Digital Card

Can "tell me what this "tapping" thing Is?

A discriminator tap is an audio connection that runs from inside a scanner to a PC's sound input (the mic or line in jack). It lets the PC do things like decode control channel activity or emulate a digital card. Here, you can hear the analog-only scanner grinding away while the PC (nearly any Windows PC will do) synthesizes the digital voice traffic:

A tap also lets you go well beyond a digital card, as it also lets you decode DMR/MotoTRBO and NXDN traffic, which are becoming very common and no scanner to date will touch those digital voice formats, nor have any been announced.

Nice video! I have a BC-780XLT that I do the same thing with... When plugged into DSD+ it makes a great digital scanner! Many thanks owed to the author of DSD+ for sharing his excellent software....
