I would check the band crystal for 40 m, and band specific tuned circuits.

I thought might be band switch move that around, move all controls does not come back. I switch to 20 meters all is good. I have not checked any tubes, which is a next step and have not really dug into it. I wanted to see if someone had this problem and can point me in the right direction before I go further. If I shut the radio down and next day turn it back on 40 is good again. I had the cover off for a few days while I was cleaning and replacing the blue filters and it seems 40 held up. maybe a cap problem or heating? Thanks to all Phil KM4OP _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
