Re: [IRCA] All Hail the SRF-59!

["Gil Stacy" <gilstacy@xxxxxxxxx>]

Kevin,
The top of the case has a recessed dimple which encircles and presses down
on the center hub of the thumbwheel.     An effort has been made by Sony to
lubricate with grease this area of contact.  Perhaps a little trimming here
would help.  Costs have been cut in the tuning department as Karl Zuk has
commented it appears to be a nylock tie strap with teeth in it acting as a
toothed "rack" to move the indicator bar.  The thumbwheel is geared to mesh
with the rack.
I made a simple ferrite rod "loop" antenna from a Bytemark 4" long, .5" od
mix 61 ferrite bar with close wound 165/46 litz wire over the center for
about 2".  It's connected to a small bcb Jackson Bros. air variable.  It is
enclosed in a  5"x2"x2.5" plastic Radio Shack project box  It will boost an
inaudible signal comfortably audible.  I sit my "Big Wheel" 59 and the
ferrite loopstick on a plastic turnable from Bed Bath and Beyond.  It's a
fun set up.  I've heard several TA hets on it, but no cigar.  It's been
weeks since I've heard audio on a TA on my Drake R8B here near the GA coast.
