Re: Can't run MMDVM HS DUAL HAT in DUPLEX mode

You probably need to separate the Rx and Tx antennas by some distance, the Tx wideband noise level is probably high enough to affect the receiver so you either need a diplexer with good filtering and use a fairly wide frequency split or you need to move the antennas at least a metre apart with good ...

Re: Bookworm support

Thanks for the explanation Andy, I only wish that my skill set was sufficient to volunteer to help, however I am not at all knowledgeable enough. I don't want to poison the well.

Re: Can't run MMDVM HS DUAL HAT in DUPLEX mode

Good, although I would expect both Rx and Tx to have the same offset given there is one TCXO.

Re: Bookworm support

Working on it, but it's part of a much larger set of changes. If you have a chance Andy, it would be very interesting to know what it is about Bookworm that makes these larger set of changes necessary. The way current Pi-Star images are created, this has been a problem brewing since the first relea...

Re: Upgrade Pi Zero to Pi Zero 2

How difficult (or not difficult) is the upgrade? Does the PiZ 2 just plug in exactly where the PiZ 1 is? No soldering needed? If you order one with the header installed already then yes, otherwise you have to solder the 40 pin header in yourself. Once you have physically swapped over all that's nee...

Re: MMDVM Duplex Hotspot: Two modes?

DMR has 2 timeslots, but Fusion doesn't because it is 100% duty cycle on transmit. I can't see how you can mix them, but of course you can use the 2 DMR timeslots for different TGs.

Then use your current hotspot for Fusion.

Re: Pi-Star Brandmeister connection problems.

Any idea if your fibre connection has CGNAT involved? It might be down to some odd port re-routing going on where it's difficult to see it in action.

Re: End of support STM32F1* boards?

Are there any with the same form factor to fit over a Pi Zero 2W in the small cases?

So far I can't see any for sale.
