Setting up your SDRSwitch.


Setting up your SDRSwitch could not be easier. 

Your SDRSwitch can be configured in numerous ways but this is the most simple configuration.

Your SDR Receiver of choice connects to the RX BNC on your SDRSwitch and to your computer. Your computer becomes your radio when running software such as SDR Console.  Your transmitting radio connects to the TX BNC whilst your antenna is connected to the ANT BNC.

Information on setting up your SDR RX with SDR Console, WSJT and Virtual Audio Cables etc. can be found here.

Although the above set up would be the basic set up for HF many VHF operators will wish to achieve the best possible VHF RX out there by installing an LNA (PreAmp) in order to set the initial noise floor of there SDR RX and add a Band Pass Filter.  As the LNA sets the initial Noise floor of your RX it should be installed after the LNA. Not only does this set the best RX noise figure for your your SDR receiver but all BPFs have an insertion loss. The excess gain from your LNA helps with this loss and indeed due the amount of gain you have it can also be of an advantage.

The diagram below shows the RX path (Green Arrows) of the SDR Switch.

The rear connections are just as simple to make with the 12VDC going to your 12VDC shack PSU. The PTT going to your transceiver PTT out. Usually an RCA connector. The AUX is a ground loop and can be used to key and accessory such as an amplifier or a transverter.
