...but there's no lfunderground.com  :)

I hear these (digital?) chirps 24 hours, about the same strength, down below the AM broadcast band and wonder if anyone here knows what they might be.  Recording was made with the R8 tuned to 0.282 MHz, USB:


Best 73s,


Update:  Well whatever it is, if it's calling someone/-thing then I think the calls are coming from inside the house.. My Sony ICF-SW7600 tunes that low and I should be able to locate the chirp-er walking around with it.  Nothing I've unplugged so far stops it though. Still looking...
