A solid-state kilowatt amp kit on the horizon?

pa1000

I’ve never understood why no manufacturer offers a 1000-watt amplifier kit (though Ameritron comes close with their amps needing a thorough look-over before power is applied). I think there is a market for such a kit and have thought that if one was offered, it would be based on a 3-500Z or some other tube. The…

An alternative to expensive solid-state amps?

A look at the prices of Elecraft’s KPA-500 ($2500) and various other solid-state amps from Tokyo Hy-Power (up to $7300), Expert (up to $8000) and even Ameritron will make one quickly realize why tube amps remain popular despite the inconvenience of needing to be tuned for each band QSY.

I wasn’t much more than a kid then, with mostly empty pockets. But today, my new-to-me QRP+ shares shack space right along with my K3, while most other…

QSK mod completed, tuner added

Shack updates were completed yesterday with the modification of my AL80B to allow QSK operation and with the arrival of a Palstar tuner. The results of the mod are great although its implementation has room for improvement. I wrote up a few “points of uncertainty” that I had while performing it in case others are similarly…
