[Hammarlund] Yaesu Rotor Problem

[Mark Huss]

The trick here, Glen, is to wire twisted pairs in parallel. This reduces 
the capacitance and inductance, as well as letting it handle more 
current. The resulting improvement in rise time and bandwidth allows you 
to turn your rotor at up to 40,000 RPM. Sort of like Litz wire on 
Steroids. Once you have done that, sell it on EBay for $50 a foot, 
minimum quantity 100 feet. Don't forget the buzz words like 'Aged', 
'Classic', 'Rare', 'Tested for extreme environmental conditions', and 
that all important 'You can trust me. I'm not like the Others.'
