They might have toned down the earlier 775's. Some meters also do not really
read short peaks well.
What meter do you use?

A new habit, imported from CB, is people now turn the little power limit
pots inside radios up. A local contestor brings his 1000MP's over for work,
and I find the pots set for 50% more power than factory. He drives SB220's,
which are not even designed to run 1500 watts output, to more than 1500
watts.
If I set a radio back to 100 watts, the next time I see it it is back at
150w. He can't figure out how the pots get turned up, so he says.
A good number of rigs I see have the power pots cranked now, and the problem
appears to be increasing.

You can use the high-current enclosed miniature relays, but you have to
select a relay that does not have the armature common electrically with the
moving contact.
Ameritron now uses small relays on a PC board. If you mechanically float the
board, the relays are pretty quiet. The output relay they use handle 8-10 kW
reliably into a matched load, as long as it is not hot switched.
