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

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
