Live RF data on an interactive [Live RF Feed via VU2NCT on 144.800 MHz] This page demonstrates the ham radio capability in penetrating the Internet to serve useful purposes. This is a live APRS data feed page. APRS® stands for Automatic Position Reporting System. But this is not to be mistaken just as a mere automatic vehicle tracking system. It is real-time two way digital radio communication where many of the vital information are exchanged almost automatically. Non-hams can monitor ham radio APRS digital communication using this page. To just get a feel of how APRS activity is going on at other parts of the world here are a few links: | AE5PL | | WA4DSY | | SV1CNS | | HB9PVI | Radio & Beyond! On the New Delhi map displayed below, we can see hams doing APRS® communication [If they wish they may talk or otherwise exchange APRS digital data using their radios]. If they transmit APRS digital data on 144.800 MHz [which is VU2NCT APRS frequency], an APRS ready radio [Kenwood TH D7 AG] hooked to the Internet at VU2NCT can pick up the radio signal and in-turn feed the data to the Internet. During this demo, in a simulated exercise, the mobile station VU2MUE-9 [In most probability this may be during a demonstration. So if you don't see VU2MUE-9 on the map please feel free to contact him] appears on the map from RF originated data. There may be position reporting from Non-RF originated stations also. The station WB4TLP appearing with a WX icon is a ham weather station feeding weather data to Internet and these data are also available on the map for utility. How to use the map?

Why
javAPRS? During the demo, VU2MUE [SSID VU2MUE-9 Secondary Station IDentification for land mobiles] feeds the real-time RF [Radio Frequency] data via a KENWOOD radio interfaced to a computer at VU2NCT and that data reaches you via the Internet showing his positions & messages on a map. [a mobile station can in fact be tracked if the Internet map is monitored dedicatedly]. VU2NCT logs on to Rin Fukuda's (JG1VGX) Tier 2 T2JAPAN APRS server using Late Roger Barker's (G4IDE) UI-VIEW and then the data is internationally distributed from T2JAPAN tier 2 server. Mobile ham stations can remotely text message or send e-mail via the VU2NCT IGate even without a direct Internet connectivity. RF originated text message or e-mail can be read using this page.
UI-VIEW by Roger Barker, G4IDE Roger Barker's [G4IDE] UI-VIEW is a popular Windows based APRS application used by hams [radio amateurs licensed by the government] all over the world. UI-VIEW requires a validation from APRS server administrators. Being hams we always appreciate others also to become hams so that they can also use a beautiful software like UI-VIEW and enjoy the benefits of APRS Technology. There are many APRS applications now available for free. After downloading UI-VIEW, hams in Asia region can contact Art Takashi, JA1OGS for APRS Server validation. Art Takashi, JA1OGS is the official Registrar of APRS for Region-3 Asian countries. Why this map? The map below demonstrates the utility of an Interactive Internet map. This APRS map is accessible to hams as well as non hams too. Text messages originated from RF stations can be monitored by non-hams. This has utility in ham radio emergency communication [press 'M' and the read message at JAVA Console]
