very low RF output when using BPF.


 

Hi everyone,

knowing now that the yahoo X1M group no longer exists, the is my last resort. I bough the X1M back I'm 2014, I guess, due to busy life I only realised?
that my X1M was defective now in 2020.
I'll explain what's going on.
I get full power 6 watts out of the X1M when the BPFs for 10 15 20 40 80 bands are not engaged.?
out of the ham bands the radio is not designed, it works really well, very sensitive receiver and again 6 watts. I suspected the BPFs or one of them could be faulty, so I decided to bypass the BPFs. Things got worse, therefore I can assume it's not the BPF.
I've checked the the RX/TX relay and it's fine too.
I'm running out of ideas here. Does anyone know
what's going on with my X1m?

Thank you in advance

Flavio,

You might try re-installing the firmware, see the files section for various versions.?
