The satellite described in these 2 articles is the Kawngmyongsong-3,
but the one currently in orbit is believed to be a copy.

I was reading the article in QST January magazine that details turning a
DVB-T usb
TV Dongle into a SDR receiver with coverage from 64 to 1700 Mhz with some
gaps.
I was wondering how this differs with the Fun Cube Dongle being sold. The
article also
shows how to extend coverage to the HF band. The TV Dongles sell for about
20 dollars
on ebay.

I literally just received mine yesterday and am using it now. A member of
the K2GXT radio club here at RIT (Rochester Institute of Technology) just
did a bulk order from China and each one cost around $15 but took a month
or two to ship. It seems to work well for the price and has a roughly 40MHz
to 1.5 GHz tuning range. I haven't tested it but the receiver seems quite
flexible for frequency range but not very sensitive. I'll do some testing
next week. The antenna that came with it is pretty much junk and I think it
uses a MCX connector so I just ordered some MCX to SMA adapters which
should let me seamlessly put a LNA and a good antenna on it which will let
me really use it well. I really hope it lets me listen to the AMSAT birds
with ease, the LNA will be a must. Lastly, there are quite a few spurs on
the bands at first glance.
The circuit is pretty much the same as the FUNCube Dongle, it's even the
same IC inside. The difference is that these units are mass-produced and
are not optimized for operation on anything but strong TV stations. The
designer of the FCD has likely (I haven't seen the schematic) put great
effort into optimizing the device for ham use. The FCD also helps support
the FUNCube satellite.
Hope this helps.

I have the original FCD and the HF adapter. I ordered the new DC to light
FCD a few hours before the December QST arrived.
I have been playing with the dongle for a while. Mainly on the satellites
but have also copied EME JT65 signals with it. On FO-29 and AO-7 it is fun
to watch the whole band pass at once.
In many cases some preselection is necessary (VHF repeater for the gas
company is close by, if you don't tune it out the system is desensed). On
the HF side, a simple LC tuner as a quantum improvement.
SO after the QST article I stopped by Best Buy. Without the benefit of
exotic test equipment a can say I can't tell the difference!!
I hooked up the HF adapter, again can't tell the difference.
Now all I need is a computer controlled VFO!!
