[B-R-I] UnID Ch.s 60-61?

[Ed Hennessy]

Those channels span 746-758 MHz.  This is a new public safety radio 
allocation that the FCC is beginning to assign.  It's for trunked radio 
systems with narrow deviation (6.25 kHz) and digital modulation.  I was not 
aware of any licenses (permanent or experimental) in this band in New 
England, but they are definitely coming on line elsewhere.  I suspect one of 
these systems is what you were hearing.

This is one of the results of the digital TV switchover; it's one of the 
uses for those 'out of core allocations' now that analog sunset has passed.

For the past few months I've noted a strange signal/static on Ch.s
60-61.  I figured it may be just some local interference, but the
other day I was up at the donation/thrift shop at Endicott Plaza in
Danvers and there was a couple of working, portable, analog TVs, so I
checked and——sure enough——Ch.s 60-61 had the same signal.
Could this be "Broadband over Power Lines" or some other "white space
spectrum" signal testing (it doesn't look like "MediaFLO" on Ch.55)?
