Throwback Thursday - vintage frequency voltmeter
Most radio hobbyist, have at least one 'boat anchor' lurking somewhere in their radio shack - and here at Teak Publishing, we have our own in the DX Cabin.
The above photo is of a Philco 128A Frequency Selective Voltmeter. And what is it for ? A Frequency Selective Voltmeter incorporates digital signal processing, based on design to provide high accuracy and stability. The unit is designed for level measurement of the selected frequencies, and also provides functionality of AC and DC voltage measurements. We picked this up at a Bob Grove Auction, and since then, has graced our shack.
