NEED COMMUNITY REPEATER PANEL....

RADIONET · Post by **RADIONET** » Mon Sep 20, 2004 5:31 am

I am looking for a community repeater panel that works.
I've tried the Motorola I20Rand ZR310, both sucks.. They take too long to decode.

Please help.

What are you trying to decode ? DPL or PL ect.

What repeater type of equipment are you using it against ?

I do have a CSI32 comunity repeater tone panel that will do the standard PL (CTCSS) tones .

It is at the moment configured for any Motorola radio with the 16 pin option port on the rear of the radio.

The 16 pin plugs are on the CSI32 panels wiring for simply plugging into the radios 16 pin port.

Its almost a plug and play type of setup.

I kept it around as a emergency get the tower back on the air type of thing but just have not had to use it very much = Thank Goodness.

You use one radio for the tx and another for the rx and program the needed PLs wanted .

So what ever the RX radio is programmed to rx it then recieves its freq and the panel validates the incoming rx and if valid PL it then txs the TX radio at what its programmed to TX at.

This works with for examples the Motorola GM300 or a Maxtrac or a Radius M216 or even the M120 . ( If its a Motorola with the 16 pin option port your good to go.)

Do have the Manual for it and its working .

PM me if its what your looking for.

Odd, I have had good luck with the ZR310. Just out of curiosity, how fast are you looking for it to repeat? I have had other customers who complained that their new kick a$$ repeater was not as fast as their old simplex system.

some delay is normal. so what kind of results are you getting?

The ZR310 is faster then the I20R but not enough.
I have tried to program a longer pre time for the MDC but that really anoys people.
So I was wondering if that was something better, if doesn't so I will have to live with it.

Also both of the add something like 10db loss to my receiver.

Tks,

I have experience with both the CSI and Zetron repeater controllers, and both are easily fast enough to decode tone in time to capture MDC so long as the pre-time is set at a reasonable value (250-300 ms min.). And no controller should affect effective receiver sensitivity if properly aligned. I think you have an alignment problem.

Umm. How is something connected to an audio output of the radio effecting it's RF sensitivity. The controller has nothing to do with the receiver, antenna, or anything else that would cause loss. Something else is wrong.

If you are trying to pass MDC and it's not fast enough, why not just program the MDC to post transmission? Also about the sensitivity loss, sound like you have the squelch set to high on the panel, you are better off using the squelch control in the radio. What type of radio are you interfacing with?

What I think is a mismatch between the recovered audio voltage produced by his receiver and the audio voltage expectation of his controller board. This can give the appearance of a signal that should be strong enough failing to break squelch.

G'Day from Downunder,

This reply is a bit late but what the hell.... why not, it may help someone!

I know with the ZR310, if your RX audio is not "flat" decode takes for ever!

I have a GR300 here with the ZR310 contoller. In the RX radio - GM300 jumper P551 was set to De-emphasis/muted audio! which filtered out anything below 300Hz i.e. CTCSS/TPL/etc.

Jumper P551 must be in pos 'A'! not 'B'... You need to have flat unmuted audio... no de-emphasis or other filtering running to the controller...

De-emphasis is done by the ZR310 along with a 300Hz High-pass filter for the voice side of things!
