Report from 10 GHz polarization test held on April2, 2006 

TX station:
Bochum 20m dish, QRG:10368.500 MHz, TWT 40W (?), CCW, 2006-04-02, 13:00 … 15:00 Z
DK0SB (DL_AMSAT team)
Records:
Three original consequent in time vaw files named 1, 2 and 3 each comprise of 19 particular audio parts interrupted by a zero signal breaks. 
Each audio part carries audio signal rcvd via Spectran for every 10° step of polarization angle 
in the range from  -90°. …. -0° …..  +90°.   
The last fourth file named 0 contains long record of the rcvd signal at 0° for the rest of the test time.
The 0° position equals to vertical position towards local ground surface.
Antenna (dish) controlled by Az-El tracking with accuracy better than ± 0.1 deg.
Measured BW(-3dB) ≈ 0.5deg at 10.368 MHz.
Rig settings:
IF - TS870: USB, low=100 Hz, high=1600 Hz, AGC off, rf and nf unchanged through the whole test, audio output monitored in parallel by an audio meter. 
Frequency tuning corrected just to eliminate Doppler with the aim to held approx. 1 kHz of the peak frequency.
Spectran/NB connected directly to TS870S (via ACC2 rear connection). 
Details: OK1VAO, please, add some more details if required

Rmk:
Before starting the record of each particular audio file the pointing to the Moon was checked and slightly corrected (with accuracy better than 0.1 deg) to eliminate any impact of potential improper pointing to the Moon.  

System parameters (measured before and after the test; sorry, performance worse than expected; seems we really have some deficiencies along the receive path):
G/CS   cca 3.4 dB
Moon   cca 1.6 dB

Equipment used:
Dish 4.6m, f/D=0.43
Feed: long pyramidal horn with mechanical rotating by +/- 90° (feed reflection <<-20 dB)
LNA: 3 stages, NE32584 (“D”) on the first stage, NF was under 0.8dB some years ago (hi)
Home brew transverter 10368 or 10450/145 MHz + Transverter DEMI:  145/29 MHz
IF RX: Transceiver Kenwood TS870S 29 MHz
