[Elecraft] Headphones

[Mark Goldberg]

Have you contacted Bose? They are FCC part 15 and even say this in the user
manual:

This device complies with part 15 of the FCC Rules and with Industry Canada
license-exempt RSS standard(s).
­Operation is subject to the following two conditions: (1) This device may
not cause harmful interference, and (2) this
device must accept any interference received, including interference that
may cause undesired operation.

I think it is incumbent upon them to make them work.

I know they have the capability. Their aircraft headsets have to operate in
very similar conditions. Aircraft have HF radios.

I operate a station in our small RV with a KPA500 and a collection of other
electronics and bluetooth devices, with good bonding and ferrites in
hopefully the right places. Everything works with no issues.

73,
