[FedCom] 418.75 Active Recently

[Tom Greenwood]

Just made some checks here from metro west Boston with the following
results:

418.625 10/S9 @ 130 degrees ETN	Azimuth and signal strength suggests Needham
Towers
418.875 S7 @ 120 degrees ETN		Most likely one of the lower high rises in
downtown Boston

All measurements conducted with an Icom R7000 and a Create LPDA at 75 feet.

Have just put the R7000 into auto memory mode.  Let's see what comes up over
the next 24 hours.

73's

Tom, N1JQB
Metro West Boston

And to add some confusion to this, this afternoon at approximately
16:00, here in the Boston area DEA channel 1 418.6250 started
broadcasting a trunking control channel as well as Channel 10 418.8750
(Weak signal at my location). other channels with a P-25 encrypted
signal this afternoon and evening are 414.4750. 418.9000 and 419.4250.
Very strange, further monitoring in the coming days is warranted. Is
this the start of a DEA trunking system? Is it just something screwy
going on.
I'd say that prior to this 90% of al DEA radio traffic in this area has
been P-25 encrypted.

That would be the DEA, of course, on their Channel 3, which is normally
conventional simplex. I've never run in to a repeater on DEA Channel 3
or 4
(418.675 MHz), but have run in to remote base station transmitters on
these
frequencies in rural areas.

Some DEA offices have started using P-25 on all their frequencies, but
many
areas continue to be analog.
