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 501.700k= Hz & 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 agi= le 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 outsid= e the limits which I have mentioned above in this email.
