This is a working configuration in a 70-0520CWB chasis with 70-2959-1 extender and 
70-020355 control head (5 button), IE: no error codes.  It came to me off Ebay (JG's) 
and is an example of a working extender or repeater

This file is set to Public Service and set up for the extender on 148.6 (extender Channel),
46.00 on the main, Channel one.  Many other freqs are in the file but the key information 
is channel 1 and the set up parms for a working extender.

Input/suggestions solicited.  wb6wui@gmail.com  or  www.otwc.net/pub/STII-0520CWB/
