Starting a thread on this since I hijacked Midland's thread talking trash :censored:

506212

Key Points:
  • Chinese Radios, not FCC Approved
  • Programmable w/Chirp for GMRS Bandplan
  • Supports Duplex Programming (Supports Repeaters)
  • USB Field Charging
  • No Display, Rugged, Simple
  • Lightweight and Small
  • Cheap - $16 shipped each
  • Multi-Gang Charger Available
Flaws:
  • RX Tones dont seem to work, it will TX tones but is wide open on RX..
  • Power Cycling radios unlocks em if you lock buttons (hold ch down)
  • Chirp Files Might need to be hacked to talk to Zastones since its looking for a Retevis model reply.
  • FCC Might Block import/sale of these at any moment.
  • PROGRAMMING IS REQUIRED
  • GMRS LICENSE IS REQUIRED
I used these all last season w/and without my repeater online, range and audio quality were on par for specs/price.. Many kids played with em and they all came back in good working order despite the typical bike crashes and other abuse kids dish out.

If my changes to the radio spec files have not made it into the latest release of Chirp I'll dig my changes out and post em here.. Currently I got em on a RPi that I used for programming these and its not online ATM or I'd just do it already.. hopefully Chirp merged my changes into a later release and it works OTB right now.

The 6 Gang Charger operates off 5v, I got a 12v to 5v 5A Buck Converter, soldered on a 2.1 x 5.5mm barrel plug and wired it directly into my 12VDC system behind a switch.

Let the discussion commence..

problem? nothing really.. I just mentioned these in passing in another thread for another radio started by a forum sponsor and kinda derailed the entire discussion towards these.. so I decided to give it a legit review and its own post just to be nice to poor Midland.

I would like to take this moment to also apologize for my contribution the the thread-derailment of a sponsor.

Any step by step tips for programming these? I've tried multiple cords, multiple computers, multiple programs (CHIRP and the Retevis software), and I just can't get these to initially connect. Would like to know more about your programming setup so I can replicate it. They came programmed to GMRS but they are toned out, so I've taken to programming special channels on my baofeng just to communicate with these.

I would like to pick up a set of these for traveling but also for emergency management jobs. I do contract work for various govt agencies when there are national disasters and getting comms set up is always an issue. I have my HAM license but most don't as they are part of law enforcement / fire and have various radios. I'd like to use something like this to get everyone on the same page. But I am curious about the programming. If I buy more than one set, do I need to program them to all? Also, if some others have their own radios, how do I sort out if they are compatible?
