[1000mp] FT-1000MP problem (Maybe with bandpass filter relays?)

[KB9GKC at aol.com]

Hello 1000mp users,

Here's the symptoms and settings:
on  160, 80 and 40 meters
SWR meter, both external and internal SWR meter  occasionally jumps to 3 or 
4:1 on resonant antenna
When this occurs I can  keep mike keyed and let the power output drop to zero 
and then talk and SWR is  still shows high.   A Quick un key and re key of 
transceiver and the  SWR is normal.  At first I thought it was a problem with 
either the tuner  or amp or dipole, all possibilities for problems in these 
areas have been  systematically eliminated.  And the symptom of Hi SWR is always 
cured by  unkeying and rekeying the transceiver.

My thoughts are that the  problem lies in the bandpass filter network, 
possibly with a relay that is  utilized on the three bands.  I have not yet looked 
at the schematic and  any input would be appreciated.

73 all,
Douglas  KB9GKC
