Babies at play as seen on the P3

Some months back I thought I saw some
words on the SVGA output from the K3. So
here I hear A73A calling in the contest
and obscuring his signal was some bad QRM.
I can't tell exactly where it is coming
from but it seems like towards EU was
strongest.

It did not display on the P3 but the SVGA
is much slower and shows longer capture
and taking a photo of the the monitor, the
print came out clearly. With the HI-Z 8
Pro I was able to notch it almost
completely out (95% out) but here's what
it looks like.

What are the children doing?

It's been going on for a long time
tonight.

Re: Babies at play as seen on the P3

Many ops use the video feature of Fldigion some modes. On one Navy MARS
freq, when we changed modes, everyone TXing would post pre-video for a
few transmissions.

When you switch from Thor to MFSK to etc, etc, etc. it is best to tell
the other net ops what's up. Conditions do change. This is normal.

It looks like Digital SSTV. There is a “text” mode in a DRM SSTV app called Easypal (and maybe others), that sends brief text messages in the waterfall.

I’ve seen this show up from time to time, but was certainly curious the first time I saw text on my P3 screen :-)

The "babies at play" are a group of SSTV operators who think they own a
certain piece of 20M SSB. If you dare to call CQ there, even when it's
empty and after asking if the frequency is in use, you'll be bombarded
by their transmitters running as much power as they can, intentionally
interfering with you.

Re: Babies at play as seen on the P3

Sounds like what happens almost anywhere on the bands if you call cq in AM. Apparently all frequencies are now “owned” :-)

Re: Babies at play as seen on the P3

In reply to this post by Jim Brown-10

I had only once before maybe a year ago
seen what I thought were words on the SVGA
and I thought someone went to long lengths
to write software to QRM.

If you look at the frequency on the
monitor from the P3, this interference was
7.065 or so and it was constantly being
resent every minute or so.

The HI-Z circle 8 notched them out
essentially completely. I aimed it towards
them to have the words appear brightly for
the photo.

What a group of spoiled children. I
haven't seen this intentional QRM before
and had no idea what the P3 was revealing.

Re: Babies at play as seen on the P3

the ones I can't figure out are the key down and then sweep across the band
with their VFO knob. I have bee seeing them since I had a soft rock pan
display and now on the P3. They are almost continuous. they stop
occasionally to QRM a QSO and then keep going.

Re: Babies at play as seen on the P3

Maybe "sweeping" for checking antenna SWR .... or "memory tuning'' of PA's
and antenna tuners, as Elecraft units do. (;-)

Re: Babies at play as seen on the P3

There are ionospheric chirp sweepers that go through the hf spectrum
every couple of minutes. They sound like someone lightly clearing his
throat. Have no idea what it looks like on the pan display. On a given
frequency you'll hear the chirp at the exact same time every couple of
minutes

Re: Babies at play as seen on the P3

Interesting. These are RF peaks, that move across the 1.8 to 2 MHz band,
for instance. They often stop on QSOs in progress, or flow thru them,
sometimes reverse, may disappear, may take off in either direction. I
assumed they are human caused. ???

Re: Babies at play as seen on the P3

The sweep I was referring to I've been hearing for years, anywhere
between 2 thru 9 MHz. Never heard it higher than that, I think.

According to my notes last summer you could often hear the short chirp
on 40m close to the ODD minute. It sounded like a raspy Morse "H". The
sweep rate would accelerate from approx 50 kHz/s at the low end to 200
kHz/s up near 8 MHz.

(I used to log all that kind of stuff as an SWL: "Giant Step, Giant
Step, this is Retail. Do not Answer...")

In reply to this post by Leroy

I see a lot of sweepers, which are in reality Ionosonds. The way to
tell, is if they cover a very wide range, and they sweep at the same
speed, they are probably probing the ionosphere. There are a LOT of
them sweeping the 40 meter band.
