Hi, Group. 3. Put a suitable light bulb in series. Measure the brightness with a light meter, then see how much DC or mains frequency current it takes to produce the same brightness. More easy way: t
Hugh. Quick and dirty way.... Fire up a 100W jap rig on 160 into a 50 ohm load. At full welly of 100W you should read 1.4A into the load. If the tx has a power meter or you have an external one in li
Hi Hugh, You don't say what other instruments you have available, but here are a few suggestions: 1. Measure the RF voltage across the dummy load with a scope. Determine current by knowing or measuri
Hugh, How have other people done it ? Any ideas ? I built a 1A antenna current meter with a current transformer. For calibration, I put a 10 ohm resistor (actually 10 x 100 ohms 1W in parallel) in se
Hi Hugh, two possible methods, one, put the power through the meter into a dummy lead, and measure the voltage generated across the load with a scope (easiest) or using an RF diode probe (but there i
