PD782 to Hotspot

[dpjohnson13]

I am at a loss on this. I have multiple PD782s, Anytone, Radioddity, Maxon radios along with about 6 Pi-Star DMR hotspots. Im doing some testing. I have one PD782 that will not talk to any hotspots no matter the frequency. All the other radios will work with all the hotspots except one PD782. I am at a total loss. I can clone the radio to this one and it still doesn't work though it will talk normal radio to radio. I can put the radioddity in VDX mode and see the PD782 talking but the hotspot never receives from this one radio? I don't even see how it is possible as it will talk fine radio to radio but no hotspot. I have tried resetting the PD782 to factory defaults nothing I do will get this one particular radio to talk to any hotspot on any frequency. Is is something stupid im overlooking? All the firmwares on the radios are the same. Every conceivable setting is identical but this one radio will not work with a hotspot. Even tried putting the hotspot into public mode.

I think it is just a cheap pi-star issue

What is the Live Logs function in the Pi-Star software showing you when you compare successful transmissions from say, the AnyTone radios vs Hytera?

It doesn't show when I key the Hytera, when I key another radio I can see it TX

HI, just a thought. When I had my PD782 a few years ago, I had the same issue with my cheap Jumbospot not receiving transmissions from the Hytera. I had to play with the RX offset in Pi-Star under Configuration/Expert/MMDVMHost. I'm not sure what board you are running on top of the Raspberry-Pi but if it is one those Chinese boards then I would take a look at that. It may not be your issue but it's worth checking.

Thanks Ill try that. It actually works with a OpenGW77 radio Hotspot so im thinking it is the boards on these

you were right! They actually have a calibrator built into pi-star. ----- MMDVMCAL. works awesome
