[Heathkit] Sixer mods

[WB6BLV]

For those not familiar with the Heath lunchboxes, there was a nifty mod out
by CQ which converted the receiver to a superhet with a super-regen
detector.  That greatly increased the sensitivity and narrowed the passband.
A single nuvistor was often used for the mod but in checking just now I
found at one circuit used a pair of 6CW4s as local osc and rf amp, with the
original circuitry doing the mixing and detecting.  I have a Twoer with this
mod and it is really quite amazing.  I do have a copy of the mod as done on
the Twoer a la CQ mag.
