I have fldigi installed on my Mac, and a Tecsun 380 shortwave receiver. I'm desperate to decode something! I've tried the CW on 40 meters but all I ever seem to get is random characters. I've tried tuning to the PSK31 frequencies but I didn't hear any PSK31 I don't think, or not anything that sounded like the PSK31 samples on youtube. How can I decode my first digital signal? I have a longwire antenna strung up over a tree and an MFJ 902 between the longwire and the Tecsun 380. I am able to see signals on the waterfall but never seem to be able to decode anything. Any help is appreciated!!!!
