Question and explanation?

[memo124]

Why is there different Emissions Designators for one frequency? So which one is it? Do I have to program each emission to find the correct one? NXDN, DMR and Analog.

They are covering all possible emissions just in case. You’ll have to monitor to see which one they chose to use.

I'm not an expert in licensing. However, I imagine that in many cases they are in the process of converting from analog to digital systems, so they'll have both to cover everything. In some cases, digital systems might fail back to analog or still need to have access to analog, or maybe another mode that is different than normal.

It depends. People license multiple modes for different reasons.
Some people license all the modes that their equipment is capable of operating on.
Some people license digital modes for future use.
Depending on your scanner or equipment it should automatically display any non-encrypted digital modes.

Just wondering. Thank you.

I never really understood why an emission designation needed to be specified. As long as I am within my spectral mask, who cares if i am utilizing NXDN, DMR or anything else for that matter. And dont get me started on having to have one for voice and another one for data. The entire thing is data in a digital radio system even if there are voice frames embedded.

Sometimes I think the FCC makes things more complicated then they need to be.
