You could decode all tones, selectively leaving out problem tones 
(co-channel repeater).

Go to the repeater site and use a signal generator or 
some other means to creat a weak signal and key the
transmitter.  Then start shaking everything on the
tower.  Something ls loose and rubbing on something
else..  I ahd a guy wire problem when the wind would
blow.  The repeater was in a 6x6 foot building at the
bottom of a 100 foot tower.  The antenna was a station
master at the top.  The guy wires at the ground had
about 2 or 3 feet extra that were hanging loose after
the clamps.  Some of them were rubbing the guy wires
going to the tower.  Clamped them down and that solved
the problem.

Re: [Repeater-Builder] Repeater 'noise' problem

[Chuck Kelsey]

Does it happen when you turn off the repeater's 
transmitter?
 
Have you tried shaking the guy wires to see if it 
increases the noise?
 
Is there any loose metal anywhere around the site 
that contacts more metal?
 
Is there any foil-shielded coax in 
use?

Put up about three LTR repeaters with different talk groups and you'd have 
a free repeater for every conversation on two meters.

RE: [Repeater-Builder] WAV forms to Courtesy Tones

I have a CAT-1000 controller and using the

Having homebrewed several of my own controllers, I have done
exactly the thing you are asking.  There are some limitations but it will
depend mostly on two factors: 





 





1) The complexity of the wav file you are trying to imitate.





2) The abilities of the controller you are using.





 





Personally, I would have to hear the wav file and know
the capabilities of your controller and with that myself or someone here in the
group who knows the controller you are using could more than likely help you
out.  





 





Good luck - and 73

I have a couple of wav files which I would like to try and use as a

I would like to try and somehow get the tone pattern for the wav file,

Anyone got any ideas

[Repeater-Builder] Repeater 'noise' problem

[Rick Stoneking]

All,
 
I am trying to resolve a problem on a local 
repeater where they are having intermittent 'noise' problems.  

 
Background:
This a commercial GE repeater that has been 
modified for 2m use.  When the noise is not present the repeater 
performance is outstanding with a wide coverage area.
The following have been replaced with new and had 
no effect:
  - tranmitter/receiver
  - antenna (super station 
master)
  - hardline from duplexer to antenna 

  - repeater controller
 
The noise may be related to weather (wet or cold 
causing an increase in the problem) though it is not a everytime event.  

 
It was originaly believed that it was a grounding 
problem but grounding improvements have had no lasting effect. 
 
At one point it was said that the guy wires were 
causing the problem so the club recently put insulators in all 9 guy wires about 
6 to 8 feet from the anchor point - no help.
 
The problem, which sounds like static or popping, 
occurs only during transmitting incoming audio.  In other words, all 
controller generated audio is fine, no noise what so ever.
 
I am wondering if we are looking at a problem in 
the duplexor.  One because it is the only peice of the system that has not 
been changed (although it was checked out by a professional RF engineer using 
state of the art equipment about a year or so ago - but he was just looking to 
tune it to the right frequencies).  Two, because the only time there is a 
problem is during transmitting received audio.  We are going to go and

To be fair, I've had an old-timer school me once or twice. I got to 
talking with him about a 25+ year old two-meter radio and the problem with 
CTCSS and he told me that he fixed that problem already. With two 
transistors and some parts, he built an astable multivibrator on 100hz and 
got into the repeater just fine. Sounded a bit off, being a square wave, 
and a little hot, but it did work and didn't cost more than $5. 

As far as the modern concerns of a high-RF enviroment, I think a lot of 
people have a lot to learn about radio in those enviroments. Some people 
have made sucessful careers engineering it alone, so you know it's not the 
easiest racket out there. 

And the FCC narrowbanding every other service is just going to make things 
worse.

You could set it up so that the 100hz decoder didn't enable repeat...
This would encourage the folks to dial up the correct tone...
Just wire the 100hz decoder's output to a digital input on the controller,
and program it so that when that input goes from active to inactive
the controller says "Welcome to the area - the PL tone on the
(insert callsign here) repeater is 131.8hz".
Or if your thinking is to use minimal airtime, just say "Use 131.8hz"

[Repeater-Builder] Re: Requiring CTCSS, etc.

