When functioning as a demodulator, the diodes take the IF frequency (455KHz), and the BFO frequency (453.65/456.35KHz), and make audio. When functioning as a modulator, the diodes take the audio, and the BFO frequency, and make modulated IF. A 1N4007 cannot switch at even audio rates, let alone at 455KHz. You could always try a "vaccuum state" diode such as a 6AL5... -- Cheers, Stan Barr stanb .at. dial .dot. pipex .dot. com (Remove any digits from the addresses when mailing me.)
