Hi All,

After I do not know how many years, I'm back here on the net :).
So back to the primary topic:
Recently I've purchased an 49:1 unun from a manufacturer, but I am not
satisfied with the performance of it (compared with another 49:1 transformer
the SWR is notably higher.
Therefore I plan to dissassemble it completely, but the main problem is that
the ferrite inside the box is sealed wit a resin. I would like to hear your
opinions or experience, how to safely remove the resin without
damaging/destroying the ferrite ?

Thank you
