The only odd thing that has shown in the last weeks is linked to Fire-Fox and the PSK-Map , being flagged as a un-safe site , opera call's pskmap n .html , just checked on this pc and f-fox opens the map as normal .. but that seems to be f-fox issue related problem as on the pc that runs the mf set up , it still comes up with some un safe site warning ...
But a google search 'opera malware' is bringing back issues with the web browser , that has the same name , that looks to be where the problem lies , [although the name is the same , the browser logo is registered , not the name] could be a serious breach as some of the web-article's state , the certification code has been compromised and some networks have been attacked ..
There's not too much to set up , unpack , run install and populate the locator /call / info fields, VLF wise , no need for the RX just direct to the sound card
But for 8K rx , I think some form of bandpass filter before the sound card , to stop the mains frequency may help , its not a DSP issue , but if the hard wear is topped out by mains hum , the noise floor will rise , simple cr filter would do ..

I understand the software is popular in Europe, but I have avoided it so far due to concerns about malware. OPERA seems to have some cautions regarding this issue, according to what I have read.Any advice you could give me regarding a quick way to set it up and get it working would be appreciated. I will be trying this experiment on my secondary computer (that has nothing important on it). The receiver will be an ICOM R75 run through an AMRAD VLF converter with an OCXO for stability. I have dual 250Hz CW crystal filters installed in the R75 (though OPERA mode may require an SSB filter) as well as the TCXO option.Perhaps I should try to receive some other OPERA signals, to make sure my receive setup is working properly, before I try for your VLF signal?73 Doug KB4OER<<
