[Boatanchors] Johnson Kilowatt Matchbox ?

[David C. Hallam]

I don't have a KW match box, but my 275W match box has a separate module 
that contains the RF bridge, Johnson PN 250-24.  It has leads that plug 
into the match box.  The meter is mounted on the match box itself.  The 
RF bridge was inserted in a coax line between the transmitter and the 
match box.

I know that Johnson also made a meter, 1 mA movement, mounted in a small 
case that could be used with the RF bridge without the match box.
