Hello: I have a TS-850s that is about 10 years old. I turned rig on and I tried to work the Florida QSO Party. When I pushed the PTT button it keys the rig but after I let go of the button it will not go back to receive. I tried the CW mode and it will not key the rig, only when I put VOX on. Any suggestions? Thank you. Paul Gondos, KA3JOI pgondos at hotmail.com
