 73

PS, David might want to publish that as a PDF so that no one can add a virus to the Word document and redistribute it. Recent versions of MS Word are better at protecting from embedded malware, but some people are still susceptible.
