Hi I'm a newbie to the Flysight and have trawled through the forum & threads etc. I've downloaded the latest Flyblind Config, audio etc. then updated the file with my DZ Co-ordinates and DZ elevation. I'm testing it out (at home - some way from the DZ). When I turn the FS on, it does the audio test, but then settles into repeated random pitched noises (low/high beeps....like a bad tune). Not sure if i've screwed the config..... Can anyone help?
