Programming all 18 radio presets automatically

[Semi-retired]

Has anyone "dug deep enough" into the radio on 2nd gens to determine if you can auto program all eighteen FM radio presets without encountering "duplication"?

 

I've tried a couple of different sequences of selecting Band 1, Band 2 and Band 3, and going through the a/b/c/ automatic channel writing steps......but I keep getting some of the same stations appearing on more than one band.

 

Suggestions?

(Please don't say "buy a satellite rig" :-)

I tried to do that and pretty much concluded "no"... :-(
