OpenGD77

The Feb 12th version v0.1.0 is locking up on both my Pi4B and PiZeroW. I'm returning to the prior firmware for testing. This looks like the old buffer overrun problem, with the dashboard on PiStar frozen on TX Both Raspberry Pis are generating quite a bit of heat during the failure (53.9 C on the Ze...

Is the project ready for this (I'd estimate a few months to write it and get someone to consider publishing it)?

Before I consider working on this, I want to gather the thoughts of the GD77 development team and project leadership. I would be interested in writing an article for publication about the GD77 project and the technology advances it incorporates. I'd like access to materials we've been sharing and di...

Thierry, thank you for maintaining this very useful overview.

It certainly helps understand the control options of OpenGD77 quickly.

I forgot about the "Cast" driver.... back to the configuration. Marc

I'm more impressed every day.

IIRC, at some point a week or two ago, the Hotspote mode started displaying the node's IP address while the radio was idle.

This is now blank with installation of version v0.1.0.

Is this a new setting, or has it been dropped accidentally?

Thanks, Marc

@kd2lh The FET's have no dedicated heat sink, they just rely on the copper in the PCB to conduct the heat into the chassis of the radio. I doubt you will hear anything from Radioddity. They don't actually manufacture the radio. Its just a re-branded TYT MD-760 with updated firmware. The MD-760 is s...

If the thermal dissipation is adequate, the MTTF is in the millions of hours at the power (voltage and current) levels we're using even fully under power. Then the question will be, what is the impact of the heat on adjacent components. Still have not heard anything back from Radioddity or their Chi...

Like all different implementations of technology, the different products will have advantages and disadvantages in different usage contexts. While the MMDVM HS-Hat based simplex and duplex hotspots make great units for home or within a moving vehicle, the GD-77 provides additional range and a higher...
