Opticum AX Black Buster Twin now Red Eagle Black Buster Twin

Some days ago i bought on eBay a "Opticum AX Black Buster Twin" LNB.

But today arrived a "Red Eagle Black Buster Twin".

Opened it and it is exactly the same PCB, only the names have changed...

Inside ist the good RDA3565S PLL/Mixer IC with 27MHz Crystal known from the old Octagons

73s DB8TF

And here is a Pic which components have to be removed/changed to inject external LO.

With the usual 27MHz bandpass and mod to the DC choke it works very nice with only one coax wire.

With 26MHz the PLL won't lock but with a cheap 27MHz OCXO everything works nice
