Folks,
We need your help. As of 5:50am (local) there is a signal (Sounds
like a nice clean full quieting dead carrier. This is from
Fayetteville,GA with the remote antenna up at 125') on 449.675. This
just happens to be the input to the hub repeater for the Georgia
Skywarn Linked Repeater
Dennis,
Originally, we thought that as well, but we set the squelch up quite a bit
and the problem persisted. We did manage to 'solve' the problem by setting
the squelch very tight (about 2/3 of the way through its rotation, and the
noise level is about 1/3 of the way through the rotation).
I receive the signal here in Union City mid scale on the tall antenna.
Verified it is transmitting a 100 Hz tone also.

Good morning all,
We sell the Maggiore and when you team it
up with an Arcom 210 controller you can't
beat the audio. They work very well from
what I have seen. We never get them back
for repair. This is bad for us as we have a
repair business. Maggiore has a nice web
site you can go visit
We have used the ARR PD receiver power
dividers (PD-2 and PD-4) they work well
for us on projects. The price is not bad at
all.
