  Same problem with people using web SDR radios . No way to compete with home 
made receive antennas. You dont needto invest time and money anymore . All you 
need is a magnetic loop in your 3000 square feet backyard and claim it works 
fantastic .

 This growing practice of hiring a remote in another call area far from
your own QTH, then working wild and exotic DX wile preventing deserving
locals operating from their home stations from working same DX, is
abominable and just plain unethical. I lost what respect I had for a
couple people I heard work 9M2AX this morning when I heard them do that.
I heard another guy do that last week that I've only just barely heard
on 160 in the past across the country; he was at least two hours beyond
his own sunrise, so obviously hiring a remote, probably that big one up
near Carson City, Nevada, same station these two guys this morning were
probably using. The week before last, there was another east coaster, at
least 2-1/2 hours past his sunrise, who did the same thing at, most
likely, the same station. I bet the owner of the station is advertising
it as "WORK 9M2AX on 160 from here!!! Only $XXX for a half hour!!".

I hope these guys are putting an asterisk on their 9M2 QSL cards to
indicate they didn't work Ross from home; but I won't hold my breath
that they do.

Re: Topband: 1 center point to ground all 8 beverages??

2016-03-22 Thread luc kerkhofs via Topband 
Very interesting, reading as always,

This brings me to another question, how do I need to handle grounds in a switch 
box with 3 antennas ?

 I've done this for 31 years from 3 different locations with
 no problems.

          I agree.  I've
 done this since installing my first set of 7
 Beverages in 1985 arranged like wheel spokes and have never
 noticed
 crosstalk problems.  I even sometimes switched two in
 parallel to
 listen in two directions simultaneously in contests (NE and
 W when I was
 in Colorado).  Now I prefer diversity (Beverages on one
 RX and an RX 4SQ
 on the other RX) for contests.

 Sorry Lou, but I disagree with that
 comparison , considering the path between EP6T and NA, you
 should 
 compare the number of QSOs between K1N and  JA

   Jeez how difficult can it be from the US, anybody
 with
   100W and a wet noodle for an antenna can work it. On
   80 I´m sure at least from the east coast they can be
   worked all day long.
  
   I don´t know about 160 since so far they haven´t
  been
   stronger then S2 due to geo mag storm and poor
  propagation
   66 degs north where I´m at but so far I´m very
  disappointed
   in their 80m operation, they never listen for EU or
 any
  other
   area, they work 99,5% NA, it is the USA/Canadian QSO
  party.
   I would have expected a totally different action by
  that
   bunch of operators, I´m very very sad and sorry to
  see
   where it all has went to.
  
   Now this might not be the case on 160, if I´m lucky
  propagation
   might get better and I might get a shot at it.

   Why not call around 0700Z after the
   band closes to EU and before it opens
   to JA?  A bunch of us in CA got them
   in the log last night fairly easily.

Re: Topband: Feedpoint of short RX vertical

2014-06-08 Thread luc kerkhofs via Topband 
Jim,

I made a braid breaker by using a binocular core 73-202 with 2 turns  primairy 
and 2 turns on
secondary . The term braid breaker comes from John s latest edition of low band 
DX ing

I found that it is difficult to get signal levels identical on both elements 
when using it, so maybe better to use a good common mode choke at the feedpoint 
.

It DOES make sense to decouple the feedline. I've never heard of a 
braid breaker. Under NO conditions should you open the shield == that 
prevents the shield from being a shield. The good ways to decouple the 
feedline are 1) a good transformer, a good common mode choke, and 
radials. See Chapter 8 of http://k9yc.com/RFI-Ham.pdf for winding 
guidelines for the choke.

Topband: Feedpoint of short RX vertical

2014-06-07 Thread luc kerkhofs via Topband 
Hello,
 
trying to improve my RX setup, I have a question .
 
When feeding short RX verticals with a coil and resistor in series, does it 
make sense to decouple the feedline
at the feedpoint with a braid breaker ?

Tom,
 
one of 2 elements is very close to the house ( 20 ft ) and coax is lying ON the 
ground, so I guess it is best to use a braid breaker ?
 
In fact it is a test setup . I also have a receiver 500 meters inline with the 
antenna direction so I can 
check the F/B of my test setup

Hello Frank,
 
no it is 11 m high vertical without toploading feedpoint is matched with

Hi Frank, 

My 8-circle array uses low impedance verticals, not high impedance 
verticals like the Hi-Z. My verticals use an inductor and resistor at the 
base of each vertical. In a Hi-Z array each vertical connects directly to 
the input of a high input impedance amplifier. 

The purpose of the radials in an array of short low impedance verticals 
is to provide a reasonably stable feed point impedance. Eight 23 meter 
radials provide adequately stable feed point impedance at my QTH. 

Radials are not needed at all in a Hi-Z array.

hi luc 
so you use a hi z rx arrya and you have matched the 7m long radials with a coil 
in resonaze?
