Hi everyone,
This is probably the second time I have sent a question to the list, but read
all e-mail of interest from the list and it covers a large variety of
interesting pic subjects.
I have a project I am working on which uses a pic, which is initally sleeping
and powered up by an interrupt at RB0. It then is awake for 2 minutes and
looks for an interrupt on RB7 ( RB0 is used to wake up from sleep). When this
occurs a different timing cycle starts and then output RB1 turns on.  The
timing and interrupts work great. Now my question. I want to initiate the RB7
input from an RF source at very short range (10 ft max) . Most of the RX-TX
modules I have seen are for .100 ft.(Linx or Ming for example) I want the
circuit to function when the circuit (battery operated) comes near the
transmitter.) The transmitter will be line powered.
I can sure used some suggestions-ideas.  I have thought about frequencies as
low as one khz but alot of power is required.
Thanks in advance.
