I just caught that. Switcher???
I've got to see the filter on this. Of course you would not get away with that on any transmitter of significant power. Well maybe FM.
But I'm getting the pdf and I got the one in noise figure. Reading it now. I see what they are saying. Inner band IMD. I'll go along with that.
Look into Mu-metal, makes a good shield for switch supplies. Then you just have to filter the DC.

That R3030 was a real nice radio. At the time it sold for about $10k, military will pay anything I guess.
