All,

Have this nifty little box here nomenclated as above. Label sez it's a "NETWORK, IMPEDANCE MATCHING."  Appears to be an antenna tuner, coax input to end-fed wire.  Chart on the top shows "Bandswitch" settings over a range of 2 - 6 MHz for HORIZ WIRE, INVERTED L and SLANT WIRE and also settings for 30 and 15 ft. monopoles over a range of 6 - 30 MHz.  Haven't completely doped out the innerds yet but has a couple of internal coils (tapped)and three variable caps. Low power judging from the size of the components. Also has and a bunch of internal resistors, a tune switch and an indicator light in what looks something like a QRP version of the ME-162 box.

Anyone know where, how and with what this thing was used?  Manual/schematic?
