The section "Identification and Protection of Incumbents" requests:

What services are being provided by part 15 devices and amateur operations in this band? Can they be accommodated in other spectrum bands? What are the costs for relocation and how long would it take? We also seek comment on the status of any outreach with part 15 device users and amateur licensees.

I'm only a prospective operator on 33 cm for now, but others here may have the expertise to make an informed comment about investments in operating on this band and potential impacts of regulatory mandates imposed on amateur operators on the band due to this petition. From my limited knowledge of operating practice, I would assume transverter tuning limitations and repeater splits would be principal challenges.
