Thanks, Chuck for bringing the technical issues to the forefront. I emailed the fellow directly, and here's his reply:
Dear canswl, Good evening Gentleman ! I am using binocular ferrite cores for my transformers. The material I use closed to 43 material . It has permeability of 850 .That permits me to bild matching trasformers to frequencys 1.7 to 27 MHz. My goal is - to let my customers experiment on a different bands .... For MW I would use iron powder toroids with permeability of 10-40 ...I have such toroids but was using them only for 160 meters applications and stoped to do that ... Termination resistors I use are metal film resisotrs . After long experiments I use russian 2 watt MLT-2 resistors . These resisotrs has 5 times overload ability and has very small reactive resistance in values range untill 500 OHm - due to their specific construction .. I have adjustable termination resistors as well . We just moved to Canada and retuning to the business step-by-step . 4 BV antenna remote switches , bi-derectional BV , EMI coax arrestors , SDR receivers ,preamplfiers and other Low Band DX-ing gear will be available on eBay very soon ... You can try it . I sold my gear to almost 40 countries ... It's just works . Regards ! Alex - kafa2500 Looks like he's very accommodating for our needs. Being so close, I might just have to pay him a visit sometime and see his line up! ......Walt ----- Original Message ----- From: Patrick Griffith <antennawiz...@hotmail.com> Date: Monday, September 6, 2010 18:40 Subject: Re: [IRCA] Beverage antenna kit To: IRCA <irca@hard-core-dx.com> > > Very good points Chuck.
