I just received a Yaesu 450D and I have a problem. I'm using it with a G5RV Jr., strung across the top of a six foot wooden fence. I can set the power output to 100 watts and set the Dim Meter on PO for power output. I pushed the 'Tune' button so the ANT diagram is blinking, meaning the internal tuner should be on and working. When I key down, the Power Output meter doesn't even go to 1 on the meter and my power supply shows I'm barely using any amps. I'm guessing this means that Im' not transmitting for some reason. I hooked the antenna up to an SWR meter and it barely moves the dials, which I'm assuming means I've essentially got no output. I know the internal tuner on the 450D will only work for SWRs less then 3, but how do I know that's the problem? My question is, has the radio shut down transmit for protection for some reason (High SWR), or do I have a problem with transmit on my new radio? Any way to tell?
