[GreenKeys] MicroMatch SWR/Watt meter

[Gerald]

Hi Folks
Trying to find some information on a M.C. Jones Electronics MicroMatch model 
# 707N SWR meter. I have photos at 
http://www.projectgm.com/html/micromatch_swr.html . In the photos you can 
see on the front of the unit the switch on the left has FOR, BACK, CAL, 
VSWR, the switch on the right is for calibration. There is also a jack in 
the front and I assume it is not for head phones. Can anyone give me any 
information about this unit or should I just set it on the shelf for a 
conversation piece.

Thanks
Gerald
