Question: Are there any 'secure' cordless phones?? After reading the recent comparisons/comments/conversations around cordless phones I've not seen much on any models (nor have I found any* vendors) who offer some sort of secure link between handset and base (I.E. scramble, digitized, etc..) Since cordless phones are SO open, and you can bet that someone may be listening, I would consider this a BIG plus that could help a vendor succeed over competitors in the marketspace. Last summer's court case ( {Wall Street Journal} Aug ??) where an individual (while eavesdropping via scanner on a cordless) gained enough info to help get his neighbor arrested/tried for conspiracy (of all things) is definitely enough for me to want to search out at least a cheap sideband addon, or go back to the 500 foot extension cord. Any product suggestions, comments, insights are eagerly requested. [Moderator's Note: Back in my CB radio days many years ago, I used to frustrate the neighbors by talking on sideband rather than AM. They could still hear sounds coming from their television on channel 2 (and indeed, they would say 'it must be Pat on the radio again', but at least they couldn't understand what I was talking about! :) All they got were 'Donald Duck sounds', as any of you radio guys will attest who've heard a sideband transmission while tuned to AM. Too bad the cordless phone manufacturers can't scramble their signal or at least use lower / upper sideband, etc ... that would fix the majority of the snoops, although a dedicated person would tune up the ham rig and listen anyway.

I thought that there were several cordless phones out there that automatically changed the frequency every fraction of a second so as to keep the conversation somewhat secure. [Moderator's Note: These are available. I don't know about 'several' different models however. I think their cost would be / is prohibitive from a consumer's point of view. PAT]
