Randy ,
I would urge you to call Samsung on your own whether someone else has the ear
or not. This would get you into the records as having a problem with type of
stove.
The more calls Samsung gets from Ham radio operators on this RFI problem, the
less likely they are to not say" We have never heard of that before"
Working externally from the stove, IE ferrite core chokes on the line cord are
ok to try, and hopefully they work. But by all means please do not open the
stove to try to remedy the problem.
This is a critically safety issue. If something should fail inside your stove
and it leads to a hazard, it would be too easy for Samsung to say some sort of
tampering of the stove had led to that hazard.

Hi Dan,
I reached out to you directly after hearing about your issue. I too have this
problem with my Samsung gas stove. For me, the issue is the worst with as
little as 15W on 40M and 50W on 17 and 20 meters.
The first time I came downstairs saw that the oven was on and already heated to
400+ degrees, I knew immediately what happened.
My oven model: NX58M6630SG
If you find a solution on your own that really works, I would love to know the
exact list of parts and methodology you used. If you get the ‘ear’ of someone
at Samsung, PLEASE pass the contact information to me directly off list.
Thanks and 73,
K5RHD
