Noticed something new this weekend on the MP during
the 10m contest here ... first problem ever with this rig.

The HIGH SWR light started to come on, and the SWR 
LED's would indicate full scale ... output of course dropped.

Took the amp off line, still showed the problem ... pulled the 
bandpass filters off line, nope problem still there ...

Now, into the 50 ohm DL ... still shows the problem ... seems
to show ONLY on 12m and 10m ... output on the other bands 
transmit seem normal ... rcve seems normal also.

This is a late 1995 model, it has the factory mod for the common
15m RF problem ... no other problem to date with this rig.

Ideas ? I do have the service manual for reference ... so far
looks like something that is only in line for 10/12m, like a
low-pass or high-pass filter  perhaps ... ?

Anyone else seen this ? 

Thanks !
