Vertex VX-1700

Vertex VX-1700 is a universal HF radio station intended for organizing long-distance mobile radio communications. VX-1700 can be used not only as a mobile radio station, but also as a base station, allowing to organize complex radio communication at short distances with minimal expenses.

Vertex VX-1700 can store up to 200 channels and split them into five groups with any number of channels in a group. Each programmed channel can be assigned a 6-digit alphanumeric designation, which greatly accelerates and simplifies the management of calls. The VX-1700 supports six communication modes:
  • SELCALL (selective call)
  • TELCALL (phone call)
  • Message Call (for text messaging)
  • Position Request Call
  • Position Send Call and Beacon Request
  • Call (to check the signal quality).

The choice of channels is carried out depending on the requirements of the user.

The VX-1700 has 4 programmable keys, a noise reduction mechanism, and a number of the following functions: CW Semi break-in function, CW Sidetone function, VOX function. Dual Watch mode allows, on a single channel, to periodically monitor another recorded channel. This function is especially useful in emergency situations, when it is very important that no call is missed.
