K2: RFC11

[Linden, Mike (BRC-Hes)]

  I'm looking for input on the winding and installation of toroid RFC11
which mounts underneath the K2's RF board. Assuming I wind RFC11 such that
85% of the toroid is used, I don't see how it can "easily" be secured by the
leads given the location of the lead holes. How has this worked out for
folks who have built their K2s?

  Thanks, Michael  N9BDF
  K2 SN #4137

and the "Amateur Radio Spectrum Protection Act" (HR 713 & S. 537) are in

Hi

I use a small square of double stick foam tape for RFC11 and T2 in the transmitter. This tape is about 1/16 inch thick so it works on T2 to mount it up above the board a little to improve the output on 10 meters.

Michael,

I wound RFC11 exactly as directed by the instruction manual; and I had
no problem.  I even went downstairs and took the bottom cover off my K2
just to doublecheck.  I am in the phase of aligning the filters befoere
starting Assebly Part III of the RF board.  If you're using the proper
holes it shouldn't be a problem.
