[SCCC] 20M jamming

[k6xt]

First off apologies for not changing the Subject line in my email below.

Second my apologies to the Amateur Auxiliary which, after reading about 
it at arrl.org, I discovered is what official observers used to be. N1ND 
forwarded to them because they're the responsible ARRL department.

As of now 1830Z Friday 1Feb19 the jammer has not reappeared. This may be 
a net that meets only early AM we'll see. I'm back to thinking its an 
Air Force MARS group.

Hello to Steve WV1X hope you can help us rid 20M CW of this jammer.

I sure can. Direction is NE from me too. I may have it identified. This 
morning I noticed there is a group of traffic handlers on 13993kHz USB 
at the time the jamming is active. So I listened in. They are using MARS 
type callsigns like:

J, S, 8DG, A, 7PH, D, High Card Golf, High Card Romeo, High card Juliet, 
8S, S9 and some others. High Card Romeo was identified as a NCS. Many of 
these, the one-two-three letter calls, apparently are abbreviations. 
During my listening it appears that 7PH was further identified as AAR7PH.

A few days ago I sent a question to Dan N1ND the ARRL regulations guy 
asking if he knew about the "jamming on 14000-140035. Here's his reply 
to me:

Hi Art

I am sending this on to the person who works with the Amateur Auxiliary 
who would be the go to person on this...

 From which I assume the culprit is a "Amateur Auxiliary" member.

A signal duplicating the jammer inside 20M appears on 13993 when those 
folks have traffic to exchange. They coordinate the net by voice, pass 
traffic with that digital signal. The net often refers to "ALE" which I 
assume is one of the forest of digital modulations.

I sent another email to N1ND today summarizing my findings of this 
morning, and offering to send a K3/P3 screenshot plus audio recording. 
We'll see what happens next, which could be no response. I can envision 
the miscreant slinking off of 20M never to be heard again, and that's 
our resolution.
