Not really tricky, but some things to pay attention to.  These rigs
are putting out 100 watts when everything is set up right, so power
requirements aren't quite the same as with a 25 watt 2 meter rig.  We
might have already discussed this, but is your power cabling up to
snuff?  How big is it?

And how are you measuring the power out?  Some meters read high, some
read low, the metering in a typical HF rig can easily be out of
adjustment 30 watts or more.

I've already deleted the earlier messages about your setup, would you
mind giving us the rundown again, i.e. what type of coax, how long a
run, size of power wires, etc.?
