An outstanding show this year.  First off, donating and were asking about plans for next year.  Second, it was often standing room only.  The conference room held 60 seats, most all were taken.  Third, having the presentations span the old (vintage & restoration) and the new (SDR-new equipment performance) drew a variety of people in.  While many floated in and out during the two days, every presentation was “full house” attended and the questions were all solid ones.  We had some great food and good weather.  It didn’t hurt that we had three of Ham Nation’s four key guys here…only one missing was Gordon West.  The Slidell Hamfest was sold out with respect to tables and so the hamfest organizers, too, were quite pleased. 

Holding this near a major city and allied with a hamfest appears to be the key.  People were excited about the many topics discussed as no typical hamfest has this vintage/restoration/homebrewing part. So, back to the discussion we tossed around last year – two venues:  the South (Slidell/NOLA) and the Midwest (St. Louis area, for example)?

   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

Crazy EBay Prices!

Pictures of radio suckerbait on the world's largest online auction!
Category: Crazy EBay Prices!
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 (unremarkable/filthy/nicotine-caked) wares as if they were priceless artifacts of distinction, having immense value.  It is truly within this online marketplace where prod...  READ MORE

   These excellent examples of the Swan Twins are from the estate of John Thuren, AA5T (SK) 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. ...  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

2018 Cave City Hamfest

Cave City, Kentucky, 3/3/2018
Category: Activities
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

   For nearly five years, spanning 1978 - 1983,  I worked as an Electronics Technician in the original Bearcat manufacturing and service facility in Cumberland, Indiana.  Electra was one of the best places I've ever worked, and were among the many innovative consumer electronics companies which sprang up in and around Indianapolis.  Al Lovell, a former employee of Regency (also in ...  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
