Hi,
I have a RIM-Maxtrac interface (http://www.repeater-builder.com/products/usb-rim-lite.html) for sale. This interface is specifically made to interface with the Motorola
Maxtrac/Radius/GM300 line of radios. (see the link for a photo of the interface). I am asking 50.00 (that price includes shipping to the US only via USPS priority mail).
Please email me off list if you are interested.
Thanks!
Jim, K6JWN
