[Elecraft] Fwd: Has my KPA500 failed?

[vtnn43e at comcast.net]

I shorted the line to the amp and sure enough the * shows up. Hooked the line backup to the Flex and still no *. So something has gone wonky in the Flex. Thanks for the help!

Switched to 20 meters and hit tune again. Still 25 watts out and the band display stayed where it started which was 3.5. Powered down the rig and amp, powered both back up but still getting the same result. And there are no faults showing. Looked in the user manual but nothing there seems to apply.

Sounds like it's not getting keyed? This happened to someone else a 
few weeks ago, and he found that a cable had come loose ;)
