Sixty years ago this month, the August 1963 issue of Popular Electronics carried the plans for this outboard BFO, dubbed the “Code Bander.” The two-transistor circuit would add CW and SSB capabilities to any receiver, making them useful for the novice ham. No internal connections were required to the radio, because this BFO operated not […]
The handsome transmitter shown here appeared 70 years ago this month in the April 1953 issue of Radio News. The designer’s name is probably familiar to our readers, since he was a prolific author of radio construction articles, and was in the electronic kit business, Hartland Smith, W8VVD, later W8QX. We’ve previously featured many of […]
Sixty years ago this month, the September 1961 issue of Electronics World showed how to put together this simple handheld transceiver for 15 meters, dubbed the “Simple-Talkie.” The designer was none other than Hartland Smith, then W8VVD, currently W8QX, whom we’ve featured previously. With a short piece of wire serving as antenna, the range was said […]
Fifty years ago this month, the December 1970 issue of Science and Electronics showed how to make this one tube VLF receiver with a tuning range of 13-28 kHz. The set used a 6U8A dual triode-pentode, with half serving as regenerative detector and the other half AF amplifier. The tuned circuit used two fixed capacitors […]
Yesterday, we showed a regenerative preamplifier from 1968, designed by Hartland B. Smith, W8VVD, currently licensed as W8QX. We promised that we would bring you another article by this prolific writer which appeared ten years earlier, in the September 1958 issue of Radio Electronics. Smith begins the 1958 article by pointing out that he had been […]
The young man shown on the cover of the September-October 1968 issue of Elementary Electronics, along with his loyal beagle, are taking a break from baseball to pull in some DX on their Heathkit GR-43 portable shortwave receiver. But the portable was pulling in DX from all corners of the world, since it had been effectively […]
Readers of this blog might remember the name Hartland Smith, W8VVD, currently licensed as W8QX. We previously featured his steam powered transmitter, which appeared in Popular Electronics in 1965. A number of his projects appeared in PE and other magazines, and the one showed here appeared in Popular Electronics 50 years ago this month, October 1967. […]
QRP’ers wanting to get on the air with a novel power source will appreciate the steam powered transmitter that appeared in Popular Electronics fifty years ago this month, July 1965. The author, Hartland B. Smith, W8VVD, describes a one-transistor crystal controlled transmitter with a power output of 10-15 milliwatts, powered by a DC motor attached […]
