Utility / Re: XLA/XLB ALE who are they?
« on: November 19, 2016, 1132 UTC »
Hi Cornel,

Many thanks for this.

I was using the Twente SDR, my long wire antenna blew down earlier this year and I've not put it back up yet!

The only thing I noted was that as the evening wore on, the signals were stronger on the higher frequency channels- in fact I stopped hearing them altogether on the two 5MHz channels after about 21:00. I thought this odd as it is the reverse of what you would expect if they were 'local' i.e. European. But it could also indicate a source far to the east (in the daylight zone) I guess.

Utility / XLA/XLB ALE who are they?
« on: November 18, 2016, 1259 UTC »
Anyone know who these are?

XLA and XLB net
5106.2, 5210.2, 6393.0, 7505.7 ALE USB

Every 2-3 minutes on each frequency yesterday 17th November 2016, always XLB calling XLA:

[2016-11-17 20:07:03] [NORMAL MODE][TO][XLA][TO][XLA][EOM]
[2016-11-17 20:07:04]
[2016-11-17 20:07:04] [NORMAL MODE][TO][XLA][EOM]

Suddenly went QRT at 22:00 utc.

10417.5 is very busy this morning (14th Dec), I logged D10, Z80, H10, B10, Z71, I10, C10 sounding plus Z80 calling Z34 and Z71 calling D10 all in the space of an hour!

Utility / 10410 khz ALE

I'm hearing Forest Moor XSS sounding every 30 mins (approx 27 and 57 minutes past the hour) on 10140khz, which I don't see listed as a DHFCS frequency... no other stations heard... is this part of a known net?

HF Beacons / L beacon 6917: power supply smoothing failed!
« on: November 17, 2014, 1840 UTC »
The L beacon on 6917.5 is a good signal at the moment, but it is modulated by a raucous 100Hz hum, resulting in the signal being spread over several kHz.

HF Beacons / F is back to L again
« on: October 13, 2014, 2221 UTC »
Seems to confirm the short duration or special event status of the F (or C-F-F-F-F-F as it was) operation.

HF Beacons / Re: F beacon on 8498
« on: October 12, 2014, 1831 UTC »
Also on 6917.5 kHz, which is also a L frequency so seems to confirm the relationship. I read on Ary's N&O site that F appears for a couple days now and then, as if it were a 'special event' thing...

Recording: http://alancordwell.co.uk/dev/misc/cfffff.mp3

On 8497 kHz today 12/10/2014 at 1606 UTC via the Twente SDR

HF Beacons / F beacon on 8498
« on: October 11, 2014, 2214 UTC »
This frequency is where you usually find the 'L' beacon, today however it is sending F's- only every 6th 'F' is a 'C'! This beacon has a long history of being quirky- up until about 10 years ago it was chirpy and sometimes had the odd dit missing- as if a mechanical keyer was used that had bad contacts. Then it seemed to get an overhaul and behaved itself for a bit. Actual carrier frequency is about 8498.55

Other / 11354 kHz- hummy SSB transmission
« on: October 10, 2014, 1507 UTC »
On 11354 kHz 14:59 UTC today there is what sounds like a USB transmitter connected to a bad landline- it's sending continuous harmonicy hum; S3 or so with much QSB. Can't tell if the hum is 50 0r 60 Hz based. Can hear HFDL packets from Riverhead, NY through it so it's not that Tx!

HF Beacons / 'V' beacon 6928
« on: October 09, 2014, 2131 UTC »
'V' channel marker (letter) beacon on 6928kHz with its characteristically slightly short dash... Good copy now 22.30 9/10/2014, peaking at S7-8

HF Beacons / Beacon 'QRP' on 8000
« on: October 09, 2014, 2121 UTC »
There is a CW beacon sending 'QRP' at about 5 wpm on 7999.8, its about S4 here in Sheffield UK. I'm wondering if there's a connection with 'UFO' on a very close frequency that was reported a while back... It's a good stable T9 note with good clean keying.
