Hi Folks!
We have a licensed freq of 48.74 and every spring and fall, our
FM radio picks up a weak signal in the morning. It goes on for hours.

Could it be VHF lo-band "skip" on a baby monitor?
Check to see if ten meters is open when you hear
it. If it is, it's likely something skipping in on lo-band.
Quite alot of fun back in the late 70's and early 80's.
I was hearing fire dispaches from New Mexico and
taxi companies in Jamaica from my home in Maryland
with an Grove outdoor omni antanna hooked up to my
scanner.

Firefighters in the next county also used to operate
on VHF Lo-Band for both dispach and fireground.
When the band was "open" they would often exchange
"radio checks" in the mid-morning once a week with 2
fire companies sharing the same frequency in the UP of Mich.
and another in Kansas! They even exchanged their
version of a QSL card in the form of uniform patches.

Yes, the good ole days of 1st generation VHF Lo-Band
radio was always alot of fun when the band was open!
