<\/a><\/figure><\/div>\n\n\n\nThe Hammarlund SP-100X Super-Pro radio is an all-wave radio center receiver, one of the varieties of the famous Hammarlund Super-Pro series. <\/strong><\/h2>\n\n\n\n The new “100” Super-Pro series was introduced in January 1937. The frequency range is 0.54 \u2026 20 MHz. Types of work – TLG and AM. Quartz filter. Desktop version in a metal case. Hammarlund Film Company (USA). The SP-100 series has been in production for about three years. The total number of SP-100 Super-Pros produced was about 1200 receivers.<\/p>\n\n\n\n

<\/a><\/figure><\/div>\n\n\n\n The case for the early Super-Pro and SP-100 is really nothing more than a dust shield that is secured with eight thumb nuts in the front and three thumb screws in the back. The back of the dust cover has a metal ID tag with printable receiver type and serial number, but in most cases it bears some kind of factory identification code – usually two letters. A 19 “rack mount model was available with the Crystal Filter option enabled. The front panel on early pre-WWII Super-Pro receivers is made of 0.190-inch aluminum. First, the black fold was processed and then the engraving was engraved. This resulted in the nomenclature looking bright silver.<\/p>\n\n\n\n

If a crystal filter was added to any version, the suffix “X” was added.<\/p>\n\n\n\n
