If I'm reading the manual right, the TS-2000 can do either true FSK or AFSK depending on what you have driving the transceiver and what pin you use on the 13 pin ACC2 connector. For example, the FSK output from my DSP-2232 can go to pin 2, or I can put audio to pin 11 and do AFSK Is that right? Dave Reinhart wa6ilt at amsat.org
