Configuration Questions

[W1KSZ]

I am putting together my list and have some questions:

1) Does the stock K3/100 come with any filters ?

2) If I buy the Second Receiver (KRX3), do I need KXV3A ?
I do have receiving antennas for 160 & 80.

3) Can I connect an external monitor to the stock P3 or
will I need an optional VGA/DVI/HDMI port ? Which of
these 3 standards do you get ?

Thanks for any help,

73 es HH, Dick, W1KSZ

The 2.7 5-pole roofing filter comes with the K3 if you don't order the
2.8 KHz 8-pole.  One of these is required for a basic K3.

You will need the KXV3 if you'd want to use a separate receive
antenna.  You might want to consider the KXV3A if you ever plan on
buying the K144XV 2m internal transverter.

You would order the P3/SVGA option for the P3 for an external monitor
connection.  The stock P3 doesn't support this.  The P3/SVGA supports
an external SVGA monitor.

Good luck with your decision.  IMHO, you can't go wrong.

1) The K3 normally comes with a 2.7 kHz 5-pole filter. If you prefer a 2.8
kHz 8-pole filter instead, you can substitute it for the 2.7 5-pole by
ordering KFL3A-2.8_2.7sw at initial purchase.
2) You'll want a KXV3A for its Rx antenna connection. A KXV3A (IF out) is
also needed for the P3.
3) A P3SVGA is needed for an external monitor. It supplies an SVGA output.

Yes. First, understand that IF filtering is done in DSP. Plug-in filters
are ROOFING filters. One such filter comes with the stock radio -- 2.7
kHz, 5 poles, and that filter is also the TX filter. Additional filters
are important only if you're a contester -- they protect the DSP IF from
strong signals that could blow it away, and they also cascade with the
DSP to provide steeper slopes. I have 250 Hz, 400 Hz, and 1.8 kHz
filters in my K3s. I find the 1.8 kHz filter a bit narrow for SSB, and
recommend 2.1 kHz instead. For CW contesting, I mostly use the 250 Hz
roofer. Many are happy with the 400 Hz filter.  Filters are easy to add
later -- IF you don't have the 2nd RX installed. The 2nd RX is a real
"shoehorn job" to install and remove, so I suggest that you figure out
what filters you want before you buy the 2nd RX.  If you're going to do
diversity, you what the same narrow filters in both RX.

You want the KXV3A. I don't remember why. :)

No. The primary advantages of the SVGA display board is that 1) it
provides greatly increases frequency resolution in that external
display; 2) it can display a much longer time in the waterfall; and 3)
you can plug a USB keyboard into it and use it to send RTTY and PSK both
from the keyboard and from a bunch of memories; 4) the VGA displays up
to four lines of decoded RTTY, CW, or PSK.  This is a quite nice feature
-- decoding is done in the K3, and the decoders are quite good. I find
the K3 RTTY decode generally better than MMTTY. I don't work PSK.

I strongly recommend that you buy the K3 and accessories as kits. You
save a bunch of money, assembly is easy, and you'll know a lot more
about the rig. I've built two K3/100s. First one took about 11 hours,
second one an hour less. 2nd RX is another 4-6 hours. My mechanical
skills are modest, and some build faster.

If you're going to run barefoot, you want either the 100W tuner or the
KAT500. The KAT500 is good for 1kW with reasonably well matched antennas.
