[Emilse Peraza]

Well tahnks to everybody that has answer me, so seems like a lot of you guys use the K3 in CW what about SSB, I ma mostly interested in SSB PSK31 and some MARS, so any ideas about that aspecte compare to the jap radios

The K3 is "data ready".  What that means is that you can simply connect
two stereo cables with 3.5mm plugs between the K3 and your computer
soundcard.  Add to that an RS-232 cable to handle the PTT function and
you can operate all of the data modes.  The K3 has a DATA mode in
addition to SSB that turns compression off for best IMD.  There are 4
sub-modes for DATA mode - 1) DATA A for most soundcard data modes - 2)
AFSK A for soundcard generated RTTY (RTTY works in DATA A too, but AFSK
A adds some features. -3) PSK D (for PSK Direct) which allows you to
enter text from the paddles and it will be converted to PSK31 signals in
the K3 with decode of the received signal in the VFO B display.  That is
handy when you want to operate PSK without a computer.  Finally -4) FSK
D which can be used just like PSK D with input from the paddles and text
display on the VFO B LCD area, but can also be used with true FSK with
the input on the ACC connector.

The bottom line, you can easily use the K3 on data modes, and the
interface is built-in, no need for an external data mode interface box.  
There are transformer isolated LINE IN and LINE OUT connectors on the
back of the K3 just or this purpose (and more too).

Our VE2DXY team (zone 2) exclusively used K3 Radio's for the CQWW SSB
contest last year. Previously we had used Icom 756pro's and other Icom
radio's. Although not, scientific, and there are many factors which affect
propagation, we felt there was a significant difference in our ability to
hear and work weak stations.  We also felt that the filtration in the K3
gave us an edge in the crowded bands even over the 756pro with the IRC
roofing filter installed. If you can't hear them, you can't work them. One
of our operators who joined us this year had previously used an Icom 7800 in
the contest. He was so impressed with the performance of the K3 that he
stated he wanted to purchase one going forward.

This weekend, I used the K3 in AFSK for the RTTY contest. I used the 500 Hz
roofing filter and was able to work numerous stations, picking out stations
in a very crowded band. Previously I had used my Icom 756pro.

Once again, this is not scientific and just my opinion.

While I got the K3 for CW and digital, and still like the Mark-V for operating SSB, I find that the K3 is just as capable for SSB as the Mark-V, and maybe more capable after I learn more about setting the NR.

On SSB I find the Mark-V more convenient to operate, but it isn't really any better in performance. More creature comfort then anything else.
