Quick Question

[ScannerMan1989]

Hello! Not sure where to put this one so here goes... I have a freq I cannot identify... It is in the ISM range and it displays on my Whistler WS1040 as 912.0387500 and all it sounds like is popping and bzzzzzing. The popping and hissing kinda sounds like a record player. There are no patterns to the noises and have turned everything off in my apt that could be making the noise... Dunno if dude next door might have something that could do this.... I tried to listen in for a voice just in case someone spoke but nothing. It is NOT a squelch though. Google showed nothing! Totally stumped...

From page 68 of your manual.

Birdie Frequencies

Birdies are operating frequencies, which all scanners
have, that are created inside the scanner’s receiver and
can cause interference. If the interference is not severe,
adjusting the squelch might omit the birdie, but if you
program one of these frequencies after a search you will
hear only noise on that frequency.
To find birdies in your scanner:
1. Disconnecting the antenna.
2. Make sure that no other nearby radio or TV sets
are turned on near the scanner.
3. Press TUNE and then press PSE. The scanner will
search for frequencies and occasionally stop as if it
has found a signal. This is a birdie.
4. Make a list of all the birdies in your scanner for
future reference.
5. Press L/OUT to lock out the frequency for any
future searches after you have reconnected the
antenna.

Thanks for the quick cite. However when I move the scanner on any of the other birdie freqs it never stops and the squelch doesn't stop it BUT this 912 it DOES go out if I move in certain areas of the house....

Probably some source of interference within your home.

912 was and may still be the location of some wireless speakers and headphones. Keep listening and you may hear your neighbors playing music.

912MHZ is in the same band that has ISM and LSM stuff like power meters being read by your local electric company. Those signals are strong enough to break your squelch at 4 o'clock setting. Your dwelling may just have some. If in a apartment building expect a bunch of them. Popping and bzzzzzzing sure does sound like ISM.

Here is a visual of ISM pops and buzzing you're hearing on a waterfall
