Bob,
I took a look through your program. Looks like it was a lot of work! It is very complete for the Las Vegas area.
In looking at Scan List #20 I noticed a lot of errors. Many places where you programmed the input frequencies just below the output. I can't think of this being useful, in fact it is a hindrance in this area. Your scanner may lock onto a unreadable signal from a mobile unit, while missing the clear signal from a repeater. You also have a lot of mislabeling and other errors with the federal, state, and local agency systems in Inyo and Mono Counties. I've been a Mono County resident for 28 years and travel in Inyo County including camping trips to Death Valley 1-3 times per year.
I don't have the time right now to review your file in detail, but may have some time later today or this evening. I"m picking up a friend at the Reno airport late tonight and may be able to look at it this evening.
If you would like me to do this let me know, if not I won't take the time to do so.
EDIT P.S. I noticed you don't use the LED color display feature much at all. Maybe one frequency or talkgroup. I find mine highly effective and not at all like the bells and whistle feature I thought it would be. I've set up all my files with green for natural resource agencies, red for fire, light blue for EMS, blue for police, orange for state highway agencies, white for municipal services, and yellow for county and local roads/public works. Sometimes while mobile and even at my desk, I can't get a good look at the screen, but see the color and figure out what I just heard based on the color. When I have a frequency that I don't hear often or something I'm trying to verify I put a very long delay and a high-low alarm on it. I think all the "bells and whistles" features of the PSR-500/600 have been most useful.
