VX-1700 multi-mode mobile HF radio features

Large Channel Capacity
The VX-1700 can store 200 channels arranged in five groups with the flexibility to have any number of channels per group. Each channel can be programmed with a 6-character alphanumeric description for quick and easy call management.

Automatic Link Establishment (ALE) Option
With the ALE-1 option installed, the VX-1700 Automatic Link Establishment feature selects the channel with the best LQA (Link Quality Analysis) score from the programmed channels automatically.

Flexible Calling Options
The VX-1700 provides six different built-in calling modes to support various communications requirements including SELCALL, TELCALL, Message Call (for text messages), Position Request Call, Position Send Call and Beacon Request Call to check signal quality.

Dual Watch Operation
Operate the VX-1700 radio on one channel while periodically monitoring the designated memory channel to ensure a call is not missed. Ideal for emergency management situations when it is important that a call gets through to dispatch.

Additional Features
• Four programmable keys
• Noise blanker
• CW Semi break-in
• CW Side tone function
• VOX
• VFO Mode
• Field memory channel storage
