Re: Topband: NCC-2 antenna pattern?

[Jim Clymer]

Come on, JC...
Even I know, YOU know what K9YC is talking about! After living in IN for 15
years, CA for 34 years, and VA for 10 years, with essentially the same
station setup, over the long term, for success on TB, QTH is paramount.
(detuned TX antennas notwithstanding)

Re: Topband: VK6GX in the Spring Stew

[Jim Clymer]

Phil called me on Sunday morning (local) just a bit after my SR. I kept
getting "6GX" and then got the "V." There was just too much QRN and QSB for
my little RX antenna to pull it through. Sorry Phil!!
I was running 100 Watts to an Inv-L.

Topband: Warning: OT!

[Jim Clymer]

I completed a CREI course - BET (Bachelor of Engineering Technology). CREI,
stood for Capitol Radio Engineering Institute, a division of McGraw Hill.
Before that I received a diploma in Broadcast Engineering from  CIE,
Cleveland Institute of Electronics.
At the time I was working for Crown International, Elkhart, IN.
Must have been at least 150 years ago!

Topband: Question about on ground radials field.

[Jim Clymer]

Hello Gang,
This is somewhat related to the "Will radials on ground help?" thread. I
have poked around in various discussion groups but haven't found a specific
answer.
Assuming I have a fairly decent radial system on the ground (60 radials of
various lengths, some longer than 1/4 wave, many shorter), what happens if
I elevate the feedpoint of a quarter-wave, base-fed vertical? Let's say I
have an aluminum mounting post properly bonded to the radial plate, the top
of which will serve as the "radial system" connection for the vertical. Is
there some fractional part of a wavelength that the feedpoint could be
raised and not lose the effectiveness of the on ground radial system?
Thanks, and HNY to all!

Re: Topband: CQWW Condx on 160 a Bust

[Jim Clymer]

When I toured 160 on Friday evening (local) I was dismayed at what seemed
like a very high atmospheric noise. I thought, "This is as bad as it gets!"
Not so! Saturday evening was even worse!
However, in truth, condx have been hot and cold the past week or so.
Recently I was able to work 10 or 12 EU one night, but couldn't do squat
the next. To wit: With OK1CF boiling in one night last week, I couldn't get
his attention with the full legal limit. Then last evening he was much
weaker, and he heard me the first time I called with 50 Watts.
One thing I've learned in the 40 years of hard labor on 160, every time I
tune the radio to 1.8 mHz., I expect to eat a hugh slice of humility pie.
That's why I keep the little refrigerator near my ham desk.
GL this weekend!

Re: Topband: Condx for Stew Perry!

[Jim Clymer]

Hi Bob,
You may have missed one important detail. In 2014 I moved to NW Rockingham
County, Virginia.
However, during my 30+ years on topband from my small city lot in Fresno, I
worked 186 countries. One glorious evening in February - can't remember the
year - I worked 17 EU.
It took me until November of this year to beat that record, when I worked
19 EU the first evening of CQWW CW.
So the 33 EU in one evening this weekend is pretty amazing for my little
peanut whistle Inv-L!!
73,

Re: Topband: Speaking of Noises...

[Jim Clymer]

Tim, Bill, thanks for posting the files. FWIW: I'm hearing it this evening
on both 80 and 160. The sounds on both bands are essentially identical --
as far as this tired old audio engineer can discern.
Now the kicker... in real time they sound almost nothing like the recording
Tim forwarded. Perhaps if I slowed the playback to about 1/4 speed it would
be closer. Still am hearing only 4 pulses.
Next step is to listen with a wide bandwidth.
Thanks all.

Re: Topband: Formula

[Jim Clymer]

Do you have an antenna analyzer that measures the inductive reactance? That
would be the easiest approach.

Today's
Date: Sun, 10 Dec 2017 16:05:53 -0500
From: "Gary Smith" 

I just installed a replacement wire for
the 160 sloper. I made it 129' as was the
earlier one that came down in the winds. I
have to use a spud gun to get fishing line
over the tree tops and where the spud
lands, I connect the wire to the eye
fastener & reel it to the radial plate.
This time I had to use a different tree as
the earlier one came down in the last
hurricane.

Now it is resonant at 1.785 and it is not
a problem at the lower end of 160 but
higher up it is. My problem is compounded
in that I also use this antenna for 10M,
12M and the upper part of 15M. I need to
shorten it for use on these as well.

It is too far away to shorten the wire and
solder a new eye on it and now it is too
cold to play with it on the tree (have
difficulty walking right now). So being
too long, capacitance at the feed point
might be my best answer. I have several
fixed vacuum & doorknob capacitors of
small pF to choose from that I can put in
line. Is there a formula that I might plug
data into to come up with the needed pF?

Thanks & 73,

Gary
