This is result of the second pass of the Milky Way (from last night, antenna was pointing upwards).
I am still not entirely sure about accuracy of frequency calibration (1.4204 is middle peak on the test track), generated by HP8922M, set to 710.2MHz.. so on the screen is first harmonic), but the two peaks of the 21cm signal are very obvious.
Guys, our Galaxy is still rotating! Confirmed
