John W2XS, I have been wondering about a balanced L network auto tuner for some time now. No one is making one that I know of at this time. Like you, I thought it would be great for the Elecraft guys to produce a kit for it.
And Don K7FJ, I would be very interested in following your progress in building one of these as you described in your post. Here's my wish list. 1) Balanced output using a balanced L network with 2 set s of inductors and one set of capacitors. 2) Current balun at input. 3) Programmable and switchable to be able to use unbalanced line as well by: switching the balun out of line, and bypassing one set of inductors to effectively be the same tuning circuit as the presently available L network autotuner. 4) At least 2 antenna inputs (even better 3) each separately programmable and switchable for balanced or unbalanced as stated above. 5) 160m - 10m capability. 6) Bypass function. 7) 150w power handling minimum. 8) Maybe an option kit to add an analog meter if the user wants one. 9) Same algorithm as KAT100, where it searches for the best match, not just an "acceptable" one. 10) Function to auto-retune when a certain (user selectable maybe) SWR threshold is exceeded. 11) Integration with the K2 "TUNE" and "ANT 1/2" functions as the KAT100 does 12) Selectable Ability to use stand-alone with other non-Elecraft rigs 13) A kit So Wayne, Eric, what do you think? Another idea might be to sell production rights to manufacture an assembled version. I bet lots of people who maybe don't like kits would be interested in an assembled one. This thing has the potential to be marketable to a very much larger customer base than elecraft's current product offerings. Of course I'd buy the kit, and use it faithfully with my K2 (s/n 4429) which is very close to completion by the way. -Ben KB1AHR _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
