SDR receivers and transceivers

There is a real gap in my knowledge as I have never once tried an SDR based receiver or transceiver. SDR dongles are very low cost, so I really have no excuse.

On the Southgate site I read news of a new SDR 5W transceiver.

Handheld of the future?

See http://www.southgatearc.org/news/2015/february/ht_of_the_future_at_orlando.htm#.VNi6BC4WKPc .

Southgate News reports that Bruce Perens K6BP will be demonstrating a handheld platform that can cope with many modes at VHF/UHF at the Orlando Hamcation in Florida. This looks like a demonstrator at 100mW RF. With SDRs, quite a flexible, and low cost, architecture is possible.

I wonder which of the “big names” will be first to market with a real SDR design? This could enable them to sell very low cost units, but maybe they would rather shaft us and make big profits?

Very low cost 70cm UHF handhelds

See http://www.southgatearc.org/news/2014/october/price_of_70cm_handhelds_falls.htm#.VDP48MnTCSo  .
This is incredible: a 5W handheld for less than £8.

Looking on eBay, just £6.99 ($11) will buy a 70cms unit with charger from Singapore. Tell  me, how can ANYONE make money on these?
