I love Ranger! I had a few of the 2950/70 variations, and Ranger was
my favorite back before I discovered mainstream Ham gear. Hopefully,
you're working toward getting that type of equipment! :-) I still
have a soft spot for Ranger, and browse their catalog from time to
time.

I have a Ranger 2950 which goes from 26 to 32MHz. Its excellent in the

fact
that if theres not a lot of DX or local stations on i can scoot upto

31MHz
and evesdrop on the cordless phones )..You cant do that on a cobra or
Lincoln... well not without some severe adapting anyhows... a very
underrated rig in my opinion as they never fetch as much as Lincolns on

eBay
but have a much better coverage.

I have a 2970, it has push pull output to 150W, for the rest freq range is

the
same as 2950, best one I ever had, lots of DX.
Very stable too.
The 2970 has a big heatsink on the bottom side.
Have not seen people with one for sale here, all keepers :-)
I like the push buttons.


Lol yea lots of things to push. I would like the 2970 next but would need to
sell a few other things first. Are these variable wattage and what, if they
are, do they start from? Id hate to upset the neighbours with TVI )

Oh, it starts rather low, I'v measured lemme see:
just measured 3.3 A at about 13V with RF output at minimum in FM.
The set itself consumes about 400mA, so 2.9A = 13x2.9 = 37.7 W input to power
amp, so maybe about half that (15 to 18W) to antenna?
Add some SWR etc...
But maybe some more it is a nice class B symmetrical amp.
At full power in SSB it will peak 18A (says manual) but this meter only goes
to 10A, so have not checked.
Antenne wattmeter is kaput.. dunno what happend to it, dropped it or something.
18A at 13.6 = 244 W input for 150 out the effciency would be 61%.
So if it is really 61% at lower loads too you'd have 16W minimum in FM.
Seems I was close.
