Roger and Group,
PSK31 was developed and named by English amateur radio operator Peter Martinez (call sign [1] G3PLX) and introduced to the wider amateur radio community in December 1998.
About the same time frame, Kenwood introduced the TS-2000. Which at the time was the most complete dual receiver multi-mode transceiver ever produced.
The designer of the TS-2000, seeing the usefulness of sound card modes like pSK-31 and later WSJTX added a second PTT input on the ACC Jack that turned off the front panel microphone input and enabled a rear panel sound card input also on the ACC Jack.
A sound card designer, Tigertronix / Signalink built a PTT output into their product triggered by the sound card audio. They took advantage of Kenwood's mike / aux audio selection by selecting the correct ACC pin to feed data PTT and data into the rear of the TS-2000.
Basically a plug-and-play solution for TS-2000 owners wanting to use PSK-31 and later on any other sound card program for RTTY or WSJTX.
IF a TS-2000 owner that is new to WSJTX wants to try FT8 or FT4, CAT control sounds like the "logical" way to send PTT to the TS-2000...... *Except* CAT control turns on the front panel microphone...... and defeats the expected rear panel audio input.
"I see the PTT light but no output power on my TS-2000."
is a typical response from new users when using CAT to control the PTT on the TS-2000.
My response : Don't use CAT.
