We're thinking of sending a wideband (say, dc to 50 MHz) signal using FM. The carrier could be in the 500 MHz to 1 GHz range maybe. I can get the VCO. What's a good way to do the FM discriminator these days? I could homebrew a quadrature detector, with some resonator and an XOR gate or a mixer, but there must be some easier way to do it. Not being an RF type, I'd appreciate suggestio...

We're having a giant debate. Some people want to cut holes in nice wood conference room tables and install metal grommets. https://www.cableorganizer.com/metal-brush-grommet/ which I think will look hideous, and get full of spilled coffee and donuts crumbs and get grody around the edges. Sometimes the tables are loaded with food. And nobody has a good plan for how to stash/extend cab...

I'm designing something that uses three L-C oscillators running at a few hundred kHz and would like to place them all on a single compact pcb. Frequency-wise, two of the oscillators will operate within 1% of each other while the third one will run about 50% higher. The signal levels will be no less than several millivolts at any point, probably much higher. As usual, I have a limited ...
