[Elecraft] KX-1 has been born, TWICE

[B.G.]

Hi all,

I haven't seen this type of post before, so smile & enjoy.  I just completed my KX-1, S/N  2074,  with the ATU and the 30-80 option.  
My unit was 'born' twice, because a while ago, I tested the original 20-40 unit  then the ATU.  Worked perfectly.  QSL's rcvd, both bands.

I completed the 30-80 boards the other day, and it again works perfectly.  30-80 had WWV & readable signals right from the power up.  I don't know if my unit has special parts (sent by Wayne) or not   ;)      RX current draw is  < 40 Ma. on 20-40,  < 41 Ma. on 30 and < 61 Ma. on 80, using 13.6 volts.

Now for final RX alignment peaking and final adjustment for TX output.  Then rigging up my gel cell power supply and I'll be all set.

My only nit-pick refers to the (routing) of the green toroid wire L2-1 from the LPF1 module to the KX-1 BOARD.  The errata sheet gives the 100% correct procedure, but practicality told me it won't work.  After a quick call to Scott & a call from Don W.,  a procedure was suggested which I recommend for all builders.  Maybe Don can post on the reflector.  It involves using a 3/16" piece of the Green insulation.  WORKS PERFECTLY.  Thanks guys.

Question, I've talked to Don W, and others, but I'd personally appreciate comments on E mail for suggestions on the "best" effective single 'cheap' portable antenna which will load WELL on 80 meters ..... and on the other 3 bands too.  I'm looking for a permanent antenna at home and a smaller one for portable.

Great kit, much fun building it and now to get my code speed up to 5 wpm before FD.......
