What about the "Freeband"?

Recently, I was banned from a well-known CB radio site when I responded to assertions that some agencies DO use the HF areas above 20 MHZ. I was civil, I was polite and I only presented facts I know to be true as I am a member of one of the volunteer agencies that uses those frequencies. But after presenting FACTS (and other members of that forum have been banned there as well for so much as the slightest, but friendly, disagreement with that forums views on the subject).

Before we continue, let's not let THIS thread become a flame-fest nor a heated discussion pro or con of the practice of "freebanding". This simply is to give you something to visit and, perhaps, listen to on your general coverage receivers, that's ALL. Yet, at the same time, it shows that certain military and quasi-military agencies DO use their HF resources.

As I said, the subject of "freebanding' came up and I responded to it, disagreeing politely and listing the reasons why I would not want it done. A person whom, out of courtesy I will not reveal, replied that he was a member of the USAF, flew as a crew member of C-130's, attacked my referral to OPSEC (Operational Security) issues, questioned how or why I would know anything about such a thing, etc, THEN went on to say that, "The Air Force does not USE HF at all, only VHF/UHF" and I, in effect, should go pound sand, etc, etc".
Before I could refute his assertions, I was banned from the site so I could not even READ any additional comments! IMHO, that is an often too typical reaction to any rebuttal of long-held beliefs of a moderator or owner of a site. What it SAYS, by such banning is, ''THIS FELLOW IS RIGHT AND IS GETTING TOO CLOSE TO THE TRUTH, SO WE BETTER SHUT HIM BEFORE SOMEBODY BELIEVES HIM!!!" :D They even fixed it so I couldn't even READ the site! LOL! Musta "skeered" 'em pretty bad!!!

In fact, it is the poster who alleges that "the Air Force doesn't use HF" that is completely devoid of knowledge of the subject!
:D

So since I can't post the info I was going to post over there, I will post it here with the owners' permission so that you may freely read WHAT USAF uses or doesn't use. It is on the web so I can only surmise that they don't care if the info is posted: it was recently when I went and looked at it.

I am referring to USAF's Global HF Network called "Mainsail". I will not publish frequencies here, but if the info is still on the 'web, and you are interested, you can Google the info and tune in. Google "USAF Mainsail" which we have discussed here before.

The point is, despite the desperately held beliefs of some of us, the military DOES use HF and will continue to do so. Mainsail puts the lie to attacks and false assertions of people who don't know what they are talking about! USAF (and the other services) DO use HF! I find it absolutely amazing how people come into a forum knowing not one dadgum thing about other people and make--for lack of a better word-- DUMB statements when they don't know WHAT the other posters may or may not know! :D The other guy might be a multi-engine, commercial, jet-rated pilot, yet here's some fella lambasting an opponent whom he has not a clue about! He might be a GROL holder, an FCC engineer. But some clown can make statements that are just so-----well, I don't know what to call it! :roll:

WHY would the military and government use HF? Because they still need long-ranged comms, and 2) UHF/VHF/computer networks use fixed plant such as repeaters and phone networks. If an enemy wants to take down communications, an important infrastructural element, he can take out a few links in the chain, and the VHF becomes useless! Many of the
high command elements, both mobile and fixed, STILL use TUBE-TYPE Collins and Harris radios to keep EMP from destroying transistor-based radios during a nuclear strike! Did you know that? And to maintain effective HF communications, we NEED a wide range of HF frequencies so if the MUF (maximum usable frequency) is at certain level at a given time,
vital traffic can still be passed. IOW, if 7 MEGS is in the tank, 26 might handle the traffic, and it is why they use protocols such as ALE (automatic link establishment) to handle traffic; it's so if things fall apart quickly, they can still pass traffic and muster resources. It's also why those "freeband" frequencies are still listed. IOW, it doesn't MATTER IF, WHEN, or WHY they decide to use those frequencies, when they DO want 'em, they'll HAVE 'em!

Again, this is not a debate about freebanding, nor is it pro or con. It is simply truth and info we may be able to use. If you like to listen to shortwave, then you can perhaps listen into Mainsail. Be patient: military comms are NOT "fire in the wire, jabber, jabber, jabberjaw 24/7". You might hear 'em, you might not! It depends on the mission at the time. During 9/11 or other threats, it was/is high traffic levels. If things are "cool" 8) you might not hear 'em at all. Also listen to WWV, the time station on 2.5 5,10,15, 20 MHZ. This will tell you, generally, where the MUF is during your listening time, and give you a rough idea of what frequency to listen to.

