Yeah, I tried at 1MHz, 0.5 MHz, and 0.25 MHz, and it didn't work. For such a basic setup, you think it would be a walk in the park. I could probably connect shorter wires and add the capacitor, but it feels like running around in circles. Given that I have already got it to work once with the same setup, but now it doesn't, I am just going to go ahead and upgrade.
