OpenGD77

Ian I've found the problems in the firmware loader, and we'll need to make some changes to resolve the problem. I already know how to fix it, but we need to work out the best way to fix it. Either way, it won't be long before we post a updated version which should work OK. Many thanks Roger it's mu...

Because I don't have an AMBE dongle, I'm going to develop a utility which uses the radio to encode the WAV to AME, but its taking many hours of work to write both the additional firmware code and the utility code, so I"m unlikely to have much to show for at least another week. I made a set of scrip...

You radio has an electronics hardware fault, probably in the DRM audio path. Try to get a refund and buy another radio Unfortunately, it has been more than a month since the purchase, I will not be able to return it. Is there an electrical (or block) circuit on the dm1801 (or gd77) ? I'll try to fi...

If I install the original software, the noise is also present, but less pronounced.

Ok

As a fallback the firmware loader can be run from the command line

But I will investigate both the standalone loader and also the loader in the CPS

Ian You mean in the firmware loader, the Radio Button selection. We originally could detect the radio but unforunately when we started to support the RD-5R it uses the same ID as the GD-77S, so we had to remove automatic identification. I guess we could change the radio buttons to a drop down menu, ...

i suggest change serial module to HID device, as serial don't work on darwin. BTW. I checked ages ago if it would be possible to build both HID for the codeplug upload and CDCACM for Hotspot mode, but the USB stack is too big to fit 2 different USB devices into the MCU ROM Also, composite USB devic...

What is you callsign?
