Troubleshooting

This manual contains some issues that may occur while operating the transceiver, if the proposed solution does not work for you, please get in touch with the customer care department.

Olliter SDR Not Powering Up

Some linear power supplies with large filtering capacitors can cause the Olliter SDR to power up improperly if it is connected before the power supply is turned on. This occurs because the slow charging process of the power supply's output filters triggers a low voltage alert in the transceiver, activating the protection circuit and cutting off the power.

Solution: Resetting the Protection Circuit

If the Olliter SDR does not show the green light when pressing the power button after turning on the power supply, follow these steps:

By following these steps, the protection circuit should reset, and the Olliter SDR should power up correctly. If the issue persists, ensure all connections are secure and the power supply is functioning correctly.

OL-Master reporting an error at startup

If the OL-Master software throws an error at startup stating "Cannot load DLL 'ChannelMaster', cannot find the specified module" means that some dependencies are not satisfied.

Solution: Refer to the System requirements chapter and make sure all software and hardware requirements are met.

OL-Master software crashed

If the OL-Master software crashes, it may be due to a variety of reasons, to help us diagnose the issue, please follow these steps:

The following additional details will help us diagnose the issue and provide a solution:

No voice from the front-panel microphone when transmitting

This issue can relate to multiple reasons, both software and hardware.

VAC is enabled on the receiver

VAC will have priority over the microphone audio when transmitting, make sure the VAC is disabled on the current receiver from the Setup menu to enable the audio stream from the microphone.

Solution: disable VAC for the receiver that is being used

Wrong microphone style

Each transceiver is shipped with a dedicated microphone wiring, a different brand of microphone cannot be used without switching to a new wiring kit. Contact the customer assistance service to receive information on the wiring that was shipped with your transceiver or to request a new microphone wiring kit.

Solution: verify the microphone wiring that was installed

Wrong microphone voltage

Different microphone brands have different settings, make sure the right microphone supply voltage was selected in the Setup menu.

Solution: verify the microphone supply voltage

Improper microphone gain setting

Microphone gain is set from the upper-left panel of the OL-Master software when in SSB mode, adjust the slider to get a good quality of the transmitted audio.

Additional settings can be found in the Setup menu, like preamplifier or the adjustment range of the main slider.

Solution: verify the microphone gain.

Additional windows (like EiBi or Cluster) are not showing up

Windows sometimes "hides" some UI elements outside the screen boundaries, just restore the window position to show it up.

Solution: Restoring the new window position

Hover the mouse to the OL-Master icon in the Windows bar (usually the bottom part of your screen), you should see two or more windows as in the picture

Restoring window position

Right click on the window that has disappeared (the DX Spider Client in this example) and select "Maximize". The window should now appear on your main screen fully maximized, click on the title bar and drag it anywhere to return to its normal size. The new location should be stored in the database and recovered at the next reopening.

User interface is not updating or feels slow

If the UI is laggy or unresponsive, it may be caused by a CPU overload, the bottom bar of OL-Master shows the CPU utilization, if this is too high, or even if the number is low but the interface feels "slow", please consider closing other software running in background or use a more powerful computer.

Another way to reduce the computing load of the software is to reduce the sample rate from the OL-Master "Setup" menu, closing additional receivers, turn off some advanced filtering (like NB2 or NR2) or disabling external services like cluster or EiBi.

Please remember that on SDR devices, the biggest part of the job is performed by the computer, so a powerful transceiver, requires an adequately powerful PC.

Solution: Reduce the sample rate, close all background applications or consider a PC hardware upgrade

Audio from the speakers feels clicky or saturated

Audio levels is monitored by the AGC algorithm, if the AGC is set to any manual setting and the volume is too high, the audio will be saturated and sound bad.

Solution: lower the audio volume or enable AGC

I connected the transceiver to a different PC and all settings were reset

Settings of the transceiver are not stored in the transceiver itself, they are stored in an xml file which lives in the %appdata%/OL-Master folder of the control PC. This file should be copied across the different devices where OL-Master is installed

Solution: copy the database file to the new PC

I get a weird error at startup telling my database cannot be loaded for some reason

The database probably got corrupted due to some hardware or software issues, automatic backups are created by the software in the %appdata%/OL-Master/Backups/Automatic folder, these files can be copied back to %appdata%/OL-Master and renamed to database.xml to restore a previous configuration

Solution: restore one of the automatic backups of the database
