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.

Re: Ron’s Lockdown project
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
You could use microwave diodes like 1SS99's for a 2.4g field strength meter
Also - announcement - huge congrats to Rons better-half Kerry who has just aced her Radio Ham exam and has a very special callsign - M7KEZ !!!
Very well done Kerry, enjoy your new hobby!
Cheers
Phil

Thanks Phil,
Its a very simple front end and yes it goes straight to A0.

Here is the sketch for the FSM.
