Hello all
I am working on modifying the K2 bandpass filters to more"european" conditions. by the article written by DL7MAJ, and I can assure you all, that a networkanalyzer is very handy at this job. I am not sure it would be a menial task otherwise. But I have run into a problem on where to obtain 3900pF NP0 caps? I have not been able to locate that value anywhere, so if any of you guys can help I will be very happy. I miss 2 and they are for the 80 / 160 m filtersection. Following DL7MAJ's very good article on filter mods, I can tell that the values he sugest are OK. I will post a further mail if I find any differences in my work with the last sections. 73- Henning OZ4XF happy owner of K2 #3431 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Order e-mail is [hidden email] Web is www.elfa.se My catalogue is over a year old, so they might have other NPO styles now in qtys of one. 73, Geoff GM4ESD ----- Original Message ----- From: "Henning V.
