Retevis RM40 use feeling
Retevis RM40 marine radio has been in hand for some time. Compared with the previous RT55 and RA26, the first is that the appearance has changed, the panel is richer, and many functions are triggered directly by buttons. There is no need to search the menu, which looks more professional. The battery adopts polymer lithium battery, and the battery capacity also reaches 1500 mAh. The specially equipped antenna can effectively improve the communication distance of RM40 and improve the reception sensitivity of short wave. The second is the carefully calibrated squelch function, which effectively reduces the environmental noise and makes the RM40 have better sound quality on board.
RM40 has a good power-saving mode and a high-definition and high contrast screen, which can effectively reduce the power consumption of backlight. At the same time, the 1500mah lithium battery also provides guarantee for the endurance capacity of RM40. Through the test, it is found that the endurance time of RM40 in standby mode can reach 12 hours, and the normal use time is more than 3 hours, which fully meets the daily use of fishermen, sailboats, yachts, passenger ships, wharf dispatchers and other staff.
Another highlight of RM40 is the addition of DSC alarm function, which makes the handheld marine radio more practical. In case of emergency, the RM40 in hand can directly send geographical location and alarm information to surrounding ships or coastal radio stations, which can quickly alarm and get assistance at the first time. It is much more convenient than calling or calling the cockpit for alarm in this process.
There is not much to say about the call distance of RM40. The positioning of this marine radio is a long call distance. Generally, it can reach 10-15 nautical miles. In bad weather, it can also have a call distance of 5-8 nautical miles. This call distance is very eye-catching among handheld marine radio.
As lovers of marine radio, they often buy and try new radio when they appear to see what different functions, appearance and so on. At present, RM40 meets my expectations. I hope its performance can be maintained stably and has a good reputation.
