[Spooks] HM01 and the Curious Incident/Happy Accident

First, a [minor] correction to my Tue May 27 02:18:58 EDT 2014 e-mail:

2014-05-27 06:28:00 UTC 14375KHz:
62216 28745 48505 44825 82404 51254
Excellent reception

The correction is that 62216 was the first RDFT Tx.  You can hear the
second half of the broadcast at
http://docs.google.com/file/d/0B3HdNvyAc7FRZEEyREozQ0c3QzQ (~50MB
MP3).



So... that's our "normal" transmission.  Next was the 07:00 UTC 13435
KHz, where I said...

Pedro had some trouble getting the Tx started.  As a result his signal
is quiet albeit strong.  Good Rx, though, as there's no QRN/QRM.

...which consisted of the following:

(1) "62216 2"
(2) transmitter goes off-air for about 2 minutes
(3) "825 82404 51254 622" with the last "2" cut off
(4) dead air
(5) "254 62216"
(6) more dead air
(7) "4"
(8) RDFT attention tone, and
(9) the normal HM01 broadcast.

You can hear this bit at
http://docs.google.com/file/d/0B3HdNvyAc7FRNk1Odkg0Mjk4VW8 (~10MB
MP3).  I shortened point 2 (when HM01 goes off-air) down to about 10
seconds.



At around 07:52:50 UTC there was another "Oops": an errant "1266".
You may have noted that sequence of digits doesn't jive with the
"normal" broadcast; at the time, I didn't.  This, too, can be heard at
http://docs.google.com/file/d/0B3HdNvyAc7FRNUxSQVNJZlRQOWs (~320KB
MP3)



But now we get to the weirdness: 07:59 UTC on 13435 KHz, HM01 is doing
its third callup, and outta nowhere I hear... "nueve"??

"called up a new batch of #s just before going off air.  Fortunately I
have a recording :-D Will make available ASAP."

Well, this is As Soon As [was] Possible:
https://docs.google.com/file/d/0B3HdNvyAc7FRTktyVDRMcjJhM1E (~4.5MB
MP3).  The exact transmission was "12661 76270 62101 75721 69180
66201, 12661 76270 62101 75721 69180" followed by dead air until
carrier-off.  (Just a small reminder that the "," indicates a pause
which in turn proceeds the first called-up number to be RDFTed).

At this point, a small recap of HM01's last callups seems appropriate...

2014-05-21 64318 99037 45567 83337 12054 44647
2014-05-23 12661 48490 62101 75721 12055 66201
2014-05-24 12661 76271 62101 75721 69181 66201
2014-05-25 12262 76272 62102 75722 69182 66202
2014-05-26 ????? ????? ????? ????? ????? ?????
2014-05-27 62216 28745 48505 44825 82404 51254

...because the extraneous callup comes very close to matching the
callup of May 24th:

2014-05-23 12661 48490 62101 75721 12055 66201
    05-27 12661 76270 62101 75721 69180 66201
2014-05-24 12661 76271 62101 75721 69181 66201

(Thanks to Ary and Shawn)

As I mentioned in a previous e-mail, either there was no 08:00-09:00
UTC transmission on 11635 KHz or I simply couldn't receive it.  Either
way, I have no clue if subsequent transmissions were "normal" (62216)
or "weird" (12661).
