Hi Don & Rick,
I have been in contact with two different sources
for information regarding the ARX-2125 & 1225 model
amplifiers. I have some information inbound via
fax later today.
At this point, there is no service manual available
that I or any of the others experimenting with the
surplus Uniden ARX-2125 ACSB Trunking Amplifier
models.
Milcom is gone and Powerwave/Cresend don't have
or offer any help for these models. I along with
a few others have been in touch with one of the
former Milcom people (Roland) regarding some help
with these units.
Just off the phone, I will send some of the tech
info I've made up for these amplifiers to Roland
that he might be able to provide some information
back to me after we ID the model, which I will
happily share with the group.
I would like to ask that people reading the posts
on the Uniden prc group not continue to pester
Roland about this unit. Anything he supplies me
will be shared (for free).
Rick has done some work with the amplifier as
mentioned below... I have a similar 1225 unit in
operation, which easily blows 130 watts (clean)
output. I have bypased the driver hybrid for
higher drive (about 8 watts) input.
As mentioned by me before, you can also review
the n2chk web page for more information
After some information is exchanged, you can
have copies of what we turn up.
cheers,
skipp
