My question was crafted to try and understand the effect of Q on tank circuit
voltages, not how much power to run on 30M.
I should have been more careful in crafting my quesion.
Yes -- 200W fine, great, 10-4.

Thank you Carl:

OK.

Since 30 meters in not a IARU band, countries can only authorize its use
within it's own country, radiation outside of one's country is interference to
services outside of the amateur service.
So use by DX stations surprises me. from: en.wikipedia.org/wiki/30_meters
30 meter band plan IARU Region 1
License class 10.100-10.140 10.140-10.150
SSB may be used during emergencies involving the immediate safety of life and
property and only by stations actually involved in the handling of emergency
traffic.
The band segment 10.120 to 10.140 may only be used for SSB transmissions in the
area of Africa south of the equator during local daylight hours.

What good is getting that 3dB gain from his TL-922 going to do him?
(while burning an extra 400 Watts during key down)

I am much amazed and impressed!

keep it to yourself, at my age I just don't care anymore.
