THE VACUUM TUBE’S FORGOTTEN RIVAL

Magnetic amplifiers, the alt-tech of the Third Reich, lasted into the Internet
era DURING THE SECOND World War, the German military developed what were at the
time some very sophisticated technologies, including the V-2 rockets it used to
rain destruction on London. Yet the V-2, along with much other German military
hardware, depended on an obscure and seemingly antiquated component you’ve
probably never heard of, something called the magnetic amplifier or m...  READ

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...

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...

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

when tuning. This “warble” usually stops when the frequency control knob is not
rotated. However, accurately “zero-beating&rdq...  READ MORE
