The Retevis RT84 is the same hardware under a different badge and appears in qdmr as the alias key rt84; one entry covers both. Every limit here was read from qdmr v0.15.1 source, lib/dm1701_limits.cc (the DM1701Limits constructor), which is the exact table dmrconf verify enforces, so a profile that passes codeplugger validation is checked against the same numbers the writer will apply: channels 1-3000, zones 1-250, scan lists 0-250, group lists 1-250 with RadioLimitGroupCallRefList(1, 32) talkgroups each, and DMR contacts 1-10000. max_channels_per_zone is 64 because a zone on this family has two channel banks, A and B, each a RadioLimitRefList(0, 64) bound to one VFO; codeplugger models a zone as a single list, so 64 is the safe per-zone figure and a 128-channel zone would only fit by splitting across both banks. max_channels_per_scan_list is 31, from RadioLimitRefList(0, 31); this is a different and larger figure than the DM-32UV's 15, so do not carry DM-32UV scan-list habits over. max_dmr_ids is 1: the radioIDs list is DMRRadioID 1-1, a single radio ID, unlike the AnyTone radios that hold several. All four name fields are RadioLimitString(1, 16) Unicode. Band edges 136-174 and 400-480 MHz are declared identically for the rxFrequency and txFrequency limits of both FMChannel and DMRChannel, so the radio is dual-band for transmit across both ranges and can carry MURS and GMRS as well as the amateur bands. Note that the UHF ceiling here is 480 MHz, while the OpenGD77 limits used by the baofeng_dm1701_opengd77 entry stop at 470 MHz; the two files are deliberately different and must not be cross-copied. Bandwidths are the Narrow and Wide members of the FMChannel bandwidth enum. There is no AM mode and therefore no rx_only band. Several real capabilities of the radio have no schema field yet and are recorded here instead: a call-sign database of 122197 entries, DMR APRS positioning systems 0-16, color code 0-16, transmit power Low/Mid/High on DMR channels but only Low/High on FM channels, and both basic and AES encryption key slots. NOT BENCH-VERIFIED: as of 2026-10-08 no codeplug has been written to a physical DM-1701 through this path. These numbers are source-derived, not hardware-derived, and the site row carries no hw flag until a write and read-back diff passes on Eric's radio."

Program it with the dmrconf backend using radio key openuv380 (qdmr calls this OpenMDUV380); the OpenGD77 build for this hardware is the shared MDUV380/DM1701/RT3S/RT84 STM32 target, which is why this entry and retevis_rt3s_opengd77 carry identical limits. Those limits come from qdmr v0.15.1 lib/opengd77_limits.cc: 1024 channels, 68 zones of up to 80 channels, 76 RX group lists of 32 talkgroups, 1024 contacts, and 16-character names throughout. max_scan_lists is 0 on purpose and is not a placeholder: OpenGD77 has no scan-list object at all, it scans by zone, so any profile that defines scan lists must not be built for this entry. The UHF ceiling is 470 MHz rather than the 480 MHz the OEM firmware accepts, because OpenGD77Limits declares 400-470 and qdmr rejects anything above it on this key; do not raise it to match the OEM file. Capacities here are far smaller than OEM in every dimension that matters for a large codeplug, most sharply contacts at 1024 against 10000 and channels at 1024 against 3000, so flashing OpenGD77 onto a radio already carrying a full OEM codeplug is a capacity downgrade and the profile has to be rebuilt, not reused. Two dmrconf quirks apply on this key and are already handled in the backend: dmrconf verify --radio=openuv380 segfaults in 0.15.1 because cli/verify.cc constructs the radio without a device and the OpenUV380 constructor dereferences it, so the backend substitutes the opengd77 key for verification, which is equivalent because both share the one OpenGD77Limits singleton; and a device write auto-detects the model, so the wrapper never passes --radio when writing to hardware. NOT BENCH-VERIFIED: as of 2026-10-08 Eric's DM-1701 is still on OEM firmware and nothing has been written through this path, so the site row carries no hw flag. The plan is to prove the OEM path first, then flash OpenGD77 and re-test."
