This page contains the answers to the most frequently asked questions about the OL-Master software.

Can I use Tethis as software to manage Olliter SDR?

No, Olliter SDR has a proprietary communication protocol that is not compatible with other software such as Tethis, PowerSDR, or SDR Console. Some DLLs might be available in future releases to allow the use of third-party software.

Can I interface Olliter SDR with my linear amplifier?

Yes, by adjusting the output power and (optionally) connecting the PTT and band change signals, it is possible to interface most of the amplifiers available on the market.

Additionally, using a properly sized attenuator, a feedback of the forward power can be passed to the PureSignal input of the transceiver to allow the use of the PureSignal algorithm and reduce the distortion of the transmitted signal.

How can I connect the "CW Skimmer" decoding software to OL-Master?

First of all, you need to download and install on your computer a software that creates one or more "Virtual Coms", then you will need to download and install on your computer a software that creates a virtual Audio routing (VAC = Virtual Audio Cable). Once this is done, you will start the OL-Master software and, entering the Setup panel, you will assign one of the VACs to one of the virtual cables created previously. You can repeat the operation for all four VACs present under the Audio panel within the Setup panel. Remember to check the box to enable the VAC (e.g. VAC RX1 enable) in addition to the Direct I/Q enable box: Output to VAC. Always under Setup, within the COM panel, you will enable one of the CAT ports by assigning it to one of the virtual ports created previously. Once this is done, you will download the OL_SDR parameter definition file from our website and copy it to the CW Skimmer folder. At this point, you can start CW skimmer and configure it to interface with the VAC and VCOM ports created previously.

How can I transmit in Split with OL-Master?

Just activate the RIT or XIT. Through the Xit, the transmission frequency will be moved by +xxxx Hz compared to the reception frequency indicated on the frequency meter display. During transmission, it will be noticed that the frequency is shifted compared to the reception frequency indicated on the frequency meter by +xxxx Hz. It is important to remember to activate the functionality by pressing the XIT button, whose writing will turn red. The same effect can also be obtained with the Rit. The only difference is that the Rit moves the reception frequency by +xxxx Hz while the transmission frequency remains the one set and displayed on the frequency meter.

You can also use the sub receiver feature to transmit in split. The sub receiver is a second receiver that can be used to listen to a different frequency than the main receiver. The sub receiver can be activated by pressing the SUB button. The sub receiver can be tuned independently of the main receiver. For example:
