What happened?

Hello,

I am controlling AetherSDR via TCI protocol from a Node.js server connected to a Stream Deck+, using a Flex 6600. AetherSDR reports TCI protocol version 1.5.

Aether version : v0.8.18

I am trying to control TX power (DRIVE), audio volume (VOLUME / RX_VOLUME) and Split mode remotely via TCI.

Observed behavior:

When I send the following commands from my TCI client, AetherSDR does not respond and the values do not change:

• DRIVE:0,50; → no effect, power drops to 0 if previously set manually to another value
• VOLUME:50; → no effect, no acknowledgement
• RX_VOLUME:0,0,50; → no effect, AetherSDR replies with the old value
• SPLIT_ENABLE:0,true; → no effect, no acknowledgement

However, when I read the current values:

• RX_VOLUME:0,0; → AetherSDR correctly replies rx_volume:0,19;
• DRIVE:0,27; → AetherSDR correctly sends current value at startup

Also, when I change TX power or volume manually in the AetherSDR GUI, nothing is broadcast to TCI clients — so I cannot even track the current value.

Expected behavior:

According to the TCI v2.0 documentation, DRIVE, VOLUME, RX_VOLUME and SPLIT_ENABLE are all bidirectional commands and should be settable by a TCI client.

Questions:

1. Are DRIVE, VOLUME/RX_VOLUME and SPLIT_ENABLE currently implemented as writable commands in AetherSDR?
2. If not, is there a planned fix or a workaround?
3. Is there another TCI command to control TX power, audio volume and split mode?

Thank you for your help.

Best regards
