Ah, so a multiply_const with a constant of
$e^{j\frac{2\pi}{f_\text{sample}\varphi}$, yeah.

Well, you can't see absolute phase without further ado – that would need
your TX and RX to be phase-synchronized (you don't know the electrical
length between your transmitter and receiver, it's absolutely random by
itself).
