Urmarirea balonului este cruciala pentru succesul zborului.

Componentele sistemului de receptie


receptor radio adecvat benzii si tipului de modulatie sau receptor SDR (RTL, Funcube Dongle, SDRplay, s.a.)
antena verticala pentru urmarirea in timpul zborului si antena directiva pentru recuperarea la sol
computer caruia sa ii furnizam stream-ul audio
interfata audio in cazul unui receptor radio clasic
softul de decodare DL-FLDIGI (https://ukhas.org.uk/projects:dl-fldigi)
internet


In cazul utilizarii unui SDR, este necesar si softul acestuia (SDR#, HDSDR, s.a.), precum si o modalitate software de a ruta stream-ul audio catre DL-FLDIGI (recomand Virtual Audio Cable (https://www.vb-audio.com/Cable/)).


Cele mai comune tipuri de emisiuni sunt 2m APRS (FM), 70cm RTTY (SSB) si HF WSPR/JT9 (SSB).


2m APRS

Baloanele cu transmisie in 2m APRS sunt, de regula, receptionate in mod automat de multitudinea de statii si sisteme automate de la sol.

70cm RTTY

Cele mai multe baloane transmit RTTY in 70cm SSB. Va trebui sa cunoastem frecventa si caracteristicile RTTY folosit : rata de bit, shift, format (exemplu : 434.5 MHz, RTTY 50baud, shift 400Hz, 7N1). Ghidul nu este nicidecum exhaustiv, existand baloane care folosesc si alte moduri, cum ar fi Contestia, dar pasii sunt aceiasi.

Deschidem DL-FLDIGI in modul HAB.

HF WSPR/JT9

Cele mai comune benzi sunt 30m si 20m. Frecventele WSPR si JT9 sunt bine definite:

WSPR
30m 10.140100 - 10.140300 MHz
20m 14.097000 - 14.097200 MHz

JT9
30m 10.14000 MHz
20m 14.07800 MHz

Exista o multitudine de receptoare automate pentru WSPR, distribuite pe tot globul. Totusi, sugerez ca urmarirea sa se faca si manual, in limita posibilitatilor. Pentru JT9 nu exista receptoare automate, deci se face exclusiv manual.

Avem nevoie de receptor clasic in HF sau SDR, cu mentiunea ca RTL-SDR nu coboara atat de jos in frecventa.

Decodarea se face cu binecunoscutul WSJT-X in mod WSPR, cu mentiunea obligatorie sa fie bifat Upload spots.

Spoturile sunt incarcate automat pe platforma http://wsprnet.org, de unde un coleg radioamator suedez le preia in mod automat cu un script pentru a le afisa pe harta.

De mentionat este faptul ca modul WSPR este foarte limitat ca si informatie transmisa, asa ca telemetria se codeaza separat, si se transmite tot via WSPR sub forma unui indicativ care poate incepe cu literere Q sau O. Totul este automat.

Protocolul special de telemetrie WSPR este disponibil aici (http://www.qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s4.html#protocol).
