[QUOTE="Analoguesat, post: 1046449, member: 176362"] Having set the default audio to VB Cable SDR Sharp should already be be configured to route the audio via the VB Cable. Fot WXSat you need to set the radio properties to Wide FM (WFM) and a bandwidth of about 40,000 to start with. This means you dont need to worry about the doppler shift as the wide bandwith accounts for it. These settings in the gear wheel seem to work ok for me. [ATTACH=full]116041[/ATTACH] With this set up you should get [I]something[/I] You will need to manually tune SDR# between each pass. You need to look for the telemetry bars as the screen is building. If you get this far you will get some sort of image. Ive deliberately chosen this extremely rubbish image because it shows a very weak signal but the B&W telemetry bars are clearly visible - and its the very first wxsat signal I ever received! :D [ATTACH=full]116042[/ATTACH] [/QUOTE]
