I have not been able to get ptt to work with the ts-570s using wsjtx or flrig. I have tried suggestions like using c-media-A, ptt, vox, serial port set to use rts for ptt. There are even examples of people saying they use the CAT com port with rts using the same comport for PTT. I have read that pin 9 of the serial port is used to key the rig but I shouldnt need to mode the cable I purchased from digirig to work with the ts-570s.

Some suggestions are correct but not pertaining to the model of the interface you purchased. For accurate information please refer to the setup tutorial for Digirig Mobile at:

For additional troubleshooting of PTT functionality, please refer to this video:

# [CAT control not responsive on TS-570D](https://forum.digirig.net/t/cat-control-not-responsive-on-ts-570d/4092)I did try those suggestions. I broke down after days of fighting this and ordered CAT cable that is supposed to work. I’ll know soon.

Charles, ok I hope it works out. I set the baud to 57600. It seemed any lower settings the CNTL indicator would go out and there would be no rig control. look at my screen shot in the message chain for my settings. I suspect a “race” condition since there are no handshake control lines used with the Digirig interface. The higher the speed seems to work consistently. Good luck
