they were not built for continuous service. Apparently, at any load.
Shame, too. With modification, they can be a pretty decent supply.

Ah Ha then, maybe dear old former friend wasn't lying then about
modding them. He was always modding something when I was over at the
shop. *He sure wanted them back pretty bad. Tough. :-I


* *They're nice supplies. And as you pointed out, you DID work CB
off of one for a couple of years without issue. But that was
intermittent service, which is what most of these supplies are built
for.

* *Most any supply will work for most applications. It's continuous
draw that does them in. But that's not a surprise. ICOM's, like R71,
R7000, R7100 are renowned for running so damned hot that the back
panel can be too hot to touch. Even the factory recommends going in
periodically and touching up solder joints, checking components for
heat damage.

design.

Nothing awe inspiring Peter, it was part of six pieces I ran in my
"fun car."
148GTL (old version) with the slider and 50 watt final with the extra
channel kit . I have a homebrewed modulator box ( from a firefighter
friend) that I coupled with it when it was in the car. The mod box
wasn't really a linear ( though some may call it that) it wasn't
really to talk further miles wise - - but it really cleared up the
voice - almost like a speach processor if that makes sense. Ninety
nine percent of the time I would talk on sideband, I really enjoy
having the slider because I could tell a buddy to meet me at a
specific freq ( he has the same type of radio) - and it would be
absolutely crystal clear - crystal. At times I can talk all over the
world when the skip rolls, my funnest time was when I spoke to a
gentleman in Trinidad West Indies - in his accent he told me "Unit 67
- you're sounding like a local out here." Fun times.:-) I can just
imagine getting my ticket and actually legally be able to have a cup
of coffee with someone in Guam. I also have the 29LTD Classic - all
tricked out. Ha!


Antenna wise I have the Antron with the ground plane radials at the
bottom. I also have a big yagi antenna up there but it's not quite
setup the way I would like it - coax wise and not having a rotor at
the present. How can someone not love this entire hobby is beyond me.
I just wish the CB Newsgroup wasn't trashed like it is. You're a Ham I
would assume Peter?
