Hi Lars,

In a message dated 96-09-19 11:37:44 EDT, you write:

> Even if you have impedance-transformation you will still have
>THE SAME
>radiationresistans so that the groundloss/rad.res. ratio will remain
>unchanged!

I'm happy to see someone de-bunk this misconception. 

It appears in too many articles and handbooks here in the USA. There was even
an antenna that claimed a folded element increased radiation resistance and
reduced the need for radials, they gave Los Alamos National Lab as a
reference.

Los Alamos "suggested" they remove the reference, and they did.

Thank you for de-bunking this dark magic.

Here is an interesting statistic.  When K2MM, WN4KKN and WB5VZL 
visited about a month ago, John and George stayed up late 
one night coming up with the available four letter callsigns
with the number as the second character (K#, N# and W#).

Here is the breakdown by call area:


0     987  
1    1129   
2     766   
3    1032   
4     578    
5     830  
6     546  
7    1009  
8    1126   
9    1081    

The total is 9084.  Guess the Fours and Sixes get the fewest 
choices.  I think the FCC made a few more calls "available" after
this was done, but I don't have any data on the 2 year waiting
status.

I was amused to note that the CQ Mag contest calendar this month has the
wrong dates for CQWW - not in the short run-down at the front of K1AR's
column but at the back.  Tuesday and Wednesday, indeed.  My XYL might like
it better, but I doubt my boss would agree.

Message-ID: <199609192112.RAA23273 at answerman.mindspring.com>

Several months ago there was a discussion on balloons/antennas.  Someone was
building
an archive of articles and I thought it was on the KA9FOX page, but there is
only one article
there.  Anyone know where the archive is?

An excellant way to remove a ground loop without destroying the RF shielding 
properties of a shielded cable is to connect one end of the shield to ground 
through a capacitor.  Something like a 0.1 or 0.01 uF will keep the shield 
impedance low for RF, yet appear as an open circuit to 60 Hz.

One other thought on DVP hum.  I have an old Nel-Tech DVK 100 and the
so-called hum is actually the receiver picking up the micro processor.  Gary
at Nel-Tech spend quite a bit of time on this.   Someone borrowed my DVK
about 8 or 9 years ago for running the SS
from N4RJ (forget if it was Bill KM9P or Trey WN4KKN) and said they heard
the hum on the
Kenwood TS930 or 940.   I sent it back and Gary worked on it, but said
except for processor hum
he found no Rf feedback or hum.   I tried it with a TS940 and it sounded OK.
The real key I think is making up good connector leads!

In my case the Yaesu picks up the so-called hum where my ICOM does not.  I
have the MFJ I use with my Yaesu now and I hear no hum from it al all.

BTW:  I have an ACER 385/20 notebook that puts processor hum on 10 and 24
Mhz when its laying on the operating table.   Sounds just like the DVK.
