I wonder if the best route would be to use a regular baby monitor
transmitter - but use a better receiver and/or receiving antenna? Like a
decent scanner, possibly with an attic antenna. This method is easy to
accomplish even for someone without electronics experience, and
unquestionably legal, unlike many other alternatives.

Unless the OP intends to use it for covert evesdropping, hence the plan to
make the battery last longer. 1000 feet is a long way for a baby monitor to
be needed that would be on the next block in most cities.

Asking in an amatuer radio newsgroup (where the goal is often increasing the
range not decreasing it) might not be the best source of info.
thanks, John.
