Hi Folks,
Mike Gruber, W1MG at the ARRL has a reporting referral process for broadband carrier  issues with Amateur Radio that I helped design as a member if the ARRL's ElectroMagnetic Compatibility Committee.  This process provides for clarity when dissecting and resolving either ingress (Ham transmit) or egress (Ham receive) issues.
