Mark KI5SRY came up with a very innovative solution for the tuning dial problem. See above. My solution was much less sophisticated: At the suggestion of VK3YE, I just put a calibrated card underneath the screw. By looking at the screw edge from above, I could get a rough estimate of where I was in the band:
Looking back on his successful build of the receiver, Mark wrote:
You made this pretty straightforward. My biggest challenge was trying to understand what was really happening in the circuit.
I learned how to use my oscilloscope, seeing the oscillator come to life was great.
I would like to build a transmitter or a complete transceiver.
Bill, thanks to all of the effort you and Dean are putting into this project. There was definitely a magical feeling dialing in and getting legible sound out something built on my bench.
Very cool Mark. Congratulations!
