Well my first thought is where did you get your frequency information? Ham repeaters are not always active (best time to check is the drive times to/from work), but certainly the local weather channel should be OK.
Since you're in Calvert county, here are our listings...(links are always blue)
Calvert County, Maryland (MD) Scanner Frequencies and Radio Frequency Reference
Go to the bottom of the above for the trunks in your area...
Calvert County Trunking System, Prince Frederick, Maryland - Scanner Frequencies
(note that the local trunk is rebanded so you would need updated firmware to trunk it. Unless you knew this, I'm willing to bet that you tried to use the old frequencies which, of course, are no longer valid)
You cannot hear BG&E or the FiRST system - that radio won't copy these formats.
K3CAL Calvert ARA Repeater Note: Put in the higher of the 2 freqs
NOAA Weather Radio
Did you try plugging in an earphone? If you heard something there, that just means the speaker is shot. Did you try a better antenna? A duckie (what normally comes with handhelds) isn't particularly efficient as you go lower in frequency.
Try to eliminate the obvious before assuming the worst...Mike
