Anyone remember this one, Radio Shack Realistic Pro-43, still have mine, great for aircraft reception and other VHF. Display is getting a little old but still readable.
Most keyboards of this type are resistive pads operating on PCB traces, usually using the rubber keymat as the spring. When they start to misbehave it is usually caused by wear or dirt on the pads and traces so a simple clean with isopropyl alcohol often helps a lot. Sometimes the wear is excessive but the resistive rubber pads can be refreshed using carbon paint with good success.
I still have mine but it does have the dreaded keyboard issue - I really need to carve out some time and see if I can clean as outline above. It was one of the best RS handhelds of all the radios I own (and owned)
