The issue of false detection/real call signs is addressed in the Opera Dynamic system and the system output, clearly indicates when the spot is Opera or Dynamic, validated or not. False opera decode = call sign format 'random characters' False dynamic detection = call sign from list , wrong time stamp Deep Search ?? = Not Validated In the case of a non-validation '??' , its to the users to evaluate the situation , was the station sending ? is the frequency that of the detected station ? is the time stamp aligned with the expected Tx ? Issues with the psk-map seem to be a common theme, the system uploads have not changed , but map-housekeeping routines could be removing swl markers 73-Graham G0NBD -------------------------------------------------- From: "John Gibbs" Sent: Monday, January 18, 2016 4:28 AM To: Subject: LF: Opera decode > Decode from LA4ANA just after local sunset here.. was this station even > on air at 18_0141 utc ???
