To get working device faster i decided to just buy prebuilt modules from 60dbmco located in Kyiv Ukraine. They’re still selling their devices and deliver them fast.
There is no reason to use BPF in the city with LTC2208, i bought it just to prove that fact to myself 🙂
RX-TX switching board:
It’s 100W RD100HFF based amp with schematic similar to Munin from hpsdr project and others.
I can’t recommend to buy this case, because it’s small and unhandy but it looks pretty nice.
