[AMRadio] FCC cites Jammers

[Dave Harmon]

Hi Don....
I was listening last night to you and some other guys on the bench
receiver....mebby it was night before last, anyway after everyone signed off
I was so involved in the project that I didn't turn off the receiver.
That rushing sound continued with no letup for hours even thought there was
no amateur stations on freq.
So....you are probably correct about those stations being in Europe.
There is another jammer that uses a sweep generator to swish his carrier
back and forth.
This station is extremely loud here.....

A couple of nights ago a strong AM signal was playing music on 3885.  Maybe 
that's what he was referring to.

I also heard the same on 160 about a week ago.  First on 1870 or 
thereabouts, and the next night on 1890.

There was a SSB QSO on 1890 at the time.  Not sure who was on first, but I 
answered a CQ on 1885 and carried on an AM QSO for about a half hour. 
Apparently, the music station closed down just about the same time I fired 
up, and the SSB stations were totally convinced that I was the one doing the

transmitting.  I heard a weak SSB voice in the background, zero-beat with 
our frequency make the unidentified remark over the other AM station, "now I

know who it is".  I briefly tuned back up to 1890 and the music station was 
gone. After we ended our QSO I tuned back up the band and the stations in 
the SSB QSO were  still talking about it.

Let them think it was from my station if they wish.  It's their problem not 
mine, since I was already in QSO down the band while the music was still 
playing.

BTW, another strange signal I have been hearing lately on about 3885 is some

kind of rushing noise, about a half second in duration.  One night there 
seemed to be two signals, one much weaker than the other, and they seemed to

be taking turns transmitting, "talking" to each other.  Could be two 
stations exchanging information using some kind of digital data burst . 
Probably legitimate, from Europe, since their ham band  stops at 3800, and 
over there, 3800-3950 is allocated the "Fixed/Mobile" service.

I tend to avoid 3870-90 during prime evening hours.  Too much chaos and 
congestion, and the QSOs tend to evolve into huge round-tables.  Instead, I 
hang out around 3700 +/- QRM and where I hear another AM station.  I don't 
care for the big round tables.  "When the count gets up to four, that's the 
time to hit the door." I'll just QSY and start another AM QSO elsewhere in 
the band.  That makes for less QRM, shorter waits between transmissions and 
best of all, more AM presence on the band.
