Raspberry Pi RFI ??


Being an Amateur Radio Operator had a local 10 meter net on 28.470Mhz and noticed a strong carrier on 28.472Mhz. Unfortunately the Pi and the dongle antenna are not too far from the dipole I was using. Shutting off the Pi got rid of the problem!

Anyone else noticed this? I suspect that the Pi being totally unshielded is problematic.


Yes very wide band interference around 28.500MHz and you will find on transmit of course the dongle ceases to work.


The dongle has a 28.8MHz oscillator - you may be seeing leakage from there rather than from the Pi itself.


I have found HDMI cables to be a great source of RFI. No problems if you are running headless.
