Subject: Cushcraft R7 Installation
Date: Wed, 29 Jul 92 13:41:40 EDT
Organization: Princeton High School, Princeton, New Jersey

Just finished installing the new Cushcraft R7 antenna (40-10 including 
WARC bands) on a 20 foot aluminum mast at N2GJ.  The assembly was a 
breeze (though we were short a couple of stainless steel screws - one of 
us has a fabulous junque box, though) taking about an hour.  The 
directions are very clear, with lots of pictures.  The mast is attached 
to the side of the house with a Radio Shack 12" antenna mount kit 
(~$12.00) and we used RG-8X feedline.  The MFJ SWR Analyzer shows nominal 
SWR on all intended bands plus ~2:1 on 75!  
     
The first station worked was UZ1AWX, Art, in St. Petersburg, in the 
former Soviet Union, on 14.010, CW with the Kenwood TS-440/AT at 100 
watts.  RST was 579.  Several other on-the-air tests confirm good matches 
on all bands.  A brief test on 75 yielded "acceptable SWR" reading but 
poor performance compared to the G5RV at 45' which is expected.  After 
all, the antenna is not REALLY designed to work there!
     
If anyone is interested, I will post other reports on this antenna, as I 
gain more experience with it.  The best part?  My wife, Connie, N2ATJ, 
helped with the installation and says "It's cute!"  73,

Hmmm, I bet there are no fewer than 100,000 print shops in the USA that can
do the same job!  Probably even one or two in your own neighborhood.  Why not
Try your local print shop, you might be surprised at what they can do.  At the

The PRO-43 is a "new" entry in the market.  In fact, replacing the top of
the line RS handheld.  It should at least be up to the standards set by
the ICOM R1, AOR1000 and others.  If fact, it should surpass them leveraging
the latest technology and innovations suggested by other scanner designers.

Certainly we can expect a "handheld 2006".  Anything less is retrograde and
warmed over leftovers.  The PRO-43 is kinda like SPAM.

Here is some Yaesu FT 470 technical tidbits
  
VHF First IF 21.7 mhz
From 106 to 156.975 mhz the first mixer uses high side injection
the local oscillator frequency will range from 127.7 to 178.575 mhz.
 
From 157 to 201 mhz, the first mixer uses low side injection
the local oscillator frequency will range from 135.3 to 179.3 mhz.
 
UHF First IF 47.75 mhz
From 400 to 500 mhz the fist mixer uses low side injection.
the local oscillator frequency will range from 352.25 to 452.25 mhz.

the UHF local oscillator also has a strong first harmonic. if you 
near a strong 704.5 to 904.5 mhz signal, you should be able to 
tune it in. I have done so, without any problem, except poor sensitivity.

I am having trouble getting info from Toyota about installing 
146 Mhz and 440 Mhz rigs in a 92 Camry.  All they say is "don't
do it".  The owners manual states at the front of the book to not
install two-way radios and it repeats the statement in the section
on air bags.  Certainly, I don't want to key the rig and have the
air bag deploy...:-)

So, I'd like to hear from anyone who has a rig in a 92 Toyota Camry.
What would be helpful is type of rig, where mounted, power used,
location of antenna, routing of coax, and type of antenna.

Certainly, with proper installation it can be done in a way that
doesn't interfere with auto computers, air bags, etc.

Thanks.

I favor motorola.  Does your friend know what he's getting into?
Finding a used repeater is easy.  Setting it up for the right
frequency may not be.  And he'd better remember to get an
appropriate duplexer too; it may cost as much as the repeater.

Surveying work rarely needs results in real time.  Usually survey crews
record the exact timing data that they receive at the site, and then
go back to the office.  When the DoD releases the exact ephermis data,
they then use a PC to reconcile their timing data with satellite postition
and get high accuracy information.

Personally, I think SA (selective availablity) is a silly idea, but then
I think most of the DoDs ideas about 'security' are silly.

My experience with an Avanti glass mount was quite good.  You MUST remember
to ground the coax to the car at the coupler box.  The Avanti comes (came?)
with a clip and a short piece of braid.  I was able to find a screw near
the mount point that made a good connection to the body.  In this
configuration the antenna works better than a quarter wave and similar to a
5/8 wave.  Not as good as the 1/2 wave J that I had on the bumper for a
while.

Another friend installed one of these and didn't ground it and found that
performance was very bad.

The downside with these antennas is that it will pop off very easily if you
hit an obstruction like a low garage door.  I stopped using it when I started
keeping the car in the garage.

I recently installed one at one of the Worldnet sites.  I am a little
skeptical of the durability but I guess the price is low compared to a
real (commercial) repeater antenna.

As the one on top of the 200' tower I must say it's extreme light
weight made installation relatively easy.  I was able to hold the
antenna in one hand and fiddle the clamps with the other.

We put it at the top of the tower so the top of the antenna is free to
swing.  Initial performance was good.

The proof will be to see how well it survives the winter.
