Note
The PM-2 was first announced in Electronics World, June, 1959, and is essentially a restyled version of the PM-1.
It features a magnetic base to hold it down and has a working range from 100 kHz to 250 MHz with 0.3 volts RMS sensitivity. The meter movement is 200 µA full scale.
It was sold for 15 years and originally cost $12.95. Toward the end of its production life, it seemed increasingly anachronistic. It was odd to see it being sold side-by-side with the SB-104.
Its two-tone green design and sloping cabinet matches the HD-20 crystal calibrator. Early units used metal knobs while later ones used a small gray plastic knob of the style used on the PM-1.
