You need to work out the link budgets for Tx and Rx, assume 0dB isolation between the antennas and use the ADF7021 phase noise plots to estimate the energy from the Tx at the Rx frequency. You also need to consider the blocking performance of the Rx against the Tx signal at +13dBm or similar. Full d...

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 ...

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.

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

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...

Which modem do you have selected in the configuration page?

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...

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.

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.
