Description détaillée
Description détaillée
The Icom IC-M73EURO PLUS portable VHF is a marine transceiver designed for demanding maritime communications. This "PLUS" model stands out from the standard IC-M73EURO with exclusive advanced audio features: voice recording, bidirectional active noise cancellation, and bass enhancement, delivering superior sound clarity compared to standard 5W portable VHFs with IPX7 rating.
Exclusive audio features and RF performance
The IC-M73EURO PLUS includes a voice recording function that automatically saves the last minute of incoming communication, with an option for manual recording. The bidirectional active noise cancellation technology reduces ambient noise by up to 90%, optimizing the intelligibility of transmitted and received voice. The Bass Boost feature enhances the audio spectrum through signal processing that emphasizes low frequencies. With an RF output power of 6W (adjustable to 3W/1W), exceeding the standard 5W market offering, and a BTL amplifier delivering 700 mW via its internal speaker (200 mW via external speaker), the IC-M73EURO PLUS ensures extended communication range and optimal sound reproduction. Its frequency stability is ±1.5 kHz, with adjacent channel rejection of 70 dB.
Robustness and environmental specifications
The IC-M73EURO PLUS portable VHF is IPX8 certified, ensuring resistance to immersion up to 1.5 meters for 30 minutes, surpassing the requirements of many competing models often limited to IPX7. Its design complies with MIL-STD-810G military standards for shock resistance (method 516.6, procedures I, IV), vibration (514.6 I), extreme temperatures (501.5 I, II; 502.5 I, II), thermal shock (503.5 I-C), solar radiation (505.5 I), rain (506.5 I, III), humidity (507.5 II), salt fog (509.5), and dust (510.5 I). Powered by a Li-Ion BP-245H battery, it offers up to 17 hours of autonomy (5:5:90 duty cycle), ensuring prolonged use.
Ergonomics and connectivity
With compact dimensions of 52.5 × 125 × 30 mm (excluding projections) and a weight of 320 g (with BP-245H battery, FA-564V antenna, MB-103 clip), the IC-M73EURO PLUS features a slim and ergonomic body. Its wide-angle LCD screen ensures optimal readability. Transmission frequencies range from 156.000 to 161.450 MHz and reception from 156.000 to 163.425 MHz, supporting INT and USA channels. Power consumption in transmission at 6W is 1.5 A, and in maximum audio reception is 450 mA (internal speaker). Its sensitivity is -4 dBμ·emf typ. (at 20 dB SINAD), adjacent channel selectivity is 70 dB, and intermodulation is 68 dB, guaranteeing reliable reception performance. Connectivity is provided via a 50 Ω SMA antenna.
