Hello,
I have made a frequency change for my station 858 in Stockholm. The new frq is now 430 - 460 MHz. I will add a LNA and Band Pass Filter for the amateur radio 70 cm and the frequency respons is according to the image below.

I know that many has been using my station for scheduling satellites in the 400 MHz area. This area is outside my interest - I would now like to improve the station RX for 70 cm band.

Regards
