Hi All,
After I do not know how many years, I'm back on FidoNet
So, back to the primary topic:
Recently I've purchased a 49:1 unun from a manufacturer, but I am not satisfied of it's performance (compared with another 49:1 transformer, the SWR is notably higher). Therefore I plan to dissassemble it completely and use the ferrite for another project, but the main problem is that the ferrite inside the box is sea led with a resin. I would like to hear your opinions or experience, how to safe ly remove the resin without damaging/destroying the ferrite ?
