Hi Joe.... I am not really familiar with the 404 except what I have read on the Rat Shack site.... You won't be able to monitor the Madison County TRS nor KSP with the 404 but it should do the conventional VHF freqs in and around Madison... Are you in KY or GA?
Joe,
I Also just Purchased A pro-404. Now, Have YOu Ever Owned a Hand-Held Before? I Have Owned One And If YOu Havent There Rwally Hard To Figure Out, Trust Me But If You Have They Should Be The Same.
