RE: [Repeater-Builder] newbie looking for info

[Eric Lemmon]

Mark,

Oh, man, are you in for an avalanche of advice!  Rather than duplicate other
posts, I would like you to consider a few questions:

1.  Why do you want to build a repeater?  Is there no repeater serving your
area now and you perceive that one is needed, or is an existing repeater
constantly being tied up with inane discussions by long-winded yakkers, or
are you interested in delving into a new area of technology to better
yourself?
2.  Do you have the money to build a first-class repeater, or are you
limited in budget and want to "get by" with a minimal system as cheaply as
possible?
3.  Have you applied for and received a repeater pair from the cognizant
coordinating body?
4.  Are you planning to do this by yourself, or are there others with
similar desires who will chip in labor and/or money?
5.  Do you have a site in mind, having considered the ongoing costs for
rent, power, insurance, etc?

The above questions are not intended to discourage you, but #2 is the real
"snake in the grass."  In the many years that I have been monitoring the
posts on this list, I have lost count of the number of posts from "Newbies"
who start out with the notion that they could set up a 2m repeater using a
couple of Amateur transceivers, a flat-pack notch duplexer, and a home-made
J-pole antenna.  As you learn more about the realities of a 600 kHz split,
you will quickly realize that this optimism is based on a lack of technical
knowledge.

But, let us not be too pessimistic here.  There are Elmers on this list who
will cheerfully answer your questions and guide you through the jungle of
misinformation and misunderstanding.  Do not be afraid to ask basic
questions for fear of flaming- there are those on the list who become
impatient with basic questions, to be sure, but there are many more who
relish the opportunity to "take the hand" of someone who sincerely wishes to
create a device to serve the community and advance the knowledge of the
radio art.

If your resources are truly limited, perhaps a UHF repeater in the 440 band
would be an inexpensive project.  The 70cm band uses a 5 MHz split, which
can be handled by a relatively inexpensive "flat pack" notch duplexer that
can be purchased new for less than $ 350.  This is in stark contrast to a 2m
repeater which has a very narrow 600 kHz split and requires a more elaborate
duplexer that costs at least $ 1,500.

I encourage you to pursue your quest for information.  You have come to the
right place.  Welcome!

73, Eric Lemmon WB6FLY

You have a Mastr Executive II mobile radio that has 41-80 watts of power,

RE: [Repeater-Builder] Side mount to wooden utility pole?

[Eric Lemmon]

AJ,

I have five antennas now in service that are mounted to wooden utility poles
using Decibel Products (now Andrew Telecom) DB365W mounts.  These come
packed as a pair of brackets for about $75, and are available from
commercial radio supply houses like Tessco, Talley, and Hutton.  These
brackets are immensely strong, and can also be used to mount a mast against
a masonry wall.

Generally, you don't need to concern yourself about offsetting from the side
of a wooden pole, since it is nonconductive.  That said, most installers
will install the mounts close to the top of the pole, simply to achieve the
greatest height possible.  When the DB365W mounts are properly installed,
the mast actually is offset about 4" from the side of the pole.  I normally
use one or two heavy galvanized washers on the upper mount, to compensate
for the pole taper, thereby ensuring that the mast is plumb.

Looking at side mounting a fiberglass repeater antenna on a wooden utility
pole. Previously had railroad microwave dishes at the very top (about 55'
AGL) which has since been decommissioned. Our permit allows up to 35' AGL to
the base of the antenna. We've been going back and forth with one of the
local hams that happens to be an engineer with regard to building a side
mount from Unistrut channel with roughly a 36" offset from the face of the
pole. 

My question would be what exactly is the minimum spacing for side mounting
off of a wooden utility pole? Coverage does not necessarily need to be
omnidirectional as there is a fairly large ridge to the east of the site and
the targeted coverage area is to the north and west.

The photo that got me thinking about this was from the 147.03 repeater move
site documentation - 

http://www.qsl.net/ac7el/RepeaterMove/Antennas.jpg
 

It appears this antenna is maybe 4" offset from the side of the pole.

I'd love to be able to equip every site with an over-kill 
Deep Cycle Battery Bank/Pack. I'd just hate to have to pay 
for installing deep cycle batteries at every site.

The proof is right in front of most people... Walmart is the 
worlds largest retailer because their products appear to be 
the most cost effective (IE Cheapest...).

The 80% value is not in stone, totally adjustable by a pot in 
the LVD as well as the re-connect value. 

Nominal float voltage would probably be about 13.8 vdc, equalize 
values higher and the discharged state is about 10.8 volts in 
many examples posted for various battery types. That informally 
works out to just shy of 78% discharged before the LVD removes 
Vdc from the Equipment. 

