Many years ago (decades ago), I worked in an electronics test lab. Any piece of test equipment that didn’t have a recent calibration date on it was labeled “for reference only” In most cases “for reference only” is just fine. Calibrated instruments are needed when working out equipment specs you’re going to publish in sales literature.
I just use 2 germanium diodes and 1 small capacitor across a 50 microamp meter with a short wire for my field strength reading.Relative readings i know so i tune up for maximum indication on the meter when im operating portable with my random wires. Great channel as always Dave. Happy new year to you and all who watch this channel. 73.G7HFS/PA3IKH
Dave: FSMs (and receivers) measure the strength of the ELECTRIC field in units of V/m where m is the “aperture” (AKA: length) of the antenna cutting through the electric field to produce a voltage proportional to the field strength (usually rectified for the sake of a steady meter reading). This E field decreases with distance between the transmitter and receiver as 1/d and NOT 1/d^2 which is the POWER degradation rate. This explains why we can receive E fields far away but are challenged to transmit actual energy wirelessly at anything but very short distances (eg-wireless phone chargers)

Don’t the two laying down have a different antenna polarization?
What about the RF meter app on your cell phone?

Where is the review of the Tidradio ? Would like to see that...
Search my channel for tidradio
