Would like some info on using this on non-Mac computers #61

I have a Dell laptop, and couldn't find a frequency that I could tune to on my portable Panasonic radio to pick up its bus signal to start with, something I'll need to do before I start trying to intentionally modulate that bus signal. I haven't compiled the program here (which I think is for a Mac anyway) but I have used the online version on the webpage you linked to https://fulldecent.github.io/system-bus-radio/ which I assume runs a Javascript version of the program. I tried listening finding the signal first in the AM broadcast band like you mentioned, and then expanded out to shortwave band (1.6MHz to 29.995MHz) on my multiband portable Panasonic radio. That's a wide range of frequencies in SW, so I tried some frequencies near 2MHz, 10MHz, and 20MHz. I didn't find the bus signal. Any idea what frequencies I should be listening to for a Dell laptop, to find its bus signal?

Please try again in the AM band, but let's focus on the antenna. Do you have a whip/loop available? To get started on my laptop long ago, I literally wrapped the whip around my finger (to focus it, I think) and put my finger immediately on the keyboard between the 4 and 5 numbers.

Your location will be different but there will some location that makes better radiation than another.

Also please do try the compiled program. What we are doing is the browser is running an expensive tight loop. All the browser makers are looking for ways to optimize out these types of things so they will use less energy (i.e. radiate less energy).

Interesting. Does your program compile for Linux only? I'm using Windows, so i would need to be able to compile it for Windows.

I haven't done it. Can anyone else chime in here?
