[Scan-DC] Pasadena PD encrypts but promises media access

For many, many years I've been using my scanners to listen to military 
air traffic along with local PD/FD traffic. However, with the advent of 
digital radios and scanners, along with encryption, the PD/FD listening 
is starting to get to be more trouble than it's worth. As a result, I 
have found myself migrating to almost strictly listening to military air 
traffic other than when some big event happens in the police/fire world 
of listening.

In addition to the ability to easily listen to this traffic with even 
the most basic scanner, it's also provides a lot of very interesting 
listening. It is all AM analog mode (and it's critical you have your 
scanner set to AM), there is no trunking and almost no encryption (other 
than very occasional uses when practicing classified type exercises). 
For those not familiar with the frequencies used, here's some very basic 
information:

While I could write a book on the subject, to give a quick and dirty 
overview, here's what you should know.....

1, Most fighters move through the Air Traffic Control (ATC) system using 
UHF freqs (225-400 mHz)
2. Most transport and tanker aircraft use VHF (118-136 mHz) for ATC
3. Bombers use both.
4. Both freq ranges are also used for tactical/operational use with the 
addition of the 138-144 mHz range for F-16/A-10 tactical use - and 
there's a lot of that due to the Andrews and Atlantic City F-16s and 
Martin State A-10s.

To get started, I would suggest you just start scanning those two freq 
ranges (138-144 and 225-400) and see what you come up with. Keep in mind 
that the military aircraft that use VHF for Air Traffic Control will 
also be mixed in with all the commercial air traffic in the 118-136 
range so it's more difficult to segregate them which is why I suggest 
starting with the freqs used almost exclusively by the military.

In the local area at Andrews we have F-16 fighters, KC-135 tankers and 
various Navy transports along with constant arrivals/departures of large 
transport aircraft and a variety of aircraft used for VIP flights - 
including the Presidential fleet of aircraft.
At Martin State Airport, we have A-10 ground attack aircraft and the 
C-27J light transport aircraft.
Patuxent Naval Air Station has aircraft of almost every type in the 
Navy's inventory.
Martinsburg WV has C-5 heavy transport aircraft as does Dover AFB DE 
along with C-17s
McGuire AFB NJ has C-17A transport and KC-135/KC-10 tanker aircraft
Then there are the fighters from Langley and Atlantic City
There is no shortage of military air listening opportunities in this 
general area.

For beginners, I would suggest checking out RadioReference.com, look for 
the Discussion Forums link, go to the Maryland page and check the 
"Sticky Thread for MilAir VII (2012). It will give you a good start for 
an explanation of the traffic and frequencies used for specific 
operations in this area. Other states have similar threads. The 
RadioReference database also contains frequency lists for specific 
military units.

Ease of listening, no expensive equipment necessary, a very basic 
omni-directional antenna will suffice and loads of enjoyment. Isn't that 
why most of us bought our scanners in the first place? Even your 20 year 
old scanners will work. Give it a try if you haven't already.
