Callsign and DMR ID are read from/written to the radio. Radio Name is saved in the JSON codeplug only — it is not yet wired to a radio memory location, so Read/Write won't touch it. Boot text and band limits moved to Radio Tools.

A separate, much bigger read-only table -- up to hundreds of thousands of entries -- that the radio checks to show a name on incoming calls. Not the same as the Contacts list above (that's capped at 1024 and selectable per channel; this isn't selectable, it's a lookup). Load a bulk snapshot below, then write it straight to the radio's own flash region.

When off, the radio shows its boot image/logo instead of these lines. Read from/written to the radio along with the rest of the codeplug.
Whole-MHz values only. Setting these outside your radio's real hardware range won't extend it -- and setting them wrong can prevent the radio from transmitting/receiving at all until corrected. Check your radio's documented range first.
Saves the exact bytes currently on the radio -- everything this app reads/writes, including channels, contacts, zones, and satellites -- to a file, unprocessed. This is a stronger safety net than Save JSON: it preserves fields this app doesn't understand yet too, since nothing is decoded or re-encoded.
Writes a previously saved backup's exact bytes back to the radio, overwriting the entire codeplug. Refuses automatically if the backup was taken from a different radio family (MK22 vs STM32) than the one currently connected.
"CPSd" is half backronym ("CPS Dashboard"), half wink at Unix daemon naming (httpd, sshd...) since this thing runs as a small self-hosted service you keep running in the background. "ReallyOpen" is a friendly jab at grid.radio/opengd77, a nice web CPS that -- despite the name "OpenGD77" -- isn't actually open source. (In fairness, even the real OpenGD77 firmware isn't 100% open end-to-end, thanks to the usual firmware licensing/patent realities of ham gear. We can only promise to be "really open" where it counts: this codebase, right here.)
