TH-D72A/E - N3UJJ

2 HOW YOU ENJOY APRS WITH TH-D72A/E (WRITTEN BY BOB BRUNINGA, WB4APR)• Field Data EntryIn addition to making excellent field data display devices, the TH-D72A/E menus have also beendesigned for easy data, position and message entry. Often overlooked is the ability to useTH-D7A/E, TM-D700A/E, and TM-D710A/E as excellent field data entry and clipboard entrydevices at many field events.Refer to: http://aprs.org/aprsevent.html• Individual Information AccessThe Kenwood individual radio displays enhance the distribution of ham radio information to a largenumber of users by giving them individual front panel and keypad access to all of the online APRSdata. A common mistake of fixed operations with computers is the use of large display screens forlarge groups to see but which fails to recognize the individual needs of a given viewer. Theindividuality of APRS radios with individual displays spreads this data access throughout the usersin the field.• Overlay Characters on all SymbolsThe Kenwood TH-D72A/E has been expanded to show the overlay character of all symbols, notjust the original subset of special symbols. This provides hundreds of new symbol combinationsfor better APRS application to new uses.• DigipeatingNew TH-D72A/E is the first APRS HT to have a digipeater function. Each radio now has frontpanel access control to the digipeater function so that it can be turned on and off as needed tomatch the local situation. In addition, each TH-D72A/E can be used as a TEMPn-N digipeater insupport of emergency operations when a user is having difficulty accessing the existing WIDEn-Nnetwork. Refer to: http://aprs.org/TEMPn-N.html• Voice Operating FrequenciesThe most important new feature of the new TH-D72A/E is the recognition of the value of the voiceoperator frequency as a fundamental communications parameter. Not only does the radioautomatically include its own voice band frequency in every position packet, it also has specialdisplays and features that make this information readily available. For example, the station list canbe sorted to bring Frequency Objects to the top of the list in frequency order. Further, the radiocan tune to these frequencies for quick QSO with a single press of the TUNE menu.• EchoLink, IRLP or Winlink FrequenciesNew TH-D72A/E frequency TUNE function not only makes rapid QSY to another station operatoreasy, it also facilitates quick tuning to nearby EchoLink, IRLP or Winlink frequencies with the pushof a single button. Future use of this capability is anticipated to automatically and seamlesslyintegrate callsign to callsign calling from RF via local, national and global ham radio VoIP systems.Note: If all you think of when you hear the word APRS is maps and stagnant icons, then you are not using the full potential ofAPRS. If all of the local information that can be of immediate value to the APRS HT or mobile operator is not showing upin your local area, then get active and get involved in supplying this content. APRS is a communication tool, not just anautomated map. Use it. But in most cases, that means entering data, not just watching it. Kenwood has provided theAPRS handheld and mobile information display capability, it is up to us to provide content!14 CONTENTS TH-D72A/EFrom The N3UJJ.COM Document Library
