Nova ATV oprema na Učki

9A0TVR repetitor od sada ima stalni ATV prijamni link prema talijanskom ATV repetitoru IR3UDC koji emitira na 10,470 GHz. Antena prijamnog linka je 70 cm prime dish, koja je spojena na posebni satelitski prijamnik. DTMF naredbom 5 na frekvenciji 144,740 MHz omogućuje reemitiranje talijanskog ATV repetitora IR3UDC preko 9A0TVR.

Prijemna oprema na 9A0TVR uključuje 2 prijamna linka, prvi prema ATV repetitoru IR3UFV (Mt. Crostis) i drugi prema IR3UDC (Bassano del Grappa). Sa ta dva prijamna linka proširen je domet ATV repetitora 9A0TVR na Učki. Od sada se na ATV repetitoru mogu vidjeti dio Slovenije, područje Venecije, Riminija. Frekvencija od 144,750 MHz služi za DTMF upravljanje ali također i za glasovnu komunikaciju. Ta frekvencija se reemitira na 6,50 MHz subtone frekvenciji na 10,410 GHz.
S DTMF naredbom 4 prebacujete 13 cm prijemnik ATV repetitora 9A0TVR u funkciju koji služi kao ulaz u repetitor. Frekvencije za ulaz na ATV repetitor mogu se mjenjati DTMF naredbom 3. Kanali su sljedeći:
