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.

  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
