All,
I was noticing tonight that ive got a weird output power with my 891. If got my power meter (Yaesu YS-60) connected to the antenna side of the system so I can see what the tuner is seeing SWR rise and so I can see reflected power from the antenna and output power out of the tuner. It was kinda weird. I was doing PSK31 and had the radio set to 30watts output. The power output out of the radio according to the power meter was right about 30 watts with peaks of 50 watts. On the antenna side how ever its showing about 50 watts output with peaks of 75 watts and a reflected power of about 30-50 watts with an SWR of 2-2.5:1 on the antenna side. The radios SWR meter is showing about a 1.5:1 going into the tuner which should be correct. Whats going on here? Why is there so much power amplification going on inside the tuner? My antenna is cut right for 40m 33ft each side and is up about 20ft in an inverted vee. Im worried about the radio and cooking the insides. This was tested using PSK31 so I’m not sure if that’s a factor of it.
Thanks
