Topic: Can I fix my WR-300 Version 5?

[GTCountyWX]

Greetings!
I picked up a WR-300 Version 5 yesterday for $2. Not having any way to test it, I brought it home, and was severely dissapointed by the fact that it doesn't pick up the NOAA frequency near here. My other radios (a WR-120 and a WR-100) both pick it up just fine. Several people have told me that this is an issue with this version of radio. Is there any way I can fix it my myself, or should I  replace this radio with something else?
