[Elecraft] OT noise on 17m

[David Anderson]

Bob,

Most probably a switched mode power supply somewhere locally, almost everything we see repeated at regular frequency intervals like that are harmonics of SMPS. Often up to VHF unfortunately :-(

Have you tried switching off the house breaker and listening on batteries to be sure it isn't self inflicted?

It could be anything from a mobile phone charger to a grow light ballast.
