I noticed when programming my Radio Shack Pro-106, that the ARC 500 was setting the bandplan to Canada, is there a way to change this in the software, or is this something I have to keep changing in my scanner? Thanks.
You could do a reset, as described on Page 86 of the manual. Do the one that resets only the scanner settings and does not clear your data. The last resort would be a full reset, but that is going to clear everything. If this scanner was originally sold in Canada, it may be the default setting, in which case the reset will not change the country setting.
