With propagation jamming both with F2 and summer "E" skip, you'd think that someone would be using the forgotten 11M International Broadcast Band, 25.670MHz - 26.100MHz. Just 5W and a retuned CB antenna can work wonders on that band. CB Outbanders are kind of dull to listen too, after a while. That band could be done well via mobile as well. Passing thoughts???

I have thought about this and it might work very well. The problem though is that in the USA, demonstrating the FCC’s great ability to allocate spectrum, it is allocated both as a broadcast band and a Studio to Transmitter Link band. While the only broadcast station I am aware of in the band is World Music Radio in Denmark, there are STL’s from the USA that you would not want to interfere with. However, as you say it would be easily possible to operate mobile. You could pre-record your program and put it on the air while driving around. Good luck locating a broadcast from a moving vehicle. It would make locating your station nearly impossible, which would be very useful. I don’t know if a CB would have a good enough frequency response for music, but it might if you feed the audio directly into it.

Aha! I was just about to start my post with "I'm probably gonna display my ignorance more than anything else..." blah blah
then me eye caught ThaDood mention "E" skip". I subscribe to spaceweather.com & whenever sunspot activity suddenly comes to the fore I usually listen to CB chit chat. Guaranteed interesting listening...@ least for a while. So if Pirates began occasionally experimenting (they can report their future times/frequ.'s on hfu) they will almost certainly be receiving new qsl requests.
-
I've tuned in the 11 meter CB and outband several evenings and afternoons and have heard nothing but static.
I don't think the sunspots are cooperating for pirates being that high up, although when the cycle kicks in in a year or two, I'm sure it would hold promise, as most SWBC bands are close to el-deado when compared to 2012 or 2002.
-
The State I live in used to use a frequency up there for STL for public radio. However, since the international broadcasters have faded away, I rarely tune around up there.
-
At last count there were three STLs left up around 26 MHz, but that was a few years ago. I am not sure when any were most recently logged.

Uh-huh... That's what I'm getting at, a pretty much wide, open, little used, International Shortwave Band. So, when the opportunity presents itself, propagation-wise, may pirates go nuts! Past hint-hint... The FREQ 26.015MHz has been tried and heard. Why that FREQ? Nothing found listed there, or heard, and CB Outbanders have a better chance of tuning there, on a 5kHz FREQ, than an even 000kHz FREQ. And, it was my understanding that some actually did, 20-some years ago. So, you'll just never know.
-
Obviously, it would be an OK spectrum for pirates once prop picks up. I haven't heard much, as noted before. Even channel 38, the SSB standby, has been pretty spare.
Now and then some outband activity, but not much.
-
Heck, the 11M BC Band would even be decent for local coverage, is CB walkies-talkies proved anything. A 1 channel, 100mW, CB HT covered a whole small town and a pretty large camp site. Then, when skip does happen, thar´ ya go. Just sayin´, let us have that spectrum, where every other government, or some other type of organized entity, seems to be abandoning that.

Make it the international lot lizard band and watch things pick up. "Thees is Fatima in Ankara looking for lonely truckers for good time."

As it turns out, way back in ancient history before many of you were born, someone was busted while operating HF mobile in motion. I don't have all the details and even if I did, I wouldn't repeat them without permission.
In any case, 11 meters (and 22 meters) would seem to be fertile ground.
-
A few months ago there was some pirate activity on 11 meters, I recall hearing a relay of an FM station, possibly some other transmissions as well.

In 1991 (I believe), a guy was relaying Voice of Laryngitis programs on 15050 kHz (I think) while driving through the Midwest. This was a clear freq that was occasionally used by pirates (in other words, he wasn't QRMing the USAF and this wasn't a primary pirate freq, like 6925 is now). But they set up a roadblock on I-70 and busted him near Denver.

Back when propagation was better I'd occasionally hear CB savages playing piratical programming on the CB bands. Ditto 20m and 75-80m. Haven't heard that for awhile.
Beware... the CB band is fraught with peril. Avoid Candy Cane.

Oh, very good.
Most of the details agree with my recollection but I seem to remember it being several years before 1991 because of where I was and what I was doing when I heard about it, but I will leave the details up to Andrew.
In any case, it demonstrates the "long arms" they had in those days and that they can find you even if you are moving, if they really want to. They are likely too overstretched with priorities elsewhere these days though.
-
I agree totally with Charlie. If they have the interest, they can go after you. I think the highways would be more dangerous because most have some cameras posted now. I've also read about boxes along highways that can read IDs of Bluetooth devices. Again, it all comes down to their interest & funding.
BTW, I looked it up & the raid was on October 7, 1991, near Limon, CO. Station was using 1 kW. Really wish I'd heard it, but in the days before the Internet, if you forgot for a day to tune around one of the lesser-used bands, you couldn't hop up on HF Underground to see what you'd been missing.

Yes, 1 kW. OK on the date. I guess that part of my memory of it became a bit skewed.

You'd wait for the next issue of whatever publication or newsletter you were a subscriber of to arrive in the mail.
