AIRSPY HF+: AN UPCOMING LOW COST YET HIGH PERFORMANCE HF SDR
« on: February 22, 2017, 1746 UTC »
Preliminary specs:

RX range: 0 .. 30 MHz (HF) and 60 – 270 MHz (+)
Architecture: Hybrid (Direct conversion + DDC) using 2 x sigma delta ADC’s @ 36MSPS
Front end: Tracking Filters (all bands), High Dynamic Range LNA’s and Mixers
AGC: Smart AGC controlled by the DSP
DSP: CIC, CFIR and a final (programmable) channel FIR – 18bit resolution
Final bandwidth/resolution after DDC: 18bit @ 600kHz – Scaled and streamed as 16bit
Image rejection: better than 120dBc
Blocking DR: 108 dB
Separate HF and VHF RF inputs – with option to use one multiplexed input if desired
USB 2.0 with Plug and play – No drivers needed
The RF section resides inside a metal shield
Aluminium enclosure about 60 x 100 x 15 mm^3

Basically, this addresses the lack of affordable and good performing receivers for HF and VHF.
Target price < $200

I'd like to know what the minimum bandwidth will be. Would be nice if it could to 50 kHz for the DGPS band, and not much beyond that.

The R2 is worth the money for VHF so I would recommend a HF type SDR from Airspy. They did a good job. Heck, the front end is better than my Elad S2 sometimes.
All logs made from my own SDRs, boatanchors, and antennas
QTH: vicinity of Auburn, Alabama
