Hi Vasiliy, It identifies itself as a Hermes FW version 2.4 I was hoping it may be useful for skimmer use. I don't know a lot about it though. -Rick =================== Hi Rich This is great! What Board ID and fw version does rtl_hpsdr send to the discovery request? your solution can be used potentially with the skimmer server and HermesIntf.dll for multichannel decoding. (I don't have a dongle yet to give this a try) 73 Vasiliy
