>I'd like to build up several toroid chokes for 160, 80 and 40 meter use. Lloyd Take a look at this: http://www.ifwtech.co.uk/g3sek/in-prac/ and this: http://www.ifwtech.co.uk/g3sek/in-prac/inpr1005_ext_v2.pdf I have built a 3-band choke based on his design, and it works very effectively on all the HF bands. The low-band and mid-band chokes will probably cover your requirements. -- 73 Ian, G3NRW _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
