Here is my current lineup of DMR portables, arranged in descending order of physical size.
Left to right, the units are:
- Motorola XPR7550 UHF
- Ailunce HD1 U/V
- TYT MD-2017 U/V
- Radioddity GD7 U/V
- Retevis MD380 VHF
- AnyTone AT D868UV U/V
Of them all, in my personal opinion the AnyTone beats all of the rest in terms of functionality, features, memory expansion and battery life. It has all of the best functions and features of the MD380 with the "experimental firmware" but with both UHF and VHF and best of all, the smallest physical size! With the push of a single button the radio will receive any programmed TG in one or both timeslots. The CPS will export/import separate CSV files for Channels, Group and Private contacts, TGs, and all other sub-menu items making updating of these lists easy and fast!
Best of all, it is
fully front panel programmable!
My second favorite is the Ailunce HD1, but it has a few quirks that make it less enjoyable to operate. It has none of the functions or features of the Ailunce HD1.
My least favorite is the TYT MD2017. That stupid trackball is a massive PITA and makes it difficult to navigate zones, bands and menus.
While I do like the Motorola XPR7550, being limited to UHF only makes it no more useful than the MD380 VHF mono-bander. I had an MD380 UHF for about a year, but I sold it to a friend who needed an inexpensive UH HT.
