I recently acquired a Viking Ranger in nice working condx.

I am interested in using this on AM on 160, 80, and 40 mtrs. The Ranger
runs around 40 watts Am carrier output. I would like to get an amplifier
to use with this xmtr, maybe a vintage amp. What should I be looking
for? I would like to run legal Am Limit on these 3 bands. Should I
forget about Vintage Amps and get a modern Amp? Suggestions please. Any
pitfalls to using a modern Amp?

Thanx

Put the thing on the air as it is and have some fun.

You can add an amp if you want, but give it a try with 40W and see
how you do. I bet you'll be surprised.

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.

Uhhhhh yeah it is. 1000w to 10 w is 20db ...

Right, it's only 20 dB. That is far less than the day to day propagation
variations. Only 3 1/3 S-units. Not much at all.

But..... 20dB can make all the difference in the world in being
heard.... and not being heard.

That's BS! If what you have stated is true, no one would run more than 10
watts. Believe me, 20 dB is _very_ noticeable.

Sure, it's very noticeable. But, as someone running half a watt CW
these days, I can say that it's not everything.

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

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).

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

Ok so I mixed db and dbi, point for you. Now tell me that 1000W is
"almost" indistinguishable at the recieving end from 10W - and S-units
are a valid comparison standard...
