Among the vintage classics at the Lincoln Hamfest / State Convention was this beautiful Hy-Gain 3750 HF transceiver acquired by Greg N0GR. Originally in the U.S. market this radio was sold as the National RJX-1011D and some identical units were even labeled Panasonic! See pictures from the Lincoln Hamfest and more on this mysterious boat anchor! Who went to the Lincoln Hamfest?

Capable of operating on the pre-WARC bands in SSB and CW modes only. The Hy-Gain logo is displayed on an anodized aluminum front panel, a company formerly located in Lincoln Nebraska. This Hy-Gain is actually a National RJX-1011D.

A former employee of Hy-Gain said the Achilles is basically a fuse buried deep within the main transformer that, when blown, is not easily replaced. It was advertised as 200w however actually put out 100w transmit and an input power of 200w. The finals are a pair of S2002 (6kD6) beam power pentode tubes.

The 3750 includes a digital frequency display that can be calibrated against the WWW 10MHz signal, voice operated relay (VOX) operation, break-in keying, special interference suppression circuits, and an automatic gain control (AGC) with selectable time constants.

Excerpt from a 1976 73′ Magazine Advertisement:

   There is no substitute for qualify, performance, 
   or the satisfaction of owning the very best. 

   Hence, the incomparable Hy-Gain 3750 Amateur 
   transceiver. The 3750 covers all amateur bands 
   1.8-30 MHz (160-10 meters). It utilizes advanced 
   Phase-Lock- Loop circuitry with dual gate MOS 
   FETs at all critical RF amplifier and mixer stages. 
   There's a rotating dial for easy band-scanning and an 
   electronic frequency counter with digital readout 
   and a memory display that remembers frequencies at 
   the Rip of a switch. And that's just the beginning. 

   Matching speaker unit (3854) and complete 
   external VFO (3855) also available.
