I have a PA6-1BE-RXRFPS amplifier that was factory tuned to 451-465 MHz and I need to re-tune the amplifier to 443 MHz. After following the re-tuning directions in the manual, I am only able to get 80 watts out with 10 watts in. However; with 10 watts in between the factory tuned frequency range, I am able to get over 100 watts out. The schematics do not list any component changes that need to be made when re-tuning the amplifier. Does anyone have any experience with re-tuning these amps and/or component changes that should be made to tune these into the ham band?
Thanks, Pat
