Picked up two cbs today at a yard sale for $10. One is a Cobra 21 the other (which caught my eye when I saw the clarifier knob) is a RS TRC-485 w/upper and lower side band. I brought it home and cleaned it up wired it up to a power supply and it appears to work fine. Clean display .... clean overall after a thorough wipedown. I want to ask you out there what your thoughts are on the 485?
