A web search for your model turned up a blank. You aren't kidding about having it for years. I'll give you some generic information about AM radio reception and hope you find something useful.
Generally, AM reception is through a wire coil wrapped around a ferrite (very fast magnetic material) rod. Received signal strength is dependent on the angle between the rod and the radio station's transmitter antenna, so rotating it in a horizontal direction (around an imaginary vertical line through the center of the receiver) is often helpful. The angle of the best direction can be affected by nearby equipment (metal appliances, ductwork, computers, etc.)
Many non-portable audio receivers and a few boom box types have both an AM and and FM antenna terminal on the back. The FM antenna is very much like a TV antenna (you can use a TV antenna) and is generally required to get FM reception except in units with a telescoping antenna mounted to the case. The AM antenna is used to augment the coil signal, and is generally needed only if you are trying to pick up a weak signal. Attaching a wire to the AM terminal may help (make sure you have a good electrical connection between the terminal and the metal of the wire). This wire will also have an optimal angle for best reception. Try arranging it vertically; many AM radio stations transmit vertically polarized signals for the benefit of car radio antennas.The longer the wire is, the better, but it doesn't have to be very large. The physical limit is about 110 yards, the practical limit is how much you can stand to have stretched out behind the stereo. (A thin wire going up the wall to the hook behind a picture will probably not attract much attention.)
Portable radios often use a single telescoping antenna for both AM and FM along with the internal coil previously described. If you have this, experiment with antenna position and radio location. I have been told that some early model LED light bulbs may interfere with AM radio reception, especially if they are within a few feet of the radio.

If you have the magnetic antenna, check it for a little nick on the cable on the outside of the car where water might get in to it. A little water can short the ground and the antenna wire. You also can wash (with lots of water around where the antenna cable is) and see if it happens again, then you will know it not just the weather

Your ONLY solution is an external antenna. The best scanner is only as good as the antenna that feeds it. A discone would be the best, but a less-costly vertical would probably do a good job for you. The least costly, and least effective solution would be an indoor antenna - the ones enclosed in PVC pipe do a fair job. If you can't mount the antenna on your roof, a balcony or an attic will usually work fine. As a last resort, you can always set up a vertical inside a closet. eBay is a good source for scanner antennas, and you might also try www.ScannerMaster.com.

It's a well known problem in DGTEC receivers - the AC3 / 5.1 surround sound isn't properly decoded. The 2 possible fixes for that is to either downgrade the output to 2.0 stereo or select in the settings for that channel the MPEG-1 decoding option if available. If this doesn't fix it you will have to do a firmware upgrade - or take the unit to a shop for them to do it.

Did you replace the antennea with the EXACT same one,or did you get an aftermarket one ? Did you replace/reinstall the rubber/plasitic gasket that sit's under the base where the antennea mount's on the truck ? If you answered yes to ALL of these question's,then your problem lie's in the cable itself. Be sure that you have the CORRECT one (cable) because where the cable connect's to the antennea there can be no play (looseness) or you WON'T get the proper signal.
