This is about one of the New Jersey MSF5000 stations. It has been on the
air for almost a week now, reconfigured as a conventional repeater...
Yesterday and today, I've had a chance to really give it a "shake down" and
I've noticed an issue that bothers me. I'm not sure what is causing this,
so I'm reaching out for suggestions/thoughts.
When I engage in a QSO on the machine for an extended period - like 10
minutes or more - I get an alarm right before the repeater drops. It is a
double beep, ("beep-beep") and it happens after each transmission. However,
if I allow the repeater to "rest" for even a short amount of time (like 1
minute or more) it "resets" - goes away.
I'm wondering if this is some sort of SWR alarm? The actual SWR read by my
Bird at the antenna connection on the station shows ~125W forward and ~1W
reflected. My feedline is approx. 50' (yes, only 50 feet) of 1/2" Heliax
into a Decibel 6dB omni antenna. Could it be because I'm using the
circulator originally installed in the machine - and obviously slightly
detuned for the frequency it is currently operating on - or is there some
other issue that may require my attention? Is anyone else experiencing
this?
Any ideas?
