[Scan-DC] Southern MD Audio Log Notes (05/25/04)

[Jeff]

Decent day. 2 tags and a few good suspicions leading to tags. 

386.95
Switched this freq over to FM mode. Definitely getting comms off of the PAX
Trunked system. One email I received today suggest that possibly this freq
is now in use as part of the New 380-400 MHz Land/Mobile allocation. This
freq is gonna take more work I guess but I know it is PAX related, no doubt
there. And it has just about has to be part of the Trunked System now as I
hear many different groups on the freq just like the Trunked System. Same
users just a new freq. I am going to keep playing with it in FM mode for a
few more days and see if I can catch the TRUNK CONTROL signal on the freq.
That should be the kicker. I'll have to watch and see what else the search
scanners pick up in the 380-400 MHz range pretty closely for a while. I am
pulling PL tones on it per my logs.

339.6
Brief, weak comms. Nothing gained

385.3
Very weak comms, nothing gained

238.175
Brief comms but used apparently as interplane during ACM. 

238.15
Had the Blues up using as Interplane. I must have flubbed up after the ADW
show after tagging this and forgot to lock it out. Done now.

275.5
Weak sporadic comms, could not get much out of it.

300.825
Used as interplane between apparent flight of 2. One was having some
problems but I could not get enough to discern what the problem was nor who
the users were.

390.95
Used as interplane at various times throughout the day. No Callsign heard
but I did hear them referencing direct JFK. Any of you folks up in the NY
area recognize this freq? I have nothing on it.

235.1
Unknown A/C reporting flight level to apparent ground Station.

283.35
Sounded like a PAX RTPS freq. TM talking to Aircraft apparently on the
ground. I will keep working it.

250.2
WATERBUG 294 with unknown station @ 16K with the flash.

244.0
Severely broken comms considering the location he stated put him square over
my house. Suspect Harmonic of 122.0

349.9
A/C reporting Troubleshooting complete, RTB. Did not catch a C/S.

252.8
Weak comms, nothing gained

337.0
Weak comms, nothing gained

141.1
Used as interplane for unknown A/C discussing vectors for landing. I could
not pull enough out to tell who/where. Have heard suspect "PAT" A/C using
this freq before/

349.8
A/C 303 calling GRAYHAWK Base. Good enough. Tagging as VAW-120 for now and
will work the details out later.  E-2C SQUADRON OPERATIONS It may very not
be used just by this squadron after considering the multiple references I
see referring to it as "E-2C SQUADRON OPERATIONS at Norfolk NAS" Possibly
used by all the E2-C outfits down there. VAW-10 works for me for the time
being as I associate GREYHAWK with VAW-120. Later I'll work the freq
alongside the other known freqs for the E2-Cs and should be able to better
pin down it's usage. I already have 349.85 as VAW-120 so this might just
have been bleed over. I it might be the other way around. But I suspect
349.8 is the good freq per references from others.

344.2
JV732 with unknown station.
