hello
-
You both are talking two different amplifier - transmitter
combinations. Jeff is talking about amplifiers made
for the more advanced CB Operator, the Pride DX-300
being one I've mentioned before here on amps. Rich
is referring to Collins Equipment.
-
Jeff is right, the DX-300 will output about 310 watts
with 4 watts drive, so will my equivalent six meter
version of which I built for my old Icom 551 (10 watt
version). It's not that clean on the air...
-
The problem is it's linearity is very poor, I've measured
the factory design and it's less than 30dB down on my
new HP. I have one and have spent mucho time with
the circuit to clean it up.
-
The CB KW-1 amplifier is even worse, I measured crap
less than 23 dB down on one some time back. Nothing
short of a complete circuit rework will clean it up.
-
The Collins KW-1 is a sweet animal, often seen on Ebay
for much more than it's worth. One close by me was up
for an $18,000 starting price about two weeks ago. Yep,
you read the price right.

:Try the Pride DX-300 or KW-1.
:The KW-1 does not use 4cx250Bs
: Your sadly mistaken, Rich.
: The DX300 uses a tuned input for each band, and is
: rated for full power at c. 4 watts input.
: The KW-1 uses a swamped grid input, and is rated for
: c. 100 watts input.
: Both use the 4cx250.
