I've just built a set (80 meter to 10 meter) of Ed Wetherhold W3NQN Transmit BPFs. They are great with an insertion loss of around 0.3dB. The following is a link to the article:
<http://www.kitsandparts.com/W3NQN_May_June_1998_QST.pdf>
In Ed's article he uses a program called "BASIC Program Calculates Many BPF Designs" to help him design BPFs. I haven't been able to find a copy of Ed's BASIC program. Anyone knows where I can get a copy? I would like to have a go at designing a 30 meter Tx BPF.
Would also appreciate any comments on Tx BPFs design.
Thanks for your help,
Roderick Wall, vk3yc.
