I am flagging down all Turkey related threads these days. I don't see how political debates about the failed coup is a subject to be discussed on HN.

There's potentially an interesting discussion to be had here about the technical and political effects of ham radio during disruptions in "official" centralized communications systems, e.g. during a coup or counter-coup crackdown. But of course we're just getting a "Turkey politics 101" thread instead.

If you broadcast amateur radio, is it possible to 'hide' from enforcement? Are there mechanisms that an enforcement authority can use to find your physical location? Is it possible to ostensibly rebroadcast a government-approved channel, but with additional stenography or mixing to embed information?

Depends on how long you're transmitting for. If you're transmitting to repeaters (which take in a signal on one frequency and rebroadcast on another), the time required to find you will go up.

Law enforcement can triangulate ham radio signals. From what I understand it's relatively easy to do in the US.

Earlier quoted context omitted.

Unfortunately, the people of Turkey were going to be screwed no matter how the coup went. If it had succeeded, they would have got a military dictatorship. Now they get a different kind of dictatorship instead. Erdogan was slowly evolving into a dictator before the coup, and now he's accelerating that process. I wonder if the best outcome for democracy in Turkey would have been a attempted coup which resulted in Erdo…

I just can't wrap my head around the fact that it can happen like this, wide in the open with everyone watching. Before the coup I was already amazed that I heard news about he taking over a critic newspaper and the next day publishing pro Erdogan propaganda, it's just beyond belief what is happening. https://www.bloomberg.com/news/articles/2016-03-04/turkish-g...

Well, the world also watched as Hitler unfolded.

Who knows how this is gonna end? Pass the popcorn...

Yes, it's unimaginatively called "direction finding". Hams often do it as a sport, and sometimes to locate unlicensed operators causing interference.

Absolutely possible, though international amateur radio regulations prevent the concealing of information in a transmission.

Tracking radio transmissions is pretty well established and is even a sport for some people. https://en.wikipedia.org/wiki/Amateur_radio_direction_findin...

Hide? Not really. Triangulation is very trivial with the right equipment. All you need is two directional receivers that are separated a bit. Rotate each one until you get the strongest signal from the broadcaster you're looking for. Now draw two lines on the map based on those two directions and you've got your probable point of origin.

You could do something like relay your signal - but your relay will be found. You could be on the move, but every time you broadcast you give away your location.

I'm not sure about Turkey, but in the USA if you're a Ham, you had to supply your address to the FCC. So if the same is true in Turkey and the ham didn't lie... well they already know who you are and where you live.

This is going to end poorly... False flag or not, the coup has given Erdogan an excuse to flush out and exterminate all who oppose him. Anyone want to take bets how long until NATO will revoke Turkey's membership?

> Anyone want to take bets how long until NATO will revoke Turkey's membership?

Well, Erdogan's regime is threatening to end its friendship with the US if Gülen isn't turned over, so any termination of the relationship may not come from the NATO side.
