[50mhz] 6m tuneable bandpass filter

[mweisbergs at juno.com]

I have a mil F-237/GRC-10 tuneable filter, made by Motorola, for sale. It
is a three-cavity filter, 50-ohms in & out and tunes 54 to 70.9MHz; by
resetting three internal caps it can be retuned to cover 49.5 to 60MHz.
This is a new unit, unused and unmodified, with a copy of a Dec 80 Ham
Radio article discussing its use on 6m & conversion to higher bands.
6"x11"x11", weighs 15.5 lbs net.  $35 + shipping from 07621