Again, this was not meant to start a debate--I've been a "good" boy on here, and I present the info for your enjoyment, not to start a flamefest. If one starts, I'll quickly bow out!

cw, how dare you!!!!? (just kidding!)LOL


i enjoyed reading that. good info.
are you speaking of the CAP when you refer to the volunteer org.?

i am curious about a specific group of freqs. and what their usage is, and it seems like you are "in the know" about this subject.

who uses the freqs. from 27.415-27.505?
i know what goes on above and below that; i just dont know who the "official" users of those freqs. are.

thanks for any info you can offer,
loosecannon
 
There's a new CB forum that will ban you if you don't post enough !?? that's just plain weird !

And your right, ALL large aircraft that fly global use HF.
 
Don't forget, a bunch of the CB 'forums' are really nothing but astroturfing sites for vendors selling radios.

It's not good for business to discuss things that might discourage people from buying illegal radios or amps.
 
cw
folk here used to listen to those women "mainsail mainsail" with the narrow but very readable communications grade audio during the last 2 wars, it sure got the pulse going,
i also know the usaf over here used freqs around the 45mtr pirate band years ago,
even heared pilots ask people to stand by while they talked back to base,
you dont argue with a guy whos ride or his buddies ride may be a fully loaded f16 unless your a real dummy, when they talked everybody stood by and the pilots always thanked them after they were done, jolly nice chaps,:wink:
whoever thinks they never use hf for comms needs a better receiver.

Yes sir ....I believe you have certainly "hit the nail squarely on the head!"
 
Back in the 80's I spoke with a C-130 Supply plane carrying supplies to Sumalia during the war there. He was 10,000 feet up and 300 miles of the coast of Rhode Island. I came across him talking to someone else somewhere in the 27Mhz LSB area above 27.555 and decided to talk to him. We talked for atleast 10 minutes. One of my best contacts
 
good link ken :wink:
my rarest copy was talking to my buddy on a royal navy battleship on his way back from the gulf,
i aint admitting talking to any usaf pilots :lol:
 
hf

When I was a radio operator in the Air Force for 22 years, we used HF, on 5, 8, 11, 13, and 3 megs all the time no big secret, it was ssb<wow>.
The ARMY use to use a channel on CB to shout back and forth for training near Ft.Knox , Kentucky years ago.

The coast guard uses hf also , so no big deal...

doctor :shock:

It's my understanding that 27.410 to 27.540 MHz was once a "business band," long ago vacated by users migrating to other frequencies not populated by freebanders.

From the Frequency Allocations Chart URL provided by Ken White (thank you!), it shows that area with mixed land mobile, mobile, and fixed stations, non-government exclusive, i.e. no mil comm's. I guess it's just freebanders who reside there now?

I happened to run across this site not long ago when I Google'd "freeband radio": http://www.freebandradio.zoomshare.com/ that has some rather interesting information regarding freebanding in other areas than 11 meters. Verrrrrrry interesting...

After 9/11 the "Echo-Charlie" bands went almost silent.I have noticed in the past 2 years there has been more and more activity there. In the past two years, I have noiticed more American operators using the "Echo-Charlie" bands than in the twenty years I've monitored them.

I imagine that's probably due to what the guy at the above website observed:

"Once 11 meters became overcrowded and/or unusable due to solar activity or the lack thereof, astute freebanders soon decided that they weren’t constrained to 11 meters. By building simple dipole and similar antennas, they could operate on different freebands, close to existing Ham Radio bands, using the Yaesu FT-101 and the successive rigs in the 101 series, and other ham rigs as well. Often those rigs’ VFO’s would reach below the ham bands where freebanders could establish long distance communications. The 21, 45, and 85 meter bands were born."

Now with all the ham rigs that have the capability to be easily modified to transmit through the entire HF spectrum, I guess it didn't take long for people to realize they could string up a dipole and talk to their friends they couldn't hear any more on 11 meters. I remember someone saying they had been using the 6 MHz band for years whenever skip dropped out on 27 MHz.

I guess I'll have to do more listening on those other bands and see who's on. Is one band more active than the others?
