XPH

The december XPH skeds were posted by Valeriano Martin, who also informs us that XPH has a regular sked on Tuesday and Friday at 2110, 2130, and 2150 UTC since November.

Tuesday and Friday skeds:

0700 11024 0720 12224 0740 13924
2100 6848 2120 5776 2140 4637
2110 6934 2130 5927 2150 5359

 

Using Valeriano's XPerta program, I was able to decode the messages. Here is the message that was sent on 12 Dec. at 2100/2120/2140 UTC.

Sweeper

The 4 MHz sweeper is possibly a radar signal. 1/3 of 14275-14381 kHz matches the frequency range 4758-4793 kHz, which is exactly the spot where the signal was heard. I copied the following from the ARRL news letter:

« The FCC tentatively has identified a mysterious "tick-tick" intruder signal as the third harmonic of an ocean current-sensing radar near Atlantic City run by Rutgers University. The FCC directed the licensee to eliminate the harmonic but did not order the transmitter shut down. The transmitter manufacturer has since installed a low-pass filter to eliminate the interference. The "tick" showed up from 14.275 to 14.381 MHz.
The typical signal of the experimental Rutgers radar system is 25 kHz wide. While the tick was audible, it did not present significant interference to amateurs. »

xxx7 stations

The propagation stations as described in last month's column were also heard in December. DFs suggest that the signal originates in the Moscow area.

Slot machine

Last month's other oddity, the Slot Machine, is still going strong. We received many logs from various parts of the world and it is clear that the signal comes from East Asia. I would be grateful if someone in that area could DF the signal.

S30, the PIP

Still active on two frequencies; 5448 and 3756 kHz.

Squeaky wheel

The unid marker that sounds like a Squeaky Wheel uses two frequencies 5461.5 and 3815 kHz. The signal comes from Russia and is probably a military station just like the Pip.
