Ground-based VHF hand-held, mobile and fixed radio transmitters, receivers and transceivers for the VHF aeronautical mobile service using amplitude modulation; Part 1: Technical characteristics and methods of measurement

REN/ERM-JTFEA-008

Talni VHF ročni, mobilni in fiksni radijski oddajniki, sprejemniki in sprejemniki-oddajniki za VHF aeronavtično mobilno storitev, ki uporablja amplitudno modulacijo - 1. del: Tehnične karakteristike in merilne metode

Ta dokument navaja minimalne zahteva za delovanje radijskih oddajnikov, sprejemnikov in sprejemnikov oddajnikov pri talnih aeronavtičnih postajah, ki delujejo v pasu VHF (od 118 MHz do 136,975 MHz), dodeljenemu aeronavtični mobilni storitvi.
V razmerah, kjer so oddajniki in sprejemniki nameščeni v neposredni bližini, obstaja možnost motenj. V takih primerih so lahko potrebni zunanji filtri ali izolatorji kot del postavitve, da se doseže izolacija večje zmogljivosti od minimalne, kot je določeno tem dokumentu za premagovanje motenj. Ta dokument velja za sisteme DSB AM, z medkanalskimi razmiki 8,33 kHz ali 25 kHz, namenjenimi za analogni govor, in s talnimi postajami z razmikom med kanali 25 kHz, namenjenimi podatkovni komunikaciji ACARS.
OPOMBA: Preskusne metode in postopki v tem dokumentu so prav tako lahko uporabljeni za prikazovanje tehnične sprejemljivosti za radijske oddajnike, sprejemnike in sprejemnike-oddajnike na talnih aeronavtičnih postajah, ki delujejo z razmikom 25 kHz med kanali v razširjenih pasovih VHF (od 108 MHz do 117,975 MHz in od 137 MHz do 155,975 MHz). Področje uporabe tega dokumenta je omejeno na talne postaje ter talne mobilne in ročne radijske sprejemnike za uporabo na tleh.
