Just as a bit of anecdotal data, I am feeding a 20m dipole with 1200 watts
through 600-ohm open line on 40 through 10 meters. The SWR on 40 meters
approaches 100:1 (the line is short, but I am still eating about 2.2 dB loss).
Anyway, this presents a very difficult problem for most tuners -- and

There seems to be some disappointment that a relatively compact wide-range
auto-tuner at legal limit CCS (or even ICAS) is not included. I don’t consider
this a negative.

1. A legal limit "LOW LOSS" CCS tuner using the build methods of most typical
ham auto-tuners would be large and heavy wit
Hi Wayne/Eric and all,
Congratulations; it looks you have done what everybody wanted. Do you have
any data on IMD at the 1500W level? I have been pleading with you in the
past to take the lead in improving the miserable record of solid state PA
stages. Is it happening?

Without modeling it, I would guess that it will actually narrow the matched BW
and it makes it a single band antenna at the same time.
My Drake L4-B would drive anything. When I decided I needed a new challenge
(9BDXCC) I wanted to get on 160. Of course the Drake didn't cover 160 and my

I have to keep physically restraining myself from placing an order
just for the pleasure of owning one! It's *just* *so* *Elecraft*! :).

Well done! Simply superb effort to overcome multiple and significant
obstacles on many fronts.
Please, do place me on the list of folks keenly interested in knowing
when one might place an order/pre-order. :-)
