Re: LF: OPERA overload?

Okay ... now trying putting that signal inside the OP or WSPR bandpass with 100% transmission duty 
cycle and see if it affects your weak signal reception ;~)
I was using your '30 dB' to make a point and added a couple + signs ... will get a more accurate 
measurement for you. On 160 meters I've seen Bob's signal at -20 dBm on a dipole receive antenna ... 
somewhat less on the beverage receive antenna.
