[Alinco] ALR22T Schematic

[Ray Keefe]

Does anyone have the schematic for the ALR22T? Or has anyone figured out =
what causes the reciever to get brain dead on occasion?

By that I mean it's sensitivity drops from a full scale reading to =
barely above the noise floor static. It's not antenna, or loose =
connections in the coax. SWR meter in line at all times, no fluctuations =
on xmt. Only receive. Not related to micrphone, different mikes. =
Different antenna's and feeds. Sometimes it comes back by hitting the =
xmt key, but this is not a relay radio.

Really frustrating when I have to tell a local who normally comes in =
full strength on 52 simplex on 10 watts, that he now has to up it to 100 =
watts because I can't hear him anymore. It's on all signals not just =
his.

Any ideas?  Alinco is no help, they don't respond to emails.
