vfo A & B set up

Thank you to W8ZN, K1EP, VE3KI, and K3WC ( phone call ) for your help. My
K-3 is now set up for 20 & 6 just the way I wanted it to be. Fortunately
Elecraft has many great customers who unselfishly give some of their time to
help others. Everyone have a great day, and thanks again!! John ,K8DHA

K3 Modification

For Information:

After doing all the modification for 3 older K3's SN <300, all 3 did not have output anymore and showed a err txg.

Doing these Mods on different days in the last montht the mistake
didnt show up untill recently when the others explained they have the
same trouble as I had
Had a lot of emailing with Gary from Elecraft.

He was very helpfull and we spent houres looking into the trouble.
Tnx Gary for your great support

Finally I found out the Capacitor C222 which was replaced by one who was supplied marked "103" didn work.

Replacing this capacitor with a normal 100nF Capacitor got all 3 K3's back to life.

So if anybody doing this mod "CW Risetime" be carefull what capacitor you take.

Re: K3 Modification

Tom,

100 nF is 0.1 uF, which should be marked "104". If you used capacitors
marked "103", the value was 0.01 uF or 10 nF.

Thanks for the 'heads up'.

73,
Don W3FPR
