KPA500 Stopped working on 40

Hello,
Yesterday all was fine, and today the KPA500 will not transmit on 40m.
All other bands show normal operation and output. It is connected to a K3. Any thoughts before I open the covers?

73,
Rob W3OMW

Re: KPA500 Stopped working on 40

If you have the KAT3 in the K3, make sure you haven't accidentally changed
the output to the SO239 which DOESN'T have the KPA500 attached. Changed by
tapping the ANT button. That setting is remembered by band. So if you
accidentally tap it, it's moved to the other SO239 on the back of K3, and
stays that way. Check anything that is remembered by band, including power
level settings.

73, Guy.

Thanks Gary! Ant 2 was selected for 40m. Ant 2 is my dummy load which I may have selected during the testing of the new Windom antenna. All is well with the ether now. *G*

Likewise make sure the K3 output power for 40 meters, for the KPA if you have the per-band power set, has not been somehow set to zero.
