On my flex 5000A I can hear transmission of radio Ljubljana, transmitting on 918 MHz AM.
The identified frequencies with this interference are: 5222, 7062 (ham band) and 25439.7 MHz.
The 300 kW AM transmitter (night) is appr. 20 km from my location.
My antenna is 20 m end-feed random wire.
I do not hear this intf. on my other analog receivers. Any explanation?.

Hi Jurij,

It's nice to have a calibrated dBm reading from an offending signal.
What level do you receive (the fundamental) of the 300kW transmitter
at 20 km?

Here's some info:
