Sabah is now on APRS.....

wah.......rakan-rakan di Sabah betul-betul menunjukkan minat yang mendalam dalam APRS.Hasil keberkesanan racun yang digunakan oleh 9W2PD dan 9M2AUR telah menampakkan hasil yang begitu membanggakan...tahniah untuk rakan-rakan disana...seperti 9W6BOY,9M6DJC, 9W6HLM,9W6MAN,9W6DEN,9W6MRS dan 9W6IWN serta 9W6FTT.

Semoga anda semua beroleh pengalaman yang baru dan boleh digunakan apabila keadaan memerlukan. Ini adalah sebahagian daripada track yang dihasilkan oleh mereka..tahniah semua!

hidupkan APRS dikawasan anda...

how fast can you go?


dapat dari forum 100watts...menggunakan pesawat terbang..tengok speed...he..he
siapa mahu cuba?

my PUXING PX777..buat hal

Setelah hampir 2 tahun berkhidmat,akhirnya handy pertama aku buat hal...Mungkin masa buat programming untuk interfac APRS tempoh hari,telah menjejaskan settingnya.
Tak dapat masuk VFO,tak dapat Reset.Dah jadi macam set Mototrola.

...he..he.buat sampai tension,cabut jack,pasang jack,tanpa 'off'kan radio dan tengah running 'script' di COM port.. adei..- moral..off radio dulu lain kali-

Dengan berbekalkan komputer dan 'google' carian di internet dimulakan dan hasilnya amat menarik,radio ini boleh diprogram menggunakan komputer(tak payah susah-susah pulas tombol dan tekan keypad)...hmmm menarik tu,kenapa la dia tak jadi awal-awal dulu..kan senang..

Ok untuk memulakan projek ini,bahan-bahan yang diperlukan ialah interface,PC (ada COM Port) dan masa..hu..hu..

interface tengah beroperasi


program yang boleh didownload dan mudah digunakan

ok..berjaya mengembalikan setting asal,tiada channel yang hilang..dan siap boleh tulis nama kat dalam radio ni lagi..he..he..bagus ni

..tu je la 73

Q Construct.. for APRS

The "q-construct" is implemented on APRS-IS to add the following capabilities to the Internet APRS transport mechanism.

APRS-IS Entry Identification
Support for a Future Authorization Algorithm
Support for Loop Detection
Support for Automatic Loop Protection
Compatibility with Existing IGate and Client Software
Only Server Support Needed for Implementation
The currently defined q constructs are:

Server Generated:

qAC - Packet was received from the client directly via a verified connection (FROMCALL=login). ; The callSSID following the qAC is the login of the client.
qAX - Packet was received from the client directly via a unverified connection (FROMCALL=login). ; The callSSID following the qAX is the login of the client. ; This construct is in addition to the TCPIP*/TCPXX* construct currently in place.
qAU - Packet was received from the client directly via a UDP connection. ; The callSSID following the qAU is the login of the server.
qAo - (letter O) Packet was received via a client-only port, the FROMCALL does not match the login, and the packet contains either a ,I or qAR construct where the indicated IGate matches the login.
qAO - (letter O) Packet was received via a client-only port and the FROMCALL does not match the login.
qAS - Packet was received from another server or generated by this server. ; The latter case would be for a beacon generated by the server. ; Due to the virtual nature of APRS-IS, use of beacon packets by servers is strongly discouraged. ; The callSSID following the qAS is the login or IP address of the first identifiable server (see algorithm).
qAr - Packet was received indirectly (via an intermediate server) from an IGate using the ,I construct. ; The callSSID following the qAr it the callSSID of the IGate.
qAR - Packet was received directly (via a verified connection) from an IGate using the ,I construct. ; The callSSID following the qAR it the callSSID of the IGate.
Client Generated:

qAR - Packet is placed on APRS-IS by an IGate from RF. ; The callSSID following the qAR it the callSSID of the IGate.
qAZ - Packet is generated by the server/client/IGate and should not be propagated. ; The callSSID following the qAZ is the callSSID of the server/client/IGate. ; This is normally used for connection messages such as messages to USERLIST.
qAI - Trace packet. ; This packet tells each server to add login identification to the packet. ; This packet starts with the callSSID of the originating station following the qAI. ; See algorithm for more details.
Client generated q constructs will be verified if a new authorization algorithm is created.

Servers MUST have unique logins from any other server/IGate/client that insert data onto APRS-IS. ; This is to prevent packets from being erroneously detected as looping. ; For instance, if my server's login is AE5PL and my weather client is AE5PL, my server will see ,qAC,AE5PL and consider this packet a looped packet. ; As logins can be any combination of 9 alphanumeric characters, this should not pose a problem.

IGates which append IGATECALL,I to the end of packets and which are directly connected to a server which supports the q construct will have the IGATECALL,I converted to qAR,IGATECALL, qAr,IGATECALL, or qAo,IGATECALL to support the extended capabilities of the q construct.

Servers will have the ability to selectively enable tracing on all packets through server configuration. ; This must be used judiciously and only when a loop condition is suspected due to the increased bandwidth demands that tracing creates.

q constructs will only appear on APRS-IS and are not to be used elsewhere due to bandwidth considerations.

For example, this is what happens to a packet without a q construct which enters the system via a verified connection:

Original packet:
AE5PL>APRS,TCPIP*:payload

Packet leaving the server if trace is off:
AE5PL>APRS,TCPIP*,qAC,AE5PL:payload

or, if trace is on:
AE5PL>APRS,TCPIP*,qAC,AE5PL,AE5PL-JS:payload
