Matt with DISH Network here. The 222/222k will not work with an EHD. The supported receivers are: 211, 211k, 411, 612, 622, 722, 722k and 922. If a customer only has a 222/k on the account, our system will not allow the "activate EHD" option to appear. It sounds like there must have been a receiver that supports EHD's on the account, and that the tag was added in error. If the tech was able to get the 222k working with an EHD, I'm more then curious as to how. If you can post the details on how to get an EHD to work with a 222/k, I'm sure Tony, (who some of you have already became acquainted with) and myself will be busy trying to duplicate the setup.
