Hi Gary,

Thanks for the response.
Well I heard Opera signals here tonight on 501.80, 502.00 and 502.20. You 
may check the Delft websdr (I am using this websdr at the moment as my RX 
ant is not back up yet). These users probably have the wrong TX dialed in?
I still think it would be a good thing to allocate a specific part of 500 
for (all kinds of) beacons. That way interference will be minimized an 
optimal freedom for experimenters (all modes HI) can be assured.

Kind regards,

Minto pa3bca

Hi Minto,

Sorry that you seem to be experiencing a problem from the Opera beacons.

There should be no QRM from Opera as the Tx sub-band is 501.300 to 
501.700kHz & would not interfere with your CW QSO's on 502.000 & 502.500kHz.

Also the Opera software will not Tx on an occupied freqency due to it's 
agile frequency feature, it will automatically QSY to a clear frequency 
within it's sub-band before Txing.

I am monitoring the frequency & I have not seen any Opera signal outside the 
limits which I have mentioned above in this email.

73, Gary - G4WGT.
