One short pirate broadcast I caught last night was All Along The Watchtower Radio.

AATW Radio’s USB signal on 6.955 MHz started around 00:24 UTC (23 March 2013).

The (robo voice) host, Alex Jobs, played a great mix of music starting with a version of Video Killed the Radio Star by The Presidents of the United States of America. It actually sounded pretty good in upper side band!

Hear for yourself! Click here to download the MP3 recording of the full broadcast, or simply listen via the embedded player below:

"Mom, could that be The Presidents of The United States of America? How patriotic!"

Rijmenants’ paper sheds light on Cuban numbers stations

WFL_015I’m always amazed by the remarkable talents and extraordinary knowledge of SWLing Post readers. Dirk Rijmenants recently commented on one of our Cuban spy numbers station postings:

[T]hanks for your work on this fascinating blog.

I have additional information on how and who used these Cuban numbers stations. I composed a paper based on FBI and court documents. “Cuban Agent Communications” can by found in the Papers section of my website.

Here’s the direct link (pdf):

Have fun reading!

I’ve read Dirk’s paper, which does, indeed, shed light on the process of receiving and decoding numbers. Most of all, it exposes the vulnerability and fallacy of using anything other than one-time decryption keys and single-use pads. Why? Most of what the FBI has learned about Cuban numbers came from laptops that were used to help decrypt coded messages–an unnecessary procedure when numbers can simply be decoded on note pads that can then be burnt or destroyed.

But don’t take my word for it–download and read Dirk’s paper “Cuban Agent Communications” by clicking here. Also, be sure to check out Dirk’s blog and cryptology website; I’ve bookmarked both.

Thanks for sharing your findings, Dirk!

PCJ Radio International radiogram, March 31st

On March 31st, 2013 PCJ Radio International will conduct a digital text through analogue shortwave broadcast of a radiogram.

Setting: MFSK32

Date: March 31, 2013

Time: 0227UTC

Frequency: 9955khz

This test will have a message in English and Spanish for listeners in Cuba and Latin America. Those in the South Eastern part of the United States will also be able to tune in and record the 2 to 3 min transmission. If all goes as planed the Cuban jamming against 9955 kHz won’t have any effect on the message we will transmit.

VOA Radiogram: March 23/24 broadcast

Leave a reply

VOARadioGram(Source: VOA Radiogram)

VOA Radiogram for March 23/24 will be similar to the past weekend’s program in that it features the PSK modes. Much of Kim’s script will be the same. In this weekend’s broadcast, however, only one mode at a time will be transmitted. This should improve the signal-to-noise ratio and ability to decode each mode.

Each will be centered on 1500 Hz:

  1. BPSK31 (1:00)
  2. PSK63F (1:00)
  3. BPSK63 (1:00)
  4. PSKR125 (1:00)
  5. PSKR250 (1:00)
  6. PSKR500 (1:00)
  7. PSKR1000 (1:00)
  8. PSKR125 (3:45) Plain text
  9. PSKR250 (2:40) Flmsg* formatted (with html)
  10. MFSK32 (0:55) Image

*Install Flmsg. Then, in Fldigi: Configure > Misc >  NBEMS > under Reception of flmsg files click Open with flmsg and Open in browser, and below that state where your Flmsg file is located.

If decoding performance is still not satisfactory, VOA Radiogram in future weekends will feature more robust modes, such as MFSK, MT63, and Olivia.

See VOA Radiogram: how to decode the modes.

VOA Radiogram transmission schedule
(all days and times UTC)
Sat 1600-1630 17860 kHz
Sun 0230-0300 5745 kHz
Sun 1300-1330 6095 kHz
Sun 1930-2000 15670 kHz
All via the Edward R. Murrow transmitting station in North Carolina.

VOA Radiograms Today (17 March 2013)

The third airplay of VOA Radiogram is coming soon, at 1300 UTC, on 6095 kHz. Another, directed to Europe, will be at 1930 UTC on 15670 kHz.

Thanks to the many listeners throughout Europe, North America, and even in Asia, who have sent reports, audio, screenshots, spectrum displays, etc. After the last transmission today, I will summarize the results in this website.

WRMI, Radio Miami International, 9955 kHz, is transmitting IDs in the Olivia 8-1000 mode until 0400 UTC Monday (midnight EDT). These are centered on 1300 and 2500 Hz. Don’t be discouraged by the low signal level of WRMI, or by the Cuban jamming on the frequency. You might get a good decode of Olivia 8-1000 anyway.
