Hi Patrik,
Thanks for the info. It’s quite good reception you have with the TVRX.
Did you use any low noise amplifier in front of the TVRX?
Cheers
Alex

Hi Alex,
I used a 1.2 m long X-yagi and a cheap broadband TV pre-amp
http://www.vekoy.com/product_info.php?cPath=85_402&products_id=12828
EZNEC told me I should get ~14 dB Gain with this gadget, It sure works!
The boom is a PVC pipe and elements are 3.2 mm Al/Ag TIG welding rods, <
$20
An image of the antenna and txt how I made the X-Yagi is at

It is tricky to follow the downlink frequency change due to doppler…

Hi Patrik,
Thanks again for the info. I like your home made yagi antenna for UHF.
I will try to build one in the holidays.
Implementing Doppler correction in GNU Radio receiver can be

and performance:
