- Lynn Put a resistor from plate ground to simulate the load and look into the output with an MFJ 259. Tune for a match. Works like a charm. George W6TC I am starting to forget all I know! Component

- I'd echo W6TC's good advice - a resistor of the same value as your calculated resonant load impedance or that off the data sheet for the drive and ht you're using. Just make sure it's a non-inductiv

- One way is to hook up like the other guys are saying, but also put a directional coupler in series with the tracking generator. Any reflected power will show up in the coupled port, where you attach

- I have a question about the other end of an amp. I don't own a monitor, but could an MFJ-259 be used to tweak the bandswitched input tuning coils of an AL-811 by sweeping the input (while keeping the

- One thing to keep in mind - the input impedance of a GG amplifier is strongly influenced by the output tuning of the amplifier and the output levels of the amplifier. Hence the suggestion that checki

- All great advice! Hell, I wish there'd been an Amps Reflector when I built my first multiband HF amp. In fact, I wish there'd been an internet! :-) cheers Dave G0OIL One thing to keep in mind -
