Re: AL80-B tuned input
Here's the secret for 30m. 20m and 30m share the same slug and they are far apart in frequency. The advice I got from Ameritron is that you can tune for 20m OR tune for 30m. You can't have both. Make

AL80-B tuned input
The 2 prior posts are a perfect segue into my question. My input SWR on 30 is over 3 to 1 and 12 meters is about 2 to 1. The rest seem ok. I have searched high and low for instructions on the proper

AL-80B fan
Hi all, I'm going to help a friend replace the fan in his AL-80B amp. Is this an hour job or do I need to count on a half day or so? Thanks, Bob W4JFA

Re: Tuned input
I have the AT100 AMP board with the special PIC. I believe the chip is common but I don't think I know anyone that can copy them. 73, Alek VK6APK

Re: Tuned input
Wasn't there a 7 call ham that made such a board? Think he also made high voltage boards.

Re: Tuned input
I suppose the answer to that would be to disconnect power to the tuner after it's done its job.... Or rewire it so it only tunes when power is applied, then you remove power to keep it from

Re: Tuned input
Hi Tuner-Seeker W7WRX! I believe that LDG makes a board-size tuner just for amp builders. 7 Band, 9 Band, I'm not sure. But they advertise in QST. They've been doing that for years. Happy New Year

What negative voltage ranges should a find in this amplifier¡¯s ALC circuitry? I know it depends on the setting of the pot. Just curious about what variation I should see. Richard WB5NEN
