[ICOM] Amp tuning

[Bob Bennett]

I have an Icom 756 Pro III and just hooked it up to my old Detron 
GLA-1000 amp. I have two questions:

   1. The station has a g5r3 that the Icom automatic tuning feature has
      been tuning quite well. Now that I have the amp do I need to use
      another tuner between the amp and the antenna, or does the Icom
      tuner tune the G5RV through the amp. The SWR reading on the
      radio’s meter is showing an SWR between 1.0 and 1.5. The meter on
      the MFJ Versa Tuner (coax direct) in line after the amp is showing
      an SWR as hi as 3.0.
   2. When tuning my amps, I have been tuning them using FM. I have
      never been confident with hellllloooooo on ssb and my whistling
      skill is as bad as my singing. It this (FM tuning, not singing)
      harmful to the amp?
