The HT644 ATIS is designed specifically for use in navigating inland waters in continental Europe. An FFSK data signal is located at the end of each transmission, which contains information about the vessel, including a call sign unique to the vessel that must be tracked and monitored for safety purposes.
Entel HT644 VHF is fully compatible with MIL-STD 810C / D / E / F for durable performance and fully submersible to IP68 . Entel's portable HT644 will exceed the expectations of even the most experienced radio user. The HT644 features the latest intelligent lithium-ion battery technology. The socket is designed so that when attached to the portable computer, the connection will withstand any kind of punishment; from dropping to careless abuse. To prevent accidental operation, your radio's buttons and controls can be locked or, if set, automatically locked by the radio.
If you use Entel VOX audio accessories, your HT644 portable can operate completely hands-free. All you have to do is talk and the portable will automatically transmit for you. The HT644 has the ability to actively search for a channel. When the channel is found, the radio will automatically select the channel for you.
