New updates for SDR#, libairspyhf and Airspy HF+ (Discovery) Firmware

Airspy has announced the latest releases of SDR# r1702, libairspyhf r1.5.0 and Airspy HF+ Firmware r2.4.0. 

Here's a summary of the changes:

The FM Stereo flag was added in the SDR# API: FmPilotIsDetected.

A new experimental Low-IF mode at a lower sample rate (256ksps IQ) was added across the chain to allow portable devices to operate smoothly without requiring further DC/IQ correction or frequency translation. This mode is considered "experimental" because the AGC has yet to be optimized to accommodate for the smaller bandwidth, but it is already usable as-is with the AGC always on. 

For the curious types, 256ksps Low-IF was obtained by shifting the IF, adding a narrower channel filter and decimating 768ksps by 3. This gives a wonderful number that is a multiple of a known sound card standard rate: 32kHz.

The IQ streaming and command handling were optimized to allow all of this processing to happen. A positive side effect is that the streaming is no longer interrupted by the commands (set frequency, gain, etc.) - and this one is not experimental.

New utility application for Airspy: Spectrum Spy

A new utility app is available for download with the standard SDR# package. It allows the visualization of larger frequency spans by exploiting Airspy's fast frequency tuning capability. The scanning speed is comparable to real spectrum analyzers (may be faster even!) The project is still in a PoC state, but the basic functionality provided is fully operational.
