    1. Plenty of Chinese DMR which would be compatible with MotoTrbo, e.g. Hytera, just search Alibaba

  2. So many standards to choose from. All we need is more than one manufacturer to support one. Until then, it's good ol' analog for me, it just works.

  3. Well I got mine today. I was told its best to put a password in these digital radios. I programmed a 4 digit code in this zt-9908 and it made its own 6 digit code. Now I cant get pass the password screen when I turn it on.

  5. I found out there is a password issue with these radios. When putting in a password use 6 digits or you may get locked out. Resolution to lockout that you wont find in the manual is a reset. To reset hold the 1 key down then turn radio on. I'm new to this type of radio but so far im not pleased with the analog reception. It should be compatible with the kirisun since I believe it has 3 codecs to choose from. I'm sure all these over seas radios talk to each other. All functions can not be programmed via software. To test digital I'll be buying a Kirisun or a MYT DP-208 soon.

  6. As far as size goes, if you have a baofeng with standard battery and one with extended battery. This radio is in the middle as far as height. It's just a little bit thicker. Feels really good in the hand. Perfect size. I love the electro screen. Tired of that baofeng 3 color crap and toy flashlight. This radio looks nice and looks professional. I hope someone makes a yahoo group on this radio. Another good test for all these digital radios is to find out if a reset will fix a stunned or killed radio.

  7. By the way. Those guys selling this radio on ebay for 103 bucks are great. They are fast promt and polite and always will assist in any problem with anything they sell. (hence the password issue) It's a lil bit more than amazon but the help I received was well worth it. They broke their necks to get that password issue resolved for me.

  8. It usesw the same programming cable, mics etc. as the baofengs and kenwoods. So if you already have a baofeng cable your good to go.

  9. I just ordered ZT-9908 today so I can play around with them and understand how they work. I was reading Kenwood has come on board with DPMR.
