Is this something the Engineers at Icom designed the IC706 for ?

There's nothing specifically banning it in the UK licence, but I don't know about the US Part 97. It should be banned in amateur bands since it's antisocial - and like all frequency hoppers, wastes spectrum.

'....radios are vulnerable to interception and jamming".

Well, of course amateur signals can be intercepted.  That is why they are not encrypted.  As far as jamming, well, that is not an ordinary problem, and certainly not one that should be 'fixed' by increasing spectrum usage and interference.

I've used hoppers elsewhere and a fast hopper is actually a joy to use and makes spectrum sharing much less of a cat fight and done properly, actually exhibits system gain. Without special equipment most hams would never even know that a either fast hopper or direct sequence spread spectrum was sharing the band - really.

However, the last few lines of lawyer-speak on the web-site ruined it from even a light hearted discussion.  Seems that the Oz government sees this in the same way that the US government went after 'strong encryption' outside of their control: as a weapons system, not to be exported without special (read 'expensive') permits.

Oh well - I would have probably only used it for QRP CW rag chews with my friends during contests anyway...    Grin

Unfortunately, jamming by lids is becoming an increasing problem in DX operations. I saw something in the QRP subband on 40 last week looks a lot like Skippy, but with a narrower bandwidth and a higher hop rate. Wonder what it was?

Frequency hopping is a form of spread spectrum and as such is prohibited below the 440 band, including all of HF.  It is permitted on 70 CM and up.
