The past couple of days I have noticed the noise level on the K3 has gone up a couple of S units and on 20 meters and there were tunable hash signals. I started to try and find the problem and using another receiver I find the Astron SS-30 is generating all sorts of noise. I have used this supply for some time and have not noticed the noise before. I drug out an old backup supply MFJ-4245 and behold it also has a lot of tunable hash signals on 20 meters. Wonder what supplies are being used with the K3? Or if anyone has had luck on cleaning up the switcher supplies like the Astron? I suspect it could be due to age and caps going bad, the supply has been in use for 8 years. There are no locally available parts so before I try and recap and order ferrites etc like to know what works if anything.
