Putting up several of those around your SDR... could they be the possible cause of USB connection issues?
I have 3 running, and I assume they broadcast continuously (Since they begin charging a device as soon as it is placed in the holder. There's no physical contacts, at least none visible, between the device and the charging pad. Only the EM field)
And since putting them up I have had the SDR, that sits at the end of a 10 meter long USB cable (Two 5-meter cables, one is powered (From the USB port, not external power source). Technically over the 5-meter limit of USB, and I can't run the Airspy on that cable, but the 'cheap' SDR is just lean enough on the data throughput for it to normally work without the connection being dropped), drop out several times.
SDR# just stops and I have to press the play button to get the SDR running again. It doesn't crash, it just acts like the stop-button was pressed.
When I try the Airspy on that cable it won't even begin to play (And if it does it stutters wildly and stops within seconds)
So, could those 3 Qi wireless chargers possibly be what puts the noise/interference over the limit for the 10 meter USB cable, and be the cause for SDR# simply stopping?
I have been running this long USB cable for over a year without issues, until now where the Qi wireless chargers have been put in use.
I recorded a 30 second video of the spectrum between 100-200 kHz (With no filters to block that area, and with a long-wire antenna running along the floor inside. The antenna is not actually near any of the chargers. The closest it gets is within about 1.5 meter (4-5 feet) to one of them)
I get a signal around 125 kHz, but it doesn't appear to be a very strong signal (The chargers claim to broadcast at 10 Watts, but I don't know if they can alter their power in any way)
I'm not sure it IS the wireless chargers that generate that signal though, because I have an LED TV that generates a ton of noise all the way up to over 10 MHz (With a very prominent signal around 75 kHz that looks a lot like the signal I get here at 125 kHz), so there's a chance this new signal could come from a neighbor instead of the chargers perhaps.
Anyway, I'm asking here in case others have already 'been there', so to speak
