Title: Marker? On 18.1025 MHz [EDITED]
Post by: alleycat on November 05, 2020, 2356 UTC
Narrowband marker? going "bippidy bippidy bippidy bippidy" nonstop for days (weeks?) with carrier center at 18.1025 MHz (listed as a W1AW frequency, but this signal doesn't sound like it's carrying data). Audio sample (USB mode tuned to about 18.102 MHz) at https://www.lutins.org/temp/181025.mp3 (https://www.lutins.org/temp/181025.mp3). Thanks for any help ID'ing & 73 de KC2KLC.

I just learned about KiwiSDR - checked some stations not far from me, and none of them are picking this up. SO - I have to suspect some type of local interference, which is a bit odd, because I'm in a semi-rural area, but there are a few other houses around...

Interesting find. May I ask the approximate location of the SDR that you used to dial this in?

I am located outside Binghamton, NY (south-central New York State - an hour north of Scranton, PA). I checked an online SDR further west in New York, and also one southeast of here in PA, and didn't hear it.

I just got out a portable shortwave radio - not picking anything up in the house. I a couple of miles outside town (as the crow flies), so I suppose it could be somewhat local ?
