Hi all
I am planning on adding a satelite receiver to my repeater system.
A friend has come up with a Motorola Maxstar radio that looks like it
may work at the remote site. Has anyone used this radio for this kind
of application? It will need to be modified to receive and transmit

I have had many requests to produce a mod for CTCSS Tone upon COS for

Here ya go:

The link is also available from the NHRC Index page on RBTIP:
Instead of baking soda, just dip/wipe the connections with Coke or
