Before you give up completely, try a ferrite bead on power cables, and maybe even the XLR. It sounds silly, but they’re cheap and easy to use. They just snap on the outside of your cables, with no modification needed. So if it doesn’t work, it was only like 5 minutes of work, and like $10.
My bet is actually that you have poor shielding somewhere else in your system, and this is simply being manifested via the mic input having AM radio noise.
You can get a variety pack on Amazon for $10. I’m sure that you could find smaller packs for less if you looked around. That was simply the first result I saw.
Hi Guys, Just a suggestion before giving up and sending it back, have you considered adding some clip-on Ferrite cores onto the cable to see if it suppresses the RFI/EMI noise?
I noticed the my Huion Kamvas Pro 16 cable doesn't have any ferrite cores on the ends of the cable but I personally haven't noticed any interference of ghosting and am not sure if the Pro20 cable is also missing them.
I did notice online that the Wacom tablets all have them on each end of their cables so perhaps they would help?
Amazon sells them in kits for various size cables, like this one:

I really think adding one on each end of your cables along with any other monitor cables you use that might be missing them will help to get a pristine interference free image.
I hope this helps, Good Luck!

I often use a surface pro 4 with aprs. It definitely generates some RF noise though not as bad as some laptops I've used before. Something as simple as a frayed or loose cable can make a big difference though.

Technically yes you could install a filter between the antenna and the handheld, but I don't think thats the road you want to go down. I would start by getting some ferrite beads (anything like this): https://www.amazon.com/Cedmon-Pieces-Ferrite-Suppressor-Diameter/dp/B07CWCSNW9/ref=sr_1_5
Snap them around any or all cables coming out of the surface, see if things work better. If one helps, try two or loop the cord through it a couple times for even better suppression. You can listen on your handheld with the squelch held open and see if the noise changes or gets quieter when you put them on. Also compare running on battery vs having the charger plugged in, sometimes one will be a lot noisier than the other.
