|    Removing resin from sealed 49:1 unun box    |

      TID: Mystic BBS 1.12 A43       MSGID: 2:240/8001 4270b1b2       TZUTC: 0200       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 ?               73 de Z32X              --- Mystic BBS v1.12 A43 2019/03/03 (Windows/32)        * Origin: BlackICE BBS (BlackICE.BBSindex.com:23) (2:240/8001)       SEEN-BY: 18/200 105/81 106/201 128/187 129/14 305 153/7715 154/110       SEEN-BY: 218/700 221/1 6 226/30 227/114 229/110 111 114 200 206 300       SEEN-BY: 229/307 312 317 400 426 428 470 664 700 705 240/1120 1634       SEEN-BY: 240/5832 8001 8002 8005 8006 8050 266/512 280/5003 291/111       SEEN-BY: 292/854 301/1 113 812 313/41 320/219 322/757 335/364 342/200       SEEN-BY: 371/0 382/200 396/45 419/802 460/58 256 1124 5858 530/204       SEEN-BY: 633/280 712/848 902/26 5020/400 1042 8912 5030/723 5054/30       SEEN-BY: 5075/35       PATH: 240/8001 1120 301/1 460/58 229/426           |
