[Elecraft] K1 TX alignment problems

Tue Aug 13 10:16:01 2002

Hi

Set the output to 2 watts like the manual describes then tune for max out=
 and go out of tune and then back into tune. This allows the ALC circuit =
to readjust to your tweaking. You must do the alignment in the order list=
ed in the manual because the circuits interact. The filters are very shar=
p and all of the adjustment for each band interact. You may have to go ov=
er the adjustment several times to get it peaked up. If you can not get t=
he upper 2 bands to adjust you may have a problem on the filter board. Lo=
ok for a bad solder joint on one of the toroids or a wrong part value in =
the filters

everything is wishy-washy.

i go to 10 MHz band, put in tune mode, and adjust to 2.0 watts or the max=

get out of TUNE and go to 18MHz. I cant adjust to 2.0 watts. Highest it w=

go is .7-.8 watts. Ditto with the 14 MHz band. For practicality i change =
OUT =20
power to 5 and enter tune in each band. When i enter TUNE i get 2.0 watts=
