Some paint loss on case

A square-connector (MVP and MASTR II) microphone plugs into the left side of the test set, and the older round connector microphone plugs into the right side, as does the test cable to the radio. If you will be doing a lot of radio tuneup work it may prove valuable to hunt down a round mic connector and connect a foot switch with a 5 to 6 foot cable across the PTT and ground pins. You can have a MASTR II mic plugged into the square connector and the foot switch can be used to control the PTT leaving both hands free to twist the tuning tool and work the oscilloscope.
