I have an older realistic pro 2025 that the receive has gone dead on. It turns on and scans like it should, but it won’t even pick up the weather stations. I know my antenna is good because my other 2 scanners work well on it. Where would I begin to look to repair this? I know it’s not worth having it fixed, but if I can do it myself I would Ike to have it working again. Plus I’d have the experience.
