Note the ident for September’s series as 935 – why is it not 035? No evening transmissions found as yet although a call from DoK did raise hope but was a piccolo transmission. [Tnx AnonUK for ident of sig].

0600z 21/09: Two breaks in this transmission. The first occurred 3.06m into the sending and lasting 1.374s affected groups 66 and 67; a further break, 46.153 sec later at 3.54m into the sending occurred after 3 characters of group 125, affecting groups 126 and 127 also. That break lasted 1.385m. The missing groups 66/67 read 41329/70965 and 125/126/127 as 73252/88555/44637.

November sendings will occur at 0700z

PoSW also monitored XP on Tues 05/10, he writes, ‘An early dental appointment gave me the chance to tune around the bands before setting out for a session under the drill.’ Peter logged the 0600, 0620 and 0640z sendings on 9148, 10788 and 12208kHz. Remarking on the 3mins 6secs sending. Peter also noted a strong carrier on 10988kHz that he thought possibly connected with XP. [Peter suggested that ‘someone in XP-land was playing with the transmitter set-frequency dials’].

On 08/10 the first sending suffered a loss of transmission [perhaps PoSW’s twiddler at work again]? PLondon writes, 'Note missing carrier between 2m44.44s and 3m36.40s. Corresponds to missing 5^th character [5] of group 42 through to the missing first and second characters [93] of group 103. The carrier was down for 49.96s and 60groups missed totally.'

A similar break in transmission occurred during the 0620z sending on 26/10.

XPA

“After many months stumbled on XPA last night (Weds 13/10) at 2200z on 5273 kHz. It lasted 2 mins, but unfortunately recorder wasn’t ready and I missed the start (it took me a few seconds to recognise what it was, then of course it was too late). It came in usual blocks of 64 x 5 fig groups. I don’t think I missed very much. The last block had 48 groups in, and I expect there were 5 blocks before that, making a probable 368 groups.”

[TnxRNGB]

RNGB discovered another sending as follows:

RNGB described the sending, which he detected by a heavy carrier ahead of its transmission, as “Lasting one minute, it was very fast at least twice as fast and detected in USB.” RNGB monitored the sending on the correct freq and at 1920z found:

At this point RNGB contacted PLondon and both searched for the expected, but never found, third transmission around the 4000kHz band.

After his reception of the 1920z sending RNGB did some signal analysis an emailed his findings to E2k:

“I’ve decoded first 2 groups of XPA on 5177 kHz at 1920z today. It reads 00622 00490 There were 10 blocks of 48 groups plus 12 at the end. So that gives total of 492, which leaves 490 for the text. It was sent twice as fast as normal, and I think before we either had blocks of 32 or 64.”

Note how the sending is constructed, 10x48 blocks against our expected blocks of 64, or 32.[Tnx RNGB, excellent stuff].

RNGB describes the signal as

"Seemed to consist of 4 tones (2 pairs) sent together. The difference between the pair of high tones equal to the difference of the low tones. There would appear to be 5 different sets of high tones and 5 sets of corresponding low tones. The sequence seems to repeat itself after 12."
