I used to use SDR for DAB radio in the nexus 7 in the dash of my BMW E46. It didn’t work very well but was closer to being some kind of radio receiver (not trans at least)

#12This 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.
Agree. We need a compact short wave transceiver device actually.
A compact CB transceiver would be fun.

#13> 1 watt transmit can go miles yet sips your phone’s battery
How far can such a device reach in a typical urban environment with the longer antenna?

#151w seems a little limited? A cheap baofeng is 8w.
Those cheap baofeng's are illegal to use where I live on most of the spectrum they can operate on. Illegal to press the talk button anyway. So maybe the 1w is also a regulatory issue.
How does the FCC enforce this sort of thing? Are they listening in to certain frequencies nationally with the ability to triangulate a handheld down to actually identifying someone?

I don't see it as clickbait since the realities of the Android ecosystem is a shared context.
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.

Someone complained, they send someone to check and triangulate, verify that the operator doesn't have the license, then issue a warning or fine.

Most of the time they get a complaint, and they investigate.

You can extend the reach using repeaters. This free app is handy for that https://hearham.com/repeaters
