I use firmware 0303 and although I think it worked with my Portsdown it may have "issues". It's certainly not supported...

I recall having to add a patch, and it may have been to enable the switching of the external reference. I have never used my Rev D Pluto with my Portsdown, so you'd be on your own if you tried it, but I doubt it can do anything dreadful. I'll link to the patch on my server so you can grab it and try it if you like?

Read the text file within the zip, it gives info on version compatibility. Personally I'd just patch your firmware and wing it .... ;) I am pretty sure it was needed to enable the external reference, now I cast my mind back, as I do not need or use the PTT stuff.

The interrogation stuff looks as if the external clock *SHOULD* be enabled, so it must be something else. It's all a bit of a minefield mixing and matching firmware with various hardware at times.

Good luck.
