Max MER 18 dB . About 6mn of video/TS

2.395 GHz 14.50 UTC .. TS OK lock for approx 6 minutes on high elevation pass (73 degrees) in flip mode

I also managed to get about 30" of TS decoded using my fixed low-gain antenna (TECOM 12 dBi RHCP helix, pointed at az=215°, el=70°).

To avoid local interference, I have included a tunable bandpass filter in the IF between the cinese LNB and the TT 3200 receiver card (decoupling the DC path with a DC-bias coupler from Minicircuits, and using an external power supply).

This is the data recorded during the pass at the maximum elevation.

2395 MHz, SR=1300

The following image is the signal received in the spectrum analyzer, coupled with the IF coming from the LNB. In the spectrum image, the carrier which appears in the middle of the received signal I think is a ringing due to the noise coming from the LNB passing through the filter. Bandwidth of filter is 30 MHz. Signals in the spectrum analyzer are amplified 10 dB (directional coupler -10 dB, line amplifier +20 dB). Noise level displayed is the noise coming from the LNB, which is only +3 dB from the noise level of the spectrum analyzer.

Signal received at maximum elevation (see description)

Very good results today

Very happy with todays activity's, the blank transmissions have been very useful for fine tuning the system.

This morning I tried again a pass using at same time 2 PC, one with TT S2-1600 and one with TT -S2-3200.
I stopped the recording too early , so we do not have the end of the pass.

Received ISS HAMTV using 2 MS/s on 2.395 GHz at 13:02 UTC 23 March 2014. Piero I0KPT informs me that this is the first reception of 2 MS/S

Setup: SR2000 - using 1.20 meter dish, LHCP home brew S Band Patch, Kuhne down converter, TT S2-1600, Yaesu G-5500 rotator, GS-232B controller and SatPC32 tracking software.

My first RX of 2MS/S.
Lost the TS at 1300KM range
