DRISCO RADIOMETER Type DR-101 In this article we present an instrument entirely new in the Radio field. Taking the place of the conventional variometer and variocoupler the RADIOMETER has the ability of increasing broadcasting reception to a remarkable degree. Aside from being an innovation in Radio, it has many unique patented features which may be found on no other instrument. The windings of the primary are of No. 16 enameled wire and the taps are attached to brass eyelets which are securely fastened to the tube. This does away completely with the old-time scraping of the cotton covered wire and absolutely prevents the windings from becoming crossed or loosened. Another feature is the absence of the so-called "pig tails" or straggle wires, as every lead terminates at a Fahnestock clip, making all connections perfect. A dial, calibrated from 1 to 100 around the entire edge is furnished with the RADIOMETER, and one complete turn of the dial will vary the inductance from full to zero.
