Ron’s Lockdown project

Post by RON »

Here is a little project I’ve built. It’s a field strength meter for amateur radio use. Uses a 20x4 oled screen and an Arduino Nano.
It displays the presence of a strong RF field. It’s very wide band and covers 1.8 to 500Mhz. Possibly higher.

Brilliant Ron, very handy - I'd be interested to see the circuit, does the diode detector go directly to an analogue input? and the power on/off code - spill the beans :D
You could use microwave diodes like 1SS99's for a 2.4g field strength meter :D

Also - announcement - huge congrats to Rons better-half Kerry who has just aced her Radio Ham exam and has a very special callsign - M7KEZ !!! :D
