[Repeater-Builder] Remote monitoring of repeater site

2005-05-31 Thread banjupb
Hello learned group members.
Does anyone know anybody that has a remote site monitoring system, ie 
battery state, vswr, entry, generator start, fuel level etc.
I have a site in Africa that has 3 remotes site that we need to 
monitor localing and if possible on a dial up modem from here in 
Australia.it will need to leap frog thru a parallel telemetry rf link. 
I can be contacted direct or thru the group. There was a system that I 
saw many years ago but the memory is not that good to go back to a 
flyer some 15/20 years ago. I need a solution asap. Cheers.

Why not adapt something like the GME Telemetry system?
http://www.gme.net.au/commercial/telemetry.php

It's cheap and could be controlled through a host PC running PC Anywhere.
You could interface SWR and other analogue interfaces to the analogue ports
and then config the software.

Just my 12.5c (Inc GST :-)

Re: [Repeater-Builder] LTR controller on a GE mastr II Help please

2005-05-31 Thread Steve S. Bosshard
Back in the old days I converted several MII's in 800 Mhz from GMARC to LTR.
There was a mod the the channel element where an un-used pin applied txdata
to the compensation circuit in the element - This was a mod from Cook's in
California where they made a sharing system to run both GMARC and LTR on the
same repeater.

You should have no trouble applying data to the channel element - you may
have to invert the data and seemed like a 10kohm resistor was used - I use a
test ID code on IDA RLC's so that when I ground the test pin it will send
the test ID and a subscriber unit should unmute on proper decode.  Once I
have the transmit working, then I connect to discriminator audio and get the
decode working - standard test is to use 100 hz audio at 1kc deviation to
simulate mobile data for level setting, and txdata set to 1kc peak to peak.
I usually set voice for 2kc in for 2kc out at 1000 hz and total system
deviation at 4.0 kc.

Wish you success,

Steve

RE: [Repeater-Builder] Remote monitoring of repeater site

2005-05-31 Thread Jeff DePolo

Just about any decent broadcast-oriented remote control system will do what
you want.  For examples:

www.sinesystems.com - model RFC1/B (bare bones system)

www.burk.com - ARC-16, GSC3000, VRC2500

www.broadcasttools.com - several different units; look at their upcoming
VMC-8 product

The ProTek series from PageTek (www.pagetek.net) is pretty popular for
non-broadcast telecom sites.  Their basic Jr. model may be all you need.

Keep in mind that you have to provide the sensory inputs to most of these
remote control/telemetry units.  Most manufacturers sell temperature
sensors/probes, AC voltage sensors (which you can mimic just as easily with
an unregulated DC wall wart and some additional protection), etc., but for
something like fuel level, you'd need a sending unit in your diesel tank or
a pressure transducer for LP to provide a varying DC voltage to feed to the
unit.

Most will work with 4-wire links (or RF equivalent) that will pass FSK modem
tones (Bell 103), or you can go with outboard modems for higher data rates,
or IP connectivity if it's available for some of the higher-end models.
Most also support some form of dial-up remote control (DTMF control, with a
voice synthesizer for telemetry readback).  Not all of them are capable of
multi-drop (parallel) communications however.  See the manuals on the
respective web sites for details.

[Repeater-Builder] Duplexer Cable Probe/Loop Lengths

2005-05-31 Thread skipp025
 I have not experimented with the effects of jumper length, 
 since I usually ordera duplexer made for a specific repeater 
 pair, and merely verify its operation

 What does the length of the cables between cavities affect 
 in the duplexer system? I seem to vaguely recall it had 
 an effect on the bandpass to band reject slope and the 
 position of the notch (separation?) , but I'm not
 completely sure of this.

It does... 

In some self contained duplex combiners (Cellwave as an 
example), one will see two lengths of cable stubs from the 
cavity probe/loop up to the duplexer harness T. 

One length places the reject slope higher on the tx side 
while the other length places the slope higher on the rx 
side. 

The proper probe/loop to harness stub length can greatly 
increase a desired notch. Decibel's VHF Cavity stub length 
adds over 10dB to one suck-out cavity. 

So you'll find three stub lengths in use... depending on 
where you want the enhanced cavity/cable operation. 

cheers, 
skipp

Right-so far the only ham rig I've seen that can do split tones is the
last of the Azden radios. I have a 6M version, and it can do it, since
it programs like a commercial rig, just from the front panel. In fact,
in other countries where type-acceptance isn't an issue, I'm pretty sure
they sold the exact same radio into commercial service.

Most Alinco radios can do split-tone: DR-605, DR-620, DR-435T, DJ-G5T.

Re: [Repeater-Builder] Tait 2015?

2005-05-31 Thread nate
 Anyone know if these radios can be used even in simplex mode? (on 220)
 Thanks,
 Robert
 (of course within the ham band ;-)

If you're talking about the LTR trunking variety on 220 MHz, they will TX
and RX in the ham bands after much twiddling with the programming
software.

However... they're narrowbanded (low deviation) and the receiver I tested
was very very deaf in the ham band.  They would NOT receive and transmit
on a standard split or set up talkaround (simplex) correctly.

Would have worked to have one for TX and one for RX as a repeater, but you
couldn't use them as mobiles, etc.  And with the narrowband deviation
they'd have sounded bad.

They get horrendously hot on TX, didn't seem to matter if the power was
set higher or lower.  They're just a hot-running radio with a very small
heat-sink.  The UHF non-LTR trunking variety also does this.

Perhaps the receive sensitivty could have been remedied, if I could find
any tuning information about them, but I screwed up the receiver I was
playing with on the workbench while I was digging for a COS circuit and
dropped a tool.

I never went back to messing with them.  That receiver unit was dead as a
doornail after that incident (zaaap... oops, let the smoke out!) and I
only had two.  Both the dead and the live one are sitting here in storage
if anyone wants to mess with them.

Oh yeah, the BNC connector for RF is also a pain, but they do usually have
a punch-out for a DB-9 accessory port which would make a good place to
bring out COS/PTT, etc.

 Right-so far the only ham rig I've seen that can do split tones is the
 last of the Azden radios. I have a 6M version, and it can do it, since
 it programs like a commercial rig, just from the front panel. In fact,
 in other countries where type-acceptance isn't an issue, I'm pretty sure
 they sold the exact same radio into commercial service.
 
 Most Alinco radios can do split-tone: DR-605, DR-620, DR-435T, DJ-G5T.

   Will the FCC certification of the transmitter need to be changed
  because of the additional circuitry?

Re: [Repeater-Builder] Time-Out-Timer Length

2005-05-31 Thread Bruce Nanney
Eric and who ever is interested,

The T.O.T. I have done some reverse engineering on it.
There is 120mfd cap. in the bottom of the can. If you increase it to 340mfd, 
it will lengthen to about 7 minutes.
I think this will be enough for what I'm trying to do. I could increase it 
more , but there is not enough room for a larger cap. Thanks Bruce KD4BOH.

 Bruce,

 What model radio is the TLN1361A used in?  I did not find that number
 listed on MOL.

 Most rules require a 3 minute maximum transmission unless other controls
 are available; what drives your need for such a long interval?  Just
 curious...

 Does anyone know how to lengthen a TLN 1361A T.O.T. from Motorola?
 The one I have is 1 minute, I need it to do 10-15 minutes.

 Thanks, Bruce KD4BOH.
