It depends on your definition of term "relatively".
Following some general recommendations does not necessarily solve a
particular problem. That's the point where EE technician differs from
true EE engineer.

Seriously, I think, you should measure both signals on the reciver's
first stage output =96 the level of noise caused by switching regulator
and the level of useful signal.

If you find that ratio unsafe:
-	try to diminish the noise;
-	try to enhance the useful signal;
-	try to shift the noise frequency from the signal frequency and
provide better frequency filters;
-	use better noise-tolerant algorithms;
-	etc
