Linux Mint upgraded to 22.3

 recently I did the upgrade of my old ASUS laptop from Linux Mint 22.2 to 22.3 successfully.
The upgrade tools get easier to use each time.
As I said in the past, if you got an old PC or Laptop that is too old and slow for MS Windows, then recycle it and install a flavour of Linux on it for a new fast, lease of life.

Interference across 6metre band in Frenchs Forest area,

 Interference across 6metre band in Frenchs Forest, NSW area

Over last couple months the interference has become worse across 6metre band, more noticeable, whilst scanning the 6metre FM repeater segment, I did a sweep from 46-60 Mhz  and found there is wide band signal covering 52.500 to 57 MHz, the signal strength varies from s5 to s9 across that segment.
I suspect it radiating from Northern Beaches Hospital, possibly some piece of medical scanning equipment.
If scan across  the band with a narrow band receiver, it just seems like white noise, but the signal strength meter shows there is something there. 

This happened a few years ago and I tracked it to the hospital.and suddenly it went away.
