Hi Art,
Whether or not elevated radials would help K5P, what you stated is NOT
pure
speculation! :-)
Generally speaking, it is well-established that we can use far fewer
elevated radials under a vertical than ground mounted radials, for the
same
efficiency.

Hi Lou,
Of all the sources of unique help and info about 160 meters, IMO this
reflector is the best one.
I suppose you've found the searchable archives, which I've found
invaluable
many times:
lists.contesting.com/archives//html/Topband/
lists.contesting.com/archives//cgi-bin/namazu.cgi?idxname=Topband
There are other sources, notably ON4UN's Low Band DXing, published by the
ARRL. Everyone with an interest in 160m should own a copy.
There are a number of other informative web sites out there, too. I have
some of them listed and linked to from www.w0btu.com (not all on one page,
sorry). And there's a page there about Beverage antennas there that you
might find useful.
Maybe you would let me pick your brain sometime about my swamped-grid
dual-833C legal limit amp. It works fine on 160 and 80, but it needs
neutralizing if it's going to be stable on 40 (and work at all on 20). I
have a plan to neutralize it using a tertiary winding on the input
transformer, but I foresee a lot of trial and error. But I don't have time
to work on that right now.
I wasn't even sure if two of those triodes in parallel would even work, so
I didn't spend a lot of time making it look pretty.

Stick around, Lou. Believe it or not, this is usually a friendly forum!

Thanks Doug.
Awesome read. Has me wondering about our guys on the island.
Maybe the "darkness" of the island has something to do with the S9+
signals we're seeing here in San Diego. Hi.

Dear OMs and Yls,
The following link was posted me by Don EI6IL and tells a very
interesting story of woe and murder on Palmyra Island going back to the
very
discovery of the atoll. Slightly off topic but many of us have
illusions
of working K5P so this may be of interest and also add a bit of spice.
The
cursed paradise is a good read:
http://mysteriousuniverse.org/2014/07/the-cursed-paradise-of-palmyra-atoll/
Yes EU feels the W6 pain this time and the poor cousins of EI in DL
and I lands are even worse off than in EI for K5P. At least the EI path
is
over ocean and tundra rather than thousands of fellow hams.
Good hunting.

Thanks Mike, I'm not going anywhere. I hope that Tom reconsiders his
leaving. If you look at the time and effort he spent on his website which
he always updates and adds to, and the efforts he puts forth on the
various reflectors you have to say it is nothing less than admirable. A
handful of people do such things and many of them are on here also. So I
agree, this is the place to be. I've know about this reflector for years
but never bothered with it since my interest in 160 was nil. Recently I
made a decision to give it a crack and boy do I see it is a whole lot
different than working even 80 meters and above. Lou W1QJ

Some auto tune linears are set up to change bands or sub-bands
by sending one dit. With peak reading meters, they will also
display RF out and SWR from one dit. At least this is a lot
less QRM than tuning up the old fashioned way. In both

Most rigs have IF gain this is optimized for phone, which
means it is way too low for CW. This results in an AGC

Short of redesigning the rig (I actually did this to an FT-757
by adding an IF gain stage), you should use an audio attenuator
in front of your headphones so the the rig's audio output stage
clips before the level in 'phones gets too high.

Hello,
Need your help. For a long time can't get working FCP for my Inverted L.
I'm looking for some way to check quality of my homemade isolation
transformer. I'm connect primary to 50 Ohm dummy load and secondary to
Antenna Analyzer. Get reading @1850 Ra=28 Ohm and Rx=34 Ohm. Rx is raised
with frequency. Inductance for primary and secondary is 5.7uH.
Capacitance
between primary and secondary is 140 pF.
These reading looks normal or somthing wrong ? I'm expected 1:1 impedance
transformation without additional Rx.
Thanks a lot in advance for your help.

A friend gave me some Commscope 1/2" heliax but had no connectors to

with connectors. It requires SFX-ANF for a N connector, they didn't
make one with a PL-259. Would anyone have two or four of these

Yesterday to my big surprise I could copy K5P on 160m for
about 30 minutes, seemed to peak around 1445Z. They where
as strong as 559 on the peaks with deep QSB. I never ever
was thinking it was possible to even hear them the way
160m is these days.
However they does not seem to RX very well. Me and OH6KN
and one or two others was calling but K5P mostly was calling
CQ.
Big problem also was that the K5P operator never did announce
the RX frequency, he seemed to listen both up and down.
I am sorry but this is a very bad way of operating.

