DVmega or ZUMspot hotspot GMRS capability?

[WRZK971]

Anybody know if a DVmega Pi3 or ZUMspot elite 3.5 can be programmed to connect to GMRS live?

Thanks, Rick

Not sure if that is possible. I haven't seen any network talkgroup ids that are linked. Plus it's not in the same service, so what are the legal ramifications?

Would this be a violation (maybe multi violation)? I mean cross repeating two separate radio services? You know gmrs radio transmissions to an ip network over to an amateur ip network, then over to potentially retransmitted to amateur frequencies on a hotspot?

God my head hurts thinking about it.

Both of those hotspots are designed to join to a pre-existing network. For DMR that’s the Brandmeister network. There are also networks for YSF, DStar, NXDN, and P25. 
All of those are networks designed around digital voice modes. The hotspots expect to receive and transmit digital data, not analog FM. My hotspot wouldn’t know what to do with analog FM.
Currently GMRS is analog FM.

As an add on question to the OP's question, isn't the the DVmega and ZUMSpot just hardware that does what the OS tells it to and connects to the network programmed on the sd card? Could you write an image for the sd card to connect to the mygmrs network and have the hardware operate in FM, assuming it's FM capable?

I don’t know if the chipsets used in those hotspots support analog and I don’t know if the RF stage can be adapted to GMRS frequencies.  If they do, then possibly it could be done.

That's what I was thinking.  My fully legal hytera radios transmitting DMR would get converted to VOIP in the raspberryPI.  Brandmeister would have no play in it.  All the DMR would be local to my network, but forwarded to the network as voip, though the liveGMRS network.    If that's not legal, I'll just save up for a while and get a hotSpotRadio.

DMR is emission type FXE for voice and FXD for data, but the FCC constrains GMRS to the following:
 

95.1771 GMRS emission types.

Each GMRS transmitter type must be designed to satisfy the emission capability rules in this section. Operation of GMRS stations must also be in compliance with these rules.

(a) Each GMRS transmitter type must have the capability to transmit F3E or G3E emissions.

(b) Only emission types A1D, F1D, G1D, H1D, J1D, R1D, A3E, F3E, G3E, H3E, J3E, R3E, F2D, and G2D are authorized for use in the GMRS. Equipment for which certification is sought under this subpart may have capabilities to transmit other emission types intended for use in other services, provided that these emission types can be deactivated when the equipment is used in the GMRS.
