Many thanks to a number of SWLing Post contributors who’ve shared a link to this excellent article by Denny Sanders in Radio World Magazine about the history of the Zenith Transoceanic:
Zenith Trans-Oceanic Radio in War and Peace
This iconic portable receiver was known for durability and quality
They say necessity is the mother of invention. Nothing proves this more than the story of how the iconic Zenith Trans-Oceanic portable radio receiver came into existence.
Commander Eugene McDonald (1886–1958), the founder of Zenith Radio, was a stickler for quality and insisted that any Zenith product represented cutting edge technology and design integrity.
He was also an accomplished yachtsman. During his many ocean voyages, he constantly was frustrated with the inability of any portable commercial radio set to perform reliably at sea. In about 1939, he ordered the Zenith R&D department to come up with a rock-solid, portable AM receiver sensitive enough to pull in signals from great distances. He insisted that the radio be a multi-band unit including shortwave, marine and aircraft bands.
The Zenith crew came up with a gem: the Trans-Oceanic, a gorgeous piece of engineering housed in a robust and dramatic cabinet designed by the brilliant Zenith industrial designer Robert Davol Budlong.[…]

LONDON — The BBC World Service, available on radio, TV and online, is part of one of the largest news organization in the world, the BBC.
The weekly reach of the World Service on all platforms accounted for 269 million (up from 246 million in 2015–16).
[…]Large numbers of the BBC’s audience still need international radio broadcasts.
[…]Right from its late ’90s inception, the development of Digital Radio Mondiale was fully supported and enhanced by the BBC World Service. DRM was seen as an efficient replacement for the analog AM transmissions. When we consider scarcity of spectrum for new uses and appreciate the characteristics of the radio broadcast bands, we recognize the tremendous properties these continue to offer broadcasters to deliver programs over sometimes very large distances and areas or in difficult terrain.
[…]The BBC is keen to exploit DRM in order to deliver, to key markets, BBC content free of gatekeepers in a form that can be accessed easily.
For that to be possible, the multi-standard receiver chip is required, and manufacturers must appreciate and act on this global market potential.

GatesAir is suspending the sale of new AM transmitters.
When a prominent radio engineer passed along word to Radio World that he’d sought a quote from the manufacturer on a new transmitter but was told the company had discontinued the model and was assessing its AM line, we sought to learn more.
Chief Product Officer Rich Redmond replied: “Recent changes in the long-term availability of critical components from our suppliers, including several last-time buy notices, have caused us to take proactive steps to ensure we can meet our continued support obligation of our AM products,” he said.
“To safeguard our ability to offer an ample supply of spare components — and to secure the ongoing field support of our AM transmitters — GatesAir has taken the responsible step of suspending new AM transmitter sales, and will instead focus on supporting existing customers’ transmitters with our available components.”[…]
