05-01-2026 - ENTIRE WORLD DMR-ID CONTACT LIST OF 304598 RECORDS FOR THE RT-4D/KD1MU RADIOS - W1AEX

Monthly release of the RADIO-ID database for entry into the Address Book of the RT4D and KD1MU radios. 

The data is now displayed in this format:

LINE 1:  DMR-ID CONTACT NUMBER
LINE 2:  CALLSIGN || FIRST NAME
LINE 3:  STATE || COUNTRY

This release uses measures to best display the RADIO-ID, CALLSIGN, FIRST NAME, STATE/PROVINCE and COUNTRY of stations you receive while operating DMR. To allow all countries to fit into the RT4D/KD1MU flash memory space, the CITY and LAST NAME data have been removed and the number of characters in several database fields has been limited to the maximum possible for the RT-4D display. This assures the best display of information and removes unused data that cannot fit on the RT4D/KD1MU display lines. 

In addition, with only a few exceptions, country names are replaced with the conventional capitalized 2 or 3 letter abbreviations to assure a fit on display LINE 3. 

Note that there are many callsign records in the DMR-ID Contact Database that users have left incomplete or incorrectly formatted. This contact list will display whatever random name and location data has been entered but the station's DMR-ID and callsign will always be present in the display.
