Al Fansome, Call your office

Shortwave Pirate broadcasting has been going on for years. While it is illegal to transmit radio signals without a license, it is not illegal to receive those signals. There is something sort of sneaky like you are hearing something you shouldn’t, part of some underground thing, listening to these guys. I am almost remiss to write something about it because I don’t want anyone to get into trouble.

Anyway, on any given day or night, pirate broadcasters roam the shortwave airwaves. Much of what they do is typical sophomoric humor, such as playing a song where the only lyrics are “god damn you” over and over again. Some of it can be somewhat entertaining. A lot of what they tell as jokes are inside baseball, you have to listen and do a little research to get it, the Al Fansome reference is one. There are no set times or frequencies. It is quite common to hear one guy tuning up and getting ready to go on the air when the current frequency occupant signs off (happens often on 6925 KHz).

Most of these guys build their own transmitters based on designs found on various websites. Power levels vary, but 10 to 50 watts is common. Because of this, a good low-noise receiving antenna is required to pull them out of the noise floor. I have used, with good success, a K9AY terminated loop antenna. We are in a rural area, so it is pretty low noise to begin with. Even so, the coverage with a 50-watt transmitter is remarkable when propagation conditions are good. Sound quality can be quite good for a homemade AM transmitter.

There is a lot of focus on FM pirates these days, that particular setup is likely the easiest to attain for most non-technical types. There are a few AM pirates floating about, those are likely the most difficult to construct and conceal once they are on the air. Both of those broadcast bands have the advantage that there are many kits and or instructions on how to build a pretty good-sounding transmitter. Shortwave seems to be a small cadre of dedicated hobbyists that simply like to fool around on the radio.

In any case, with the FCC stretched thin, it is unlikely that a SW pirate will be busted but not unheard of. One SW pirate station was busted in Florida about a month ago. Even so, that was the first one in almost five years.

For the most part, the activity seems to center between 6850 to 6970 KHz or so. Some others operate around 15055 to 15070 KHz. Here is a brief selection of what one might find on the SW pirate frequencies:

WHYP on 6925 USB “Who Wants To Be A Pirate Radio Operator” at 0156z.
WMPR on 6925 AM “This is WMPR Dancy Party” ID at 0040z.
Captain Morgan Shortwave Radio on 6925AM “Positive Captain Morgan Shortwave ID, email, and twilight zone theme at 2209z.
Radio Ronin Shortwave on 6950AM oriental-sounding interval signal, id at 01:04, Outer Limits intro, “She Blinded Me with Science”, strange version of “SOS”, anti-BP comedy skits, id at 01:19
Indira Calling on 6925AM pop music that I can’t identify, “Rock-It”, Indian music, id at about 00:37, “Beach Party 2000” show, Calcutta mail drop, Beach Boys medley
WEAK Radio on 6925 Shout out to Voice Of Honor. 0048z “Godzilla” 0055z Sabbath.
Channel Z radio on 15067AM 2218z ID and contact info, must be an old show (Blue Ridge Summit maildrop)

And so on. Those call signs are usually spoofs on something. Occasionally, contact information is given out, usually in the form of a mail drop. If so inclined, one might write a letter and receive a QSL card.

There is plenty of information floating around out there about shortwave pirate radio if one cares to look for it. Two of the more popular discussion forums are HF underground and Free Radio Network Grapevines.

Should I renew my free subscription to Radio World?

When I left my former place of employment and set out as a contractor, I also left my Radio World subscription behind. After I was let go, or quit or whatever it was, I was thinking that my days in radio were over or at least winding down and I had bigger things to worry about than trade magazine subscriptions.

I have been checking the Radio World website and find that it gets updated from time to time, usually several weeks behind the magazine. So the question is, what am I missing? As one commenter on the radio info board put it, the magazine keeps getting smaller and smaller, soon they’ll have to rename it Radio Pamphlet.

I’d like to stay abreast of things in the technical end of the radio business, but is Radio World the way? There was a time when it was a technical magazine full of good timely articles well written by fellow engineers. Occasionally I still find something interesting to read, and that is true. Interspersed with that are lots of advertisements, useless information, and many pro-HD radio articles. Is it worth the price? I don’t know, I am still pondering that one.

