[Elecraft] Re: Is info on "revised" K1 details coming soon ???

[Wayne Burdick]

Hi Mike,

Sorry for the delay on this. We're planning to more detailed info (and
the new manual) on the web site, but we're a little busy with other
projects at the moment, not to mention taxes.

Nearly all of the chages were the subject of earlier application
notes--we just incorporated some them into the PCB and manual to make
construction and alignment easier. In addition to the app note mods,
we've made it easier to do TX offset. The way we did this is to put a
miniature slide switch on the bottom of the RF board, so if your TX
offset is already aligned, you might not want to go to the trouble.
Similarly, we added a 3-pin header/jumper in the vicinity of R36, so if
you have the KAT1 installed, you don't have to solder/de-solder this
resistor to do alignment of new Filter boards. If you do this a lot
(most builders don't), rather than use a 3-pin header, you might want to
wire a slide switch in here.
