Followup.
The pulse sent this time is the same as used Aug 26, 2013, Aug 03, 2013, Aug 02, 2013, Jul 28, 2013, and Jun 14, 2013. It is a ~0.125 sec pulse sent every 6.0 seconds.
The frequencies used appear to be roughly the same list as those days also, allowing for some differences in what I could receive for propagation and QRM. Some of the frequencies are in or under other signals.
After having gone over the spectrum recoprdings I have 11 more pulses / frequencies to add to the list I posted yesterday, this brings the total seen yesterday to 48. Based on the 0.125 sec pulse sent every 6 seconds there are up to 48 possible pulses and frequencies in each network. It would be tempting to say 48 is possible and I found 48, so that is all of them, but in reality I can tell there are 2 networks in uses in my recordings from yesterday (and almost every time Pips has been seen). This means there are 96 possible pulses / frequencies. We know that some frequencies are common to both networks, for example yesterday, as many times when this is seen, 11150 kHz had pulses from two different networks. This means if every possible pulse is sent that the frequency list should be something less than 96 frequencies total, or 96 minus the number of double pulse freqs.
