Hello, new user here from Arizona. I belong to a scanner group (APSN.US) and we use Zello to communicate with our group for Fire/EMS and PD incidents in the area. I just purchased a bluetooth handheld Mic HYS model HB980 and it works rather well. Its made in China by Baofeng and not finding a lot of information on it, like many Baofeng products the user manual leaves a bit to be desired. I was able to get it paired to my phone easily enough, but there is a programmable button near the PTT button, but no clue what it can be programmed to do or how to program it. Anyone else have one of these, pretty cool little device for using Zello.
