Toroid winding completed

Toroids on the right are transformers, each has two windings.

Large toroid on the bottom is for the VFO.

For me, having a good magnifier was key to good winding and properly
adjusting the spacing of windings, especially on the VFO toroid, which
has 60 turns of #28 enamel wire. I used a small plastic probe to make
spacing adjustments.

Next step: installation of toroids.

After that: installation of the unit's controls, connectors and panels.

Then: final assembly, tuning & testing.
