Thanks to the efforts of Nathan Towne, we now have the ability to use [the SDRplay RSP] with Radio-Sky Spectrograph (RSS).
[…]As with RTL Bridge, a intermediary program sits between RSS and the receiver. This program was written by Nathan Towne and is named SDRPlay2RSS, not too surprisingly. This is a dot NET program and if you are up to date on your dot NET run-time updates you should be fine. Installation is a no brainer as SDRPlay2RSS comes with the RSS 2.8.18 update. SDRPlay2RSS does not come with the current full install of RSS so you must do the Full install and then the Update.
