Preamp success!

Last night, as a line of severe thunderstorms were making their way into Kansas City, 6 meter opened via ducting. I started hearing stations from North Carolina, Virginia, British Columbia, and a lone contact from Montana. I tried to make a contact to one of the North Carolina stations, but just as he was coming back to me the band took a deep QSB fade. I could see a faint trace on the waterfall, but the audio was unintelligible because of the atmospheric hash. I thought I would go ahead and add the preamp, not expecting much help. I was totally caught off guard by the result. The signal instantly increased and the voice of the Ham came astonishingly clear through my headset. Q5 copy. I had expected all levels to come up, including the noise. The only thing that appeared to increase (to me) was the real signal. Great job Flex! What a joy to operate the 6300 under very adverse conditions!
