I notice up to a +10dB pop on the leading edge of cw elements with my Omni 6+. Please see a recorded waveform at http://n1eu.com/omni6agc.gif and the accompanying 20sec recording is at http://n1eu.com/omni6agc.wav It's clear that when there's been no signal for a second or so, the big 10dB pop is much more likely. Otherwise there's a "little" pop of 3-5dB. I'm not seeing much in the archives but has anyone tried to tame the "pop" via AGC time constants etc? Can anyone contribute a little technical analysis? I see little difference in the popping with fast vs slow AGC. Thanks & 73, Barry N1EU _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec |
