[Hallicrafters] SX-28 sensitivity on 10-15 meters?

[kwylow zinjanthropus]

I suspect that the effects of mismatch are more pronounced at the higher frequencies which may lead to a procedure that calls for switching in/out the balun at the 5 Mcs point (if one chooses not to construct that lower frequency balun). O.k. I'll be toying with this phenomenon and hauling out my Ameco preamp. 73 de Cal, N6KYR.

pretty sorry below 5 MHz! The idea is good, though, and it shouldn't
be difficult to hombrew a transformer that will work down to the
lower end of the broadcast band. A lot of hams are using type 73
material binocular cores for matching beverages, K9AY loops, etc.
