Hi everyone,
I have an Powertech MP3090 40 amp power supply that has quite bad HF RFI issue specially around 7Mhz, as anyone had a similar issue with an earlier version of this power supply and has been able to limit or fix the noise issue. I do know I will need to put in some HF filtering in the DC output to the radio, just would like to know how others have gone about this, the RX is around S7 to S9 so it's quite bad.
I have heard that later versions had fixed the issue
Any assistance and information would be appreciated.
