Replaced inductors with non-smd: 160m: New: 80m: Old: New: 40m: Old: New: 30m: Old: New: 20m: Old: New: 18Mhz: New: 15m: Old:
Replaced inductors in BPF — 2 handmade and other non-smd inductors from aliexpress. I forgot to make a photo of the result
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
SWR was increasing and power was lowering. Was trying to figure out whats wrong… Finally…
I’m using not best quality 0805 inductors (it’s just too hard to buy good here in Batumi) from aliexpress so BPF loss
