[Elecraft] K2 - Need Some Help!

[Andrew Moore]

I remember having the very same brain failure at that point in the
construction.  It can be very confusing.

If you check the schematics in Appendix B of the K2 manual, on the RF board
page showing the antenna connector, you can see the 4.7 pF cap connected at
pins 1 and 3, which lets the signal bypass the 60 m module (assuming it's
not installed) -- not across adjacent pins such as 1,2 or 2,3.

This really should be clearer in the manual.

After building my K2 and connecting the cap across the wrong pins, the
receiver seemed deaf, and I ended up doing signal tracing until I found out
there was no path between the antenna and the rest of the receiver.  It took
help from the Elecraft list to realize this.  Guess it's my turn!
