RE: [Repeater-Builder] 6 meter repeater Identification and help

Travis,

The Motorola Reference Manual describes the B61LPY-3100DT as a Repeater (RT)
Station for the 25-50 MHz band.  It is rated as 100 watts continuous duty,
with Private-Line squelch and DC remote control.  The service manual for the
station is 6881003E65 which, unfortunately, is long out of print and not
available from Motorola Parts.  You may be able to locate that manual on an
auction site. 

Armed with the service manual, you should be able to convert that station's
receiver to the 6m band by changing out some capacitors in the front end and
local oscillator stages.  The transmitter section will take a lot more work,
but it can be done with the appropriate tools and test equipment.  You might
consider contacting a firm that specializes in such conversions for
suggestions and cost.  Repeater-Builder (the Company) is one such firm.

The Sinclair R-103G duplexer is a very good unit, but it will take some
serious sheet-metal work to make it perform well in the 6m band.  The
conversion involves shortening both the outer cylinder and the internal
elements, and changing the cable harness.  You might consider contacting
Sinclair tech support for suggestions, at www.sinctech.com

Although they are somewhere around 30 years old, such Motorola stations seem
to keep running...

Hello group,

I have four Motorola repeaters in the 48-49 MHZ range.
The fifth is high VHF.

1) Can anyone tell me what they are?
2) Any leads for information or people that might know how to convert 
the equipment for ham use?

The repeater model is B61LPY 3100DT SPL (it looks like)
The duplexers are model R-103G 

Pictures are posted on my site:

Any help would be greatly appreciated.

Thank you,

The repeater is a 120 watt continous duty Motrac with factory PL and no
extender, I think.

The duplexer is a exactly what the label says.  I have had one operating on 
6 meters for about 15 years.  They need slight modification to go to 6
meters.
