Title: Updated HDSDR and ExtIO for SDRPlay
Post by: Josh on July 15, 2018, 1915 UTC

We have updated the HDSDR and ExtIO installers available from our Downloads page (https://www.sdrplay.com/downloads) to support the API 2.13 release. The purpose for the ExtIO plugin update is to support the API 2.13 which has an improved ADC overload acknowledgement system. We have kindly been given permission from the HDSDR authors to host the latest version of HDSDR (2.76a) along with the RSP ExtIO plugins to make it an easy installation process. If you already have the latest version of HDSDR installed, you can just install the ExtIO plugins, otherwise just install the HDSDR installer as it contains the ExtIO plugins.

Dunno what all it fixed but my RSP2 loves it and the smeter now actually shows some range of movement. Also same low cpu usage as before. I run low IF mode and 200KHz decimation, with a 10KHz offset as that places the desired signal further from the oscillator phase noise center. I don't enable tuner agc, have the IF gain set at 55, the main rf gain control set one down from max. The gain settings might not be tolerable with a antenna with lots of gain, hf antenna here is a off center fed dipole.

The exit IO plugin is the thing. When i tried running my radio through the HDSDR program posted, your hardware won't run w/o the exitIO driver/plug-in. Good news, thanks for your effort.
