Polytones

Before we continue with PLondon’s tabulated results and polytone thoughts we mention a find from E:

He writes,

“5123kHz 2021z Polytone Like a high pitch XPH. Fast tones and never heard before. Off at 2023z.

The same tones were repeated at 2031 on 4837kHz and off at 2033z. All on 13/10.”

The choice of frequency for November appears to be a good one; despite some propagational changes signals have remained fairly strong and well readable, sometimes registering +40dBs at PLondon’s work QTH where he uses a well modified DX-394 fed by a 6 metre horizontal external antenna. JoA has generally reported better signals [than PLondon] with his vertical antenna, usually S9+ and mostly into the dBs range.

November’s log appears to indicate a decline in XP full message transmission. With eight possible sendings only five carry a message, the others being null.

PLondon’s words above were indeed echoed by PoSW who wrote,

“XP polytone;- the only remaining XP schedule of which I am aware - or am at home to monitor - has been logged in November with the first sending at 0700z on 10,862 kHz. When heard on Tuesday 5-November there was a "full message" transmission with an S9+ signal. On Tuesday the 23rd and on Tuesday the 30th the signal was still extremely strong but was of the "no message" format. This might be a bad omen because the long-standing XP and XPH schedules which used to be transmitted in the UK evening came up with several months of "nulls" before their final demise some time ago.”

Latest;- continues in December, heard on Tuesday 7-Dec and on Friday 10-Dec on 9,364 kHz, strong signal with "full message" format on both occasions. NOW READ ON……….

Not only is the message a 47 group one but we now have a tallymark preceding the first message group. [The first two sendings were noisy and variable in strength but also showed the tallymark].

Perusal of the historic chart below illustrates the sending/message history for December 2003. Note that the 81 group message sent on 16/12/03 actually corresponds with that sent 17/12/04 although the next message 21/12/04 of 47 groups was of less length than its corresponding message sent on 19/12/03. Note the tally mark on XP3 sendings; XP2 had already ceased.

MONTH: December, 2003 [taken from Issue 20]

Both PLondon and PoSW have observed that the messages of our last known regular XP schedule have changed. There have been more null messages than usual and the message content/group count has reduced too. This has been seen with the XP2, 2 and 3 schedules, all of which have apparently disappeared.

Like the current trend seen in the remaining schedule the previous XP2 and XP3 schedule messages used a tally mark. The messages were interspersed with a null transmissions and low group count messages, al l of which is being observed of the one remaining schedule. Of course these observations may not lead to anything at all, but in the recent past AnonUK has mentioned an increase in M12, the Morse equivalent of XP, messages.

The tally mark is generated by increasing the length on the space tone, 303Hz and can be seen highlighted in this spectrogram of the 0740z 21/12 sending from PLondon.

The tone concerned is 303Hz, the red lines are frequency marks used to denote the frequency limits of XP and occur at 303 and 516Hz.

Finally, the null message as received by PLondon at his Crystal Palace QTH, 73.4M above sea level:
