Running a nominal 800 watts is 9dB (1½ S-units) above barefoot, and less than 3dB below the full US legal limit of 1500 watts-at about one-third the price. I read all the articles and reviews about it it’s well-designed, reliable, and a good dollar-per-watt value. It easily runs about 800 watts PEP, using a single 3-500ZG tube. I studied the situation for a few weeks, and finally settled on the Ameritron AL-80B amplifier. When the distant storms are running S9+10, you need to be at least +15 or 20 if you expect to be heard. We are currently in the low part of the 11-year sunspot cycle, and most of the HF activity is on 75 meters - and 75 is a very noisy band, especially in the summer. But recently I realized it was time to move up and as they say, run with big dogs. I ran barefoot (100 watts) for twenty years, with the convenience of an auto-tuner and push-button tuning. Frankly, I’ve always resented the idea of having to spend a bunch of money just to overcome someone else’s noise problem, but the fact is that most people don’t want to talk to you if they can’t hear you well. There comes a time in every hobby where we have to decide to either back out of it or get serious.
