Well I found the problem! I had the switch on my desk mic pushed in. I let it out and all works as advertised now. Talk about chasing a goose! Apologies for my rant.

Subject: Resetting the TS590

> Hello list,

> For the life of me I don't know what I did to my TS590SG, but I can no longer do direct frequency entry (the enter button gives the low tone), and wen I press and hold the antenna tuner button, the transmitter is on continuously, and I have to turn the radio off to stop it. The send button has no effect, even on CW with the keyer disconnected.

> So I tried resetting the radio from the keyboard, and that doesn't work either.

> I managed to get the control software talking to the radio and did a full reset that way. But the radio's behavior hasn't changed.
