What??? 10W - 1000W is 20db. Distance doubles every 6db - do the math...

6db is for voltage and current NOT for power .... do the research

There are plenty of decent used linear amps out there if you want to go
that route, but if you think about it in dB, 1000W isn't _that_ much
more than 10W.

Only a few S-units at the receiver.

Talking about "S-units" in such a discussion is meaningless *unless* one
has checked the calibration of one's meter - AND states the calibration
characteristics to qualify the readings.

The reason is there is no "universal definition or standard" of "S units".
There have been proposals - but so far no standards. The proposal that
seemed to have had the best chance was made in the 40's - and that was
where S9 = 50uv (at the antenna connector) - and each "S unit" down
being -6db. As noted - that never became a standard - in fact today most
modern receivers seem to be around 5db per S unit The reason seems to be
that using -5db/S results in S0 below 50uv being right around the noise
floor of most rigs - i.e. .2uv (S+N/N=10db).

But unless one states what specific characteristics of "S units" they are
using - talking about "S units" is meaningless (i.e. a "few" "S units"
could be 3db - they could be 18db - or more -- who knows if it's not
stated).
