SWR Meter - Minimatch
The 'Minimatch' differs from the 'Monimatch' with respect to its transmission line (RG-58/U
used instead of stripline-on-PCB).
Two lengths of hook-up wire, running in parallel inside the braid, are the sensing lines.
A tuning indicator (salvaged from an old Philips transistor radio) is used as the indicator, along with a 47KΩ potentiometer for sensitivity adjustment.

This SWR Meter is identical to the 'Monimatch', published in ARRL's 'Understanding
Amateur Radio'.
It was not difficult to follow the 'stripline-on-PCB' design.
A 100µA meter reads 'forward' or 'reverse', based on the toggle switch position.
A 47KΩ potentiometer is used for sensitivity adjustment.
