Since 2010, the United States military has been operating a pair of small reusable spaceplanes that conduct secretive long-duration flights in low Earth orbit. Now officially operating under the auspices of the newly formed Space Force, the X-37Bs allow the military to conduct in-house research on new hardware and technology with limited involvement from outside agencies. The spaceplane still needs to hitch a ride to space on a commercial rocket like the Atlas V or the Falcon 9, but once it’s separated from the booster, the remainder of the X-37B’s mission is a military affair.

K5LYN's SB-10/Collins 310B/DX-60 Experiment

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

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!

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

Swan Twins: 600-T, 600-R Custom, 600-S

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

SDR techniques for Boatanchor Radios

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

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

Heath Tube-Type LMO Repair (PDF)

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
