Channel markers [S28, S30, XP, XSW]

XP: Rimantas checks in with a note in which he says: "Some people wrote in the mailing list, that they could not hear "XP" on the lower frequency. However, the nighttime channel is alive at 3756 kHz." To illustrate this he adds a log from 8 May, 1752 UTC, when he heard a control message in Russian, female voice, repeated 3x: "For 389, 132, 984, 620, 996, 285, 196, 077, 630, 640. How do you read me? Over."

The day frequency of this station is 5448 kHz. Rimantas can hear it loud and clear but I cannot hear it here in Holland.

Below is a current list of the most active Russian channel markers:

3828     Squeaky Wheel
3194 R 24 hrs. Regular voice messages
3756 "XP" Nighttime channel. Regular voice messages
4325 R 24 hrs. Regular voice messages
4625 UVB-76 24 hrs. Rare voice messages
5448 "XP" Daytime channel. Regular voice messages
5465 R 24 hrs. Regular voice messages

Polytone stations [XP, XPL, XPH]

Who is Who in Polytone land? I'd suggest that you read the discussion about this subject in the ENIGMA newsletter #10.

There are currently three different sounding signals, coded XP, XPL (low pitch), and XPH (high pitch). The ones that we called XPH for years are now superseded by a higher variant, consequently the old XPH is now known as XP. Confused? You'd better be :-)

So when can you hear these babies? XP has schedules on Tuesdays, Thursdays and Fridays.


XP frequencies for May were:

Tuesdays and Fridays 0600 UTC 11157 kHz
[Schedule 148] 0620 UTC 12457 kHz
  0640 UTC 13857 kHz
Tuesdays and Thursdays 2000 UTC 14598 kHz
[Schedule 545] 2020 UTC 13417 kHz
  2040 UTC ??5?? unknown
Tuesdays and Fridays 2010 UTC 15913 kHz
[2nd schedule -963-] 2030 UTC 14694 kHz
  2050 UTC 13374 kHz


It uses higher tones, and the same format and preambles as M12, is only heard at present on Tuesday and Saturday. The May schedule was 383.

1830 UTC 16350 kHz
1850 UTC 14870 kHz
1910 UTC ??3?? unknown


It is very rare and is/was used by the same group as M10E.

Fapsi [M42 / X06]

In his "Radio Intrigue" column, Don Schimmel writes "A few FAPSI transmissions were heard during the month but judging from the weak signal strength, they were certainly not coming from Cuba."

As expected, the FAPSI activity from that area completely dried up after the Russians have left Cuba. Although the number of reports is only two in May, that doesn't mean that Moscow is slowing down. So far, there is no evidence that the European activity is decreasing.

11411 kHz 1951 UTC link 40034
14642 kHz 0650 UTC link 30011
16227 kHz 1042 UTC link 40034
20690 kHz 1055 UTC link 80038 to RPO, QSX 23131 kHz
23131 kHz 1057 UTC link 80038, QSX 20690 kHz


One mazielka (X06) log this month: 20437 kHz, 1038 UTC (31 May).

Unid station

22856 kHz, RTTY 99bd/417Hz, sending 274 274 274 etc. Picked up at 1335 UTC on 06 May and still going at 1556 UTC.

OTHR / Ocean surface radar

Radar activity was noticed on a number of frequencies this month.

Besides the ones that I mentioned in the past few months, the following signals were noticed:

3764 kHz Woodpecker
10080 kHz a strong one in Europe. covers 10040-10120 kHz.
18090 kHz the "Havana gurgle". Tone bursts each 43.88 msec.
21025 kHz covers 20950-21100 kHz, 4 double pulses per sec. Beam suggest Europe as place of origin.
24975 kHz CODAR radar sweeping down 25000-24950, each 498.1 msec.
28003 kHz pulses.


From radio amateur sources we heard "There were 12 reports for the NATO Over-The-Horizon-Radar from Akrotiri, Cyprus. The lowest frequency was 18000 kHz, the highest frequency was 29050 kHz. The bandwidth is normally 50 to 60 kHz, the signal strength S9 + 70 dB thus causing very harmful interference to the Amateur Radio Service."

As usual lots of jammers in the 7 MHz band at: 7000, 7005, 7010, 7020, 7022, 7030, 7040, 7050, 7070, 7080 and also on 14200 kHz. The 7 MHz jammers were mostly from Iran and Iraq.

The Simplex Voice Repeater on 28185 FM was again active in May. Every word spoken, every noise on 28265 is repeated on the same QRG after some seconds. Location of the station is near St. Petersburg, Russia. <source: IARU Region 1 Monitoring System News Letter>
