This doesn't turn your phone into a ham transceiver at all.
It turns your phone into a transceiver controller.
Given that a cell phone is a transceiver, this headline is rather disappointing clickbait.
I've used a few handheld transcievers and they tend towards clunky user interfaces-- tiny, fiddly displays, highly modal keys, and basically needing to memorize the manual to use it.
Even worse-- there's not a strong correlation between the quality of the RF unit and the user-interface. The Yaesu FT-60 is a reliable, high-quality radio, with all the user friendliness of a live porcupine.
But with a 6-inch pocketable touchscreen you could solve most of the UI problems, and focus on the radio problems.
Keeping the division also gives you flexibility-- you could design a 25-watt tabletop unit, or modules for different bands, that shared the same basic control software and UI
We need a compact short wave transceiver device actually.
And I know, I know, Baofengs are notorious for going over the allowed noise limits… but still…
Several handheld CB radios exist, with little loaded whip antennas. You can go buy one. You'll see. They work for talking between two tractors in a field or whatnot. Past that, not so much. Today, you're better off with license free UHF handhelds for that use case.
I have personally made voice (single-sideband or SSB, which is analog like AM without wasting energy transmitting a carrier or redundant sideband) contacts with a 5 watt portable (Elecraft KX2) between countries in Europe, using a meter-long whip antenna and a trailing counterpoise wire.
These radios are incredibly complex weak-signal equipment, and that is reflected in the price.
That said, it is fun. Using morse code to do the same is even more fun.
I would never rely on this for off-the-grid communication, though.
Handheld CB radios do exist and are cheap, but I've never really used them.
Most people know that just about every Android phone has a restricted hardware design, not an expandable one.
So, "turn your phone into X" is bound to automatically evoke images of another device that plugs into the phone via common connectors like USB or the audio jack and an app on the phone to control that device. That's what the phrase means to most people in the context of Android.
"Turn your phone into a ham radio transceiver controller" is neither needed nor entirely accurate, because then people will assume it can control _any_ ham radio transceiver.
The title is still misleading to me. Not terribly so – hence my not quite serious reply – but I was expecting something like https://timestation.pages.dev/, which actually transmits using included hardware only.
However, your analogy is not equivalent to, nor an example for, what I said. There's a difference between a phone's own USB/audiojack interfaces and a wall outlet.
The two don't add up, and your apologetic analysis doesn't convince me otherwise. It's still clickbait. An Android cell phone has radio guts, and that headline is just gutless.
