No sense just "talking" about it. Here's a video of the scanners side by side in operation. The results may surprise you--they sure did me!

That's just not true.There should not be any RF coming from them.
That's just not true.
Almost every radio, even receivers, have RF emanating from them.
See here:
Local oscillator - Wikipedia
And here:
Beat frequency oscillator - Wikipedia
Heterodyne - Wikipedia
Two - or more - of these oscillators can interfere with the others.
Remember those small boxes you could put next to a transistor radio to hear police calls? Similar principle.
Nope, that must have been before my time. These are way beyond transistors, the RF produced by these radios is too small to make any difference. Besides I had the same results before I put the two radios next to each other for the video.
Just curious what was the squelch set at on both radios?
I used to laugh when people would warn others that police could detect if you had a scanner radio in your vehicle by picking up RF emmissions from the scanner. I'm thinking no! Just an urban legend, total myth. While it is true scanners can emit some level of RF noise, police cars were never equipped to detect this, nor was anyone ever busted using this method.
As a side note, England has used TV Detector vans for decades to determine if a household is using a TV set without paying the annual TV viewing license fee. These vans are able to detect the RF emissions of a TV set while it is operating, as well as using other possible detection methods.

Kinda reminds me of the 70's CB days hey goodbuddy I turned my squelch up how do you hear me now comeback.
