[Elecraft] K3 TX Bandwidth

[Roy Morris]

I understand the present thinking is to supply the K3 with a 2.7 Khz 5 pole (standard) filter on the MAIN RX board which determines the transmit bandwidth.  Is there any other option other than the slightly wider 2.8 Khz 8 pole filter to get a wider bandwidth?  Would a variable crystal roofing filter on the MAIN RX board accomplish a bandwidth of choice?  If so, will this be offered?  Roy Morris  W4WFB
