Okay I have a G5RV antenna I am tuning 80 meters with an MFJ 969 Delux manual tuner since the Yaesu ft 450 d internal tuner wont touch the SWR . Periodically I need to turn off the radio in order for the tuner to tune. I get no forward power or reflected power on the meter. I set the inductance as well as the Antenna and the transmitter dial to the recorded values I have always used and the needles don't move. Once I cycle the radio off and on twice it works and I get a 1-1 match. Any ideas what could cause this?
