Weird walkie-talkie interference with Logitech unifying receiver

This is insanely weird, and although it's not necessarily a problem, I'm really curious what's going on here.

I'm running Ubuntu 21.04 and have a wireless Logitech keyboard and mouse along with the Logitech unifying receiver. I'm running Solaar to help manage those. I work for a company that provides a MURS walkie-talkie for work onsite.

This evening, I was playing around and turned the walkie-talkie on and tapped the talk button. My screen went nuts. The application that was open closed, and a string of random text appeared in a background application. I'm not too knowledgeable with wireless technologies, but it seems really strange that my walkie-talkie can cause interference and interact with my PC. Does anyone have any insight on this?

Solution 1:

RFI (Radio Frequency Interference) is actually common. For example from this article:

"The walkie-talkies in the article yesterday are Motorola FRS (Family Radio Service) transceivers and operate in the 400Mhz range (around 460mhz). At these frequencies the wiring in computers and TV sets can act as antennas. The higher the frequency the short an antenna has to be to be resonant. Depending on the power level of the transmission this can cause all kinds of problem with frequency dependent devices - such as monitors, mice, keyboards and the like.

"The frequencies of the two devices can mix and cause problems by adding to or subtracting from the frequencies the device is expecting. This could cause the screen to distort and could also lead to false mouse movements and clicks and well as false keyboard entries.
