Yesterday I picked up an older 1995 Bel 745STi at $10. Fun to fool around w/ and here are some of my observations from having it plugged in at home and not in the car. I get random x band alerts when there are no x band signals in my living quarters. Weird. I checked to see if my cellphone was causing an of the alerts and it wasn't. Last night while having it plugged in near a cable box that was off, it falsed on x,k and laser. Laser only went off a couple of times. I checked it w/ some of my equipment and the ramp up is a little different especially when using my Stalker ATR 34.7 handheld radar gun. The #'s on the display really jump all over the place. Funny thing is I don't see this w/ todays V1,Bel,Escort, or Whistler rd's. I have to LOL at that old Bel 745STi. It came w/ the original box but no window mount or power cord. Good thing I had a power cord and device that plugs in the wall w/ a lighter end on the side to check it before I bought it. I would like to hear about other's experiences in the past w/ the Bel 745STi.
