>To clarify my statements about finding the filters important:  Here, on receive I tend to use very broad-band, e-probe antenna systems that perform well over effectively the entire 0-60 MHz range.  Therefore, I am sensitive to the full range of spectrum that Hermes uses, all at once.  Most ham antennas are not so broad band in character, thus, many who use Hermes without Alex do fine when connected to their single-band or few-band antennas, as the antennas themselves provide a degree of “pre-filtering” to frequencies outside their designed operating range.
