Radio History: A Century of Amateur Radio and the ARRL

Episode 31

A comprehensive and fascinating article on long-delayed echoes (LDEs) appeared in the February 1970 QST. LDEs are signals that have been transmitted, go away somewhere, and then are heard -- at low signal levels but often with good readability -- 10 or more seconds later. They were first heard on the ham bands in 1927. An article in the May 1969 QST described them and asked for reports from readers who had heard them. The 1970 follow-up article summarized more than 40 reports. A May 1971 QST article later reported on more than 90 observed LDE events.
The effort to get more amateurs on the VHF and UHF bands continued, with QST publishing articles on 432 MHz transmitters, 220 MHz kilowatt amplifiers, state-of-the-art low-noise receiver preamplifiers, new propagation modes and how to use them, portable beams for 2 meter mountain-topping, and more.
The number of hams using very low power -- QRP -- also continued to grow, with equipment and portable HF antennas featured in QST articles, as well as reports of QRP use by hikers and mountain-climbing hams.

Repeaters for 2 meter FM operation were becoming very popular, and their numbers were growing rapidly. QST described how to build repeater duplexers, control equipment, antennas, and control links, and it kept repeater control operators informed of relevant FCC rules as they were developed.
Amateur Radio satellites continued to attract more and more attention. QST articles provided information to encourage and help hams get up and running on the satellites. Topics covered in those many articles included how to plot satellite orbits, build beams that could be rotated in both azimuth and elevation, construct circularly polarized beams, determine when you can use the satellites for contacts over a given path, along with other tips and information. As each new OSCAR was built and launched, QST carried announcements and information on how to use it.
A nice article on "The $22,000,000.00 Ham Shack" appeared in the April 1970 QST. No, it wasn't an April Fool's article. It told of the first flight of the new Boeing 747, with WA7IBL using one of the aircraft's radios to make HF SSB contacts.
As the 1970s rolled along, many homeowners purchased hi-fi and stereo audio equipment. Most consumer electronic equipment was not built to reject interference from ham transmitters, however. Articles in QST during the 1970s told hams how to deal with those interference issues.
In 1970, the much-anticipated Heath SB-220 HF kilowatt linear amplifier came on the market, with a selling price of $350.
As transistors' performance continued to improve, homebrew solid-state equipment became progressively more popular. QST reported on many interesting projects that used transistors, including VFOs, QRP rigs, receivers and receiver preamplifiers, transmitting linear amplifiers, and accessories.

RESCUE RADIO: Maritime Mobile Service Network Aids in Separate Land-Based Emergencies

While best known for its efforts to aid voyagers on the high seas, the Maritime Mobile Service Network (MMSN) occasionally helps out in land-based emergencies too. That was the case recently when MMSN net control stations received distress calls regarding motor vehicle incidents in Nevada and Texas. On July 24, MMSN Net Control Station Ken Porter, AC0ML, was notified by HF mobile operator George Molnar, KF2T, that he had witnessed a tractor-trailer mishap on Nevada Highway 318. The rig had apparently skidded and landed on its side in a canyon, precluding the use of cell phone or Amateur Radio VHF/UHF systems.
"Truckers' CBs didn't reach anyone outside the canyon. Only ham radio worked!" Molnar said later.
Porter placed the net in emergency status, pinned down details on the wreck, and notified authorities. Nevada Highway Patrol troopers were dispatched to the scene. There were no injuries, but the highway was completely blocked in both directions, and some of the tractor-trailer's perishable cargo ended up scattered on the roadway.

Porter, the NCS, later said that he was "quite surprised" to get a call regarding a land-based emergency but also understood why this might happen, given that the Net's availability on 14.300 MHz daily from 1600 to 0200 UTC, and the fact that many hams are aware of its existence.
Several weeks earlier, on June 18, MMSN NCS Donald Plunkett, VA6FH, was called by a trucker-ham who reported a serious motor vehicle accident involving a truck and a car outside of Stockton, Texas. The station calling in requested that the net contact the Texas Department of Public Safety, since he was outside of cell phone and VHF/UHF repeater range. Emergency units were sent to the scene.

(ARRL Letter)



A historic radio transmitter has been saved from the scrap-heap thanks to three organizations who worked diligently to preserve it. The announced transfer of the Voice of America broadcasting station in Delano California to the General Services Administration for disposal had potentially sealed the fate of the last compete Collins Model 821A-1 250,000 watt High Frequency Autotune transmitters in the world.

Meantime the Collins Collectors Association and the Antique Wireless Association had formalized an alliance named the Collins Radio Heritage Group. Hearing of the potential loss of the transmitter the latter working in cooperation with members of the Arthur A. Collins Legacy Association began campaigning to save some of the significant historical artifacts related to the Delano Voice of America transmitter site.

In December of 2013 a proposal was submitted to the Voice of America and the Government Services Administration to recover, preserve and display the transmitter and the studio control console from the Delano site. This past May the proposal was approved and recovery began. The effort was recently completed with the transmitter, studio board and other associated remote gear being removed and shipped to the Antique Wireless Association Museum in Bloomfield New York where they will be displayed.
