The link you posted is to a Trunked Radio System (TRS). To learn mor about trunking, check this out.

About 1/2 way down the page on the far left side of the table there are the letters DEC and MODE what do these two things mean?
When mode = A, it means the audio is Analog. When mode = D, it means the audio is digital. When mode = E, it means the audio is Encrypted. Encrypted audio can not be received by any scanner (because of laws prohibiting it).

The DEC column indicate the TALKGROUP (TG). This is essentially a "channel" on the TRS. It works like an old phone PBX system. A lot of users share a small number of frequencies. Users are identified by User IDs, and the channels they are on are called TGs. These are typically programmed into your scanner. The exact method of how they are programmed is dictated by the exact scanner you have.

Yes, for your Pro-94 you must enter all freq.'s.

I had a look at the Leon's Radio link you posted and it is an LTR system that a Pro 94 won't trunktrack. :(
Sure, you can listen in, but the talkgroups will not appear.
