Comment on How we found the source of the mystery signals at Parkes Radio Telescope (2015)parent

Not enough to harm you, but how about a nearby device with an antenna?

Would a microwave burst e.g. fry the speaker of a crystal radio (where the antenna bridges nearly directly to said speaker) which happened to be tuned to a radio-band frequency for which 2.4GHz is a harmonic?

Or, for regulated products like 2.4GHz wi-fi routers, does FCC “accepts interference” testing take microwave bursts into account, or are we slowly degrading some component in them every time we open microwave ovens near them?

Anecdata, but for 2 years I have had a Chromecast Audio and a cheap Creative 2.1 system about 20cm away from my microwave, which is the type where you can just open the door to stop it. No problems so far.

Don't microwave ovens in large part depend on standing waves (resonant with the chamber size) to deliver the power levels they do?

Directed microwave energy can ruin electrical equipment nearby. You can find videos of this on YouTube, usually out of Russia.

Whether it'd do the same with a very short, unfocused momentary burst from reflection inside the oven cavity depends on your equipment I guess. I wouldn't leave my hackrf with RX amp turned on nearby, anyway.
