It may be a simple fix, but if you need repair, here's a contact for Standard repair:
Matt Adrian KD8ZB
SAR Technical Services
1792 Nash Drive
St. Joseph, MI 49085
I haven't used his services, but I believe he was a Standard repair tech, and has a lot of parts. He may be your ONLY chance for a repair. Good luck. I have three Standard radios (a mobile and 2 H-T's) and pray they never need repair.
