10GHz OpenWEB RX at OL7M QTH

During the playing with RTL-SDR I have decided to try 10GHz OpenWEB SDR at OL7M. There are very nice and cheap LNB converters with PLL and 25 MHz X-tal. I found cheap TXCO in China for a few USD. So this was really nice way to start building stable and cheap 10 GHz converter for the RTL-SDR. And what more, split two LNBs to two directions. It means 3 dB more noise, but why not. 

We do have new tall tower which has got nice view in 360 deg. First LNB looks to N-W and second one to South. There are easy copy OK0EA and SR6XHZ and during RS conditions also OE beacons.

And easy modification for cheap RTL-SDR with new TCXO: HERE

Simply CNC 2417 milling machine assembling

   A few months ago I bought simply and cheap CNC Milling machine from China. It is CNC 2417. You can find it on Ebay or Banggood. It came without any instructions, but I found good one here. Some more 3D printed mods are here.
   And there are some photos from Sunday afternoon which we spent with my girlfriend Luciiik in my job :) with CNC 2417 assembling.
