Marinus,
Thanks for the reference to the S-Match. That's a neat development from my
beloved, link-coupled, parallel-tuned circuit tuner. I filed it for future
reference.

Geoff
In your drive for equipment on the cheap I like to draw your attention to the
S-Match as promoted by PA0FRI:
http://www.xs4all.nl/~pa0fri/ATU/Smatch/smatcheng.htm<http://www.xs4all.nl/~pa0fri/ATU/Smatch/smatcheng.htm>
It uses only three components, tunes very easily and can handle both balanced
as unbalanced antennas. Unfortunately you may have to build a different version
for 160m than for 10m because minimum capacitance values do have an impact.
It should be the ideal beginner's project, in particular if I see prices
asked for "commercial" antenna tuners and which often contribute a considerable
expense towards establishing a station.
By the way - even with the older tentec gear like the Omni-C one does not
need a SWR meter since that is already built in to the rig. (And "standalone"
SWR meter's prices are through the roof for such a simple piece of equipment)
Enjoy, 73, Marinus, ZL2ML
