Re: Intermittent poor reception on VHF
Did you check your IF filters as I advise you previously? I added I link to assist you. They can cause several reception problems.? Regards.? Ct2gla A quinta, 26/11/2020, 23:37, PU5VEN <aldoir@...> escreveu:

Chinese TCXO Verification ?
¿ªÔÆÌåÓýThe previous thread brings up another question. How did/do you go about verifying that the TCXO is working properly and that it is actually better than without? I guess if it is not working properly it would be just like some of the rigs from the old days - chasing each other across the band.Mike / W8DN |

Re: PU5VEN: Your Chinese TCXO ?
