  • ARS-USB_YAESU

    This is a special version based on the ARS-USB that was re-designed to be used as a rotor controller or replacement for a Yaesu Control Unit (or similar rotators) that operates in DC.

    It includes the same features as the standard ARS-USB adding some extra as:

    • Simple and easy calibration at any rotor position in few steps.
    • Soft start and stop via a PWM. It allows to have a soft starting/stopping ramp.
    • It detects if the potentiometer is out of range and will prevent any accidental problem with the antenna coax. Any problem with the potentiometer or cables are detected inmediately
    • If the motor is jammed by any reason, an alarm will be displayed and the appointment will stop. The user will be noticed.

    All those watch-dog systems (and some more options) will prevent to generate a problem if the potentiometer is damaged by any cause (any wire broken, moisture, a wrong cable connection, etc).

  • Raspberry Pi 3 B+

    This is a great and low cost solution for a remote control of the rotors or when there are several local rotors and you wish to control any of them in a simple way. You will connect the ARS-USB to the Raspberry Pi (USB port) and then you can use the ARSVCOM (TCP/IP connecton) or via a simple browser to control the rotator via RemoteRotator.

    One Raspberry Pi can support as many ARS-USB as you need. 

    The same Raspberry Pi can be used for any device as:

    • ARS-USB
    • RemoteBox
    • StackMain

  • TRX-FEL

    The TRX-FEL (Transceiver Front End Limiter) is a RF protector and limiter for your radio transceiver. Installed between the antenna or amplifier and the transceiver, it requires to be connected the PTT signal from the radio. By default (reception) it will limited any RF signal and will avoid to damage the receiver in the proximity to other transmitters. When the PTT is activated by the radio, the Front End Limiter will be by-passed.

    This model is highly recommended in multi operator contesting, SO2R or Field Day. 

    Specifications in RX (FrontEnd activated)

    • Insertion lost better than 0.4dB in HF (1.8Mhz - 50Mhz) 
    • VSWR < 1.06:1 Range 1.8-29Mhz

    Specifications in TX or ByPass (FrontEnd disabled)

    • Insertion lost better than 0.04dB in HF (1.8Mhz - 50Mhz) 
    • VSWR < 1.05:1 Range 1.8-29Mhz
    • Max power 150W
