This was wierd. I have a Ham Gadgets Master Keyer 1 that seems to be a bit susceptable to RFI (not an issue for this list). Last night I decided to work PSK31 on 40m. My setup with Fldigi uses the rig control command to key and unkey the radio, no hardware PTT is used. The only connections to the K3 were the MK1 to the Key jack and a single lever paddle to the Paddle jack as well as the Line In/Out to the computer and desk mic to the front panel as well as the serial cable to the PC jack.
The problem was that when the PSK transmission ended the K3 stayed in TX. As I had experienced RFI on 160m CW from the MK1 before that kept the TX keyed, I uplugged it first and thereafter did not experience the problem with PTT remaining on. I'll need to resolve the MK1's issue separately. Here is my question about the K3, it seems to me that when in DATA A mode that the state of the KEY jack should be ignored. Even if KEY has a closure, it should not impact PTT in DATA A or SSB modes, or am I mistaken. 73, de Nate >> -- "The optimist proclaims that we live in the best of all possible worlds.
