Pozele vorbesc de la sine....

Ce aparataj folositi? Cel de mai sus e vreun Sony, probabil (gen SA3ES)?... Iar celalalt?

[globaldj]

Tunerul pt Tropo: Onkyo Integra T4670, 2x110 KHz Murata - narrow + 4x150 KHz Murata - wide;
Tunerul pt RDS : Sony ST-S 590ES, 1x110 KHz Murata - narow + 3x150 KHz Murata - wide;

Cele doua tunere functioneaza atat separat cat si interconectate: semnalul MPX din Onkyo este citit de decodorul RDS din Sony ;

[zvartoshu]

Foare bine ales T4670 la dx, se apropie de lubek rcc45, testate in camp de mine. Sony se poate face sa mearga la dx insa trebuie vazuta care bobina nu este calibrata corect. RCC45 foloseste amplificator de antena integrat pe PCB urmat de un circuit acordat pe intrarea la antena dupa care imediat dupa fet cu 2 diode varicap, dupa care un TDA1574 si un demodulator sensibil cu tda4210.
Cat despre lantul de 110+110+150+150+150+150 cu amplificarile repetate si corectiile laterale varfului de 10,7 iti rezulta o separatie aproximativa de 100khz doar daca una dintre purtatori nu are deviatie mare.

Intr-adevar, buna remarca legata de deviatia purtatoarelor FM... niciunul din posturile de radio nu cred ca respecta deviatia standard.

Intentionez pe viitor sa fac un upgrade la respectivul lant filtrare in ideea de a folosi in modul narow 2x110 KHz + 2x110KHz, urmand ca in modul wide sa pastrez configuratia actuala de 4x150 Khz.

Ma gandeam chiar sa ma duc in extrem cu toate riscurile asociate (scaderea puternica a calitatii sunetului, problemele legate de aliniere, etc) folosind o configuratie de genul : 2x82 KHz + 2x82 KHz + 2x110 KHz +2x110KHz+2x150 KHz + 2x150 KHz. Din pacate inca am gasit insa acele 4 filtre Murata marcate cu 10.7 T ... (10.7 MHY se gasesc cu usurinta pe e-bay) . Schema de inlocuire a unui filtru cu doua puse in cascada fiind inspirata de aici :http://ham-radio.com/k6sti/ifamp.htm

[zvartoshu]

E de ajnuns un singur filtru de 80khz dupa unul de 110 urmat de altul de 110+ sirargul de 150khz. Problema va aparea la deviatiile mari ca vor incepe distorsiunile din cauza loudness-ului practicat in majoritatea statiilor din romania si de deschiderea semnalului rds abia dupa 34db.
