Farewell to Bletchley Park...<br />
<blockquote class="tr_bq">
<div id="news">
The Milton Keynes Amateur Radio Society (MKARS), the
resident radio club at Bletchley Park for nearly twenty years, will be
leaving the Park as of the 1st January 2013. To mark this occasion MKARS
will be holding a 'QSO party' on the weekend of the 15th-16th December.<br /><br />All
MKARS members and ex-members are invited to come and operate GB2BP from
Generator House 2, our current premises at Bletchley Park, for the last
time.<br />GB2BP and MKARS will in the future only be operational from Bletchley Park by invitation during 'radio related' events.<br /><br />This
is possibly your last chance to operate this charismatic call sign. Be a
part of MKARS continuing proud history. If you do not normally attend
MKARS events, this one is a 'MUST'. So put the Christmas shopping on the
back burner and be there.<br />In the future you will be able to say 'I
WAS THERE, my name is in the log'. Will has threatened to cook burgers
and Dave is trying to obtain a 'Big Linear'.<br /><br />Tea and coffee will be provided. Hopefully some beer as well.<br />The
event will start early on Saturday morning, as soon as we can get on to
The Park and finish when we have to leave, and the same again on
Sunday.<br />We, MKARS, can walk out of Bletchley Park with our heads held
high knowing that all those years ago, when Bletchley Park was on its
knees, MKARS was one of the many local groups that helped make the Park
into the great museum it is today. MKARS is a great club with a great
future. Be a part of it!<br /><br />We have not lost The Park, The Park have lost us.<br />

E25a was heard using the WebSDR of University of Twente. This is great because listeners across the globe, can listen to E25 on 9450 kHz!<br />
<br />
A carrier was in progress at 1315z, 07/10/2012 on 9450 kHz. Then a 1000 Hz tone appeared and after a while the YL started calling "785 8". She ended with "Message" x3 at ~1319z. <br />

As I was scanning the bands, I found a peculiar transmission on 12371 USB at approx. 1237z (14/09). I am not sure if the tuning and mode selected is correct, but <a href="https://sites.google.com/site/hfsurfingblog/Home/12371USB_20120914_1239z_websdr.ewi.utwente.nl.wav?attredirects=0&d=1">here</a> is what I heard (recorded from the soundcard output), and this is a spectrogram image:<br />

It started at 1303z and lasted for a bit more than a half an hour.<br /><br />The session began with PC sounds, then a prayer, then again, sounds from the Windows game "Spider Solitaire". At 1317z and after a brief 1000 Hz tone, the YL counted 0-9, each number spoken in both variants. The second variant is used when the number is in the end of a numbers group. After a while, at 1323z a tone and the YL counting 0-6 this time was heard. The carrier stayed up with again some Windows sounds. At 1327z, an E25a message (785 2) was sent, and the session ended at 1335z, with some more sounds from "Spider Solitaire".<br /><br />And here is the <a href="https://sites.google.com/site/hfsurfingblog/Home/E25a_9450USB_20111215_1303z.mp3?attredirects=0&d=1">sound file</a> of the whole transmission.

That was her mistake. It still needs practice and patience to follow her. It is odd that sometimes, when the number which follows is the same, the pause in between is bigger.<br /><br />The strange (and funny) thing is that after the end of the transmission, at 1321 UTC, the YL started again, in a frantic pace. Then, at 1323 UTC, she was repeating "78" and then "Message" x3, "Rebeat" x3, "End of message, end of transmission" and a couple of WinXP sounds (the kind you get when you are browsing with Explorer" were heard.<br /><br />Anyway, <a href="https://sites.google.com/site/hfsurfingblog/Home/E25a_9450AM_20110421_1315z.mp3?attredirects=0&d=1">here's yesterday's recording</a> (trimmed for brevity).Manolishttp://www.blogger.com/profile/07016579904372221470noreply@blogger.com6tag:blogger.com,1999:blog-8282352521076076887.post-85918286346975671792011-04-09T20:42:00.006+00:002011-04-09T21:13:24.538+00:00Two E25 transmissions on 9450kHz, with lots of PC sounds<a href="https://sites.google.com/site/hfsurfingblog/Home/E25_9450AM_20110409_1315z.mp3?attredirects=0&d=1">The recording</a> starts at 1315z on 9450 kHz, AM mode. After the first transmission and during the second transmission, a lot of PC sounds are heard. Any ideas?<br /><br />Another transmission occurred on 9450 kHz at 1244z (a message to 440, which is the same since 22/02). Also, earlier this morning, a transmission occurred on 6140 kHz, at 0800z:<br /><br /><b>6421</b> <u>4880</u> 3351 9836 8953 3361 4186 6507 3344 4586 <u>4880</u> 5390<br /><br />The station was up at least since 0753z with OM music. WinXP sounds were heard again, the YL ended with “EOM 3...”.

