Can hear them here in KH6 land, at least the 3500.9 and 3501.6.
Merv K9FD/KH6
3501.6 is SE of me.
3500.9 is definitely NW of me and strongest of the three.

Well, most all the guys in New England see it peaking pretty much due south
- which suggests that the origin is off-shore in the Atlantic, rather than
on shore in the Carolinas. (Maybe from the "Bermuda Triangle"? :-))
How long have you had that Hi-Z 3-element receive array, Paul?

Paul and Gang,
Based on Pauls heading and a few other headings that intersect Pauls
heading, it looks like the signal is originating from the lower half of NC,
or the NE part of SC that touches NC.
Hard to describe, but an area like Fayetteville NC to the North, Wilmington
NC to the South East, and Myrtle Beach SC to the South (maybe as far South
as Georgetown or Charleston SC if I stretch things a bit). Still need a
few more data points, but the above describes the general area unless it is
out in the ocean.
Lots of headings that don't intersect Pauls heading which I had to ignore.

A rough azimuth from W4ZV in NC would be helpful ,
and from Florida

I think I can do a little better on estimating the direction (better
than SE which I gave earlier). I can get two 30 dB nulls out of my
receiving antenna by switching directions. Those nulls appear at 145
and 133 degrees. Pointed SW the signal is S9 this morning. In the null
at 133 degrees the signal is S0 and not audiable. The signal is
considerably stronger at the 145 degree null. So my best guess is 133
degrees from Decatur, Alabama (north central Alabama).
Oh! As I was typing this, at 1353 UTC the signal on 3501.6 abruptly
stopped. It was still at S9 just before it stopped. Then at 1355 UTC
it came back but with RTTY for about 15 or 20 seconds, and then back
into its continuous unmodulated carrier mode at S9. The RTTY burst was
too fast for me to boot an RTTY decoder to see if I could copy
anything. I suspect this is not an unintentional radiator.
There is very little QSB on this signal. I was waiting to see if the
signal amplitude was going to go down after sunrise. At 2 hours after
sunrise it's starting to show signs of QSB. It went down to S4 but now
its back up to S8. Now at 3 hours after sunrise it's S7 with QSB on my
vertical, but only about S1 on my low dipole.
A line of 133 degrees from my location goes thru Jacksonville, Fl and
also thru that long chain of islands, Nassau Bahamas, Turks and Caicos,
and Haiti and Dominican Republic. Most of Cuba would hit my 145 degree
null, but Guantanamo is close enough to be a candidate (with a little
measurement error).
A measurement from Florida would be interesting.

I'm mapping the data, but nothing to hang my hat on at this time. The data
from Steve (KK7UV) does not intersect any of the other reports (odd). A
heading from W8JI or AA1K would be very helpful.
Don (wd8dsb)
If you guys will remember from a year ago, Don is the man who pinpoints these
sources, if given a few more, reliable, data points. What is needed are
reports from directional loops. 2-3 feet in diameter are fine for getting a
sharp null, of a few degrees. This is much, much better data than from
Beverages, etc.
I built a loop with $5 worth of pvc pipe, and a bcb variable capacitor, and it
took about an hour to glue together.
I'm only hearing it S3 here in NJ at 10 am with a dipole, so doubt that my loop
is going to hear it in daytime.
Don - if it's in the direction you indicated (128 degrees) that puts in at the
southern tip of WV or center of NC. Doubtful that any weak source is going to
be audible to me this time of day from there. I'll do my best to get a bearing
on it tonight if it gets louder.

That's good information, Jerry!
What we need, rather than relying on antenna patterns for direction, is
direct phase measurement between a pair of vertical elements - with a third
element (or a pair) to resolve F/B ambiguity) if well calibrated , such an
array can be quite good for direction-finding measurements -but a good bit
of engineering is required to do the phase measurement. I worked on an array
like that for VHF marine radio years ago - worked quite well -mounted on
boats and Coast Guard cutters. Then what we would need to pin down the
origin would be at least 2-3 of such arrays at more or less right angles to
the source for good triangulation. When I'm not so busy, perhaps I can do
some design work on the phase measurement. Best approach is a system that
commutates digitally between the antennas to compare phase.
