Subject: [Motorola] Looking for a couple Micor things
Message-ID: <569BE15D.1090703@att.net>

Hi All

Looking for two things:

First, a 12 channel Micor Control head, or just
the rotary switch from one to replace a 4 channel
switch.

Second, documentation on the 8 frequency System 90 channel
scan module.

Thanks!

Subject: [Motorola] Questions about RT and RA base stations
Message-ID: <56A7D7FA.80507@att.net>

The following deals with Micor base stations,
unified chassis control shelves.

How would Motorola interconnect two stations back to
back? What I'm thinking of is an RT and an RA.

(Think of a UHF to 6 Meter remote base).

I can see how the PTT interconnection would take
place using TB-3 on the chassis, but how is audio
done? Is it as simple as tying the two un-notched
mic hi connections on TB-3 together, or would the line
driver modules be involved somehow?

At this point I'm not too concerned about control
functions such as set-up, knockdown, frequency or PL selects, just
basic operation.

I can certainly figure out a way to do this, but
I'd like to know what the "official" method would
be.

Thanks

Subject: [Motorola] TU-255 cavity
Message-ID: <56ABA2E8.5060807@att.net>

I have a duplexer built out of 4 TU-255 cavities.

What are the specifications on insertion loss, and
is there any documentation on the cavity or duplexer
assembly. The cables between my units are obviously
not factory, and I'm wondering if they are the right
length.

I just tuned one up , and am seeing 3 db loss on
the transmit side, is this normal?

Thanks

Subject: [Motorola] OT: need Cushman CE-50A board
Message-ID: <56AD351D.8080606@nova.org>

Hello All,

Sorry of the off topic post but I thought this would be a good place to try.

I picked up a Cushman CE-50A at a hamfest today.  It is missing the last 
board (rear) of the right card cage.  If I read the manual correctly, 
this is the 39000 regulator board.   Anybody got a board from a junker 
they want to get rid of?
