Detailed Description
Represents and encodes the binary format for the call-sign database within the radio.
The memory layout of the call-sign DB is relatively simple. The DB starts at address 0x00030000 with a maximum size of 0x00040000. The first 12bytes form the DB header (see OpenGD77CallsignDB::userdb_t) followed by the DB entries (see OpenGD77CallsignDB::userdb_entry_t).
The entries can be of variable size. The size of each entry is encoded in the header. QDMR uses a fixed size of 19bytes per entry. The entries must be sorted in ascending order to allow for an efficient binary search. No index table is used here.
