[600MRG] WSPR on 0.4742

[John Langridge]

Can you ID the freq specifically of the carrier?

We have observed for a long time a carrier around 475.645 KHz and try to stay clear of that part of the passband as a result.  strength varies but I seem to remember Merv in KH6 comment that he has seen it also as well as some of the VK's.  The signal looks a little wider than WSPR but I dont think we have ever been successful determining any modulation.


73!

Good evening all,

I have been monitoring WSPR on 0.4742 (dial frequency) the past couple 
of days and have been receiving these stations:

I have been noticing a very strong signal within the WSPR passband which 
looks more like carrier than WSPR.

Who? What mode? Or am I chasing some sort of local EMR / RFI?





I hope the formating work and the table and image make it through. 
Otherwise you will have to look here for the WSPR screen capture:
