Carr's "Figure 3" (pg 6) High-Pass filter looks pretty good.
He says it has a cut-off frequency between 1700 and 3000 KHz and blocks some some AM BCB signals while passing all the shortwave frequencies.
" Figure 3 shows a design used for many decades. It is easily built because the capacitor values are 0.001 μF and 0.002 μF (which some people make byparallelling two 0.001 μF capacitors). "
