Seasonal Pirate Radio Stations

Tune into the 43 meter pirate radio band, which is roughly 6800 to 7000 kHz, but 6925 kHz in particular, on any given evening, and you’re likely to hear one or more broadcasts. While many stations transmit throughout the year, there are a few seasonal stations that you will only hear on certain days. To help you keep track of these stations, here’s a short summary of the more widely reported seasonal pirates. Note that the schedules of pirate radio stations are very flexible, and often broadcasts of these seasonal stations will be heard on a nearby weekend instead of the actual holiday, when there are usually more listeners.

I’ve also included QSLs from some of the stations.

WMLK – Recordings of speeches by Martin Luther King Jr, usually around his celebrated birthday, the next is January 18, 2016.

Voice of Pancho Villa – Heard during the time the NASWA Winter SWL Fest, which is usually in February.

WPDR Presidents’ Day Radio – Heard around Presidents’ Day with recordings of speeches by various Presidents. In 2016, Presidents’ Day is February 15.

Frederic Chopin Radio – Plays classical piano music, heard on our around his birthday of March 1.

XEROX – A classic parody of a Mexican radio station, usually on the air April Fools Day (April 1).

Radio Cinco De Mayo – Heard on or around the Mexican Holiday on May 5.

KHAQQ / Amelia Earhart Often heard on or around July 3, with simulated communications between ground station NRUI and Earhart (KHAQQ), trying to locate her.

Radio Paisano – A program of Italian related music which airs around Columbus Day, which is next observed October 10, 2016.

Halloween themed stations – Lots of stations are heard around Halloween, here’s several of the most active:
Peskie Party Halloween
Pumpkin Patch Radio
Radio Halloween
Satan Radio
The Great Pumpkin
WAHR Automated Halloween Radio
Witch City Radio

Edmund Fitzgerald Radio – Commemorates the sinking of the ship with the Gordon Lightfoot song as well as recordings of marine communications. Heard on November 10.

WJFK – Usually on the air around day of President Kennedy’s assassination, November 22. Traditionally, the station plays these three songs:
“Abraham, Martin & John” by Dion
“Sunny” by Bobby Hebb
“PT-109″ by Jimmy Dean

Another variant has appeared in recent years, which plays recordings of news announcements of the assassination.

Turkey Breast Radio – Heard on or around Thanksgiving.

Happy Hanukkah Radio – Heard during the eight days of Hanukkah. Usually the following is heard:
“Miracle of Miracles” from Fiddler on the Roof
“Hava Nagila” by the Effi Netzer Singers
“2000 Year Old man” skit by Mel Brooks.

Christmas themed stations – Another popular holiday for pirates:
Fruitcake Station
Radio Jingle Bells
Snowball Radio

Irregular stations:

WUBR Ultimate Blizzard Radio – Occasionally heard during major snowstorms.

Victory Radio – Heard when University of Texas wins a football game.

Poor conditions for some on 43 meters last night, better for others

One measure of the strength of the ionosphere is called foF2. It is the maximum frequency that will be reflected straight back. That is imagine the radio transmitter and receiver are located near each other, the radio waves go straight up, and are reflected straight back down to the receiver. foF2 is continuously varying, based on solar activity, and what part of the Earth the Sun is over. You can find a real time map at this URL:

As the distance between the transmitter and receiver increases, the radio waves are not perpendicular to the ionosphere, but instead strike it at an angle. This allows frequencies higher than foF2 to be reflected. The angle that the radio waves strike the ionosphere depends on the distance between the transmitter and receiver, and the height of the ionosphere, which unfortunately also varies. This is called the hmF2, and there’s a real time map of it also:

The Maximum Usable Frequency (MUF) can be found by:
MUF = foF2 * sqrt( 1+ [D/(2*hmF2)]^2) where D is the distance in km.

Lately, foF2 has been reaching very low values once the Suns sets. This is what causes the 43 meter band to “go long”, making it difficult to impossible to hear stations even many hundreds of miles away. As an example, here is a plot of the measured foF2 value taken over Wallops Island, VA. Consider these values typical for much of the eastern US during this time period:

The blue trace is today’s foF2 values, red is yesterday’s, and the green trace is an average of the last five days.

foF2 was about 5 MHz at 2300z, dropping to 4.5 MHz by 0000z. This was evident in the loggings for The Crystal Ship. Many listeners who normally get a strong signal from this station had poor or no reception (as was my case). This was also the start of a geomagnetic storm, the K index at 0000z was 3, and has since risen to 5 as I type this.

The flip side of a low foF2 value is that listeners at a greater distance from a station can get stronger signals. The geomagnetic storm last night could also have actually enhanced reception for some listeners. Medium wave DXers have referred to geomagnetic storms as “stirring the gumbo”, bringing in a different mix of station than are normally heard.

Update – here is the link to the real time Wallops Island foF2 chart: and the current graph itself:

Winter 2014-2015 Snowfall

Thursday November 13, 2014:
0.5 inch snow.

Wednesday November 26, 2014:
0.56 inch of rain, changed to snow early morning
3.9 inch snow.
Changed to graupel as it was ending.

