Thanks Markus - we do have the occasional carrier incursion from various power metering Turtle systems but I see what you mean. Ive been running the rx system for a few months and this was the first so far this year on Opds save for JA - the Transpolar openings have been rarer than rocking horse poop.

Appreciate the software- another excellent tool. Coming up to the best times to Eu over the pole so fingers crossed we get a quieter period, and less of the X files incursions.

Laurence,
 
UW8SM is usually a strong signal here but no indication of a transmission at that time and frequency, so almost certainly a false positive.
 
Opds detections with correlation marginally above 15 dB are generally a bit suspicious, especially if accompanied by fairly good carrier SNR (ie. better than 45 dBOp or so). This usually indicates that opds has locked on some spurious carrier, eg another transmission or a Loran line, and the modulation or noise around it happened to resemble one of the listed callsign patterns. If you have a well calibrated frequency readout (better than a couple of milliHz), you can configure opds to ignore lines from specific Loran chains.

Subject: LF: OP32Ds decode UW8SM <?>

Not sure but this decoded - cant see any parallel times decoding on Opera live - just after my dawn yesterday =- don't think its "real" <?> Especially given magsol over the past 48 hours, but stranger things have happened
