VHF power amplifier with low third armonic?



Hi all!

I have tried running some VHF power amplifiers over 100/150 Watios attached
to my TS-790 and all of them gave interference problems to receive the
downlink in UHF.

I even tried connecting a duplexer VHF/UHF in the p.a. output, in the arm of
UHF over a 50 ohmios load, and it reduced a bit the problem but it didn't
desapear completly.

If anybody is running a VHF power amplifier over 100/150 watios and you
don't have problems in your UHF reception, I would apreciate that you send
your experience and tricks to ea4cyq@amsat.org

Thank you very much
