[ICOM] ATU INFO PLEASE

[José F Ballester]

If you don't have a linear amp, the "tuners" inside Icom equipment 
should work well, at least the one inside my 756 Pro does.   However if 
you do have one, a linear that is (and you would hope it's pretty 
linear), you may want to look at those made by Ten-Tec,  Palstar or if 
you are good at correcting bad solder joints and loose connections you 
may want to venture (or maybe adventure) with MFJ.   I have equipment 
from all three and they will all work (cross your fingers and have a 
soldering gun and a good set of tools close to the the MFJ were you to 
choose that one;  open it and check it out closely before you try it).  
  I'm presently using a Ten-Tec 238 "tuner" and though not perfect it's 
pretty good.   Seems to work well with my no radials inefficient 
vertical.

Hope this helps.

73, Pepe WP3HW
