I buy this "Zolotarev-LPF" made by LA2NI, and this board is first now on the table and I am soldring coil and caps on it
but I got some problem whit it...but as we sadly know Kjell is now SK, and not able to help anymore.
my problem it that the 3 first filter-bank is ok...but the last 3 bank (30+20m / 15+17m / 10m) is out of range, only 12m is ok ???
all coils material and most caps is from Kjell
so my qustion is if there is anyone here in the groupe there have buld this "LA2NI / Zolotarev-LPF" and also having same problems and how to cure it
