Icom IC-M803

MF/HF MARINE TRANSCEIVER

Long Range Communications Beyond the Horizon

IC-M803 adalah radio komunikasi digital jarak jauh untuk semua kapal penjelajah. Jangkau frekuensi laut dan ham dengan sertifikasi DSC MF / HF Kelas E. Dikemas dengan fitur seperti tombol panggilan darurat, pemutar ulang audio, GPS dan banyak lagi untuk menjaga pengguna tetap aman. IC-M803 juga memiliki layar TFT berwarna dan kesamaan antarmuka dengan pengguna M605 yang memungkinkan pengoperasian yang mudah antara dua radio. M803 juga mencakup sistem pengambilan sampel sederhana langsung RF canggih yang meningkatkan sensitivitas penerima lebih tinggi dan audio berkualitas lebih tinggi.
