26.485 data signal
« on: May 07, 2013, 2100 UTC »
I hear it (26485) when the band is open, especially to Mexico/Latin America.  Only in LSB and CW mode.  There's similar activity around 27.650 MHz. 

27.650 is almost always there.  Was wondering if anybody else on the east coast of the U.S. (or anywhere really) could also hear these signals.

I'm interested in what military/government use of the 25-28 is still in existence, even the proliferation of export radios to the point of every 5-10 kHz from 26.5 to 28 has signals on it during a good band opening.

There was a crapload of 27.5-28 MHz digital voice modes during the Vancouver Olympics up here in BC... our govts. still uses them. Don't know what department though.

There were several unmarked buses with no (or blacked out) windows in my neighbourhood with US Govt. plates one time the wide band signals pinned my E5 to the wall :o

Peace!

Could it have been some sort of jamming system? 

I could see IEDs and other remote-control bombs using the 26-28 MHz band, considering how many R/C frequency allocations there are there (and in the 29MHz, 30MHz, 31MHz, 35MHz and other "high-HF" and "low-VHF" bands).

Comms monitoring maybe? One bus must've had a hundred antennas on it from planar cm bands to bigass HF whips.

Peace!
