Like you posted.

Thinking a bit more the things involved in Rx but not Tx are the band pass filter components L401 and it's associated capacitors and the trifilar transformer T401.

The sweeps in the diagnostics are useful to check, if they are all giving a low max value that's an indication of a lack of connection.? Check the soldering of the toroids, everywhere, it's very easy to fail to get the enamel off.? I had this and redoing the soldering fixed it.
