[Elecraft] Headphones

[Mark Goldberg]

I do want to understand what "must accept" means. Why did the FCC put #2 in
there?

I'm from the avionics industry. We have to not produce unwanted RF
interference and we have to operate correctly in the presence of high
levels of RF. Especially in recent years, someone could put their phone
down on top of your unit and subject it to huge fields. We test in fields
of hundreds of volts per meter and have to work.

My products also have to work with 4V of ripple on the power input with no
effect.

Bose knows how to design for these environments. I was on regulatory
committees with people from Bose and they were very sharp. So, if they are
not obligated to fix this, I was just suggesting that they still might if
contacted and that they have the knowledge to fix it.
