Hi Gang: I have a multi-turn counter knob that is very similar to the one used on the R-390A "spy" version as used by the NSA, ASA, CIA, etc. I am asking $30.00 postage for it. If interested please reply by e-mail. 73, Michael, W1RC michael*at*w1rc*dot*net PS: See you at NEAR-Fest V May 1st and 2nd. www.near-fest.com
