Well my Al-811 arrived today. I hooked it up to my Kenwood TS-590s. Everything is hooked up correctly - radio to amp then to the tuner and then to antenna. I am using a Kenwood alc/relay cable - ALC is unhooked as per the Ameritron instructions. So I turn off my internal tuner, output power of radio set to (20-60 watts - tried different power levels), Menu 53 set to 2 and tried 3. Tuner is an MFJ989D. So when radio is in "standby" I can tune up the radio to a 1:1 swr and receeive just fine. Power output is indicated on the meter and is real close to what the radio is set at. Now, when I want to use the amp, I check the chart that is in the instructions for load and plate settings and set accordingly. My volt meter on the amp shows 1700 volts. Grid shows 0. When I switch to "operate" mode, while in cw mode (as per instructions), key the radio - the red TX light lights up and the Grid Meter goes from 0 to 20ma. My swr/power meter show no movement and the swr meter in my radio is high. Adjust the load/plate or radio power has no bearing on the amp. I go back to "stand by" and have full power output. Any idea what I am missing here? Oh and radio is set to the appropriate antenna port. Thanks for any help!
