From Heathkit

Can a VFO from a heathkit Hw-101 be put in an Hw-100?

Can a VFO module from a Heathkit HW-101 HF Transceiver be swapped to a Heathkit HW-100, and if so, are there any modifications neccessary?

Now it’s been a long time since I’ve seen the two units. But as I recall the only difference between them was the dial drive unit.
Electronically they were the same as far as voltage and frequency were concerned.

Popular Electronics is a magazine started by Ziff-Davis Publishing in October 1954 for hobbyists and experimenters in electronics. Which soon became in the "World's Largest-Selling Electronics Magazine".

The circulation was 240,151 in April 1957 and 400,000 in 1963. Ziff-Davis issued Popular Electronics, until April 1985. Gernsback Publications acquired the label in 1988 and her name of Hands-On Electronics. This variety of Popular Electronics was published until December 1999.

A cover story of Popular Electronics could launch a new merchandise or business. The most popular topic, January 1975, was the Altair 8800 computer on the cover and the computer revolution began housing. Paul Allen presented the issue to Bill Gates. He developed a BASIC interpreter for the Altair computer and started Microsoft. Radio & Television News was a magazine for professionals and consultants who want to carry a magazine for enthusiasts only.

Ziff-Davis had begun 1927 Popular Aviation and Popular Photography in 1934, but had found that Gernsback Publications in Popular Electronics brand. Was employed by Radio-Art from 1943 to 1948. Ziff-Davis paid for the brand and started Popular Electronics October 1954 with the theme. Many of the consultants and the authors worked for both Ziff-Davis magazines. Initially Oliver Lee was the conductor of both the Radio and Television News and Popular Electronics. Publisher Lee was approved in June 1956.

Oliver Perry Ferrell assumed the position of conductor of Popular Electronics and William A. Stocklin became conductor of Radio and Television News. Radio and Video News John T. Frye developed a pass on a fiction repair shop where the owner, Mac, merges with other technicians and customers. The student will study amend procedures for consideration of the broadcasting and TV.

At Popular Electronics convey was about two high school sons, Carl and Jerry. Each month, the male offspring would have an adventure that student conference on electronics. In 1954 he erected the structure of audio and broadcasting equipment was a growing hobby. Heathkit and more people than the other proposals in kits that included all elements with the actual instructions. Premier Presentations cover the assembly of a Heathkit A-7B audio amplifier.

Popular Electronics offers efforts met from zero, ie, elements that separate a person paid for in a store impeded or electronic order transmitted by the subject. The subjects often have these principles as the male parent and teen projects. Most of the transistors of the company in early vacuum tubes used; just be available to the amateur.

The Raytheon CK722 transistor was $ 3.50 in December 1954 subject while a 12AX7 dual triode was only $ 0.61. Lou Garner wrote the story aspect for the first item, a storage battery powered toyota tube of parts, Locomotive Broadcasting parts that could be used on a bicycle. Later was given a pass called Themes Transistor (June 1956). Transistors long before costs less than a dollar and the transistor company became universal in all issues of Popular Electronics.

The pass was renamed in 1965 solid state and ran under his byline until December 1978. As editor, Olivier met Ferrell an unwavering authors makeup raises fascinating projects. This work established the approach of Popular Electronics in the coming years. Two of the authors most prolific were Daniel Meyer and Don Lancaster. Daniel Meyer graduated from Southwest Texas State (1957) and became a practical operator of the Southwest Research Institute in San Antonio, Texas. The recently started writing articles for amateurs.

The first was in Electronics World (May 1960) and the second before he had a 2nd part to cover aspects of Radio-Electronics (October, November 1962). The object of March 1963 Popular Electronics embraced innovation assuming ultrasound on the cover. Don Lancaster graduated from Lafayette College (1961) and Arizona State University (1966). A 1960s fashion was to be guarded with parasol colored lights synchronized to music.

This psychedelic lighting was done by the economic development of the silicon controlled rectifier (SCR). Party the first issue of Don was "Solid State 3-channel color organ" in the April 1963 issue of World Electronics. He was paid $ 150 for history. Efforts in Popular Electronics altered vacuum tube solid state in 1960s. Circuit tubes used a metal chassis connectors, circuit of transistors on a circuit work better cast. They often include components that were not available in the store of electronic elements that impeded.
