Huh? When were they not legal? W6MEP's repeater was on in 1956.

Maybe your friend didn't have a control link?

I still have the R-100 repeater for sale  462.725  DPL 125 
$100 and shipping cost.

  Lots of so-called dealers out there who do not know what they are 
  doing.

  Also you do not need the TS64 as the radios have a very capable

  Also check, MOST repeaters built from mobile radios are not type

I have seen these used as simple controllers many times for GMRS lashups.
This device DOES include a programmable TOT setting. So, if you don't need
an ID'er, or care for hang-time (and many GMRS owners don't need either of
these), then the TS-64 should work perfectly fine as a "controller". Of
course, I wouldn't use one in an Amateur Service repeater. BTW, the PTT
output of the TS-64 is a BCX56 NPN transistor, rated @1A Ic, so the earlier
comment about PTT current might be relevant, if the rig being keyed pulls
more than 1A on the key line (not likely). My bet is on desense in the
repeater system itself~Steve> KB4OID

Nope-it's just a newer version of the TS-32 CTCSS decoder. It is NOT a 
controller of any kind.

It can be used to drive a circuit that keys the transmitter and provides 
TOT and hang-time. And you're right, GMRS repeaters don't HAVE to have 
an ID'er, but it's a pretty good idea.

I agree with Ed's recommendation that this might be simple desense.  If 
the problem only happens on weak signals, your duplexer/antenna system 
isn't providing adequate TX/RX isolation.  It's likely the repeater is fine.

You might share what kind of antenna, feedline, duplexer, and 
interconnection cables you're using on the system.  Folks here will 
share their experience regarding those items, which are often more 
important (and also often more expensive) than the repeater itself, in a 
properly engineered repeater system.

To do a quick test for major desense problems, if you agree there's only 
a problem on weak signals (otherwise, the problem is likely to be 
something else entirely):

Turn the receiver radio on only, leave the transmit radio off.

Listen to the local speaker on the receiver.

Have someone help you by transmitting a weak signal into the repeater's 
receiver radio, down into the noise quite a bit, where you can still 
understand them, but they're very noisy.

Another thing that could be happening is desense of your receiver by 
nearby transmitters, and/or mixing products.  You need to describe your 
site location a bit for anyone to have any thoughts on that.  Those 
radios you're using don't have very good front-end filtering.

Okay, so to characterize some of this to see where your problem really lies:

Have them transmit and hold, and listen for a bit to the overall noise 
floor.  Is it changing?  The person on the other end should be using a 
fixed antenna and you should be listening to see if their signal 
strength is going up and down, or worse, they're getting "wiped out" 
regularly.  If they are, you're fighting other nearby transmitters 
desensing your receiver, or similar.  You will need at least a bandpass 
filter cavity on the receiver to save it from its own lack of 
selectivity or a more selective receiver.

If their signal is pretty steady and no major changes are happening, 
have them continue to transmit as you simultaneously turn on the 
transmitter of the repeater.

If the repeater's reciever loses their signal at this point in time, or 
starts to chatter on/off.  You have a desense problem in your own 
repeater system.

Perhaps you used cheap interconnect cable that's leaking badly, perhaps 
you used an antenna that doesn't duplex well, perhaps your duplexer 
isn't rated for the power level you're using, or ... well there's a lot 
of things.  Do the test, send more info.

Of course, you can also do this with proper test gear much easier than 
this, as well as it's a good opportunity to measure your usable receiver 
sensitivity (including site noise) at your site, if you can borrow 
someone who knows how to run it, as well as the test gear itself.

If you don't feel like doing this level of troubleshooting, see if the 
shop you bought the repeater from has installation/troubleshooting services.

Otherwise, let us know on the questions above... we'll try to keep 
guessing from afar.  (It's far more effective to just hook up real test 
gear and find the problem, but sometimes you don't have that option, so 
the mailing list has to be "good enough"... and you'll end up making 
multiple trips to the site and wasting a lot of time.  Time vs. money, 
just like everything else in life.)

You mentioned this occurs when a 'semi weak signal' is heard. Does it do 
the same thing if an extremely strong signal (someone keys up right 
outside) is present? If the problem only happens with less than very 
strong signals, you are likely getting transmit energy into the receiver 
from inadequate isolation within your antenna system. If it does it on 
all signals (weak or strong), an earlier post mentioning excessive PTT 
current is likely the problem.

Not the first, but one of the 1st (maybe 2nd?) & certainly the most complex 
of its time:

http://wa6tdd.tripod.com/

Between the audio processing & circular polarized antenna, it was perfectly 
copyable all over the LA basin on an old deaf multiband 
(AM/FM/shortwave/VHF) receiver.  Remember these things only had a wideband 
FM receiver.

RE: [Repeater-Builder] TS64 as repeater controller

[Juan Tellez]

What you need from what I understood from your post is to add a delay to the
PL detect and you will

resolve your problem, but the TS64 is not a controller, just a
encoder/decoder.

 

Juan Tellez, XE2SI

 

 

Re: [Repeater-Builder] TS64 as repeater controller

[mch]

It is. They are using the decode logic line as a PTT for the TX.

I would say it is not connected to a good decode point or your TX is
drawing too much current from what the TS-64 can supply.

Re: [Repeater-Builder] TS64 as repeater controller

The ts64 is a tone decoder. Not a controller.

[Repeater-Builder] TS64 as repeater controller

[fxbuilder]

We purchased a uhf repeater from a local SoCal GMRS dealer and have
had problems with it's working correctly since we purchased it.  The
controller is actually a ComSpec TS64 and the 2 radios are 4 channel
maxons.  The white wire (rx audio mute) is used to drive the PTT on
the transmit radio.  What we are finding is that it doesn't keep the
repeater in transmit mode, it stutters. Semi weak signal heard by the
receiver (almost a clear signal) will cause the transmitter to cut in
and out or not work at all.  We asked for help from the dealer who
promised a new controller but never has delivered (its on the test
bench). Anyone have suggestions on what might be causing this problem?
 Is there there something we need to put between the comspec and the
mic ptt line? Or is the ComSpec bad?  A different controller could be
a possibility but not really in the budget (especially when the dealer
said they made a ton of these and they all work great).  What are we
missing?  This is GMRS so no Iders required.  Thanks for the help.

[Repeater-Builder] Re: First repeater?

[tallinson2]

Have no idea how this ranks but just FYI WB6AAE, Grizzly Peak, 
California (SF Bay Area), 146.2/146.8 was up and running when I got my 
license in 1962.  Around late 1963 or early 1964, added a UHF repeater 
on 449.5/448.1.  Sponsonred by Grizzly Peak VHF Amateur Radio Club, 
Richmond, California.  Several other repeaters were also up and running 
at that time including K6GWE (I think it was K6), an AM repeater on the 
San Francisco peninsula.  I don't remember the city.  Also a couple of 
others in "General" portion of 2meters (144 - 145 and 147 - 148)  I was 
Tech. at the time so don't know too much about those.  Interesting 
project.  Hope you get lots of information.  Will be following this 
with interest.

Hmmm-there must be a few errors in there about the exact band segments. 
The first FM repeater here was a RACES machine down in the 145 segment 
(different rules), but the first non-RACES repeater was 146.34 in and 
146.76 out, circa 1968?, next was 146.46 in and 146.82 out in 1969, 
right after that was 146.88 in, 146.40 out (that's right!). The .76 
machine was 'whistle-up', the other two were carrier squelch.

Also the UHF repeaters that I know of were 449.0-449.95 in, and 
447.0-447.95 out.
