Does anyone have a schematic for an Astron RS-12A?
A person emailed me directly and ask for a copy which I could not
help with.

If you do, can you scan it and email it to me.
Required size is approximately 900 high by 600 wide so it will
print out on a common sheet of paper when printed.
Image file size should be no greater than 100k
(see )

If you have a copy of the schematic and have a scanner, I will
give you pointers on how to scan the image and make a nice
printable copy that doesn't require a lot of size.

Thanks,

Kevin

I was asked to post this again, so here goes....

Hello All,

I recently received several requests from people on the list
wanting to obtain the large heat shrink I use to seal the Comet
and Diamond fiberglass antenna joints with. This stuff is great
for sealing connectors, antenna joints, covering shovel and
sledge hammer handles and covering tool handles like large
Crescent wrenches.

This shrink has an inert sealant that melts as the heat is applied
for shrinking. This creates a good (won't leak if it was drug
across the Atlantic) seal. Well maybe not that good......but damn
good.

It is available from Jerry Conn Associates Inc.
They are located in Chambersburg Penna.

The manufacturer is CANUSA. Pronounced canoosa.

The available sizes (unshrunk of course) are indicated by the
model number.
Example: Part number;
CFTV-400 is .4" (that's point 4 inches)
CFTV-1100 is 1.1" diameter
CFTV-1300 is 1.3" diameter
CFTV-2050 is 2.05" diameter and so on

These come in a 4 foot length.

I believe the shrink percentage is 50% of original, This is not
fact however.
I don't remember the spec. on shrinkage off hand... but it does
shrink a lot.

These are the available sizes:
The ones with pricing are normally in stock.

CFTV-400
CFTV-750
CFTV-1100
CFTV-1300 $5.16
CFTV-1700 $5.95
CFTV-2050 $11.41
CFTV-2750

These people have a $50.00 minimum order, so get together with a
friend or two and place an order.
They will sell directly to the public.
The models listed without pricing are available through JCA, but
are usually not stocked.

If interested in purchasing, contact Tracy at Jerry Conn
Associates.
1-(800) 233-7600 in PA
1-(800) 233-7370 out of PA
1-(717) 264-1547 Direct Line from anywhere.

The CFTV-750 is great for RG-8/PL-259's or Type N connectors.

In our business, we use a propane torch to shrink the tubing. It's
wall thickness is very good, and not easily damaged by a
little excess heat. You can actually catch it on fire and not
damage it badly. It doesn't shrink well in windy conditions,
(requires lots of propane) In severe wind I use MAPP gas as it
gets burns hotter than propane, although this is usually not
necessary. I have used this stuff for years and can attest to its
quality if installed properly. There are other cheaper brands of
this stuff than CANUSA , but (in two words) they suck. There is no
equivalent. I tried them all.

Here is a pix of the stuff we use in the catv industry.

They also have a good quality Self Amalgamating Tape that is much
better for covering connections than Black Tape.

Hi Joe,would sure appreciate the help if you could recall how to do the
programming.

I'm using a PSX-SE on UHF, so I must have programmed it for the ham
band, but I don't recall how. I probably had to edit the hex data. If
you can't find anyone else who can do it, I'll research it more. It can
be done. :) *** One word of warning: The oscillator becomes
intermittent at low temperatures (<20-30). I don't recall how I got
around that problem either, but I think it involved adding or removing a
transistor. But when it works, it works very well.

If you find out on the phoenix-S, let me know too. I've got a

couple of

BTW Kevin, thanks for the heat shrink source. We will definitely get

some!

Tnx,

If you are on 2 meters or lower, you can point three in the same
direction and the fourth in another, but the elements cannot be at the
same level (elevation). You will, however, loose gain in the direction
of the three elements by facing one in another and could have a problem
if you are on a large tower. The elements must remain at the required
vertical spacing. At 440 and up, you cannot - they must all point toward
the same direction. You might get away with it at 220.

Anybody happen to have any spare channel elements for Mocom 70's? If so,
please contact me privately with your asking price. Thanks.

I am looking for some help with antenna questions for my GE MASTRII/RANGR
Repeater
What is the consensus on 4 bay dipole arrays for repeater antennas ? I
have looked into the coverage maps with both the 4 bay dipole array and an
Omni stick. The closest repeater on the same pair is 50 miles away. The
idea of going to the array was to place a null in the direction of the
other system. According to my coverage maps it cleans up and expands my
coverage going to the Omni.
Now for the second part of the question. The 4 bay array antenna have a
phased harness can I put three of them at the same level and the fourth
antenna as a reinforcement in the direction I want ??

Currently the 4 antennas on the array are on the western leg pointing North
and South my coverage is for no better word Terrible
7 miles away to the east I get an S4 , to the west 20 miles an S9

oh well i got all the pins out for the back of the radio and they have great
rx in ther i use one for tx and one for Rx for a repeater they work
great.....i can give u that and i am working on putting them into one rack
mount at thins time use them for links also good rigs looking for more
for uhf and vhf

kevin do you have any information on putting together a remote base.
I just never did that and i'am think about doing it. I think it would be fun
to do. thank you bill brown-----k5py.

What controller do you have?
What radio do you have available for the remote?
What band(s) do you want to link to?

Kevin

Brent,

Well, I was going to try and crystal mine up for an uhf link radio. Pin outs
would really help! So would any tune up instructions you might have.

Thanks!

TD

kevin i was thinking about building a remote base out of a 261a kenwood.
would you happen to have any info on doing that I've built repeaters but
never a remote base,thank you. bill--k5py

Bill,

Tracy, K0DOE, here. I built a dual band remote using a Kenwood TW-4000A. Works
great! I used the controller momentary outputs to 'strobe' (ground) the mic
up/down switch for frequency change. The voice module installed in the radio
outputs the frequency readback. Additional outputs from the controller could
be used to adjust power, change to vfo, etc. Guess it depends on your
controller what you will be able to do... Definitely helps to have frequency
readback! I know of several remotes that have been built without it and they
are always where their not supposed to be!
