Hi Dave - saw your comments on the Z-match antenna tuner - after reading
some of Bill Orr's columns in CQ recently the Z-match looked
interesting. I was wondering where you got your info to build one? Also
I see there is an outfit (I think in Southern US) selling a commercial
version of the Z-match - first I've seen. Have you heard anyone using
it? I always keep saying to myself that there MUST be some loss through
my MFJ tuner when I use it's internal 4:1 balun at QRP work and either an
old Johnsom Viking Matchbox or the Z-match would be a better way to go
considering they are more "closely coupled" to the 450 ohm balanced feedline.

It seems your experiments so far with the Z-match doesn't prove that out
yet. Anyway I'd like to keep posted on your progress. Any efficiency
improvement in the antenna system will help out my 6 element balanced
feedline 40 meter yagi... ;-) when using it QRP.

72 and thanks Bob VO1DRB/WA6ERB
