[Collins] Re: Advantages/disadvantages of an "L" tuner circuit?

Thu, 14 Nov 2002 12:58:16 -0700

The high pass "T" network can handle about the widest impedances I've ever 
seen; but on my own unit (for my S-Line or Johsnon Desk), I configure it 
sometimes for an "L" network which will handle almost as wide a range.  I 
suppose you could argue that the "T" is something like two back to back "L" 
networks.  Regardless, sometimes the configuration can become fairly High-Q 
and that's when I encounter some arcing. Summary: The L is a good, universal 
circuit, and I would give it a try. However, I have found a little more 
capability in my "T."  If you have the components, build the "T." - Richard,

All:

Just took a look at Ten-Tec's lineup. I was surprised that they show their 
tuner using an "L" configuration for matching. I was considering building a 
1KW tuner and if TenTec chooses an L designed, I figured "why not". Can 
anyone convince me either way? Oh, so that the topic is not off subject: 
it's for my Collins and Johnson rigs
