Hi Riffad
I have just updated the files for the Irwell 2nd Mixer stage & Post mixer amplifier and the NEW schematic contains diplexer component values for 9MHz as well as 11.059MHz
Please take a look in the files section under
2020 Receive Mixer Stage (DBM)It is late now in the UK and I need to get off to bed but I will look at alternative SMD transistors for the NE46134 and get back to you hopefully tomorrow.
For now best regards...
