Graham, please set the drive to give -6dB per tone (relative to max output). Since the signals are not exactly harmonically related, their voltages will add "in phase" every now and then and you will
Will be running dual test , JT65-A AND WSPR Friday night , 1800 /2400 ish Frequency will be round 503 Khz , not yet worked out the transmission format as the wspr tx/rx ratio is round 10:1 , and JT65
Yes , I was thinking in terms of peak watts out to Ae 50% 3 dB , but your right on the voltage level, the alc will hold things back over a wide range , but using that, the peak signal to the ae weill
