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?

It was 36 case screws shy and weighed around 65lbs, capable of operating on the pre-WARC bands in SSB and CW modes only.  It proudly displayed the Hy-Gain logo on an anodized aluminum front panel, a company formerly located in Lincoln Nebraska.  This Hy-Gain is actually a National RJX-1011D and went for a fraction of its online value.  The cosmetic condition was excellent, however, no report on the operational status. Great grab Greg!

A former employee of Hy-Gain, Evan, had several tables and although he was not the seller of the Hy-Gain rig, he knew a great deal about that model.  He 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.

Evan had a beautiful Collins 51J4 receiver that he sold for an excellent bargain.  Between the Hy-Gain and Collins I was kicking myself for not pulling the purchasing trigger before it was too late.

What did you (any reader) come home with from the Lincoln Hamfest?  Send us your pictures and we will post em here!
