[Johnson] Slide rule - was: Johnson T-R Switch Receiver muting

[Bill Cromwell]

Hi,

I still have three slide rules around here somewhere. Once upon a time
(1981 or 1982) at Field Day somebody from one of the phone stations came
around looking to borrow a calculator as theirs had dead batteries. I
took my slide rule to their station for some antenna work. Of course, I
also had to use it for them <evil grin>. They were amazed their antenna
worked FB on the first cut. One nice feature of slide rules - the
batteries never run down!

To be honest - a slide rule was not really required for those
calculations just as a calculator would have been gross overkill.
