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

I would use heat from a heat gun to soften the resin and pick it out with fine tools. In my experience, their just isn't a really good way, fast way. Do a little area at a time with minimal heat to avoid cooking the resin and causing a bigger mess.

Best of luck!
