It receives between 6.9 and 7.4MHz, but it hasn't got a lot of selectivity, which I will try to solve somehow. Also, I want to interface the LO to a frequency counter, so I need to build a buffer amplifier to not load down the oscillator.
Here are some images of the receiver and the schematics so far:
|Receiver circuit board. Antenna input, with attenuator pot seen to the left. Tuning caps on the right.|
|Receiver with shielding in place. Tuning knobs to the left.|