Please do not think I am criticizing the team. So far at 17:27
GMT on
Jan16 there has only been one 160M QSO with zone 14 which includes EI, G,
DL
etc. The propagation gods are not favouring us at all. K5P is a hard
reach on most bands and once you go away from 17 through 40 meters there
are
literally only about five QSOs total on the other bands.
Some are losing their reason and making poor comments which
reflect
badly on both them and their nations. We as a hobby need to do better
in

1445Z is good propagation to western NA (west coast sunrise), so they
were probably listening there. If they knew there was propagation to EU,
they would probably have listened there instead. Let your pilot know.
Big problem also was that the K5P operator never did announce
the RX frequency, he seemed to listen both up and down.
I am sorry but this is a very bad way of operating.
They are very close to JA. JA can TX 1810 to 1825. K5P TX is 1825.5.
They listen DOWN for JA, UP for everyone else.

My take on it was that "the dit marks the spot" either for a buddy or just
as a "public service." While not as annoying as other forms of
transmissions on the DX freq, it still shows bad manners...however, not as
bad as when I forget to engage the split button. Maybe that is why I've
never been nominated for the A1 op award. At least it's why I wouldn't
nominate me.

Message-ID: <000d01d1512e$cef5dd60$6ce19820$@nbnet.nb.ca>
Content-Type: text/plain; charset="us-ascii"
Whoever the 160m op was this morning was doing a really great job, moving
right along at aprox 32-33wpm. (I have to wonder if it was K9CT)
I managed to get in the log at 1155z (10mins before SR here), however
there
were a few W1's and a VE1 that were worked 10-15mins before that.
What surprised me (why, I don't know-It just does, even after many
decades)
was when K5P would say AA0R? AA0R?, .WB2Z.'s, KB4Q.'s and VE7S..'s would
all
come back to him. Yes, most did stop calling, so I have to wonder...are
these folks just plain rude or were they not hearing K5P well enough to
discern who he was coming back to?
Now, In full disclosure, I am no saint, and have been known to respond to
a
DX stn if there's an unruly p/u I hear something like VE3A? VE3A? or 9AA?,
9AA? ,IT9A? IT9A? or VE8AU? VE8AU? or VE1AAA? VE1AAA? but all those dance
around my call (VE9AA). If there's any change "away" from my call, I stop
calling. I also listen to my xmit QRG and if there's someone with a
closer
call, I will stop calling. Luckily, it almost always starts off with VE9?
or 9AA? so I am good 99% of the time and rarely step on anyones toes. (and
always feel bad if I do)
If the DX said WB6Z? I certainly wouldn't call. Full credit to the K5P op
who tried to stick with it til he figured the original caller wasn't
hearing
him or they were getting pummeled so badly from calls not even close to
the
original, that he moved on. Rate is king when time is

gah !
Anyways, they were doing an incredible job despite incessant callers..some
of whom NEVER stopped calling. They were in here solid for a good hour at
about 529-549 (no preamp on), inverted L @ 35' a mile of radials..and up
to
26mins past SR here before slipping into the dust.
Well done Islanders ! Well done.

Mike, if you go to clublog.org, search K5P DXpedition log for your call,
and mouse over the greenie, you will see the operator for your QSO (his
call and picture). I don't think they've uploaded this morning's QSO's yet
but they are doing uploads several times a day.
W0GJ was the operator for my 160M QSO. Sharp looking guy!

Whoever the 160m op was this morning was doing a really great job, moving
right along at aprox 32-33wpm. (I have to wonder if it was K9CT)
I managed to get in the log at 1155z (10mins before SR here), however
there
were a few W1's and a VE1 that were worked 10-15mins before that.
What surprised me (why, I don't know-It just does, even after many
decades)
was when K5P would say AA0R? AA0R?, .WB2Z.'s, KB4Q.'s and VE7S..'s would
all
come back to him. Yes, most did stop calling, so I have to wonder...are
these folks just plain rude or were they not hearing K5P well enough to
discern who he was coming back to?
Now, In full disclosure, I am no saint, and have been known to respond to
a
DX stn if there's an unruly p/u I hear something like VE3A? VE3A? or
9AA?,
9AA? ,IT9A? IT9A? or VE8AU? VE8AU? or VE1AAA? VE1AAA? but all those dance
around my call (VE9AA). If there's any change "away" from my call, I stop
calling. I also listen to my xmit QRG and if there's someone with a
closer
call, I will stop calling. Luckily, it almost always starts off with
VE9?
or 9AA? so I am good 99% of the time and rarely step on anyones toes.
(and
always feel bad if I do)
If the DX said WB6Z? I certainly wouldn't call. Full credit to the K5P
op
who tried to stick with it til he figured the original caller wasn't
hearing
him or they were getting pummeled so badly from calls not even close to
the
original, that he moved on. Rate is king when time is
limited.(dxpeditions
only have so many days)

William,
Thanks for idea. Are you absolutely right - 5uH is too small for 160m.
Looks like I have a wrong toroid. After playing with amidon toroid
calculator, I found that 20 turns on T300 will give around 5uH (like
mine),
T300A-2 will give 45.6uH

5.7 uH sounds too low for 160M, I?d want ten times that to keep the
winding impedance >>50 ohms.
