[TenTec] Ten-Tec 228 vs 229 Ant Tuner

[Greg S]

You mean 229 and 238, I am guessing. Latest 2 or 3 Iterations of the 238 used a turns counter for the inductor. Last one (C) has cross needle meter. Ceramic capacitor values changed slightly from the 229. The 4229 was a kit version.... Early. Voltage baluns. Prolly stir up some angst, but I wouldn't use the balun without reworking it. Just me. Not sure of transformation value.... Others will know. Greg, KC8HXO

 Can anyone enlighten me (and others) as to
 differences between the later 229 models and 228 models. 
 Presumably some technical improvements
 were made?
 
 Re the installed  balun : is it a
 current or voltage balun, and is it 1:1 or 4:1 ?
 
 Thanks.
