Okay...okay. I'll try being helpful. If you want something that will listen to cordless phones and drive thru's than a basic scanner like the one you posted a link to, will work. If, however, you want to listen to local emergency calls and whatnot, you will need a trunking scanner. As for the 1.3 and 2.5 ghz phones...you cant listen in on them as they tend to frequency hop.

Old cordless phones that operate in the 49 mhz range are still audible though.
