M.C. Jones MM-706 SWR/Wattmeter
 

I have one of these and if anyone out there can tell me the freq range
of this wattmeter/SWR meter. It has a coupler inside and appears to be
removable like the Bird. The meter scale goes to 400 watts.

MC Jones model MM-706 with N-connectors

It says MicroMatch on the meter face. Also has a phone jack on the
front panel, what would that be for?

Thanks for any help