Radio Ships

Radio London air studio aboard the MV Galaxy

These were broadcast platforms that were usually anchored in international waters broadcasting popular music to several European Countries including Great Britain, Holland, France, and Spain in the late 1960s through late 1980s. The reason for these peculiar operations was strict government control of all broadcast outlets and programming in those particular countries. The BBC was known to be stodgy and repressive of new music, particularly rock music from bands like the Rolling Stones, the Beatles, the Who, the Kinks, and others.

At the time, there was no specific law preventing ships anchored in international waters from broadcasting to shore-based listeners, a loophole in the government control was found and exploited. That loophole has been closed in most places, so as they say, don’t try this at home.

At one time there were several ships out there in the English Channel and coastal Denmark. The first and best-known of these was Radio London or “The Big L.” It broadcast on 1133 KHz from December 16, 1964, to August 14, 1967, using a 50,000-watt RCA ampliphase transmitter. The ship itself was the M/V (motor vessel) Gallaxy, a converted WWII minesweeper formerly known as the USS Density. After Radio London went off the air, the ship was transferred from port to port until it ended up in Kiel, Germany, where it was finally scrapped in the late 1990s.

Radio Caroline was the main offshore competitor, broadcasting on 1520 KHz and several other frequencies off and on from 1964 until 1990 or so using several different vessels to transmit from.

One incident in offshore broadcasting that has always fascinated me was the burning of the Mebo II, then transmitting Radio Northsea International off the coast of Holland (this ship moved around quite a bit) in 1971. Later investigations revealed that the staff of an offshore competitor, Radio Veronica, was responsible for the firing of the ship. Apparently, in those days the competition was brutal.

I like the nice calm music with the increasingly frantic DJ (West, no East). In any case, the ship remained afloat and returned to the air the next day. The final European offshore broadcaster was something called Laser 558 on M/V Communicator. It broadcast using to CSI 25 KW AM transmitters on 558 KHz in 1983, again, off and on for several years until 2004. The CSI-grounded grid transmitters may have been inexpensive to purchase, but I’ll bet they cost a lot to run. This would be especially true if one were using diesel generators as the main electrical power provider. As a result, they were usually run at about 1/2 power. Eventually, M/V Communicator ended up beached in the Orkney Islands off of Scotland.

The only such attempt in the US was Alan Wiener’s MV Sarah, known as “Radio Newyork International” anchored off of Jones Beach on 1620 KHz. The owners figured 4 miles offshore was far enough to be in international waters, but the FCC felt otherwise, I believe at the time, 12 miles was (and still is) the territorial limit for the US. Four miles was not international waters, as the broadcasters claimed. These guys were arrested and sent to trial. After several years all charges were dropped.

Anyway, an interesting bit of radio history. Goes to show the lengths that some will go to when feeling repressed.

Computer file manipulator

It just doesn’t have the same ring as Disk Jockey or DJ. However, that would be an apt description of the person who plays the hits on most radio stations these days.

It is mostly just drag and drop the next element into the play deck if anything needs to be done at all.

I remember when DJs actually jockeyed disks, it was a sight to behold. Back in the day when everything was on vinyl except the commercials, which were on the cart, the DJ had his or her hands full. Most of the songs were in the 2:30 to 3-minute range, so while the song was playing, the next song had to be cued up on the platter, the old song needed to be put back into its sleeve and shelved (most of the time), check the log to see what was on deck, pull the next commercial stop set, answer the phone and god forbid if the Program Director called on the hotline and it rang more than 3 times. And hopefully, the head wasn’t too far away, that coffee went somewhere, after all. While all that is going on, timing, audience interaction, hitting the post, and sounding fun. In spite of what Howard Stern says, it was not easy.

Today, of course, if there is even a person in the studio, they may glance up at the computer screen every now and then to see when the next time they need to talk. Otherwise, they would be engaged in talking on the phone with their girlfriend, texting, surfing the internet, or watching a baseball game on TV.
