Only I or Q channel carrier wave transmit?

[luoGanda]

What would you like to know?

can this be done?
maybe am i missing something that already works in this direction?

Don't know much about hardware underneath,
but as i see it - one carrier wave channel is passed as it is and the other 90deg outOfPhase(and this is how it is read also).

One can modulate carrier wave with I and Q values, but what about carrier without modulation?
Eg putting 0 for I channel and any value in Q - can this vars be accessed somehow?
Is there a way to do this? if not - maybe via adding simple firmware code?

I wonder if portapack Utility->Signal generator does this?

Not sure if this would be an easy task to code, but it would be an handy option.
