Audio sample rate and bit depth
Show me a human ear that can benefit from even 20 bits/sample. Even 16 bits per sample is likely to be a higher dynamic range than the source material given building HVAC noise (maybe 20 - 40 dB SPL)

SDRdou Diversity mode demo
Inside MFC the arrow key steps are modified by control and shift. The tuning adjustments could employ the same sorts of modifications on the step size. {o.o} On 20230223 13:51:32, Siegfried Jackstien

Satellite tracking 'flip' mode?
I wonder if I guessed right that this happens when the bird flies nearly overhead causing the antenna to flip around trying to track it. (This is why elevation should go something silly like 0 degrees

Depends on whether he wants VLF or below. I've heard, not tested for myelf, that the RX666/888 family is rather numb down there even considering "if the noise goes up when you connect the antenna you'

The logic driving the antenna itself should be protecting it from awkward positions, in a right and proper world. It can understand the dynamics of the antenna and avoid over driving the servos or go

Basically USB 2.0 won't go past 10 Msps and even has trouble making 10 Msps if you are using 16 bit samples. 12 bit samples with a pair of samples mashed into three bytes can work, maybe up to as high

Other intentional emitters are indeed something the receiver must filter out. Nooelec has some filters available. Designs are also available. But somehow I'd hat the impression the discussion was rega

There is an ExtIO file for the HF+ on GItHub. That should make it useable with HDSDR. https://github.com/hayguen/ExtIO_AirSpyHFplus (duck duck go is your friend.) {^_^} On 20230217 04:18:23, Alan G4ZF

Ah yes - for HDSDR the airspyhf.dll for HF+ units and airspy.dll for SDRSharp. Pull a copy from your SDRSharp install for 32 bits. Pull a copy from your SDRC install (c:\Program Files) for 64 bits. Or

Nonononono - you should not have to install a dll for the Discovery HF+. You can mess up your system trying. Plug it in. It should appear in device manager. And SDRSharp should find it as should SDRC.

A BCB reject filter that rejects about 30 dB should provide some relief, if you can find or make one. Alternatively a couple series resonant circuits in parallel, one tuned to each station, should do
