I have a new TX-500 and I was just doing some power output measurements.
My power supply is 12.6 volts dc. I am using a good 50 ohm non inductive dummy load and an Elecraft W1 wattmeter that is pretty accurate.
Here is what my radio is putting out in CW mode.
BAND. ? ? ? ? ? 100%. ? ? ? ?50%. ? ? ? ? ?30%
80m. ? ? ? ? ? ? ? ?15w. ? ? ? ? ? 8w. ? ? ? ? ? ?5w
40m. ? ? ? ? ? ? ? ?15w. ? ? ? ? ?10w. ? ? ? ? ? 5w
30m. ? ? ? ? ? ? ? ?14w. ? ? ? ? ? 10w. ? ? ? ? ?5w
20m. ? ? ? ? ? ? ? ?15w. ? ? ? ? ? 10w. ? ? ? ? ?5w
15m. ? ? ? ? ? ? ? ?15w. ? ? ? ? ? 10w ? ? ? ? ? 6w
10m. ? ? ? ? ? ? ? ?12w. ? ? ? ? ? ? 8w. ? ? ? ? ?5w
This is a lot higher than stated power outputs. I don¡¯t have a problem with this as long as it is normal for this radio.
Has anyone else done any testing of their power output levels?
