Greetings to listeners of the airwaves. In the last couple days I have really become interested in scanners and Ham radios mostly due to the fires here in southern California. I am trying to learn as much as I can about my scanner (pro-2096) and how to program it for my area. Several years ago I bought it and a neighbor set it up for me and the area I lived in. After a time it got packed away (various reasons) and with the onset of the fires I unpacked it and plugged it in ready with the manual to set it up to "evedrop" on the happenings for safety and just plain curiosity. Alas it was not so easy (all channels locked out) however in my search to figure out how to program it I found this vast wealth of information here at RadioReference.com. Even with the information I have found here I find myself struggling with understanding some of the terms and phrases associated with setting up my scanner. The glossary in my new ARRL Ham Radio Licence Manual helped but there are still some terms/phrases I am having trouble grasping for example channel vs talk group and tone mode (for some reason the usage makes me think it has a different meaning the the dictionary version of a vocal sound). So I am hoping to get some direction on where to find this type of information. Any assistance would be greatly appreciated.
