Pips network of ditters is up again today, on many freqs.  At 1413 UTC I noticed it was up in the 0.125 x 6.0 second format, no idea how long it was up before I noticed.

This set was up form before 1413 to 1512 UTC, Dec 06, 2015.

Early list of freqs, as usual there were 2 sets up:
4900
5225
5450
5575
6225
6550
6725
6750
7700
8275
8825
8975
9050
9225
10050
11025
11150
11225
11300
12025
13250
13325
13875
14400
15100
15550
15625
16000
16725
17475
17650  B
17950  B
17975
18025
18100  B
18625
19300

Frequencies with no letter all belong to one set of frequencies, frequencies followed by a "B" are the second set.  There are 34 frequencies on this list in the first set, however the 0.125 second pulse every 6.0 seconds allows for 48 possible frequencies.  I can confirm that every freq in the 4900 to 19300 kHz range is accounted for, by monitoring any given freq and the one below and above you can tell if you missed a frequency.  I have used this technique to find frequencies I missed at first that were buried under another signal.  So potentially 14 frequencies in the first set are unfound, they would have to be above 19300 kHz or below 4900 kHz.  Because of how strong the 19300 kHz signal was, and how weak the 4900 kHz signal was I strongly suspect the missing freqs are all below 4900 kHz and were unheard because of propagation.
