Subject: Re: [4SQRP] Filters for portable ops
 
I posted a couple of presentations I did a while back on homebrewing filters using ELSIE and Altoids tins. These were meant as an overview of the process and results rather than specific recipes of filters for each band. I lost some of the calculation and software design files in a PC crash a couple of years. At that point I had working bandpass filters for 40, 30, 20, & 17 Meters and an AM broadcast filter.
