Rtty interfaces

If you want to get started really fast, for no costs what-so-ever, just do the following. Having said that, once you get started with the digital modes, you will not likely stop there, and there is a great deal more to explore. If all you want is RTTY, a simple isolation interface and some decent sound card software is all you need. While I do not currently own one of the SCS modems, I will likely purchase one in the near future as they pretty much represent the pinnacle of digital operation.

but it will even handle PSK31, and offers advanced DSP to maintain contacts in the worst conditions (check the reviews on ). Not only can you work RTTY, AMTOR (ARQ/FEC), PACTOR 1/2/3 (ARQ/FEC), CW, etc. If money is no object, and I will get hate mail for this, check These modems are the top of the line for digital work. I currently own a KAM+ and it performs well despite being 10+years old. If you want to go the TNC route, check E-Bay for listings on the KAM, KAM+, and I believe there is an MFJ interface but forget the model number. Many of which are overpriced for what they do, in my humble opinion. There are quite a few others, Rigblaster, etc.
RTTY INTERFACES SERIAL
Signalink makes a great interface which eliminates the need for a serial port (I own one and love it, automatically keys the radio upon input), plus you can use PSK31, MFSK 16, etc. You may see examples on the web of the Hamcomm style interface (I actually still have one of the modems, the BP-2M), but I would not recommend this as the software is DOS based (nothing wrong with DOS) and would require direct access to the serial port, which you don't have. It's fairly easy, but you would likely have to use VOX since you only have a USB port.