Science experiment with the kids:

We cut a block of snow from outside, 12.5 by 9 by 7.5 cm, and computed the volume: 843.75 cm3. We shaved the top to make sure it was even.

Then we took the snow and weighed it, and came up with 160g.

We melted the snow and measured the volume, and got 160 ml (nice to see the agreement).

Then we computed the snow to liquid ratio: 843.75/160=5.27.

Our measured snow depth here was 3.9 inches, so that is 0.74 inches liquid. We got 0.56 inch of rain before it switched to snow. So rather impressive 1.3 inches of liquid total.

A Statistical Analysis of A Somewhat Subjective Rating of the Day’s Weather

Below is an analysis of the Capital Weather Gang’s “Daily Digit”, a number from 1 to 10 given each morning to the day’s expected weather. 574 days worth of Daily Digits were analyzed, from March 19, 2013 through October 13, 2014. The starting date was picked as that was the first date where it was easy to get a copy of the CWG’s archived web pages.

The mean daily digit was 6.32.

Below is a trend graph of the Daily Digit, smoothed slightly to make it more readable:

The slope upwards over time could be an artifact of the range of dates chosen, or it could be genuine Daily Digit Inflation.

Below is a histogram of the Daily Digit values:

There were only five days with a Daily Digit of 1; they were:

June 13, 2013 – David Streit (Severe weather)
December 9, 2013 – Jason Samenow (“Sloppy, cloudy and cold”)
December 29, 2013 – Brian Jackson (“40s and soaking rain in December”)
January 3, 2014 – A. Camden Walker (Icy from snow the night before)
January 28, 2014 – Matt Rogers (“Cruel cold slaps us in the face again”)

The mean Daily Digit per month of the year:

The mean Daily Digit per day of the week:

The mean Daily Digit per author:

There is a fairly regular rotation of authors, each generally writing on the same day, hence the strong correlation between the above two graphs. Each author had between 73 to 81 posts.

Not included in the above were the following two authors with a limited number of Daily Digits:
Kathryn Prociv: 10 entries with a mean of 8.3
Rick Grow: 8 entries with a mean of 5.0

There were also a few cases where two authors were credited the same day, also not included above:
Matt Rogers;Jason Samenow: 3 entries with a mean of 3.33
Brian Jackson;Dan Stillman: 2 entries: with a mean of 3.5
A. Camden Walker;Ian Livingston: 1 entry with a mean of 2 (January 10, 2014, Freezing Rain)
Dan Stillman;Ian Livingston: 1 entry with a mean of 4 (February 15, 2014, Snow)
Dan Stillman;Jason Samenow: 1 entry with a mean of 3 (February 26, 2014, “Mother Nature hits the repeat button with light morning snow”)

A big thanks to the Capital Weather Gang for their fabulous posts each day!

Old Time Radio – Shortwave Pirate Radio Station Or Something Else ?

For about the past three weeks, we’ve had a bit of a mystery on the 43 meter pirate shortwave broadcast band. First logged on the HFUnderground on May 18, 2014 on 6772.6 kHz by EvilElvis as an UNID pirate playing “Tooth Powder commercial, 5 Minute Mystery, Red Skelton, Avalon Cigarettes commercial”, this station has been heard nearly non-stop since then, except for some short breaks, and a two day period between June 3 (it was last heard on June 2 at 2357 UTC and returned by 0035 UTC on June 5.

This station has been heard from coast to coast, and has a over 170 loggings on the HFUnderground Pirate Shortwave Radio Forum and has become quite the favorite of many shortwave pirate radio listeners. Many of us where disappointed when we turned on our radios on June 3 to just hear static, and equally thrilled to hear the station again when it returned two days later. I’m hearing it on 6772.6 kHz as I type this at 1323 UTC on June 6, 2014. It generally operates close to 6772 or 6773 kHz, but as also been heard on 6800 and 6880 kHz.

Possibly the same station was reported in the 13.56 MHz HiFer band previously. Glenn Hauser first logged it on 13560.7 AM on April 18 at 0520 UTC, and mentioned the following to me via email:

I haven`t heard it on any of the 6 MHz frequencies, but I keep wondering if it`s the same one I have reported thrice on 13560+. That would be 2 x 6780+ if that was ever a fundamental. Looking thru the posts (not sure I saw all of them) I don`t see anyone referring to that or to the webcast ID I heard from the 1920s Radio Network out of WHRO in Virginia. Should compare the programming to their schedule. They also have a separate mostly-music channel. 13560 was also pointed out to be a part 15 RF ID frequency which be some connexion.

The 1920s Radio Network has a website.

The general format seems to be playing music (often described as easy listening music, or even elevator music) during the daytime, and then old time radio shows overnight, hence the nickname Old Time Radio given by several listeners. No formal ID has ever been heard. News is typically heard at the top of the hour, and seems to be syndicated news audio provided by “Feature Story News“. I’ve noticed that today, June 6, I am not hearing any news.

