Title: PIPs / Ditter active on 6720, 6820, and 6920 kHz
Post by: GC on May 02, 2018, 2328 UTC
hearing the ditter on 6720, 6820, and 6920 kHz  100kHz offset from each other but I haven't looked either higher or lower yet.

Signal strength is strong in Eastern Ontario.

So far I have not heard any "double" pulses and I am starting to look above and below these three frequencies

Should have also mentioned that I can hear these same pips on these same freuquencies on online SDR's in Pennsylvania and Alberta Canada

cheers, Graham

From that freq set, for doubles try 10990 kHz and 12010 kHz.

Indeed, double pips heard on 10990 and 12010 kHz - very weak but identifiable.

0049 UTC - Hearing the PIPs on 10990 in CW mode, very weak, no perceptible signal on the panadapter.
0052 UTC - Hearing the PIPs on 12010 in CW mode, very weak but a bit stronger in tone than 10990, no perceptible signal on the panadapter.

Using an indoor magnetic loop & TS-520SE. The bearing (nulls) on 7020, 7130 & 7460 appear to be due N-S from western NC. Strong signal, had to use attenuator to get a null.

The Pips Network has changed frequency sets at least three times tonight.  I started monitoring at 0005z and that was set #1, set #2 started at 0042z, and set #3 started at 0131z.  There may have been more changes than that, I will have to check the recordings, but those were the very obvious ones.

If someone can grab a time after UTC second on any one of these (and mention time and freq used) it might help narrow down the location.  The primary set I am hearing here is 11.8 msec after the UTC second.  I have not tried to grab the weaker set yet.
