Chris,
Seems to be active most days but frequencies and times vary.
I haven't had too much luck lately, just a matter of not being in the right place at the right time.
Of late, there have been reports on the amateur 17m and 20m bands and I have found activity on 12Mhz between about 12200 kHz and 12450 kHz as well as on 8Mhz between about 8200 kHz and 8400 kHz - those frequencies are approximate.
Additionally, it has been noted frequently on the amateur 30m band as well as 40m and for a time I finding between 6 and 7Mhz but I haven't found it there in quite some time.
So far, no reports of it about 17m or below 6Mhz.
There is still a tendency for the signal be use frequencies of 5 kHz steps i.e. 14250, 14255, 14260, 14265 (etc) and those are the carrier frequencies and you would (of course) need to tune off by 1 to 2 kHz plus or minus for USB or LSB and your preferred "tone" or beat frequency if you prefer.
The signal does jump around alot. I hesitate to say "hop" as that would imply a for knowledge and implication that the signal was frequency hopping in some predetermined order. It likely is but after spending much time watching the PIPS jump around in the waterfall of a SDR, I cannot say with any certainty that there is an obvious pattern of any rhyme or reason. However, perhaps I am just not seeing the obvious and I may just be to closed minded and can't see the forest for the trees as it were.
It has been noted that the signal may remain on one frequency for extended periods of time as well, sometimes minutes, 10's of minutes, even more than an hour.
Good hunting.
cheers, Graham
