Oddities

Of the one tone two buzzes [1T2B] mentioned in NL10 JoA again writes, "11116kHz. Strange goings on: There seemed to be slight variations in 1T2B in that at 0608:04z & 0626:04z [03/05]. The long 10 sec. tone appeared to be replaced by Tone of a few secs then a series of very short ones (pips) then another tone of a few secs. After this it returned to the usual 10 second tone. The two buzzes as usual throughout."

JoA noticed some variation on the morning of 08/05. The long tone was replaced by a series of short tones (pips) and a longer one at the end. Once or twice the two buzzes had been missing. On one occasion the tone period appeared to be slightly shorter than the usual 10 seconds, whilst on another the long tone seemed to be replaced with a series of short tones (pips). This peculiar sound has been missing but was heard again by JoA who writes '1T2B has reappeared on 11116kHz USB Sat.15/06: 1826:04, 1835:04 through to 1847:04 & 1853:04 through to 1905:04 much as before. 1 tone (10 secs.) Pause (6 secs.) 2 buzzes (6 secs.) Total time 22 secs. First in hour: xx02:04, last in hour: xx59:04.'

E reports a series of 'rasps' which he describes as follows:

19180kHz	1306z	02/06	[2 tone rasp every 2 secs].
19586kHz	1307z	09/06	[3 rasps every 4 secs - same as 20480kHz].
20480kHz	1144z	02/06	[see above - 19586kHz]

Backwards music station (XM)

No reports.

Crackle(XC)

This peculiar sounding signal has been reported for 2002 by 'C' as being heard, during the evening, on

5495 and 5505kHz. 'The Crackle' an old friend was noted again on SAT 15.12.01 and is still operating in the European evening time. The Crackle on 5495 // 5505 under Shannon Air Radio, is back ! Like a dog to a lamppost it as returned to its only known frequencies - where as it been ? Still crackling away for no apparent reason. Listen while you can for hours of entertainment. Any one any ideas on this ?

Gert of Holland confirms 'C's observations by hearing XC on a Thursday evening:

5496/5504kHz

2248z

20/12

our recent report comes from E:

5505kHz

0143z

05/05

Jet (XJT)

Continuing with his audit of XJT, PLondon has taken good advantage of the Jubilee holiday to carry out further observations of this peculiar, but very necessary signal. Observations made on the night of 31/05, early and mid-morning of 01/06[31/05 2145z to 0035z 01/06 and 1237z to 1326z 01/06].

Shown as freq, time, signal strength [time, signal strength if heard midday 01/06] or if freq not listed prior to midday 01/06 Freq, time, signal strength.

[Signal strength: 9+ means greater than 9 but less than 10dB. +10 means 10dB over 9].

The allocation tables within Great Britain's Radio Communications Agency document RA306 indicate that all of the above XJT freqs fall in bands designated 'Government Use'. Looking at the comments there are some other allocations, usually Maritime and occasional Aero service [NATS comms etc]. Of interest it is noted that this most disruptive 'Jet' signal does not seem to clash with other users. All Amateur bands seem 'Jet' free as do the Aero service bands.

Wopwop (XWP)

The freqs stated as the 'schedule' for this particular signal appear to be barren over most of May. Has the schedule changed, finished or what? Whilst C reported a like signal around 1900z in the frequency range 13950 to 13965kHz PLondon has noted another WOPWOP like signal:

15660kHz

0027z
