I was trying to run it with AD6645-105 and overclock it to 122.88mHz, but ADC chip was dead 🙁 Ordered new one
Replaced inductors with non-smd: 160m: New: 80m: Old: New: 40m: Old: New: 30m: Old: New: 20m: Old: New: 18Mhz: New: 15m: Old:
There is some tuning needed, but almost nothing to solder anymore, just 2m filters mods required. And all works.
There are some place for modifications and tuning, but… assembly for big wolf is finally finished… I hope I’ll never repeat it
I’m using not best quality 0805 inductors (it’s just too hard to buy good here in Batumi) from aliexpress so BPF loss
Plus couple photos.
