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!

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!

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. 

See the incomparable Hy-Gain 3750 at your radio

SWIARC made money again on our McClelland Flea Market, mostly due to the cheap venue and generous donation of time by numerous club members – Flea Chairman Greg N0GR and all the others who helped greet, carry, and clean up.

Thinking Day on the Air

Girls Scouts Thinking Day on the Air.

February 18 was Girl Scouts of America Thinking Day on the Air. In this event scouts can earn their radio merit badge. Here Dudley has organized a station in Bellevue that you can see in photos attached to this story. Amateur radio gear is used to allow these young ladies to get on the air.   Location participants were volunteers and included Dudley KD0NMD, Albert KE0LOL, Ray N5SEZ, and Derek W0DBW.

 

A special thanks to all those that volunteered on location as well as the local hams that answered when we called out on the radio. Among those that answered our calls and spoke with the scouts locally were Tom WD0BFO, Bill KD0FJR, and Norm WA0JYD. There were others that responded as well and a special thanks to everyone involved.

 

Remember, Dudley has a net every Wednesday 8:00PM on the 147.39 Bellevue Repeater. Please stop in and say hello!  Click Here for More Info.

Co-Sponsored Club Picnic Report

We would like to thank Don W0AF for hosting a successful Saturday summer picnic. There were two HF stations operating during the picnic.   Hams were eating chicken and beef while the turkeys watched in relief. Although someone mentioned there were six wild turkeys before the picnic I seen only four when I arrived. Was that really chicken in the bucket?

The Southwest Iowa Amateur Radio Club (SWIARC) and the Heartland Hams joined together for a 2016 summer picnic with field radio operations. The event had been announced here and on the Heartland Hams web site. This was a social event with lots of good food including BBQ, potluck, and desert. It would have been in all practicality impossible to leave hungry.

2016-08-20DONBOBGARY

Two HF amateur radio stations were operational during the event. The timing was a fortuitous opportunity as the 20th was also a contest weekend.   Due to a very active North American QSO Party (NAQP) we were easily able to make many contacts from our portable HF operations.

Our primary station produced 63 contacts in 23 states and 3 DX contacts. The DX contacts were: Venezuela, Costa Rica, and the US Virgin Islands.

I think this guy flew in from Costa Rica after the QSO!

Rob reported, “Today’s SWIARC picnic was a huge success.  Burgers, hotdogs, fried chicken plus all the sides.  A good number of hams shown up.

Another attending ham said of the event, “These get-togethers are always a great way to get to know area hams better. I learn something new about a ham each time I attend one of these.

Bill KD0FJR used his portable VHF/UHF station as a call-in before and during the event.  We got to see his miracle good luck radio, the little Yaesu that could.

Someone asked, “Where the heck is ZQG?

Any more updates and comments will be posted here as time permits!  Submit your own pictures!
