This page describes how to safely connect a software defined radio to your transceiver using a DXE-RTR-2 relay box to create a real-time spectrum analyser (panadapter) to your shack. One way to connect an SDR and transceiver is by using a relay box to disconnect the SDR when transmitting automatically. SDR radios can be damaged by transmitter power when an SDR and transceiver share the sameĪ switch can be used to flip between SDR and transceiver, but this prevents the use of your main receivers audio signal making this setup a bit awkward. Sound car assembly 1) The USB sound-card plugs directly into the USB isolator, this assembly plugs into your PC or Raspberry Pi Audio cables 2) The Green jack socket of the sound card connects to the Microphone I/P of your radio.
Transceiver and SDR? Unfortunately, it's not possible to simply attach an SDR directly to a transceiver. You will need to be able key your rig via the CAT lead using your chosen data mode software.
How do you connect your antenna to both your e Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. SDR radios are relatively cheap and available, these will provide a spectrum view right out of the box, but on their own, this isn't enough. When working HF, this is very useful as it allows you to quickly home in on CQ calls and A panadapter allows you to see all of the radio stations currently transmitting across an entire band.
