[Motorola] Re: Request Information on C63RLB7106B

[Doug Eaton]

Tim,

You have an MSF Limited. (It replaced MSR2000 when it was cancelled)
It is an MSF5000 that was sold with a limited option list.
Once in the field it can do anything an MSF5000 can do.

Since it was used for paging, does it have the Binary paging Option?
Look for a Binary Paging Module in the expansion tray.
If it does have this option, do they want to continue using it for 
paging?
And if so _DONOT_ attempt to change the channel structure of the 
codeplug.
It requires very specific attention to codeplug structure and also has
special Codeplug patches in both the SSCB and TTRC boards.

Contact me directly if you have any particular questions.

Hello
I am trying to figure out this C63RLB7106B "MSF Limited". It is 
connected by wire line control to a Centracom 11 console. I am 
confounded by the receive and transmit arrangement. It has (1) receive 
port and (2) TX ports, one on 154.250, and the other on 152.0075. Is 
this set up as a repeater or as two channel "Base"? Each of the TX 
ports is fed to a TX-RX Dual-Section Isolator, and the Isolator is fed 
to a band Rej. cavity (of opposite fx, of course), then each fed to a 
band pass cavity, which is fed to a common antenna. The Rec. 
port(154.250) of the radio is connected to a relay, which is connected 
between the output of the isolator (154.250), and the input of the band 
reject.

The radio appears to be programmable (Has channel mode key), a red LED 
"Status" window, and a "select"/"Set" switch. (It reminds me of the MSF 
5000).

Our task is to add another frequency pair to the radio system (159.000 
rec./154.995 xmit). I can't see how we can do that, when the cavitys 
are tuned for a descrite frequency!

This radio system is a fire dept paging system, and used for "local" 
comm. Do appreciate any help, or advise.
