Hi Guys...

I will try phoning you later-(I'm in the middle of  TV tower work before 
rain..)  but hope you got my message... I guess there were some plan changes 
or did I misunderstand Tuesday ? ...original plan was Dad goes to Lewiston 
Wed (solo) and I come down Thursday morning for a few hours .I had planned 
to get back for early afternoon..


I didn't get ur phone message until after I had left home at 8:45.  I had to 
stop in Newmarket when I realized I had left some crap in my car trunk and 
had to unload it into Jens car  at her work, so I'd have room to bring more 
up form your garage today ... then, I realized you may have left a massage 
on my magic jack...Unfortunately, MJ  it is not like Bell call answer with a 
notification beep or light... so I never think to check for unexpected 
messages.. I too use to Jenny's Bell notification and  her call 
displaysorry. I  was coming from Jennys and quickly sotpped at my place 
to call you to see what else you neededbut  you had already left..


I left a message with John White asking if he or Matt could lend a tonight 
when you get back ...but haven't heard back...if he or John can't drop by, 
let me know ASAP...maybe I will just drive down after diner time tonight and 
do it, then come back   


I was on a stand-by for a new dentist for this aft...but no luck...(soonest 
sked is next week- when I won't be here...so going to try again 
tomorrow..maybe different Dr...


Since you left Lewiston for today, I assume the Insurance adjuster re-sked? 
I wanted to get extra stuff out of garage so he didn't think it was part of 
the claim  but  you were going to go through it first ...you may want to 
keep some of the stuff yourself after a Bleach wash and  wire brushing wheel 
on the grinder to clean up handtools... I can get Matt to through Fridge in 
car to leave at Johns until I can get down.. but really not much there that 
you cant say is waiting to go out with you got crap or just cover ...


I drove back home after I got your mesage needing coax. I had F56 but only 
short lengths of Coax.. .I did have a working  cut-out tool, but no 
bit..( probably some in the boxes in your garage_If Matt comes over, 
.Matt should have a cut-out  from  work...if not, he can  use a utility 
knife  -or drywall saw if not going right into full drywall?..


Have to run and will call you later to see if John W or Matt  phoned 
you...( no calls received here)


And if it's urgent to get the  TV done (and items out of garage), I will 
drive down tonight after rush-hour and just get back later  tonight... just 
want to make sure you aren't too tired after Lewiston..

An interesting thread on an interesting ham!  I recall seeing a picture in
one of the magazines of Don at age 80+ at the top of one of his rhombic
poles (some 100 ft each I believe) doing routine maintenance.

I was browsing through older QSTs recently and ran across an article by 
him

in November, 1937 titled Making the Most of Directive Antennas-Practical
Pointers on Operating a Number of Antennas in Limited Space.  This was, 
of
course, before he purchased the Press Wireless property in the hills and 
it
describes his Sterba Curtain and phased element wire beams.  Apparently, 
he
placed so much faith in his antenna static discharge system that he did 
not

shut down during thunder storms!

Re: Topband: DSL vs Wi-Max

2013-08-01 Thread Milt -- N5IA
We feed our wireless ISP system with 6 each, Gig E fiber connections at 
dispersed locations from three 3 different nationwide carriers.  There is no 
need for a bottleneck.  Diversity of feed is the name of the game.  In town 
or beyond DSL and cable, there is a choice.

Dave, I also have Wi-Max to run most of the computers but I have found

is 1.5 meg up and down every time and all the time and with Remote Rig
allows perfect 35 WPM keying from the remote op on the mainland (in NYC)


I tried two different wireless ISP's before DSL came to my area.  I
found out that the wireless ISP's only had a single T1 line to the
internet, so it didn't matter what speed the wireless link was,
there would be bottleneck at the head end.  The DSL also has this issue
to a certain extent, but it has worked much better for remote station
control.

Topband: Signal attenuation from foliage near 160m antenna

2013-08-01 Thread Mike Waters
This subject has been discussed here plenty of times in the past, and the
consensus has always been that trees and other foliage near a 160m antenna
has a negligible effect on the transmitted signal. That's what I have
believed for some time.

This was discussed last month at
http://www.eham.net/ehamforum/smf/index.php?topic=90638.0 . This article by
Carl Luetzelschwab K9LA appeared in the  March/April 2006 NCJ titled  Low
Band Antennas and Trees. LINK:
http://k9la.us/Low_Band_Antennas_and_Trees.pdf .
Look at the chart and discussion there. It flies in the face of previous
observations by a lot of intelligent Topbanders.

I'm not at all saying that I agree with this. But it certainly does seem
that after the leaves came out and the weeds grew around my 160m
inverted-L, my signal on the Reverse Beacon Network is nowhere near what is
was in the early spring. I doubt that it has anything to do with the tall
weeds under my elevated radials or the oak leaves near the inverted-L.

But never mind all that; what do you gentlemen think about this article? I
don't know what to think.

 Without doubt foliage has measurable effects on the antenna when it is 
close to a voltage

point (speaking from experience with loops), so Carl's findings make good
sense.

Topband: Signal attenuation from foliage near 160m antenna

2013-08-01 Thread Bob Kupps
Interesting study which suggests not placing a 160m vertical closer than 12' to 
a tree, if feasible. There are certainly lots of vertical radiators working 
well amongst towers. We won FD 4 years in a row using 5 watts to a random 
vertical wire hoisted up the aluminum mast of a sailboat amongst all sorts of 
other vertical rigging wires, but like 99.99% of all hams, have no way to 
conduct a meaningful comparison.

Detuning of low band mobile antennas, can take place when close to 
trees/foliage.  Voltage point corona discharge may be visually noticeable 
when running

higher power.