The first thing that comes to mind is that this is a pirate radio station. There’s no SWBC stations assigned to these frequencies. While speculation about pirate radio station transmitter locations is often frowned upon by parts of the pirate radio community, propagation (based on who can hear the station at various times of the day) clearly shows that the transmitter site is somewhere in the northeastern USA or southeastern Canada. That is pretty obvious. And the signal levels are typical of what you’d expect from a pirate station running something on the order of 100 watts, give or take a factor or two or three. But the surprising thing is how active the station is, running nearly 24/7. Someone’s not that afraid of enforcement activity by the FCC. Or could it be something else, like a radio contractor doing some testing? It seems unlikely, but then again, we had the famous Yosemite Sam station years ago.

So, if you’ve wanted to hear a pirate radio station, but always seem to miss them, now is your chance. Just tune around 6772 when propagation favors reception in your location from a station somewhere around the northeast USA, and you may indeed hear Old Time Radio, or whoever they are.

June 7 Update:
At 2129 UTC on June 7, 2014, the station went QRT on 6771, then came back on 6976 (a new frequency for it) at 2136 UTC.

DX Toolbox 4.3.0 Released

Version 4.3.0 of DX Toolbox, the radio propagation app for Windows and Mac OS X has been released.

This version adds the Ionosonde Plot Window. This window lets you see graphs of ionosonde data from a number of sites around the world. Select the site from the first popup menu (there are dozens of sites around the world), then select the type of graph from the second. There are three types:

foF2: This is a plot of the highest frequency that will be reflected from the F2 layer of ionosphere when transmitted straight up. As the incident angle is decreased, higher frequencies will be reflected, that is, more distant stations can be heard, or alternatively, more distant locations can receive the signal. This effect explains the “skip zone” around a transmitter site.

foEs: This is a plot of the highest frequency that will be reflected from the E layer of the ionosphere.

hmF2: This is a plot of the height of the F2 layer of the ionosphere. Along with the foF2 value, it can be used to calculate the MUF for a given path.

Here is a screenshot of what the window looks like, click on it to see it full sized:

DX Toolbox also displays a variety of other information, here is the main window of current space weather:

There is also this chart of recent solar and geomagnetic conditions:

Several propagation forecasting tools are also available. This one computes the MUF (maximum usable frequency) and LUF (lowest usable frequency) between two locations, as well as the estimated received signal levels:

You can read more about DX Toolbox here, and see more screenshots here.

Copies of DX Toolbox for both Windows and Mac OS X can be downloaded from the download page.

An version (minus a few features) is also available for the iPhone and iPad.

If you think there’s been more pirate activity during the shutdown, you’re right!

Here’s a graph showing the number of unique pirate logging threads on the

Each thread represents a different shortwave pirate radio broadcast. The red bars on the right are the number of broadcasts during the shutdown per day. I’ve also drawn in green the average number of broadcasts per day during the month before the shutdown (6.9 per day) as well as during the shutdown (12.2). As you can see, activity is up 77%. This past weekend was extremely active, setting records.

Receiving HF Weather Fax Transmissions On Your iPad, iPhone, iPod Touch or Android Device

It’s markably easy to receive weather fax transmissions without a computer today, you just need an app for your smartphone or tablet, along with an appropriate shortwave radio. This can be extremely handy for mariners who do not have internet access at sea, but want to be able to receive weather charts to keep abreast of storms and other potentially dangerous conditions. It’s also a way for radio hobbyists to decode and view weather fax transmissions without using a computer.

For the iPhone, iPad, and iPod touch, there’s the HF Weather Fax app from Black Cat Systems, available on the iTunes store:

An Android version is also available on the Google Play store:

Under good reception conditions, very high quality weather fax images can be received (click the image to see a full sized version):

A radio capable of receiving the transmissions is also required. Most SSB marine radios should be able to do this, in addition there are many relatively low cost consumer radios that will also work, such as the Sony ICF-SW7600GR .

Next, you need to get the audio from the radio into the tablet or smartphone. While there are some patch cables that will work, weather fax is fortunately a rather forgiving mode to receive, and often just placing the device’s microphone next to the radio’s speaker (or better yet next to some headphones plugged into the radio) often works quite well.

Weather faxes are sent several times a day from dozens of locations around the world. NOAA has their online Worldwide Marine Radiofacsimile Broadcast Schedules listing them by region and country, and is an essential resource. The frequencies listed are carrier frequencies, to tune them in USB mode on your radio, subtract 1.9 kHz. For example, NMF from Boston MA transmits on a carrier frequency of 6340.5 kHz. Your radio should be set to USB mode, and tuned to 6338.6 kHz for proper reception.

Both of these apps will automatically detect the start of fax tone sent at the beginning of an image transmission, to properly align the image. They will also detect the end of fax tone, and use that to save the image, for later viewing. Note that relatively good reception is required for proper detection of the start and stop tones, a weak signal or lots of static or interference (or even audio pickup from the microphone) can cause the tones to be missed.

Here’s a short video made by a user of HF Weather Fax on the iPad:

And here’s a video showing the Android app:
