Right. It also reads peak power with decent precision. That's important if you want to be very competitive -- we are licensed for 1.5kW PEP, and readying that peak power accurately is important if yo

You could study N8LP's web page. Click on the LP100A link. It's worth it to me if it lets me run closer to legal limit in a contest, or when calling DX. 1.5:1 SWR causes significant error in the powe

Most less expensive meters only measure voltage. They calculate power as Voltage squared divided by 50. They always assume the load is a pure 50 ohms. But with a 1.5 swr, you could have a 75 ohm load

That depends on how the radio is run. Lab testing is done full power barefoot. Don't know the DC power supply voltage. IMD is significantly reduced by operating the radio from higher DC voltage (13.8
