Without getting overly technical this new model will allow you to listen to HF from 500 kHz right on up to 24 MHz by making a selection of the Q branch within any supported frontend.
The previous editions also allowed you to listen to HF but you needed to make some modifications to the PCB.
Now If you want to listen to DX on 80m, 40m & 20m... No problem. Feel like listening to world news as it happens and unfiltered...No problem. How about listening to clandestine or Military operations...No problem. Listening to HF communication is just one feature that was added. You can still receive transmissions from 30 MHz up to about 1.8 GHz.
What I mentioned above is just some of the additions added to the v3. This dongle packs a lot of punch for $20.00. Everyone says that the RTL-SDR'S "Allows you to get your feet wet in the world of SDR'S" Which is true but with this new v3 you get so much more for such a small investment. $20.00 is nothing compared to some of the prices of HF SDR'S. Don't expect the v3 to match up head to head with a $700 SDR with a 16bit ADC. One thing I will say is that the new v3 edition can hold it's own and actually quite well.
This one is without a doubt staying in my collection. rtl-sdr.com has a great product. I can't say enough good things about this company. They took a run of the mill 820t2 and made it into something worth using and enjoyable. With the right software and antenna you have a complete coverage SDR for 20.00
