Photos are in a zip file at http://www.gatesgarth.com/radio.zip
They also show the antenna, a vertical feeding the corner of my HF
horizontal quad loop. The corner of the loop ,and the vertical is
supported by a long stainless steel cable to a fibreglass scaffolding
pole at the top of my crank up mast. Not sure if I should replace the
wire with none conductive rope, the two insulators are at the ends of a
short length of Dacron rope, then that is tied to the stainless cable
to the mast top.
The green bin houses the loading coil with variometer within it. The
white plastic box on top of the lid of the loading coil drum houses
the tapped matching transformer. the RG-213 goes upstairs into my
shack where it is fed from the LPF after the combiner. The combiner is
to W1VD spec, but instead of a three stacked toroid output transformer
I have made an auto transformer on a bobbin core, which runs a lot
cooler and seems more efficient.

The LPF is after the combiner.