[Al Wolfe]

At least the Illinois Repeater Association has not caved in to pressure 
requiring coded squelch on all Illinois repeaters by the end of December, 
2005. Non-compliant systems will not be de-coordinated but will receive no 
coordination protection from those systems that are compliant.

Another thought, in regards to the itinerant mobile, is the "PL100" 
concept where a repeater receiver responds to 100 htz. as well as their 
normal tone. With this system any transient could access any "PL100" 
compliant system by transmitting the universal tone of 100 htz. A 
distinctive tail message or other mechanism could be used to discourage 
common usage of the "PL100" system but still allow the sytem to be accessed 
by anyone with a need. Base stations would be dicouraged from ever using 
"PL100".

A couple of diodes and another tone decoder would be all the hardware 
required in most repeater system to implement this idea.

You could just buy a new antenna and be done with it.
RFS builds two station masters 220 to 225
the good old stand by DB-224 I think it is the JJ for 220 to 225 and many
more fine antennas are made for 220 Ham use.

Re: [Repeater-Builder] 220 repeaters

[Mike WA6ILQ]

There's some 220 Micor stuff on repeater-builder.com
on the Micor page  not much 220 antenna stuff however...
but you could build a WA6SVT Colinear for that band (see the
antennas page).

Re: [Repeater-Builder] another tech type of question

[Wade Lake]

  As long as the band you personally are using is in the service you are
licensed for then all other transmissions resulting from other links etc.
are the responsibility of the control ops.  If a control op is present when
this happens, this is totally legit.  If a control op is not present then I
would be inclined to think that the fault would fall on him for allowing
this discrepancy to occur on his system, as long as the unauthorized access
was not initiated by you.

 I would not allow such a link to be active on my system unless I was
personally monitoring the activity.  I suspect that this is the case with
most systems.  The way I understood this senario was that the most important
factor to you is the band you are using to access the system.  In the case
of IRLP/ECHOLINK  the situation may be a little more grey but if it is
advertized as a 440 repeater and it happens to have a remote base running or
other out of band link that you are not aware of, then I would not be too
concerned, simply explain to those who may tell you that you are operating
illegally that you are going into the system on the appropriate band and any
linked frequencies are unintentional.

Re: [Repeater-Builder] WAV forms to Courtesy Tones

[Wade Lake]

Having homebrewed several of my own controllers, I 
have done exactly the thing you are asking.  There are some limitations but 
it will depend mostly on two factors: 
 
1) The complexity of the wav file you are trying to 
imitate.
2) The abilities of the controller you are 
using.
 
Personally, I would have to hear the wav file 
and know the capabilities of your controller and with that myself or someone 
here in the group who knows the controller you are using could more than likely 
help you out.  
 
Good luck - and 73

Re: [Repeater-Builder] Requiring CTCSS

[Neil McKie]

  Good story !! 

  My 2 meter repeater was co-located with two high-band paging 
 transmitters that were 630 kHz apart.  After hearing the occasional 
 burps for years, I added CTCSS and never looked back.  

  It was either ask the paging transmitter people to move (I liked 
 the money) or shut down the repeater.  Neither was a good option.

Re: [Repeater-Builder] Requiring CTCSS

[Kevin Berlen]

On one of the systems that I take care of, we fought interference from a 
paging transmitter for about 12 months before making the choice to go to PL 
access full time. In our case, the signal was weak enough that a mobile on 
the fringe of our coverage area could cover it, but strong enough to hit 
the receiver and bring the repeater up. We tried different receivers, 
additional cavities, etc. until the only alternative was to take the system 
down or go PL. In some (perhaps most) situations, despite expending a great 
deal of time, energy, and expense, the only workable solution to solve an 
interference issue is to go to tone access.

Incidentally,a properly implemented PL tone decoder will detect subaudible 
tone before the squelch circuit in your receiver will unsquelch. This 
should have the effect of slightly increasing your talk-in range compared 
to a non-pl repeater. 73,

 A ha, the Mexican reverse burst. AKA Chicken burst.

All kiding aside, this IS a good method to force the user to have 
his/her radio in carrier squelch to monitor the channel for traffic.
And we would soon know who had the PL Disable bypassed Kerchunk,
