Alberta lack of TPs for 25 March 2017  View Printable Version 
Sunday, March 26 2017

IRCA
That is indeed 1584 North Korea. And we still haven't the freaking foggiest
idea what exactly they are jamming, though it wouldn't be the first time.
The jammer is an older style analogue noise maker (as opposed to 819's
digital jammer during their off-air hours, which isn't the norm) and it is
turned off manually (which is the norm) just after 1am every morning.

I believe they're attempting to jam Harbin, which happens to turn off around
that time, but it doesn't account for the Korean programming on the
much-wider more widespread 1476 network out of Harbin, with multiple
repeaters that get out well into Seoul. The jammer is not especially strong
in Seoul, but it's persistent and likely based in the Pyongyang suburbs with
972 and a few of the other weaker ones. It's either rather distant, such as
in the northern border areas of North Korea (if jamming Harbin) or it has
low power. I believe the first of the two if it's being heard overseas at
all. It clocks in at 30dBu in Seoul, just above the noise level but strong
enough that it's heard 100% of the time it's on-air and largely covers the
two 1kw KBS signals in the south (of which I do not believe the North is
targeting due to their low power and distance).

It can have some interesting patterns on the SDR as well:

Naturally, this one along with all the jammers (new and old) and stations
are in my own publication and audio documentary, making it hard to find an
excuse to not know about it *wink*.

I think the bubble jamming is from North Korea. Heard sometimes weak
also here in Finland.

73 from still snowy eastern Finland,

Very nice Asian reception into Masset this morning. Highlight was 1584
with

bubble jamming. ? Iran, cochannel 100w NHK 1 often at good level. Not a
peep from DU and a modest post LSR enhancement. Indonesia on 90 and 60
meters exceptionally well heard. 73, from a sunny Queen Charlotte. Walt

Hi Mike,
I identified you because you were with us on some these catches.

Hi Todd,

As one referred to in your comments, I would defer to Neil on this one.
Unless you can ID something about the signal, the music, language,
station ID, or other identifiable characteristic it is best to err on
the side of caution, and not claim it. Another way would be direction
finding, but with skywave propagation anomalies this is not necessarily
a sure bet.

73 to all,

Mike Bates

I think one has to take a couple of things into account here. First is that the majority of us on this list ( or any list for that matter ) don't know what DX is like from your location. Second is that some tend to apply their own "DX standards" to everyone else. Therefore there are always going to be those who doubt a reception.


Another factor is what details a DX'er provides. Not infrequently the way a DX'er words their report can open the door to doubters. And the first thing in that list is how reporting of a het is worded.


At one time or another, probably most of us on this list have doubted others' logs or have been doubted ourselves. It comes with the territory. A DX'er has to establish their own criteria and to DX for themselves in that sense.

Hi Todd,

As one referred to in your comments, I would defer to Neil on this one.
Unless you can ID something about the signal, the music, language, station
ID, or other identifiable characteristic it is best to err on the side of
caution, and not claim it. Another way would be direction finding, but with
skywave propagation anomalies this is not necessarily a sure bet.

73 to all,
