I'm a new to ham as well.
I have a Baofeng DM-1701 DMR radio and use a Boomerang Pro hotspot.
I did flash my radio with Opengd77 firmware.
DMR is fun and neat to use.
If you take your time and don't get frustrated. Programming the hotspot and radio is a day project.
With a fairly confusing learning curve.
First get to QRZ.com and make a call sign page.
Log into radiod.net and get your DMR id. It's free.
If you have a local repeater that has DMR and you can reach it. You won't need a hotspot.
But will be limited to groups you can join.
Have fun and enjoy. There is so many ways to make contacts. We live it great times.
