For all tinkerers who like to push the limits...
What is the highest frequency signal you've managed to generate from circuitry built yourself? Merely applying power to a pre-made oscillator module or a radio doesn't count, and no fair microwaving your lunch and claiming that. From a circuit of discrete components that wouldn't oscillate on their own. Whether for radio purposes or otherwise.
Is it fairly easy to get into the higher realms of microwaves? Has anyone at a more or less hobbyist/tinkerer level ever gotten up into THz?
If you have an interesting story about any such attempts., please tell!
Personally, many years ago i was messing around with some 74LS series TTL chips, and got an inverter with a tiny handmade inductor and using stray capacitance to oscillate at somewhere over 30MHz. Unimpressive by radio tinkering standards, but it was really pushing digital logic for the time.
