RC-Mon: R/C Frequency Monitor Project

Recommended Posts

The full details on building a low cost R/C Frequency/Interference Monitor are now online. It uses a retired Hitec Feather Rx, a $13 Radio Shack Mini-Amp, and some music wire. It can hear R/C signals up to a mile away!

This project will also work on the following low cost R/C Rx's:

GWS GWR-4P

Hitec 536

Cirrus MRX-4

Like the Hitec Feather used in the project, these all use the MC3361 demodulator IC. The Speaker amp would connect to Pin 9 and gnd.
