Go to http://www.aprs-is.net/dprs.aspx for information on the D-PRS translation and how to configure your radio.
As far as GPS-A vs. GPS modes, the D-STAR radios are not designed as interactive tracking radios. Some radios will show a transmitting station's position information if the transmitting station is in GPS mode. However, there is no memory and little error control. GPS-A mode is not displayed on remote D-STAR radio displays but is much more reliable due to the use of a CRC to error check the received data and due to the transmission of a single line instead of a group of lines. This is very important considering that the portion of the DV bit stream that is used for the GPS information has no error protection and is very susceptible to bit errors (the bit stream is a 4800 bps transmission). If your intent is to be seen in the APRS world via D-PRS, then GPS-A mode is the more reliable. If your intent is to have some other D-STAR users see your position on their display while you transmit, the GPS mode is the way to go. GPS mode if properly configured (see link above) will get you into APRS as well; just not as reliably. Use what fits your intended goals. Hope this helps. 73, Pete AE5PL --- In [email protected], "J.Gordon Beattie, Jr., W2TTT" <w2...@...> wrote: > > What do RMC and GCA mean?
