- I need concise schematics for small, low-power RF transmitters
- (preferably FM). I have a basic knowledge of electronics and am handy
- with a soldering iron, but I really need these circuits spelled out
- for me. I would appreciate transmitters powered both by batteries and
- by phone line current (while still allowing normal operation of the
- phone).
- Recently, I also rec'd a cellular phone that I have no use for
- as-is (can't afford to subscribe), but is otherwise in perfect working
- order. What can I do with it (other than using the battery, etc.)? Can
- I program it to listen in on active cells, switch cells to follow a
- call, etc.?
- Thanks in advance--leave all replies here.
