two hr-44 receivers in one location

Unfortunately not. You can only have one main Genie (HR34, HR44, HR54), Genie Lite (H44), or Genie-2 (HS17) on the account as works as a server.

However, you can have multiple H or HR models (or R22) with the HR44.

Thanks.  I thought that was the case.  Have a good Thanksgiving
