Precisely! That is why the cordless manufactureres went up from Lo Band, to Hi band, to 800/900, to 2.4 GHz, added in spread spectrum hopping. If you come across older models you can still hear em, and on the older model 800 MHz Radio Shack scanners, you can hear the 800/900 MHz cordless non spread spectrum stuff. And even though tecnically blocked the older model RS 800 MHz scanners did pick up the analog cellular stuff which used to piss me off when trying to monitor TRS back then.
