Oddities

During the evening of 7^th July PLondon received a sound sample from mndbs. The sample was a few seconds of two tones = 575/805Hz.

The signal appeared to be two tone signaling. The spectrograms below illustrate the manner in which the tones are utilized:

Other info re oddities was received from E [see Carriers] as well as:

Generator noise: 10427kHz 0510z 17/07 wide b/w 14kHz

Crackle

In the last Newsletter we reported E’s intercept of ‘noise like the crackle’ on 4405kHz 1935z 27/05. At around 2020z 06/07 the relative quiet of PLondon’s shack was interrupted by a ‘FLASH’ message and a telephone call to MoK was started.

On 6650kHz was to be heard a crackle, not ‘The Crackle’ but a crackle indeed. Nearby was a hefty carrier and signal. With a bit of corroboration MoK and PLondon investigated the crackle to discover the frequency actually changed. The range of the peculiar signal moved between 6640 to 6650kHz and a varialble bandwidth if 10 to 22kHz was measured.

Attempts to gain a spectrograph was difficult.:

Faders

In his search for Polytone info RNGB has discovered that Fader were the US-mil 4 frequency modem. Not heard for some time and believed to be defunct.

Jammers

These can be heard with some regularity on: 5320, 5600, 6420, 6880, 7040, 7050, 7070, 8320, 8340, 8515, 9360, 10280, 10470 and 13410, 16176kHz.

Buzzer [formely XB] S28

It buzzes away on 4625kHz. www.geocities.com/uvb76 refers.

S30 [The Pip]

Continues to dominate 3757kHz in the 80M band also 5403.9kHz.

2 second pip heard by E:

20456kHz 0426z 23/07

Slot machine [XSL]

XSL is heard on 4152.5, 4231, 4290.5, 6249.5, 6416.5, 6444.5, 8312.5, 8587.5 and 8703.5kHz. USB mode

Still being heard in US, Oceania and like areas. E2k would like to receive details of any observations made in Great Britain, Eire and Europe please.

XSL general transmission times [freqs of 8588.0//8703.5]

Sun	1500z	1600z	1900z
Mon	0900z	1700z	2215z

Sat	1400z	1600z	1700z

The text via <http://www.geocities.com/hfasia/files/Japanese-PSK.html> describes the Slot Machine as Japanese PSK with a Vertical bandwidth of 3kHz. It states frequencies in use as:
4152.5, 4231, 4290.5, 6249.5, 6416.5, 6444.5, 8312.5, 8587.5, 8703.5kHz

XWP [Wop Wop]

This particular sound can be heard doing its stuff around the 6 and 8MHz bands. Note that the signal changes frequency every 20 mins and takes the odd break too. Believed to be Coastal Radar, samples exist in our sound samples file in group.

6807kHz	1905z	09/06	to 6825kHz	E
9238kHz	1909z	10/06	to 9257kHz	E
9388kHz	0557z	31/05	whilst waiting for XP	PLondon

XFR has been mentioned in passing and heard on a range of freqs near to a number of expected number station freqs.
