Re: Major interference from computer

You did not answer the important questions. Does it stop if the antenna is disconnected? If so what is the antenna, where is it? Alan I disconnected the antenna, and the interference disappeared. Booting the desktop computer did not have any effect near 118 MHz when the antenna was disconnected. I'...

Re: Major interference from computer

I unplugged all cables except power and display cable from my desktop computer while using the RTL-SDR on the laptop, but the interference did not go away.

Re: Dangers of ESD

By hand is fine. The ESD diodes in the dongle can handle that easily. And there is a bleed resistor on the dipole itself. Outdoor ESD from high winds/sand etc may be too high. Direct or nearby lightning when connected to an unprotected outdoor antenna will fry it. Thanks. Good to know that the risk...

Dangers of ESD

Hello all, I just purchased a RTL-SDR v3 stick and the dipole antenna kit. I was wondering if it's safe to adjust the antenna by hand when it's connected to the RTL-SDR. Is there a risk of ESD damage? As a precaution, I touched the computer case (at an unpainted location) to discharge myself before ...
