Hi

Did you remember to install the little one turn loop on T1 and disconnect

Subject: [Elecraft] Help with KAT1

Of all the kits to have trouble with...  The KAT1 is pretty simple but it's
got me stumped.  On page 9, I go through the steps to calibrate the SWR
bridge but the voltage at TP1 varies only slightly between 1.6 and 2 volts.
Power out under any circumstances with the Kat1 installed is 0.  Can receive
only faint signals.  With KAT1 out, the K1/4 works perfectly.  If I clip a
test lead to the center pin of the antenna coax and then touch P2 pins 9-10
signal levels come way up.  If I touch K4 pin 3 signals come way up.  Same
for K1-K3.  I've examined ever part with a magnifying glass looking for
trouble. Everything looks perfect.  I pulled out T1, carefully rewound it
with fresh wire and reinstalled - no change.  I know I'm missing something
pretty basic.  I just don't know what.  Appreciate any assistance very much.
