Therefore first source was 0605-085, scan_No 309-1816, all scans previous assumed missed. One of the IF's was tripping a silent alarm (no alarm or beep, but seems kinda serious tbh) about having no default value. ifdsx was not fully defined, so just had to fill in ifc=2,agc,2,32500 & ifd=2,agc,2,35000.
