Chris,
I think I will go for BPF bypass straight away. In this way I will confirm that this is were problem lies.
I located T401 input connection but I need to confirm <RX_IN> side. Do you mean C401-C402-C404 common point? I think there was typo in your previous post so I need be sure.
Can I shorten these two points or do I need to unsolder and disconnect T401 input side and connect to <RX_IN> using short jumper wire.
Thx.
