PTT over Ethernet

  • Hallo,

    for those who like to control their amplifiers idle current, my idea is to send a PTT-Signal via Ethernet to the Radio which can be placed far away (Pluto and amplifier) closed to the dish. To avoid confusion, the PTT-Signal is switching the amplifier to transmit. For this special solution the Pluto is not involved.
    PoE-Adapters gives Ethernet and two independend lines for a very low price. The PoE-Plugs can be removed or changed (in my shack to Cinch).



    The PTT-Signal at the PC-Side is generated with a USB-Relay. The Relay is supported by the Console if it is conform with HID-Standard.

    I just tested the adapters, works nice. It is possible to use a PTT-Signal from GPIO-Ports of the Pluto also but there is a delay of about 800 ms switching on and off.

    Have fun with fluently SSB-Speaking.
