[CQ-Contest] 160 NOISE

[Michael Tope]

Bob,

I have no experience with the MFJ, but I can tell you that
the JPS noise canceller (ANC-4) works quite well for single
noise sources. I used a low 40 meter inverted-vee (~20' high)
at my qth in Florida to null an S-9 noise source on 160 down
to the S-1 level. The only trouble I had with the ANC-4 was BC 
band overload of the noise antenna port (this signal path contains 
a wideband pre-amp). A BC band high pass filter solved this 
problem quite nicely.

Good Luck,

Mike, W4EF...........

My vertically polarized 160 antenna picks up 30-40 dB noise from some
local buzz saw around here.
That is what I weeded through last night.

I have seen several posted questions concerning some of the JPS and MFJ
noise cancelling products out there from people with a similar problem.
I have also seen promises to post real life experiences that potential
users were going to pass on to the reflector after getting one of these
devices. To date, I guess I have managed to miss these "results" postings.

Will somebody out there who has one of these things please tell me how
well/poorly it works for you??
Hearing nothing, I'll spend my money, but for which product?

BTW,
There is an 8 lander up there that insisted on telling me last night
that we had worked before, when I called him around 1215 GMT.
My responses of "NO NO NO" was an attempt on my part to tell him that
he was not in my log.
I'm sorry that he insisted on responding to my calls and my "NO NO NO"
with his repeatedly hitting F6. 
He's not in my log, and I really did want him in my log.

THAT VERY WONDERFUL  ADVICE GIVEN OUT ON THIS CONTEST REFLECTOR SO MANY
TIMES BEFORE IS ADVICE WELL TAKEN.......................
WHEN SOMEBODY CALLS YOU ................WORK 'EM !! 
DON'T TELL YOU'VE  ALREADY HAVE WORKED 'EM,
'CUZ YOU MIGHT ONLY "THINK" YOU'VE WORKED 'EM.

Only one of many good reasons to subscribe to this list.
