[1000mp] Internal Tuner with Amp

[Dennis]

An added consideration if you use an internal tuner with an amp- 
definitely DON"T use it if you have a bandpass filter in line.
At the various multi-ops I've been at, we've popped several Dunestar 
bandpass filters that way.  The filters are set up using
50 ohms in and 50 ohms out- if you use the tuner and change that they 
don't like it.

As with any tuner, if it hasn't found a match in 20 seconds, turn it 
off.  For some loads, for some reasons, it won't find a
match.  Sometimes, if my tuner can't find a match, I put a dummy load on 
the output, find the match, and then try the tuner
again on the real antenna. 

On an 80M dipole cut for CW and I want to use it on SSB, my tuner hunted 
forever.  I went to the CW portion, matched the
antenna with the tuner, then worked my way up the band, matching the two 
every 50KHz or so.  I could then find a match
when I got to the SSB frequency I wanted.
