WA6HHZ explained "We chose INRAD as our OEM 8-pole crystal filter
supplier because of their excellent filter performance."
I hope Elecraft will consider offering the Inrad 1.8Khz 8-pole filter
8.215Mhz if (711-B) for the K3, or even something narrower, for ssb
contesting. I assume the K3 will be able to transmit through the
stock 2.7Khz filter and switch in a narrower filter when receiving.
