Is an isolator overkill when measuring a Gunn diode oscillators output power?
Not even the frequency, just power.

The wifi router in your house uses the 2.4Ghz spectrum which is in the upper range of the now defunct UHF spectrum. Wouldn't it be neat if you could tune an old CRT TV to the same channel as your wifi and see patterns?
Unfortunately, UHF channels were much wider so the TV wouldn't be able to pick up much, not that it would know how to demodulate it anyway.
Kinda funny to think we have tiny little TV stations in our houses. 📺
YES!
I did find the right connector.
Sure, it was in the third bag of miscellaneous MIL connectors .
But I found it.
A slight step forwards on the #24GHz #Flexihopper transverter project.
So very used #OCXO oscillator cans from ebay.
They ware cheap and most of them should work.
Plenty of projects of mine and from friends will have nice, stable and cheap reference clocks.
And if there are duds, I get to pull one to bits or possibly learn how to repair OCXO's.
I plan to use one as a refclock for a homebrew signal generator, when I repair and re-home it to a better case.
And for a #24GHz project.
Too make matters worse
Second prize went for a #24ghz #mmwave radar that two dudes brought along from their employer it is used in traffic control.
Idea: to use it for sleep problem detection
So they got applauded and especially highlighted that they transferred tech from traffic to health.
Only, it sounded familiar. I thought ti.com had it as reference implementation

They only plotted distance and said you can see if movement and unhealthy sleep
The MR24BSD1 24GHz radar module applies Dopplor detected theory to implement human sleep quality monitoring providing a fully total private and secure sensing environment, independently from other noisy influences. It is a useful privacy-protected, secure sensor radar systems in smart home applications like sleep safety alarm, sleep respiratory detection.
