Aplicatie Demonstrativa <50 MHz

Recommended Posts

Buna seara. As dori sa stiu daca exista vreo banda <50 MHz in care se pot face transmisii digitale (PSK, FSK) ~1W.

Am cautat prin http://www.ancom.org.ro/uploads/links_files/TNABF_2009+modif-2010_2011.pdf, dar nu inteleg mare lucru. Din cate am inteles CB-ul ar fi numai pt FM si AM audio, deci nu e o optiune. Mentionez ca nu sunt radioamator, deci as dori sa fie ceva legal. Vreau sa fac un experiment cu SDR pentru o aplicatie demonstrativa. Daca nu exista asa ceva, as dori sa stiu care este Pmax care se poate emite digital in CB fara sa suparam pe nimeni (sau in oricare banda < 50 MHz). Mentionez ca pt. demo am nevoie de o distanta mica <100m.

Va multumesc!

Multumesc de raspuns, dar cred ca am sa raman doar la receptie, transmisia am sa o fac cu ceva module TX in ISM, nu vreau sa am probleme. Din cate am inteles ar fi ceva probleme cu armonicele, etc. Oricum nu incorporasem un detector de putere pe partea de Rx asa ca puterea ar fi greu de controlat cu exactitate.
