The Pro model offers a variety of options for configuring radio control, PTT, CW and FSK when using both included serial ports. The Pro model has separate FSK and CW outputs. In order to change from CW to FSK, jumpers are changed inside in the unit or FSK can be set to key the DTR line by using MMTTYвЂ™s EXTFSK feature.

The Plus model outputs CW and FSK on the same jack though. The Plus and Pro models fully support FSK (and CW) operation and have a separate output for PTT in addition to PTT on the MIC connection. By using MMTTYвЂ™s EXTFSK feature, the CW line of the Plug & Play model can be used to key FSK by configuring EXTFSK to key DTR to FSK for the COM port assigned to the Plug & Play unit. The CW output is keyed using the DTR line of the USB-to-serial adapter. The Plug & Play has a built-in USB-to-serial adapter. The Plug & Play model also does not support FSK directly, but itвЂ™s not impossible. For details on adding FSK to a RigBlaster Nomic click here. Gert, K5WW, did build an FSK keying circuit inside his Nomic. PTT is connected to the radioвЂ™s mic input. The Nomic is for AFSK operation only by offering an audio interface between the sound card and transceiver for both transmit and receive. Both the Nomic and Plug & Play (plus the discontinued M8 model) do not support FSK keying directly (except the Plug & Play вЂ“ see next paragraph). The next model in line is the Plug & Play. The RIGblaster The RIGblaster is a very popular brand of sound card interface. I highly recommend microHAM products for RTTY. Their support and documentation are excellent.

Because there are a lot of different units available and because microHAM is constantly updating its line, its best to browse their site for more detailed information on their products. Even though it was a beta unit that was one of the very first built, it has NEVER failed me or even hiccupped вЂ“ ever. I currently own an original microHAM micro KEYER and still use it on my 2nd radio for RTTY contesting. MicroHAM or microHAM offers a very wide variety of interfaces that run RTTY and work with MMTTY.

For more specific information, refer to each manufacturerвЂ™s website. Some of the manufacturers and their products are included on this page. If you are using AFSK, they all should work. However, not all of them are capable of keying FSK. All of them should work with MMTTY and nearly all of them come with cables to interface to your transceiver (you must specify which cable you need). There are several commercial sound card interfaces available. If you choose not to build your own audio interface cables or FSK/PTT interfaces, you can buy a commercially built sound card interface.
