Its possible, to be spotted by the dynamic system and never actually TX, ie , by up loading a call , hence the system cross checks with other users for a time match, but this is the downside of the extra 5 or 6 dB gained by pattern matching , [136 and 477 only] , that's the same for any correlation system 73-G example of time stamp quality check , g4wgt has decode at 1929 , DL-SWL has detection, the spot times meet the check limits = ok 19:29 477 G0NBD de DL-SWL Op8 569 mi -32 dB F:10% in 1502,2 Hz 19:29 477 G0NBD de G4WGT Op8 21 mi -9 dB F:19% in Chorley, IO83qo, 1511.2 Hz Ik1HGI decode with DF8UO , then qty-3 dynamic spots at the same time = ok as well 19:37 477 IK1HGI de DF1VB Op8 Deep Search -36 dB in Dortmund 1496,1 Hz 19:37 477 IK1HGI de DF1VB/1 Op8 Deep Search -34 dB in Dortmund 1496,3 Hz 19:37 477 IK1HGI de F6CNI Op8 Deep Search -35 dB in JN19QB 19:36 477 IK1HGI de DF8UO Op8 -27 dB F:14% in Karlsruhe random noise has triggered g4wgt by vk - '??' = false g4wgt not sending at this time 18:29 477 G4WGT de VK3XHM Op8 Deep Search ?? -37 dB in Melbourne Australia 1503.4 Hz '??'
