Pips Network? 1909 UTC 16 Nov 2016
« on: November 16, 2016, 1910 UTC »
Thanks to Token for the tip, hearing long dashes on many of the regular Pips frequencies, such as 11150, 14400, 18625, etc. About a second long, and about a 50 second period.

This set of signals was up from before 1815 UTC to 2033 UTC, 16 November, 2016.

I was not able to access HFU to post yesterday, so will add info today.

In this case the CW dash was 1.0 second long, and the dash happened about every 51.625'ish seconds.  When I first saw it on 11150 kHz I did not think it was the Pips network, as I have never seen that system use anything like that repetition interval, the previous longest interval was 10.5 seconds.  Intervals of 3.0 to 10.5 have been seen and recorded.

However, after finding a few more frequencies in use, confirming that those frequencies were indeed past used Pips freqs, and confirming that the frequencies are being sequenced just as all past Pips freqs are, I decided it was probably the Pips network, just with an interval much longer than we have seen before.

I made wideband recordings that I have yet to review, so the frequency list is probably larger than below.

(edit after recording review) Frequencies seen so far:

11150
11200
11550
12025
13200
13400
13875
14400
15100
15625
16000
16725
17475
17775
18025
18625
19300

That should be a complete list from 11150 to 19300 based on checking each pulse as it sequenced on the recording.  However the spacing allows for a lot more freqs, so I assume there are freqs below 11150 and possibly above 19300 that I could not receive.
