The following is a list of '6 second ditter' signals I have copied today; Sept 26, 2019 Time Started listening: 1900 utc. :
6225 khz , 6750 khz , 6850 khz , 7700 khz, 8275 khz, 8700 khz, 8975 khz, 9050 khz, 9225 khz, 10525 khz, 11025 khz, 11150 khz, 11200 khz, 11525 khz,
11550 khz, 12000 khz, 12025 khz, 12500 khz, 13200 khz, 13400 khz, 13875 khz, 14400 khz, 14700 khz, 15100 khz.
All frequencies listed are at zero beat, in order to hear the 'dit' you will have to tune a bit higher in frequency or lower in frequency :-)
This is by no means a complete listing but it is only the stations I heard at my station as I am fairly sure there were many more.
Here's an extra, at least for me; The ditter on 9225 khz had another ditter on frequency, much weaker and at a different timing rate. I made a recording of it and use some noise reducing software to make the audio clearer and it appears about one second before the louder signal or if you like about 5 seconds after the louder signal. :-) Obviously 2 different signal sources... I haven't heard this before but maybe others have. I still believe this is some sort of propagation tool but I have no information as to who or whom is doing this... The mystery continues :-)
Hope you find this useful.

This is what I often call the "Pips Network". Yes, there are typically two sources in operation, and sometimes, fairly commonly, you can find one or more frequencies with both sources active on it.
Here is a table of some past activity, sorry, I really need to update this, and have not in several years:
