1) CW keying can be accomplished from the same port as CAT
(I prefer to use LPT ports and also use the N6TR PTT, and
keyer paddle inputs)
2) Yaesu FIF-232 does not include CW keying (sold one w/FT-980)
3) Have built numerous variations on the level converter theme
a) old 1488/1489 requiring dual polarity supply
b) MAX-232 with single 5v supply
c) 2 transistor with no supply required
d) combinations of above
4) Homebrew level converters worked with FT-990, FT-890, FT-736,
FRG-9600, Icom versions for R-7000 and IC-706
5) Wired CAT interfaces are available from many sources these days
6) Likewise for CW keying (e.g. LTA has CW w/paddle input and
DVK output for LPT port at $45 303-565-9950), but I built my own
7) Common LPT port pin assignment are available on my www pages:
http://www.primenet.com/~ke7gh
8) Can supply simple schematic(s) on request for CAT
9) I am GLAD the FT-1000MP has builtin RS-232, new trend I hope!
Let me know if I can be of further assistance, ke7gh@contesting.com
>>I'm thinking about purchasing the CAT interface for use with a FT-900.
>>Will the interface key CW when I'm using CT or TR? Or do I need a
>>separate interface for that?
