Model 674
The Hy-Gain series of CB radios
were a great line: Well made, not too flashy, and unique in style.
Of course, my favorite was the Hy-gain V, or Model 674 (the original,
as opposed to the Model "B"). As most of you fervored
fans already know, I'm a BIG fan of BIG radios, and so the Hy-gain
"box" series was always a particular favorite of mine
(Not too mention that BIG base station of theirs the 623).
Most of you are
familiar with the Hy-gain V in it's "B" version as pictured
below:
And many have
never seen the first Model 674, but once you do, you can't mistake
the differences:
The "A"
model is a bit different in the front, as it has two toggle switches
instead of the push buttons used in the "B" model. The
tips of the toggles light up!
The biggest difference
you will encounter will be on the back panel:
MODEL 674B
MODEL 674
See the difference?
The "A" model has a multi-pinned jack in the back which
is for the Optional Hy-gain VFO! Yes, the "A" model
had an accessory VFO (for reception only) which could be modified
for use on transmit as well.
As you can imagine...."Uncle
Charlie" didn't like that too much!
This combination
was VERY desirable to the freebander, and HAM Radio operator as
well - What better combo was suited for 10m conversion??
No matter where
you find the Hy-Gain V for sale (Garage sale, E-bay, swapmeet)
it will most likely be the "B" model. I've only run
across two "A's" in my time:
The first one
I owned and then this one!
There is a 3rd
model - the Hy-Gain V which looked similar but had a Uniden PCB
inside instead of the Cybernet chassis. It also had the usual
small-sized mobile meter vs. the large meter of the previous 2
models.

Model 674b - CBSAMS

Hy-Gain V - CBSAMS
291
The cybernet models
worked just fine, but are limited because of their 23channels,
and an inferior noise blanker for auto use. The Uniden made model
has the better noise blanker and like any early Uniden PLL chassis
- is easy to modify. I've run the Hy-Gain V in the WoodyWorld
Test van with great results, and for the most part, prefer the
large radio (I just wish they had kept the large meter from the
Cybernet models). The flat black finish with dull chrome, make
for a good non-reflective mobile!
