Sounds good Mike. That's basically how I tune the AL-80B, although the
3-500Z tube can take a bit more both in drive and key down time.
I think in his other tuning method, he is using a pulser or other device
giving a very low duty cycle compared to solid CW key down.
I guess there are many methods and tricks, but as long as you keep the
smoke inside and keep the RF going out, all will be well.
73, good luck, Steve KW3A
