The ACOM 1000 HF Linear Amplifier is one of the world's best value in an amateur HF amplifier. The ACOM 1000 gives you a 1000 W output on ham radio bands from 160 to 6 meters.

This week, we’re looking at a few practical builds and some useful tools for the shack. There’s a good write-up on constructing a 70cm collinear, something that often comes up for local repeaters or even satellite work, offering a decent gain figure from common materials. For those interested in portable HF, we have a couple of magnetic loop designs; one covers 40m-17m, emphasizing portability, while another focuses on broadband reception, which can be quite handy for monitoring. We also found a CW contest simulator, Web Morse Runner, which lets you dial in bandwidth and speed, a good way to keep those skills sharp without needing to be on the air. Finally, a new supplier, Chatt Radio, has popped up, worth a look for parts and gear.
