Re: uBitX reduced power option

 

Mark RV1 will adjust the drive power this can be remote mounted with use of a good shielded cable. RV2 and RV3 are bias control of the two IRF510's.

When I had a V4 I had adjusted it to 5w on the lowest bad (80m) so I could drive an amp as well as save the finals while doing full duty cycle modes.
