  • Annotazioni
  • Very little information is available on this company other than it had manufactured a few crystal receivers and a few components.  In one of their ads, a "Key to the Air" permanent cartridge detector is listed guarantying clear and loud signals, especially during the summer,  ...one is on this radio.  The company also manufactured "Key to the Air" fixed mica foil capacitors and claimed they were very accurate and the design reduced noise which was associated with other designs.   Stephen F. Stafford was a principle,  and is credited with a patent for an Indoor Helix Cage Antenna.  No other patent was found under his name or the company name.
     
    This radio the "Key to the Air" was also described as a Neuflex receiver in their ad.  On local strong stations they suggested that the receiver could be used, as a straight crystal receiver,  without the tube or batteries and that the earphone be plugged into the separate jacks provided.  The claim was also made that on local stations using the full radio, a loud speaker would produce audible sound.
