- Amplifier Experts: Perhaps you could lend me a bit of your experience? I acquired an old Alpha PA-77 this past weekend. This is the 1973 version of the 77: it uses a single 8877 and is a bit smaller

- Use your normal CW keyer. Place the paddle next to something so it sends a continuous stream of dots. Nice 50% duty cycle and adjustable rate. No RF involved. Worked for me when I did a similar measu

- Kevin, Couple of comments. Most importantly, the "wattmeter" in the AL-1200/1500/82 amps is NOT accurate. It is merely a voltmeter. SWR of any type (resistive or reactive) destroys any semblance of p
