Re: [IRCA] KCKN-1020 New Mexico test heard in Massachusetts

Hi Mark--

Thank you for the interesting post. It seems most of the northern folks 
in #MWDX were having significant co-channel issues with Reloj in the 
null of KDKA last night, but I think most ended up getting good copy of 
at least the sweeps and code. Luckily, Reloj was never an issue for me 
here in Memphis.

I initially tried to simply null KDKA with the Wellbrook ALA-330S loop, 
but NNE null on KDKA also pushed KCKN down too much. I fired up the 
DXP-5A phaser to phase the Wellbrook against a MFJ-1024 active whip, 
which cleaned things up rather nicely. I also have a local slopper a few 
miles from this QTH, Spanish broadcaster WGSF-1030, which fortunately 
wasn't much of an issue during the test.

I used the outstanding Winradio G313e IF recording feature to record the 
entire 1010-1030 kHz spectrum from 0559-0724 UTC. This allows me to 
record session to the pc hard drive and then to play back the session 
and use the entire range of G313 features to demodulate all signals with 
the 20 kHz bandwidth for best reception. During my initial play-back of 
the recording this morning, I found that I could tweak the signal for 
even better readability than my "live" session last night. This is a 
very impressive feature of the G313, now I only wish I could an even 
wider spectrum, like 50 kHz. I will go through the session this evening 
and record some of the best parts with Total Recorder, then convert them 
to .WAV tracks and burn to CD to include with my snail mail report.

This is NM #2 for me, my records show I have a KPAR-1190 Albuquerque qsl 
around here from March 20, 1978, which if memory serves was also 
courtesy of a DX test, but I did not see the QSL. I know it has to be 
here somewhere, gotta dig deeper. =)

Thanks to the good folks at KCKN who coordinated this maintenance test 
the the DX community, special thanks and huge kudos to Les for his 
outstanding efforts.
