FINALLY! It shouldn't surprise anyone that TYT was the first to respond to Amateur Operators worldwide who have been wanting a dual band DMR Radio. With the success of the MD380, it is a no-brainer to create such a model. And here it is - after being heavy into DMR for about 4 years myself, this is the first dual band radio I've seen. Take a look at the review.
I received a (test) sample of the TYT-MD-2017 on Monday. It is still not available for sale to the public due to issues that are presently being corrected by the manufacturer:
1) Inability to lower volume on the analog frequencies ( 2 meters as well as 440 Mhz.) completely.. It cannot be muted when the volume control is completely turned-down. The audio on DMR (both 2meters and 440 MHz.), however, can be muted
2) Once a frequency in a zone (either in A or B) is activated, you cannot switch to the other (either in A or B) nor be able to move to another zone unless transmission stops
