[RTTY] TinyFSK modem for 45 and 75 baud

[Jim W7RY]

The Nano that I'm looking at has different pin numbers for the functions 
listed on the page below. Is this a problem?

Looks like a cool little project for us FSK purists.

Thanks

It might be a nice project for those of you who are set up for logical keying but don't like the EXTFSK jitter, have wandering stop bits with your UARTs, or don't want to deal with MMTTY between your logging software and radio for whatever reason.  It's an afternoon project, if that.
