[Elecraft] K3 sub-receiver usefulness?

"At this point, I’m ready to purchase 2 general coverage modules plus 2 each
of the following filters: 250KHz, 400KHz, 2.8Khz, 6KHz, 13KHz."

Yikes...nearly $1500 in filters and BPF modules alone!  I strongly agree
with you John.  I cannot fathom why anyone would order both the 400 and
250...much less two each.  There's only 65 Hz difference in actual 6 dB
bandwidth (435 versus 370) or ~18% between them.  At least consider the new
500 in place of the 400.

At this rate Eric and Wayne will soon be flying their new G5 to hamfests and
Inrad will be listing on the NYSE.  :-)

73,  Bill
