I this power/automatic operation category: Palstar HF-AUTO http://www.palstar.com/hf-auto.php RF Concepts/Alpha 4040 Automatic Tuner http://www.rfconcepts.com/PRODUCTS/New-Products/Alpha4040 E-Z Tuner - Jim Garland, W8ZR (2002 QST article and ARRL Handbooks) http://www.w8zr.net/eztuner/index.htm I made a suggestion to Steve at RF Concepts, a couple of years ago, when RF Concepts was planning a high-power HF automatic tuner. They needed to incorporate more uProcessor/controller power (since W8ZR Basic Stamp) in their planned offering, since the state-of-art has progressed since 2002. They did, using Linux kernel with the Beagleboard XM The Palstar and RF Concepts/Alpha offerings are INDOOR tuners. I have a preference to have the tuner outdoors at the antennas or feedpoints (like commercial broadcasters). == IF Wayne, N6NR is coming to Dayton - it would be nice to SEE one of the KAT500 prototypes == Greg, w9gb === previous message === Date: Fri, 24 Feb 2012 08:32:58 -0800 From: Wayne Burdick <n...@elecraft.com> Subject: Re: [Elecraft] high-power tuner To: Bill Hammond <wham...@aol.com> > We're just making sure performance is as good as possible.
