I have an ex AM PMR radio that I wish to use on 144Mhz. I need a PSU feeding

Are switch-mode powers supplies alright or are they too noisy to be used for
receivers? TIA.
Some are, some are not. You have a lot of choices available at 300ma.

I tried one that created all kinds of interference. I was able to
solve the problem by installing caps in parallel with the rectifiers, .
005uF disc I think.
