Hi Folks For the most part the MMDVM suite of programs work well. The occasional problem surfaces, but mostly it just works. It's a good place to be. The lockdown in Spring last year allowed me to add FM and AX.25 to the modem based MMDVM and these seem to work pretty well too. There are still some outstanding areas that I would like to see finished, or even started! Most of them aren't really urgent, but getting them done would make the MMDVM even better, either from the usage point of view, or from the software maintenance side. So here is my list of things that it'd be great to have finished. They are in no particular order. 1. D-Star - Convert the ircDDB Gateway to use STL instead of wxWidgets to remove that dependency. Maybe restructure the configuration file to match the format used for the other gateways. 2. DMR - Add GPS gatewaying capability to the DMR Gateway. There are many different formats for this data, so it's quite a lot of work altogether, but each format would be worth having on its own. Known formats are: Motorola, Hytera, generic Chinese, Kenwood, and Tait. 3. System Fusion - Upgrade the DG-Id Gateway to handle IMRS and the radio confirmation bleeps. This requires network traces and data dumping, which should be possible post lockdown. 4. P25 - Understand how to handle the data modes over the network and gating GPS data to APRS-IS. 5. NXDN - Look at the Kenwood network protocol support again. It's not quite right, this also applied to the NXDN Reflector. 6. POCSAG - Nothing :-) 7. FM - Add an interface into at least one VOIP network. 8. AX,25 - Nothing :-) 9. M17 - Almost everything. Until there is a standard M17 transmission to work against, this is quite difficult. Most of the code exists, but is mainly untested. Once voice is working, GPS gatewaying to APRS-IS via the M17 Gateway needs to be added. So if you have some spare time, and you want to contribute, have a go at one of these. Jonathan G4KLX

Configuring audio levels for AX.25
