Hello I ordered mine all ready built he is not answering my questions either I don't think this can even go below 2.1 mhz either is your kis all ready built? I am visually impaired and am unable to sodder at this point. am reading articles on how to sodder but at this point don't know how to yet Hank ----- Original Message ----- From: "larryw8er" <robi...@roadrunner.com> To: <soft_radio@yahoogroups.com> Sent: Monday, January 25, 2010 9:12 PM Subject: [soft_radio] Re: LD-1 Discussion on Garage-shoppe.com Blog
