Would you consider creating a video that outlines your complete setup.
I dont have the proper equipment to do a video, but I can take pictures, and I am absolutely willing to help you troubleshoot.

Thanks so much⌠pictures and a detailed rundown would be very helpful. What do I need to make this happen?
Much of it depends on your radio and its specific settings. I dont have any experience with your particular radio. But if its motorola based for the mic. pin out. Then you may be able to use motorola connections for your phone.
Troubleshooting update. I have two samsung note 9 phones, that are running slightly different firmware. (Different cell service providers) one works perfectly and the other does not. This is even after I fashed the firmware to force the update. Phones work perfectly otherwise. They both tx, its just the one that wont recognize the incoming signal.
i have a phone that does the same thing
using ft8cn, you can see the incoming signal on the spectrum display.
you can raise/lower the âwaterfallâ color temp by raising/lowering the output volume of the radio.
the phone just never decodes any of the traffic.
(setup works fine on other devices)
weird. maybe audio phase twist (in the phone)?

Yeah, ive never been able to figure it out.
After years of messing with all this, this is my conclusion: At the end of the day, there is no good way to make all this work with reliability using inexpensive hardware. There are just too many problems that hacks donât address.
IF
- your radios could reliably connect to the EUD
- Your interconnects were locking, not unthreaded 3.5 phone connections and standard USBs
- The radio and interface were at least water resistant to IP65
- your encryption protocol was reasonably secure (I.e. true AES256 loaded from a keyloader)
youâd still be moderately hosed because your EUD is likely a device with cellular connectivity, so itâs about as secure as a Lake Barrington high school girl in a broken down car at midnight in Cabrini Green.
It winds up being a lot of work for something that works but can fail without warning by a phone plug being inadvertently pulled loose, or a sudden rainstorm getting into a non-water resistant project box. And thatâs not even considering the fact that ATAK yammers away to several USG servers any time it has a chance.
Itâs frustrating to admit, but itâs a toy at best. Like dressing up a Crosman M4 with a Chinese knockoff Aimpoint and a fake MAWL.
What does work: Persistent Systems: Wave RelayÂŽ, Mobile Ad-Hoc Networking Solution MANET, Wireless Secure Scalable Communication
Yeah, the MPU5 is a super nice system, the first clue about how nice it is, is the fact that no one, anywhere will tell you how much they cost. Its all âcontact us for a quoteâ. They are not meant for us lowely peons. A downside though is the frequency they use means you almost have to have several of them in a mesh network. You can do a lot with the computer to dig a weak signal out of the noise, but 1.5GHz doesnt travel well through obstacles or brush. I have a bunch of the little LoRa radios that I was playing with too. Even 900MHz (granted MUCH less power) struggles.
Theyâre multi band. And you need to have multiple units or the mesh function doesnât work (obvs). Iâve used them at work, they are NICE. You can buy them, they start at about 5500 and get to 10k each very quicklyâŚbut there arenât many other radios out there that can do what they do.
Iâve been spoiled by things that work well, and it can suck.
Ok I discovered something today while playing around. I always thought the sample rate should be kept low to make the signal easier to catch. I hade it at 10000 - 12000. I was wrong. Take the sample rate and push it up to 16000. All of my failure to copy array errors went away. Then it was just a matter of tuning the mic. gain, vox level, and phone, and radio volume. Again, start low and work your way up. Even the oddball phone that I couldnt get to work works now.
