338.9625
Over the last few weeks I've gotten a hit on close call with this frequency a handful of times. Always around the same time. I've googled but couldn't find anything. Also checked the ads-b sites but nothing shows up. Anyone know anything about it? There's no traffic just open air. It eventually...forums.radioreference.com
Guys,
Sorry to be such a pain. but I'm a newbie when it comes to the WBFM mux stuff.
1. What does it sound like when it's active?
2. Is there a fixed list of freqs or is it randomly generated?
3. Is any of the signal readable with normal scanners?
I might add that I'm "technically challenged" and never did get into demods, sidebands analyzers, etc.

For you NJ guys,
Have any of you plotted the VHF ARTCC freq sequence for WRI tankers leaving KWRI?
Was curious about the route to the south toward DE/MD and for those heading west over Philly out to Harrisburg area.
Answers to your questions
1 - open carrier if you have the frequency programed as FM
Somewhere here on the internet there was someone who was able to feed the UHF frequency from the radio into a HF radio and tune the conversations.
Unfortunately, I am probably going to have to wait until a few years from now when my day job does not interfere with the hobby. Gives me something to look forward to.
I am not technically inclined either - I just experiment when I can and if it does not work out - I just go back to knitting blankets...I mean listening to the regular stuff.

From this morning TEAM 11 flight off McGuire for AR777 (over the Atlantic). I know not South or West but I have to start somewhere.
1330Z 86-0028 85-0027 KC10s
126.475 McGuire radar
128.300 New York Center
133.500 New York Center (Oceanic)
the one aircraft had issues on the UHF radio so while they tried to use 268.025 Interplane - they decided to stay with 139.875 VHF Interplane.
Even after going to AR777 primary 315.900 - they decided to stick with the VHF channel.

Speaking of air phones whatever happened to phone patches on the various CP freqs around here.
Been some years since aircraft like a C-130 on way home to Arkansas would ask McGuire or Dover for PP
to their own landline Home CP.
They would give them a eta estimate and req certain things and a heads up etc then over and out..
Guess gone out with the rotary phones![]()

Terry,
Mark,
Your right. It's been a long time since I heard a VHF/UHF phone patch. Used to hear them all the time.
Same thing with the weather freqs. Used to hear McGuire & Dover wx all the time. Haven't heard them in a long time. I guess they get their wx from computers now?
Yeah Terry used to have link to website on that old WBFM Air/Ground coms system. Your right there was a Ham with
good waterfall radio and narrow freq filters who could discern some voice coms on the sidebands. Most times there is no actual
voice coms, Just something they turn on at times when up and about. Today with Satcoms etc they almost really don't need or use this often.
Used to hear AF-1 departing for overseas on this system but think they have given that up.. BTW this is older Stateside Air/Ground system only. Overseas there is no such thing. Euro guys never heard it back in the day over there.
That 272.325 I had the other day from that E-4B was very wide band broadcast.. Could actually see signal from 272.100-272.450 on meter.
May have actually been 272.350 as center freq.. This old system with 12 Nationwide towers or so was early Wideband Cell phone link system![]()
Terry,
My first reply got screwed up.
I'll put 128.3 & 133.5 in my scanner but I'm probably too far away to hear them.
TerryI would not put 128.300 in the scan. During normal times it is too busy with non-military traffic. 133.500 is a good one however. At home in PA - it was very monitorable and when conditions were good I could even hear the ground site. That would be approximately 60 air miles to the ground site.
