SVR-200 and CM-300 Frequency set up

Post by ICEMANTIM »

Hello I have a question about the SVR-220 vehicle repeater. I installed our last night and i think i have a programming problem with the mobile. The units seem to talk together find about every other time the CM-300 we have it hooked to locks up the transmit and transmit a continues tone. If i turn off the svr-200 it resets and will work for one or two time fine and lock up again.
Here is what we have in the radios we are using

Mobiles CM-300
Freq tone
RX 158.7900 CSQ
Tx 158.7900 88.5

Portables PR-400
Freq tone
Rx 158.7900 CSQ
Tx 158.7900 88.5


The pins for the cm-300 are set up follows
Accessories set up

Rx Audio Type is set to (Flat Audio)

Pin 3 is set to (External Mic- Active Low)
Pin 4 is set to (PL/CSQ/Talkgroup Detect- Active Low)
Pin 8 is set to (Clear to Send- Active Low)

Everything else is what came from the factory


Any ideas the local Motorola shop did the testing and programming on the SVR-200 when they did the county wide testing.
I am guess maybe the radio programs need adjusted or the SVR-200 needs tuned closer.

Thanks for the help.

OK. Im confused but the portable and mobile cannot be on the same frequency, unless your talking to the SVR with a different radio ? What is the SVR supposed to do ? Normal set up on these systems are the mobile is on a dispatch channel and the SVR is on a channel to talk to the portable radio. Hence when user is in building the SVr talks to the portable when the dispatcher gets to the mobile.

I'm confused too. What frequency (s) is the SVR200 programmed to? If you are wanting the SVR to operate as a extender so your portables can use your mobile to repeat, the setup is wrong. Portables would have to have another channel provisioned with the SVR repeater channels.

Hello I am confused also because i thought the svr-200 should be on a different freq also like portable transmit on one freq and they would receive on the talk channel. The svr would be used as an extender go into the mobile and out the mobile on the portables receive. That way it would be going over the air at 50 watts not the 5 watts the portable puts out. The way the local Motorola dealer programmed them i am not sure how it works correct with looping on itself. They took the SVR today for retuning should get it back next week but i still think it’s set up wrong. The SVR-200 is programmed to receive 158.7900 with a 88.5 tone

What???? You're saying the CM300, the portables and the SVR-200 are all programmed as 158.790???
Noooooo! Please clarify!

Hello yes that's the way they programmed them. I questioned them about that when they set it up that way. I am not sure what is programmed into the svr because i don't have the stuff to do it, but the portable are receive 158.790 CSQ and transmit 158.790 with a 88.5 tone. The mobile hooked up to the svr is programmed with the same freq's set up as the portable. I would think the svr should be on a different freq of some kind or the mobiles can not transmit PL so it would not set up a loop and the svr would not receive the tone so it would not repeat the mobiles transmission.

That is correct. The SVR200 should be programmed on a separate simplex channel and be at least 2MHz away from any other normal operating channel in the CM300. The portables
can then have the SVR freq in them and go to that when 5 watts is not enough and utilize the vehicle repeater. In no way should the CM300 have the SVR channel programmed into it.

Call Pyramid. They can straighten this out for you in no time.
