Matek 1G3SE Setup

To use the Matek 1G3SE with IRC Tramp. You will need to enter the CLI command set vtx_frequency_group = FREQUENCYGROUP_1G3. You must also make sure that the initial VTx settings in the configuration tab are in a valid range. They are:

• vtx_band 1 or 2
• vtx_channel between 1 and 8

Note: The frequencies required by the US version of the VTx are on vtx_band 2 (BAND B) only.

Team BlackSheep SmartAudio

If you have problems getting SmartAudio working. There are a couple of CLI parameters you can try changing to see if they help.

• There is a workaround for early AKK VTx modules. This is enabled by default. You could try disabling this setting vtx_smartaudio_early_akk_workaround to OFF.

• If you are using softserial, you can try using the alternate method by setting vtx_smartaudio_alternate_softserial_method to OFF.

• If you are using TBS Sixty9 VTX you may consider to set count of stop bits to 1, using set vtx_smartaudio_stopbits = 1
