Check Out the National NC-183D!


Recognizing Radio Amateurs 0 Comments 12/17/2017 

Thanks to Jerry, K9GAS, for this superb example.

In all the years of my collecting, I've never seen a finer example of the National NC-183D receiver.  From around 1956, this 17-tube receiver is positively beautiful.  The paint shines like new.  The tuning and meter dials are crisp (most are faded and/or discolored).  Hooked up to a worthy speaker, the push/pull 6V6 audio is in a class by itself.  In fact, the powerful audio is the best thing about this big band cruiser, next to its stunning appearance.

Jerry, K9GAS,  has carefully recapped this receiver, which has no discernable hum or distortion.  Sensitivity is par for the period.  Sideband is of course a touchy proposition: careful manipulation of the RF Gain is required.  Selectivity and Phase controls work well, and there is no indication that this one needs alignment.  But, oh - that audio.  How can one describe it?  It's like enjoying a real cup of coffee from a Seattle cafe, after having to endure the stuff from Speedway for years.  It's easy to forget that dimension to shortwave listening.

You vintage sideband guys, know this: the AM crowd has lots of very serious collectors and restorers who are committed to keeping this old gear preserved.  Thanks Jerry!


   Below is a picture of my latest project.  After doing the transceiver thing, with a CE20A, mated to a SX-115, then the next transceiver project, a 10A mated to any Drake R4 series receiver, I had an idea.  Those transceiver projects have a lot of oscillators, and even the crystal oscillators can drift as they warm up, which requires re-zeroing the transmitter to the receiver from time to...  READ MORE

W1LSB Finds an EBay Treasure

This 1964 WRL catalog was addressed to Major General Butch Griswold – K0DWC
Category: Vintage Manufacturers
I was first licensed as a novice in 1958, and the WRL catalog was really dominant in those days, with the Globe King, Globe Champ,  and all of the lesser models gracing its pages.  I had a Globe Chief 90 and often dreamed of owning the bigger iron in those pages.   I have since collected most of the WRL catalogs from 1954 to 1964, and the last one turned out to be an interestin...  READ MORE

Below are some screen shots of incredible prices demanded by some EBay vendors.  Since posting an auction is free as long as the item is not sold, it costs nothing for the unscrupulous vendor to display their (often unremarkable) wares as if they were priceless artifacts.  Enjoy. ...  READ MORE

   These excellent examples of the Swan Twins are from the estate of John Thuren, AA5T of Houston, Texas.  John had checked in to the 20M Swan net with these very desirable "big Swans" until a few years ago. A big thanks to Eddie, NU5K, who handled John's estate and placed these on EBay.  He packed them well, knowing they are indeed an important find.  Also...  READ MORE

   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

Barry, AC9NK and I attendended the 2018 Cave City hamfest, which was awesome this year.  The facility was packed, with lots of vendors.  We enjoyed the company of my friend Tom, N4LID for dinner the night before. Tom, who is blind, had not been able to get to the hamfest for many years.  You will find more pictures at the Kentucky Phone Net site.  A big thanks to Rod, N4ZIF, fo...  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
