Just insert a sausage in there. A sausage is meat with skin around it.... a finger is the same thing.

Why won't my Realistic Pro 2020 stop scanning

You might have the squelch turned up too high so the broadcast cannot break the squelch open. Here's an instruction manual (with how-to) for your scanner. Seems easy. Also make sure you have a good antenna so you can pick up signals.

Will Realistic Pro 2021 receive digital frequencies?

If it does not say digital on the scanner the answer is no. If it does, most likely it is a trunking system and will require programming using software and a computer.

I have a Realistic Pro 2021 and it doesn't pick up no channels, and idk how to program it please help.

your scanner will have to have some crystals put in it that are specifically for the signals you wish to scan. go to any radio shack store or scanner store with your scanner and they will gladly assist you.
