Thanks, > Frank Matthews > Indian River High School > Chesapeake, VA 23325 You might check out the ARRL Publication call "QEX" - there was a simple 2M receiver project in the April 1991 issue. The receiver consists of 3 inexpensive chips and about 50 discretes. If you changed the discretes to through hole parts (author used SMD), it would make an appropriate project for a HS electronics class (at least we used to build things of similar complexity in my HS electronics class). It should be possible to tweak the circuit to cover the VHF police/fire, etc range. You can reach the ARRL at (203) 666-1541. Rick Spanbauer State University of NY
