We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
AM MONITORS
For AM Broadcasting the RCA line includes the 311-AB Frequency Monitor shown above and the 66-D Modulation Monitor — both FCC approved types — and the relatively new Type 300-C Phase Monitor, the finest instrument yet designed for adjustment and monitoring of directional antenna arrays.
FM MONITORS
For FM Broadcasting the RCA line before the war included the Type 322-A Modulation Monitor shown above and the Type 336-A Frequency Monitoring Equipment — units which were specifically approved by the FCC for FM station use. Planned for production after the war is a combined modulation and frequency monitor of improved design.
FOR ALL KINDS OF BROADCASTING
RCA manufactures a complete line of broadcast equipment — including not only such operating units as microphones, amplifiers and transmitters, but also such necessary accessories as modulation, frequency and phase monitors; audio measuring equipment; and field intensity meters.
RCA Test and Measuring Equipment units meet all the needs of FM, Television and ShortWave Broadcasting as well as AM Broadcasting.
The proof of these RCA equipments is in their widespread use. Almost every broadcast station has one or more; nearly all the networks have several. Other manufacturers use them. The RCA companies — NBC, RCA Communications, Radiomarine Corporation and RCA Laboratories — use them in large numbers.
