Turns out that the widely used preset for the US is not compliant with FCC regs. See https://github.com/meshcore-dev/MeshCore/issues/945

Changes that comply are being tested

• Freq 910.100 MHz
• BW 500KHz
• SF 10
• CR 8

These settings would comply and be the closest to the current bitrate we already have.

I have already opened issues for the two main open source apps

• Meshcore-open: https://github.com/zjs81/meshcore-open/issues/542
• Meshcore One: https://github.com/Avi0n/MeshCoreOne/issues/420

My suggestion to the app makers was have a preset called “(recommended)” with the new settings and another one called “(legacy)” with the current settings that could be removed in a few version updates. That would allow for a graceful transition period.

We as the community will also have to repeat this signal (pun intended) so that everybody knows they need to make a change
