Detail SSB VERTEX VX-1700
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
