Alasan Mengapa Lebar Pita Lebih 3KHz di SSB 40m Merugikan

[@DedyBlackLaBeneamata]

benar om, saat kontes kadang2 frekuensi penuh sekali padahal jaraknya lumayan tp masih terganggu

[@YD1DYZ]

kalau mau eksperimen lebih dari 3khz, connect ke dummy load, dengar sendiri pakai headphone di receiver yg berbeda. icom ic7300 sendiri teorinya hanya tx dgn bandwidth 2,8khz, tidak sampai 3khz. low cut 100hz, high cut 2900hz.

[@mahesajenar524]

Maksudnya nada di bawah 100 Hz dan di atas 2900 Hz akan diredam/dihilangkan gitu ya Pak ?

[@YD1DYZ]

@@mahesajenar524 teorinya begitu, fungsi dspnya utk itu, walaupun pada prakteknya masih ada yg lolos sedikit, tergantung setting levelnya

Radio HF dengan ditambahi perangkat HiFi ESSB audio.

[@panjikoming2407]

Setuju Oom, hf ssb harusnya bandwithnya sudah dibatasi, umumnya 2.4 khz. Fungsinya untuk komunikasi mode phone, yg penting pesan tersampaikan dan dimengerti, readible. Bukan untuk radio siaran musik yg nada rendah sampai tinggi harus. terdengar semua 😃

Betul om.. 😊

Kapan an boxing radio baru dibeli di japan

[@ye3eks]

Siap.. video nya sedang dipersiapkan.. 👍😊

I dont understand why they want to transmit more than 2.4khz. Definitely it create splatter to other station. I saw splatter more than 5khz. Even dx station doesnt like this. Its very disturbance. It also affected dx station nearby from Ja, VK, Du, Msia.

I completely agree with you, unfortunately several amateur radio insist for the transmitter to produce low audio more than typical by expanding the bandwidth.

[@9w8zzkmohamad59]

@@ye3eks totally true. Our radio transceiver was built in 2.00khz-2.8khz bandwith. Definitely we follow the ITU rules & regulations. Even dx stations doesnt like the splatter. I know the station wants the widen the bandwith to get broadcast audio (dum dum). There are ways to do that. Use 2.0-2.4khz its good enough. I dont understand why they wants it to be widen bandwith. Too much low audio, i dont even understand what they saying. Mid-high are much better.
