I started the thread about homebrew wireless com systems using cordless phones a while ago. There are a lot of comments and questions here about com systems so many of you may find this interesting.
As I was browsing about yesterday I found a site called ComClone the URL is
http://www.rcrowley.com/ComClone/ and it seems to have directions for building your own ClearCom compatible com system. I have not tried this so your mileage may vary, but it looks interesting. More information on various
intercom systems is availible at