The strange thing was, while being an E25a transmission (which means no message body), the YL said "Message" three times, and <span style="font-weight: bold;">continued</span> to call "785 46". Usually, a runaway "Message" can be heard during E25a messages but <span style="font-weight: bold;">in the end</span> of the transmission. After calling "785 46" a couple of times, the YL said "Message" twice, and the WinXP shutdown sound was heard.<br /><br /><a href="https://sites.google.com/site/hfsurfingblog/Home/E25a_9450AM_20110402_1313z.mp3?attredirects=0&d=1">Here is the recording of the full transmission. </a>Manolishttp://www.blogger.com/profile/07016579904372221470noreply@blogger.com2tag:blogger.com,1999:blog-8282352521076076887.post-44659785059897762492011-03-05T15:19:00.005+00:002011-03-05T15:50:15.129+00:00E25 transmissions today on 9450 kHzThis day we had three E25 transmissions, all on 9450 kHz.<br /><br />Here are the message details and recordings:<br /><br />1st transmission:<br />1219 UTC Carrier in progress<br />1228 UTC The song "Arouh Le Min" from Umm Kulthum was heard<br />1230 UTC Th YL started calling "555", with irregular spaces between numbers, sometimes the numbers are not "spoken" as a whole.<br /><br />1232 UTC "Message" x3<br />9104 <span style="font-weight: bold;">6031 </span><span style="color: rgb(255, 0, 0);">8741</span> 0413 3253 8882 6157 7803 8487 0312<br />8828 2497 <span style="color: rgb(255, 0, 0);">8741</span><br /><br />1235 UTC "Rebeat" x3<br />1237 UTC "End of message, end of transmission"<br /><br /><a href="https://sites.google.com/site/hfsurfingblog/Home/E25_9450AM_20110305_1228z.mp3?attredirects=0&d=1">Recording</a> (note, I accidentally switched to USB)<br /><br />2nd transmission:<br />1242 UTC Carrier<br />1244 UTC YL calling "440"<br />1245 UTC "Message" x3<br />8237 <span style="font-weight: bold;">4031</span> <span style="color: rgb(255, 0, 0);">4710</span> 2377 1161 8115 5905 2141 0105 3069<br />1730 7939 <span style="color: rgb(255, 0, 0);">4710</span><br /><br />1248 UTC Pause till 1249 UTC, then "Rebeat" x3<br />1252 UTC Ended with "EOM" only, carrier QRT at 1308 UTC<br /><br /><a href="https://sites.google.com/site/hfsurfingblog/Home/E25_9450AM_20110305_1244z.mp3?attredirects=0&d=1">Recording</a><br /><br />3rd transmission:<br />1342 UTC Music, "Arouh Le Min"<br />1345 UTC YL calling "227 17, 220 18 19 20, 222" irregular spaces between numbers<br />1350 UTC "222" repeated, then "Message" x3<br />5279 <span style="font-weight: bold;">4411 </span><span style="color: rgb(255, 0, 0);">0810</span> 5897 2744 2999 2440 4217 0585 4482<br /><span style="color: rgb(255, 0, 0);">0810</span><br /><br /><a href="https://sites.google.com/site/hfsurfingblog/Home/E25_9450AM_20110305_1342z.mp3?attredirects=0&d=1">Recording</a><br /><br />Note that during the third transmission, a BC station was on the same frequency, but here in my QTH, E25 is much stronger (+20dB or +30dB, while the BC station peaks S7)Manolishttp://www.blogger.com/profile/07016579904372221470noreply@blogger.com0tag:blogger.com,1999:blog-8282352521076076887.post-23036171216921498812011-02-13T13:45:00.002+00:002011-02-13T13:51:54.848+00:00Hooray!

The young lady has a variable rhythm. I suspect that the operators switched to Windows XP since there are reports of that particular OS sounds accidentally escaping to the airwaves. This may be the reason for the varying speech speed.<br /><br />Nowadays there are more reports of E25 on 9450 kHz probably due to the improving HF conditions.<br /><br />Enjoy!Manolishttp://www.blogger.com/profile/07016579904372221470noreply@blogger.com5tag:blogger.com,1999:blog-8282352521076076887.post-57762933707319783262010-12-02T13:53:00.004+00:002010-12-02T14:30:07.657+00:00An interesting E25 transmision with an exciting endingAnd another surprise from E25!<br /><br />The transmission began at 1214z on 9450 kHz, with the song "Inte Omri". Then at 1217z, the mechanical young lady, in a faster-than-usual pace, was calling "830 3 835". Then a message to 835 followed:<br /><br /><span style="font-family: courier new;">830 3 835</span><br /><br /><span style="font-family: courier new;">835 (repeated)<br /><br /></span><span style="font-family: courier new;">"Message" x3</span><br /><span style="font-family: courier new;"><br />1020 5555 x19 (an unusual message)</span><br /><span style="font-family: courier new;"><br />"Repeat"x3 (fast)</span><br /><span style="font-family: courier new;"><br />"End of message, end of transmission"</span><br /><br />Note that the pace was a bit faster, the gaps between phrases/numbers were a bit irregular and the endings of the number "five" were more abrupt than usual.<br /><br />At 1226z the message ended with the usual "EOM EOT" and then...the <span style="color: rgb(255, 0, 0);">Windows XP</span> <span style="color: rgb(255, 0, 0);">shutdown sound</span> followed! (And not Windows 98!) After this little surprise, the transmission ended.<br /><br /><a href="https://sites.google.com/site/hfsurfingblog/Home/E25_9450AM_20101202_1217z.mp3?attredirects=0&d=1">Here is (nearly) the whole transmission</a> (A part is missing from the beginning). The "rattling" sound is the digital station who usually interferes E25 when I use AM mode.<br /><br />So E25 operators upgraded their OS? But yet, the quality of the transmission wasn't as good as expected!Manolishttp://www.blogger.com/profile/07016579904372221470noreply@blogger.com3