If the battery "craps out" (just for you Allan) in a few years 
I can and would simply replace it.  Three or four years back the 
8D Napa Brand Batteries cost me about $129 each.  The latest 
purchase a month back (for a new location) was a Sam's Club 8D 
for about $159 each.  

Although there are different caution issues with paralleling 
batteries, I can and have also been doing said at a much larger 
off grid site.

A big difference with using the 8D battery versus a very nice 
pack of Deep Cycle packages is that I'm not spending someone 
else's money to achieve the same goal.

I have 2 GM300 radios, both are model M34GMC09C3.  As far as I can tell 
they are 25 watt UHF narrow band radios.  Is there a lookup table

I'd recommend joining a club that has a repeater and let them know you
are interested in learning how their repeater works.  You'll learn a
lot easier from an elmer in person than reading the materials on
RB-Tip (even though it is an excellent source for more advanced
topics).

Sure, it disconnects the charging source.

But the load is connected across the battery.

There is no provision to disconnect the load from the battery.
Without this, you can still over-discharge and damage the cells.

As a rule, I am far more concerned with battery health, than
disconnecting the bleeder resistor in the power supply from the battery.

I assume it disconnects the charging source at night. In my application 
I am going to replace the "PV" with "power supply"


Quote "When the PV voltage is greater than the battery voltage, IC4 
turns on and sends power to voltage regulator IC3"

What do you think?

I agree with the other poster - it has no low-voltage disconnect.

The SCC3 is just a charge controller; not an LVD.  There is no
load provision on that board.

Me too Chuck, I want the low voltage disconnect to protect the batteries 
and the various solar controllers mentioned have that feature and more.

 Look at this kit : http://www.cirkits.com/scc3/scc3specs.html

Around $40.00 looks like it will fit my requirements. I plan on feeding 
it with a power supply instead of solar panels. Right now I have a 
Samlex 20 amp switcher hooked directly to the batteries set to 13.2 
volts (works great). I would very much like to protect the batteries 
from over discharge.

If it were me... I would make  2  C2037 mulitcouple filters. You have the cans 
to do it .. 
Just takes a few cables and tune it up.. The C2037 ( Sinclair ) will have a 3

Re: [Repeater-Builder] Scom 7330 Ideas

[James Adkins]

Good morning Steve,

You have indeed made a good choice!  We installed our 7330 about a month ago
and it hasn't missed a beat yet.
Make sure you take advantage of the custom audio library function.  We have
recorded messages with information about the repeater that are played back
when a user enters a certain DTMF code.

The controller also alerts us when the on-board lithium battery gets below
2.3v so we know a trip to the hill is needed.

Another alarm we've set up ties a logic input to our on-site UPS that is
used for our Motorola Canopy wireless Internet radio, Linksys router, IRLP
computer and DekTOP windows based PC that we use to remote control and
program the SCOM7330.
When we get the alarm that indicates the batteries need to be changed, the
controller alerts us of the problem.

We are also taking advantage of the if-then-else feature to use two logic
outputs to control fans that keep our repeater running cool. Several other
controllers have a fan control output, but none that are as customizable as
the SCOM's.

You can also use the on board CTCSS tone encoder to generate your PL tone,
or simply use logic from the controller to control an external tone encoder
board.

We currently have a UHF repeater on port #1, a 220 repeater on port #2, and
IRLP on port #3.  The controller links and unlinks the repeaters for us for
our weekly net, too.  Since all the club's repeaters link to the UHF by
radio, the controller also turns off all dropout delays, we strip the PL
from ID's during the net, and it removes the courtesy tone so the UHF
machine is transparent in the linking process.

You'll also enjoy the use of balanced audio on RX, TX and CTCSS encode
lines.  Before we had the SCOM, I always thought the CAT controllers had the
best sounding audio.  Now, they're a close second.

If you want a copy of my text file that we uploaded to the controller, send
me an e-mail direct.

Enjoy!

[Repeater-Builder] Scom 7330 Ideas

[KD8BIW]

Hello all,

 We will be upgrading our controller to a Scom 7330 soon, and i'm looking 
for any unique and interesting ideas for programming, options, etc.  Did you do 
something odd, different, or just plain cool with your controller, i'd like to 
know.  These are capable of so much, i'm looking for ideas.  So far, I'm using 
2 ports, 1 for the repeater and a 2nd for a control receiver.  I think I would 
like to link to a local 440 repeater, but not sure.  I'm open to ideas and 
suggestions.  

Thanks!

Steve KD8BIW
