Back to work on the K2 again.  This build session consisted winding several toroidal transformers and mounting them to the main RF board of the K2 radio.

The next two shots show the winding of the T6 toroidal transformer.  This transformer used a bi-filar winding technique where the red and green wires are twisted together before winding the coil.

Well it has been a long time since I have worked on the radio.  I thought that I had better start working on it so I could get it done.  Tonight I started slowly winding one more RF Choke.  The Choke is RFC11 and it is located on the bottom of the circuit board.
