Hello,

Am getting back into the monitoring and listening hobby after many, many years.
In my 70's now, so please bear with me a bit.

I realize that many things have probably changed, besides the frequencies.

If anyone might please take a few minutes and help me clean up my database(s), along
with some pretty dumb questions, would be most appreciative.

It's the modes used, and any general name changes that I have the most trouble with.

a. Is Huntress still called Huntress, or does it go by the name of NORAD now ? Or,...?
b. What is USAF HF - GCS ?
c. What is LDOC (is it Arinc ? LDOC name still used ?)
d. In general, what Civil Aero.uses USB ? What MIL Aero. uses USB ?

e. The Coast Guard frequency modes are really confusing for me.
What modes do their ships use ?
Their Aero ?
Their S&R activities ?

Are these modes correct for my aero frequencies:

USAF HF - GCS USB
LDOC USB
HF - GCS USB
Navy Giant Killer USB

Unicom AM
ATIS AM
MWARA AM
ARTCC (Turin, e.g.) AM
Gander - Low AM
Gander - High AM

Huntress AM
Norad Guard (496.7 AM
Norad (267.0) AM
Norad Huntress AM
Norad AM
Air Refueling AM
Civil Air Patrol AM
MIL Air (various) AM
103rd Tactical (141.9) AM
104th FIW AM

Thank you very much.
Really appreciate it.

Let's see here...

a. Huntress is the tac callsign for NORAD, and is still very much alive;
b. Although the sites and freqs have changed somewhat, you can read the HF GCS article in our wiki and get a pretty good understanding of what it means...

USAF High Frequency Global Communications System - The RadioReference Wiki

c. LDOC = Long Distance Operational Control - a HF based network that aircraft use to communicate with companies when out of range of the usual VHF company freqs. I understand that most LDOCs have been superceded by more reliable satellite links, and the use of HFDL (HF Datalink) which is often misnamed 'HF ACARS', but once in a while you will see them reported

HFDL - The RadioReference Wiki

d. In most cases, aero (both civ and mil) use USB - however there are many ALE networks that have been noted using LSB.

ALE - The RadioReference Wiki

e. USCG ships, when using HF, are in USB, and many have been noted using ALE as well. I've also heard helos using HF, and there have been many reports of them using the standard VHF marine channels and the 4 UHF channels from time to time...the new LMR freqs are also discussed here...

United States Coast Guard - The RadioReference Wiki

f. Your mode list is mostly correct; however MWARAs often use USB on HF, Gander also uses USB on HF (however on freqs above 30 mhz, AM would be the general rule). Milair is generally AM; however it's not so uncommon to have a few flights using FM freqs on the ground to communicate with flight crews and so forth. The CAP folks are slowly migrating to P25 and narrowband;

Civil Air Patrol - The RadioReference Wiki

Also keep in mind that many bases are now moving to 380 mhz FM P25 (in many cases) trunk systems, and there are still many 'holes' where air-air (in AM) is often heard. It's wisest to consider this part of the band 'shared' .

g. For more information on groups local to you, I'd check the milair threads (and wiki) over on Scan New England.

It's a crappy afternoon weather wise - go get youself a tall glass of your favorite hot beveridge and start reading
