[Boatanchors] Unique Wire Tuner Problem

[D C _Mac_ Macdonald]

The tuner I just recently bought on eBay is apparently the next to latest version with two input SO-239 connectors and a plug to choose either capacitor or inductor input L networks.  I think the final version added some banana jacks to include additional capacitors to extend the range.  Another boatanchors list member offered up a used Groth counter for postage charges.  I have already paid him and he will send it my way tomorrow morning, depending upon "wifely" tasks!  HAR!  If he okays it, I will identify my benefactor here.

The Unique Wire Tuners show up at hamfests sometimes and are a pretty
good bargain for parts.  They usually go for around $100 but for that
you get a couple of nice shaft insulated couplers, bushings, an
insulated ceramic feedthrough, The Groth turns counter, aluminum
cabinet and an EFJ air variable cap and EFJ roller inductor.  The
inductor is a plated wire inductor on a ceramic form rated for 5 amps
that is around 22 µH and often goes for $75 on eBay on its own.   The
air variable is a smaller common cap used by Johnson and Hallicrafters
for an output loading cap in their 100 watt rigs.   You can add some
fixed value doorknobs, rewire the tuner and have an okay L network
tuner for an inverted L or some other vertical.  It will handle a
BC610, Viking 500 and lower power rigs FB.
