The quality of reporting in this article really sucks. The printed circuit boards on top of the tins are not 'telegraph keys', they're the transmitters and the white box is the iPhone interface. Quite where the 'sodium clouds' come in I have no idea because in thirty years of ham radio operation I've never seen one, heard of one or used one to make a contact with a fellow ham.
I agree about the bad reporting. I am left with more questions than answers from this article. Is it the RF side that is interfaced? Are the apps on the iPhone communicating with an OSI level 1 and 2 interface that is the ham radio, or is the ham radio being controlled, as in CIV, through the iPhone with communications going through the air. Or are they just using the iPhone as a microphone and speaker for the ham radio? It is nice to see a "good bit of publicity for us operators" *, but this article literally has no useful information. That's my opinion and I am unanimous in that! 73 de ve3id * Hancock, Tony: "The Radio Ham", BBC 1964
