UNID pip 6370 kHz (carrier frequency) active

Tuned in at 2018-05-20 23:45

still going 2018-05-21 00:10

steady one PPS with what sounds like occasional missing pips but no noticeable pattern to when the missing pips occur

Signal strength is very strong in Eastern Ontario near Ottawa.

cheers, Graham near ottawa Canada

Not quite as strong as it was two hours ago.

WWV on 5 MHz is increasing in strength as evening propagation changes, WWV on 10MHz is fading away.

conditions are not too bad this evening. RWM on 4996 kHz and on 9996 kHz are both audible but weak with QSB this evening.

Based on those observations I would guess the UNID PIP is somewhere in North America and West or South of my location.

Just checked this morning and this UNID 1 PPS PIP is still active.

Signal strength is about S3 in Eastern Ontario near Ottawa Canada

WWV on 5.0 MHz is a bit stronger

This signal has been pip'ing away all day.

I took some time this morning to take some measurements on the signal.

Pulse width is approximately 16ms - measured multiple times between 16 and 16.6 ms, depends on what you consider the start and finish. Most consistent results were using my FT-950, AGC off, NB off, bandwidth 2400hz, IPO on (preamp OFF), and in AM mode. (first image).

Assuming the UNID PIP is synced to UTC and using my GPSDO as my local reference were it's 1 PPS was fed into the receiver antenna I measured a delta T of 4.760 ms.  Again, assuming the UNID PIP is synced to UTC that would give a range of approximately 1427 km or  770 nm. Methodology as to receiver settings as noted above (second picture)

I plotted the 1427km on google earth but the image to large to include with this post so it will be in a following post.

Part 3 - google earth range ring of 1427 km and some additional comments

Note - that 1427km was NOT corrected for a reflection off of the ionosphere so is likely a bit long.

For what it's worth, while monitoring this morning I listened for this signal on a number of online SDR's throughout North America and in Europe.

As expected I did not hear this signal on any overseas online SDR. Of those in North America, the strongest signals were noted on those located in Eastern US - up to about S9.  Texas was moderate at around S5, nothing heard in California but it was audible on Token's SDR in the Mojave desert and audible as well in Alberta, not very strong but audible.

This signal's characteristics are the same as what was being reported on the amateur 40m, 30m, 20m and 17m bands. Perhaps whatever this is has finally set up on this frequency and will continue ???

Now, if we could get a couple of other good TOA measurements from Western and Southern North America we could pin it down a bit better.

0102 UTC - I started monitoring the PIP at 0051 UTC and the signal was S7-S9, suddenly at 0102 it jumped from S9 to S9+10dB to +20db in WNY.
0106UTC - Signal is now S9 to S9+10db. Static crashes are getting stronger as the storms are moving into WNY tonight.
0113 UTC - Signal back up to S9+20db.
0125 UTC - Signal strength varies from S9 to S9+20db to S9+40db. Checked web SDR in Waller County TX and signal was S7.
0347 UTC - PIP signal S9 to S9+10dB to +20db.
1412 UTC - Checking this AM, PIP signal is S3-S5.

Still going strong pip'ing away.

Signal has been strong since I started to monitor this evening around 2018-05-22 21:30 UTC and was likely active all day but that is just a guess.

Currently at 23:25UTC about S9 in Eastern Ontario near Ottawa.

UNID PIP 40m 0224 UTC 24 May 2018
« Reply #40 on: May 24, 2018, 0230 UTC »
Been monitoring the UNID PIP on 40 meters since 0200 and it has been pulsing continuously on the following frequencies. 7120, 7130, 7165, 7170, 7180, 7205, 7210, 7265, 7290. 7300 kHz.
Signal is s9+20 to S9+40db. in WNY. PIP only pulses a few times on each frequency before changing to one of the other frequencies listed.
Checked back at 0311 UTC and PIP is gone.

Interesting.

I was monitoring 6370kHz for the UNID PIP which had been operating there for a several days while at the same time searching from about 15MHz down (or up if you think of wavelength) to 4MHz for the same or similar signal including the "Ditter network" but I stopped listening around 00:30. I will have to listen a later tonight.

If this is the same signal that was on 6370kHz it is interesting that it has usually been noted on the amateur 40m/30m bands and occasionally on 20m and also 17m. 6370kHz being unusual in that it is not also an amateur assignment.

Of note, I have also not noted the "Ditter network" i.e. dits every 3 seconds in some time. I am guessing the two activities are not related but they might - truth is often times stranger than fiction.

A wide bandwidth SDR waterfall sure makes it easy to scan broad swaths of frequencies quickly. Much easier than the "good old days" of slowly tuning a receiver through many MHz's looking for something.

UNID PIP 8120 0138 UTC 25 May 2018
« Reply #43 on: May 25, 2018, 0141 UTC »
Just noticed UNID PIP pulsing on frequencies 8115, 8120, 8125, 8135, 8140, 8145, 8150, 8155, 8160, 8165. 8175, 8180. Signal S9+ 20dB to S9+40dB in WNY.
One pulse per second and the amount of pulses for a frequency is random.
0153 UTC - Still going, noticed some pulses are S9+60dB in WNY.
0203 UTC - PIP still going.
0215 UTC - PIP still going, jumping around frequencies at random.
0253 UTC - PIP still going, jumping around frequencies at random.
