Clean, well-scoped change. A few observations:

Looks good:

• New fields in RadioInfo have sensible defaults (false / empty QString), so existing code that doesn't touch them is unaffected.
• Parsing follows the existing parseDiscoveryPacket pattern exactly — no new allocation, no new error paths.
• All three files are squarely within scope for the stated issue.
• No convention issues — no QSettings, no raw pointers to manage, consistent style with surrounding code.

One minor note on the ConnectionPanel display:

• turfRegion is appended to the detail line raw. If the radio sends something like turf_region=USA that's fine, but if it ever contains underscores or unexpected formatting (like the status field does), you may want to run it through normalizedStatus()-style cleanup. Not blocking — just something to keep in mind if users report odd-looking labels.

No issues found with null safety, resource leaks, or out-of-scope changes. isSystemModel is parsed and stored but not yet displayed in the UI, which is fine — it's available for future use and doesn't add dead code risk since it's just a struct field.

Thanks for the contribution, @aethersdr-agent — straightforward and correct. 👍
