Hi To All & Hope everybody had a good Christmas,
While the subject was brought up, I have been having a similar
experience here at my location.
It is not on a repeater, but a simplex radio (vertex VX3000l mobile)
for a base on the natl Red Cross freq of 47 mhz.
In the daytime the receiver is quiet and hears fine.
It seems as about the time the sun starts going down, the receiver's
squelch opens and has a constant static noise for many hours but
still receives fine.
It may do it all night, I don't know, I haven't stayed up to see,
just leave the radio on and go to bed.
Was wondering if could be power line noise (but why wouldn't do in
daytime also)?
Is there any interference to the HF bands like this at night?
Thanks,
Mike KB5FLX
An old trick - if the on-time changes about 6 minutes a day then it's
light-dependent (i..e a photo-electric triggered yard light).
In your shoes I'd power the radio from a gell-cell,
and then go flip breakers off one at a time.
That will tell you if the noise source is inside
the house, and if so, on which breaker.
