Basic introduction
The 125 MHz oscillator generates a low VPP fundamental signal, which is fed into the ADE-1 mixer. The mixer then combines the input intermediate frequency (IF) signal with the 125 MHz local oscillator signal to produce the desired RF signal through frequency mixing.
The preceding stage uses a 30 MHz low-pass filter, while the subsequent stage selects specific frequencies using a 125 MHz high-pass filter. The 125 MHz frequency was chosen to avoid FM broadcast frequencies, which is also why 100 MHz was not selected.
The results weren't particularly good, and it might be related to my antenna equipment (I was using a U-band antenna, but not a small loop antenna).
