[Premium-Rx] Problem with RA6790/GM

[Damien Vale]

Hi all,

I have a RA6790/GM I've purchased, but the seller has said it can be 
returned if found to be faulty.

Initially I found it would only operate on AM, and also no bandwidths could 
be selected.  Running the BITE test I get faults 31 to 35 inclusive, 
indicating there is a problem with the filters. I've pulled each one out 
and cleaned the contacts and sockets, and also inserted & pulled each 
filter a few times so the friction helps to clean them also. However the 
faults persist.

Any suggestions as to a known problem, or is it one to return?
