== Scope ==

The new Es'HailSat from Quatar has received wide attention. Let's start to play with it. The first step is to receive it's signal. 

By coincidence I purchased an LNB with a LO frequency of 9 GHz some years ago, while never using it. Now the occasion has come to really use it. Yet, some more components are missing:

* A DC injector
* A receiver component
* A satellite dish

=== LNB ===

There are vendors on Ebay who sell modified LNBs for a small price:

I have one from Dieter DL2KBH:

I am using another one also:

 Product Name: Octagon Single LNB Slim OPTIMA
 Input Frequencies: 10.70 - 12.75 GHz
 LO: 9.75 / 10.6 GHz
 Noise figure: 0.1 dB
 Amplification: 60-65 dB
 High polarization separation
 High frequency stability
 Feed diameter 40mm

=== Injector ===

This component needs to be home built.

And here it is:

A measurement with my Spectrum Analyzer (with tracking generator) showed that the insertion loss is around 5dB. That's quite a lot, but my expectation is that the LNB will give me a considerable boost so that this loss is not relevant. We will see. 

I changed the 1N4001 diode into a 1N4007 type. 

And I left the fuse out. Fusing shall be done differently, as just for this test.

=== Receiver ===

I envisage to use two different receivers: 

* USRP2
* NooElec RTLSDR Stick
