Hi David,
Thank you for your kind email and your offer. I do not use Spice simulation for my projects, normally I design filters with Elsie or AADE software and simulate its behaviour on WinDipoles. The SCR Preselector is a bit complex project because its features. I know the works that you indicate. N1KPR has a comprehensive set of preselectors intended mainly for Broadcast DXing. YU1LM has an impressive web site with several filter designs well documented. I chose other way, please look at http://www.herostechnology.co.uk/ <http://www.herostechnology.co.uk/> The assembled SCR Preselector will available in a few weeks time. I do not have prices yet, I am waiting for quotation from new providers. I am fighting to improve its price. Just I upload the SCR Preselector block diagram at Files section. The article about featured in QEX will be available at my website as soon as I get permission from ARRL. Regards.
