C.D. Posted October 9, 2016 Share Posted October 9, 2016 (edited) Este centrat pe 75 MHz si are banda in 6 dB de +/- 10 KHz. (banda totala de 20 KHz) Se pot folosi doar la R1300 in mixerul cu prima schimbare de frecventa pe 75 MHz. (sau alte constructii radioamatoricesti) R1300 mai are inca 4 filtre pe 250KHz folosite in a doua schimbare de frecventa. Filtrul de CW (A1) este centrat pe 250 KHz si are banda de 500 Hz. Filtrele de SSB (H si L) cu banda fiecare de 3,4 KHz. Filtrul de F1 este centrat tot pe 250 KHz si are banda de 1KHz (era folosit pentru teleimprimator) Edited October 9, 2016 by cristiand02 Quote Link to comment Share on other sites More sharing options...
