Pretty cool huh? Of course I would not use it for phone intercepts, but it sure does work well at a ball game to hear the coaches communicate.
PS: Everyone has digital scanners now, so security requires encryption. Do you have an encrypted phone?

Cool scanner
Yes. I use cordless phones that have DECT 6.0. There are about 5 common manufacturers (well, branded by them) Panasonic, Uniden, AT&T etc.
They are inexpensive. The encryption is not that great, but it works. I used to work for a core networking company that sold telecom equipment to the government. They wanted encryption better than FIPS-140-2. All the hardware and software we made could not be exported out of the country.
Not to get off topic;
One thing we used to do back in the 80's (and it still works today), is that if your scanner or any radio does not have a suppressed local oscillator on the analog receiver portion, then your antenna radiates just a little bit of the LO.
We had (really expensive) spectrum analyzers where I worked, and we could tell is someone had a radio on nearby. What was better, is that we put up an antenna pointing into the parking lot, pointed it at cars, and if they were listening to FM, we could tell what station they were listening to
