The dates for the 28 day cycle of these given in the Enigma Newsletter are not correct. The dates should be, February 10, March 9, April 6, May 4, June 1, June 29. M10E on 5019 is now on at 0900

E18

Where is E18? The last report was from October last year.

V07

The Tuesday and Thursday morning transmission has changed to 0710, 0730 and 0750 on 9283, 10353 and 11423 kHz. ID 234.

Atencion [V02]

John Maky noted a couple of frequency changes:

0300 UTC frequency change to 10446 kHz. 5800 kHz was silent while both 4174 and 6855 kHz are still active.
0400 UTC 5762 kHz, new schedule (4035 was active)
0400 UTC 6768 kHz, new schedule

 

Jeff Haverlah reported that he heard "a rapid variable tone sounding like a siren" at 0358 UTC on 08 February on 8992 kHz, followed at 0400z with a Spanish numbers transmission.

The station has been using 8992 kHz since at least early 1997. Most of the logs that I found were from 0800 UTC. These transmissions were logged on Tuesdays, Wednesday, and Thursdays. Apparently the 0400 UTC sked is on Tuesdays only.

John Maky says « This "siren" often precedes Atencion broadcasts. I believe the sound is created while audio/amplitude circuits are being peaked with a tone generator and oscilloscope. If you listen carefully; sometimes voices, tools clanking around (even parrots!) can be heard on the carrier during these adjustments.

You can frequently hear this same tone prior to E17 (English Woman) broadcasts. Hearing these test tones and a +60db/S9 carrier on an irregular frequency is a dead giveaway that an E17 transmission is imminent. »

Thanks for the info guys!

Cherry ripe [E03A/E04]

Paul Beaumont sent us the following question: « I have noticed on the E3a transmissions over Christmas season a chirp being broadcast after the transmissions. I am unable to copy those from 2200 to 0100Z. These chirps are also turning up on other freqs in the 5 and 6 MHz bands as well. The E3 freq of 14487 Hz was also affected. The chirp was heard as late as yesterday on 5071 kHz, to name one freq. I would be grateful to learn if any others have reported this chirp prevalent at all and particularly interested to find out if it has been heard on or around the late freqs of E3a. Thanks and good luck. Paul. »

PLO

Costas adds one frequency to the PLO frequency list that I put in last month's N&O: 14350 kHz. Can anyone confirm if these stations are still on SW?

EAM news

Another one from Jeff Haverlah. Jeff is a wellknown EAM enthusiast who wrote an extensive 2-part article about the subject which was published in this column back in 1995. For those who are interested, you can download a copy from the N&O home page (URL in the header). It's in 'N&O# 00'. Jeff recently posted the following update to WUN.

Or you can read it here for part 1 or there for part 2.
- From 01 Oct 96 the EAM universe on the US GHFS consisted of EAMs that were 6-characters in length (the preamble only), 20-characters in length, 30-characters in length (26-characters before 01 Oct 98), and strings 21-characters in length or longer (up into the low hundreds of characters; nothing heard over 300 characters since the huge strings of FY 95). There have been no strings reported or heard here that were between 6 characters in length and 20 characters in length (or at least any that I can find). Prior to 01 Oct 96 the situation appeared to be much the same from at least as early as the change from 5 to 6-character preambles around 01 Oct 91. Shorter strings existed in the 80s but apparently did not exist during the majority of the 90s on the GHFS.
As of the year 2000 this has changed. The 6/20/variable count series (currently using YG.. as their preamble's static characters) now also contains strings of 15-characters in length.
Examples:
24 Jan 00 1649z FIXG27
17 Feb 00 2352z YGGNY4


Also of interest, the E-6B hanging around the UK over the past two weeks has been passing strings on HF of 17-characters in length (at least 2 reported), and slightly longer strings of various lengths (greater than 20). He's been reported using the static series of "23..." over the last week, and "YD.." over this week, neither of which are being heard on the GHFS.

Thanks Jeff!
