APDW17
¿ªÔÆÌåÓý
In APRS, because it uses multicast transmissions of AX.25 protocol packets to all nearby stations rather than addressed point-to-point packets, the AX.25 destination field is not used as a station address. Instead, it is usually filled in with a code identifying
the station equipment (software or hardware) being used to generate the packets. APDW17 is the APRS code for DireWolf release 1.7.
Is there any particular reason why you want to modify it? It's generally considered good practice in APRS to provide a useful "tocall" value, as it helps other radio users identify what is in use near them, in case they are looking for an Elmer and want to
know what is commonly used in their area.

Hello,
I am new? to APRS and I use Direwolf installed on Raspberry. At the start of the frames sent by my digipeater figure "APDW17". What does it mean ? Is Direwolf sending it ? If so, how to modify it ? Thank you. |

Further to Andrew's reply, if you like to see a list of tocalls to see how the various versions of hardware/software TNC are represented, it is available on the aprs.org website
And if really feel like tinkering with the tocall in Direwolf, then I suppose search the source code for APDW17 and replacing it with something of your choice & recompiling would probably do it, although generally it would have to start with AP at least, otherwise a lot of other TNCs will likely just ignore any packets, as they won't consider it to be an APRS packet. In general, its probably best just to leave it at APDW17 -Ian ZL1VFO |
