If I have KN4AQ and KN4AQ^^A both registered (which I do, with ^ meaning the space character), are they treated totally separately? Yes. John is correct; all 8 characters are used for the routing. A better term than call sign routing might be station routing. The D-STAR spec defines the first 7 characters as the callsign and the 8th character as the station ID. All 8 characters are used for station to station routing. Hope this helps. 73, Pete AE5PL
[DSTAR_DIGITAL] Re: Multiple 2820s / one callsign question
Per my prior post: the 8th character is considered an ID character. Within the current confines of the Icom gateway software, that character can be a space or A through Z. Program each radio with an unique ID character and you are good to go. If you intend to use a gateway, be sure to log into your registration page and register each ID you select. Hope this helps. 73, Pete AE5PL --- In dstar_digital@yahoogroups.com, Steve Lewis n8...@... wrote: Which is what I was afraid of. How have other users worked around this?
[DSTAR_DIGITAL] Re: DPRS issue
The issue is the symbol (or actually the lack of a symbol). The APRS packet format !3912.21N08421.72W/ should actually be !3912.21N/08421.72Ws where 's' is a character denoting the symbol used for your station. The symbol is a setable value in the 2820, consists of 2 characters, usually '/' (between the latitude and longitude) and another character denoting what symbol to use. If you manually set this up (I am not fully familiar with the 2820 programming) to something other than one of the 2820's predefined symbols, I am guessing that you tried to use a space or something else that is not allowed and the 2820 choked on it. Try using one of the predefined symbols in the 2820 and that should take care of it. 73, Pete AE5PL --- In dstar_digital@yahoogroups.com, Steve Lewis n8...@... wrote: Although I won't do it on a permanent basis, I want to be able to broadcast my location via DPRS.

[DSTAR_DIGITAL] Re: DPRS issue
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 dstar_digital@yahoogroups.com, J.Gordon Beattie, Jr., W2TTT w2...@... wrote: What do RMC and GCA mean?

Check out http://www.aprs-is.net/dprs.aspx for information on how to configure your radio to show up on APRS. D-STAR DV (D-PRS) and AX.25 (APRS on RF) are two completely different protocols so transmitting D-STAR on 144.39 will not get you seen on APRS. You must either use a D-STAR repeater or a frequency that has a D-STAR D-PRS IGate listening. 73, Pete AE5PL

It is sending out it's location just fine. However, the user there, KB1AEV is sending his location info from his 92AD with GPS mic and his location is not showing up. We tested this with the equipment here in CT and it all worked fine. He has not changed anything. The question is, what sends the DPRS info to the internet when a hotspot is involved. I see his GPS data on my DVtool screen and it looks correct. His D-PRS Interface will be the application to send the positions to APRS-IS. To do this, he must have the server passcode entered in D-PRS Interface and an APRS-IS server and port set into the configuration. He can contact me at pete at ae5pl dot net to receive his passcode if he has not done so already. The 92AD must be programmed per the instructions at http://www.aprs-is.net/dprs.aspx for the position reports to show up on APRS-IS and the GPS must have a position lock. Be advised that connecting a GPS mic to the 92AD causes it to default to a beacon every 5 seconds and should be reset to a much longer interval (or not at all for normal D-STAR usage). The radio will send position reports everytime he transmits voice. Hope this helps. 73, Pete AE5PL
[DSTAR_DIGITAL] Re: HOTSPOT and DPRS?
D-PRS Interface lets you look at the serial stream directly (without interpretation) by selecting Direct under View in the main menu. If Direct is not selected, it only shows you what passes CRC or FCS per the D-PRS specification. If it is not connecting properly to the hot spot serial TCP port, that should show in the Error Log (under Tools in the main menu). 73, Pete AE5PL --- In dstar_digital@yahoogroups.com, Francis Miele f...@... wrote: Thanks Pete.
