Not sure why, but even after doing this fix I get no receive when I hook up to antenna. I should easily be able to hear WWV or FT-8 but nothing. All I can hear is a high pitched whine that only goes away when I disconnect the demodulator from the audio amplifier section. I know that the signal is propagating through to at least the demodulator stage (after the 11 MHz filter). It was pretty hard to see if the 11 MHz signal was being converted to audio at that point with the spectrum analyzer or oscilloscope.
