[Elecraft] [K3] Filters for mixed JT65 and JT9 HF

I don't have a solution for wideband transmit (since I don't own a K3) 
but there is a simple fix: Run split.  That way, the software will keep 
the transmit close to 1500 Hz by offsetting the QRG automatically.  You 
can use the full receive bandwidth and the software will take care of 
keeping the transmit in range.

I use this on my K2 and it is great.  You just have to set it in the 
WSJT-X settings and make sure the K3 is set in split mode.  On the K2, 
split is reset each time the transceiver is power cycled so I have to be 
sure to set it back on split mode.
