New Arrival: Swan 700CX SS-16B Transceiver


Recognizing Radio Amateurs 0 Comments 05/31/2018 (This is a Level 0 News item)

This 1974 powerhouse features two 8950 PA tubes and a 16-pole filter.

This clean and highly desirable Swan was obtained from a Schulman Auction.  It was actually packed well by a local Missouri UPS store, with lots of bubble wrapping.  Aside from a slipping inner VFO action, and having to turn the unit off/on from a power strip, it loaded right up on the 20M Vintage Sideband Net, receiving good reports from stations in Nebraska, Texas and Michigan.  

I sent the serial number to Stu, K4BOV, to check its history in the Sacred Swan Database:

"That radio was built in August 1974. There is a little history on that one in the database.
 
It doesn't show the name of the original owner; but, says Sonny Eisenberg, WA9KXQ bought the radio and Swan 117XC for $150 from the estate of an SK. Sonny reconditioned it and sold it in December 1999."

Sonny, W4KXQI've known Sonny (pictured left) for years; he is now W4KXQ and lives in Florida.  Sonny is my hero - not because of his rugged good looks, but in part because he has likely had more radios than I will ever have, and also because he's just a swell guy.  Sonny was gratified that the old Swan ended up in my hands, and reports that he misses his Swan Twins.

By the way, Stu had some information on the Swan Twins as well:

The twins were  actually quite rare - only 600 of the transmitters and 450 of the receivers were  ever built. 

Jeff, WA8SAJ, has a fully operational set of the Swan Twins (picture here) and have only heard a couple of sets on the air.

 

You can find Stu, K4BOV and many other Swan enthusiasts on any of the three Swan Nets:

Swan Tech Net every Saturday 2PM eastern 7235Kcs
Swan Tech Net every Wednesday 2200GMT 14292Kcs
Swan User Net every Sunday 4PM eastern 14292Kcs

 


   W9RAN started playing with RTL-SDR dongles about 6 years ago, and knew they were going to have a big impact on the radio hobby.   But since these $15 receivers only tuned the VHF and UHF bands, he designed a wideband upconverter to make HF coverage possible, and described how it worked in an article in Jan. 2013 QST "Cheap and Easy SDR".   The "RANVerter" as...  READ MORE

   The tube-type Linear Master Oscillators (“LMO”) used in the Heathkit SB-Line equipment is a very stable and accurate means of controlling the frequency in the equipment. Unfortunately, as the units age, many LMOs develop a “warble” when tuning. This “warble” usually stops when the frequency control knob is not rotated. However, accurately “zero-beating&rdq...  READ MORE

   The hamshack is the result of a lot of thought. Featuring four 120V circuits on 200A service, as well as a 240V circuit for the amps, the idea was to have at hand dedicated equipment per band.  About 12 'X 18', carefull planning allows for sufficient room to both work and play.The shack is air conditioned and heated, with numerous switched antenna options for HF/VHF and UHF. &nbs...  READ MORE

   I picked these up at the 2107 Sturgis, MI AM Swapmeet, amidst a pack curious OMs.  What a find!  Jerry replaced the original transformer in the linear power supply with a new AL-811H transformer.  The cosmetic condition of these relatively hard-to-find Gonsets is astonishing.  There is one front panel scuff on the GSB-101, and a few inperfections in the cases (original pai...  READ MORE
