Hello,
this is not good for K4. These products are thought to be manage by
operative systems and drivers (like Windows or Mac or Linux), this is
not the case of the K4 that have a custom "OS" and can't manage that
kind of devices.
Maybe you can use more complicated and expensive devices thought to be
used with RJ-45 ports, where this device use a DHCP and give an ip
address to the RJ-45 port creating a private network between the RJ-45
and the device, afterwards the device can access the WIFI network with
his wifi adapter and work like a bridge between the two network. In this
way, maybe, you can connect the K4 to the wifi in a more "natural" way.
Like this one for example:

For less than $10 you can buy a little WiFi adapter that plugs into a
USB port. For example:

When you mention that the K4 has Ethernet (which means cables to me),
it must also have WiFi if you can control with tablets, no?

OK, So why should I [pejorative deleted] my IC-7610 for a K4?
Hi Charlie,
The '7610 is an impressive and capable radio. We have one in our shop
and have put it on the air.
It's a bit of apples/oranges comparison to the K4, though. Since you
asked ... here are some K4 characteristics to consider:
* Controls -- The K4's UI is quite different, borrowing heavily from
the K3, but with an infusion of versatility due to the 7" display. It
has the widest available viewing angle and is very bright. (K4
tire-kickers at Dayton were extremely complimentary about the
display, which was gratifying after 200 or so iterations on the
concept drawing by yours truly.) There are three multifunction knobs
(not just one), each mapped to a semantic group, e.g. "XMIT". Their
functions adapt to the current operating mode, etc. On the right side
of the radio there are three 400-count, ball-bearing drive optical
shaft encoders, for VFO A, VFO B, and RIT/XIT offset. No need to
multi-task one or two controls. Bottom line: ease of use. If you do
get stuck, there's a built-in help system.
* Dynamic range -- The K4 is a direct-sampling, dual-receiver radio
in its base configuration. But those in high-signal environments can
add the dual superhet module to realize a 20 to 25 dB improvement in
headroom (blocking dynamic range) over any radio that is
direct-sampling only. This is the same delta as, for example, a K3S
vs. any other non-superhet on Sherwood's list.
* Portability -- The K4 weighs only about 10 pounds, draws only about
2 amps on RX, and can run down to 11 volts. It will try to drag you
off to a Field Day site or remote island if not bolted to your desk.
• Remote control -- The K4 comes with remote-control via Ethernet
built in. One K4 can controlled by another, or by a tablet or PC.
Eric must have demonstrated this 500 times at Dayton and I daresay
he's getting good at it.
* Modularity -- We segregated the K4's modules in such a way as to
facilitate easy update to units in the field if/when new tech becomes
available. For example, we could quickly and cost-effectively
incorporate a new ADC or DAC. Call it planned non-obsolescence. This
the 20th anniversary of the K2, and the 10th anniversary of the K3.
Both are still shipping.
* Extensibility -- In addition to the HDR module, the user will be
able to add a VHF/UHF module, which in turn could morph in the
future. This philosophy extends to software as well, given the K4's
general-purpose computing module [not Windows]. I like to think of it
as our "app engine," limited only by the imagination of our software
team and other talented contributors.
* External monitor output -- HDMI, not DVI. (To each his own?)
* Tuning aid -- The "mini-pan" is one of our favorite features of the
K4. When you tap on a signal you don't just get a geometric
magnification of the main panadapter's pixels; you get a re-sampled,
high-resolution spectral display of as narrow as +/- 1 kHz (varying
per mode). This is great for signal auto-spotting and left/right peak
search. The mini-pan is per-receiver and can either be turned on
automatically or by tapping either S-meter.
• IO -- The K4's IO is a superset of the K3's, meaning it comes with
all of the analog and control I/O you might need as well as 4 USB
ports, Ethernet, etc.
* Antenna sources -- There are up to 3 ATU antenna jacks and up to 5
receive antenna inputs.
73,
Wayne
