|  Removing resin from a 49:1 sealed transf  |

 TID: Mystic BBS 1.12 A43 MSGID: 2:240/8001 b20cf4cb TZUTC: 0200 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 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: 50/22 103/705 105/81 106/201 128/187 129/14 305 153/7715 SEEN-BY: 154/30 110 218/700 226/30 227/114 229/110 111 114 200 206 SEEN-BY: 229/307 317 400 426 428 470 616 664 700 705 240/1120 1634 SEEN-BY: 240/5832 8001 8002 8005 8006 8050 263/1 266/512 280/464 5003 SEEN-BY: 280/5006 291/111 301/1 310/31 313/41 320/219 322/757 335/364 SEEN-BY: 341/66 234 342/200 371/0 396/45 423/120 460/58 256 1124 5858 SEEN-BY: 467/888 633/280 712/848 770/1 902/26 5020/400 5054/30 5058/104 SEEN-BY: 5075/35 PATH: 240/8001 1120 280/464 460/58 229/426 |
