SCANNER REPAIR
If you have a scanner which needs repair, there are two good options:
Contact the manufacturer and send it to them. They have lots of experience making any repairs your radio may need, and the best possible access to any parts that may be needed.
Radio Shack: 800 843-7422 (they say take it to your local store to send it in)
Uniden: 800 297-1023 Monday-Friday, 7am to 4pm Mountain time. - GRE: 650 591-1400, 9am to 6 pm Mountain time
