Sam's advice is correct ... however, the FM filter is a suitable
alternative to the AM filter if you plan to do/try FM on the top
end of 10 Meters, 6 meters or install the internal 2 m transverter
at some point. Either the FM or AM filters will provide a 4 KHz
wide waterfall (200 - 4200 Hz) with the current WSJT-X software.
The high stability TCXO is most certainly not needed - drift over
one minute at HF just isn't a factor.

I would defiantly add the AM filter, works great for dual JT65 + JT9 wf
I do not have or need the TCXO, the stock K3 works fine for stability
the timing with a pgm like NTP is more of a key factor for QSO's

I am considering purchase of a K3 (I own a K2). One application is
the new
mixed JT65-JT9 HF mode. Possible accessories are:
-KFL3A-6K 6 kHz AM / ESSB, 8-pole filter (to allow full band mixed
waterfall)
-KTCXO3-1 TCXO (0.1 ppm typ) High Stability Ref. Osc. (to provide
stability especially as required by JT9)
Are these needed and reasonable choices?
