The screen uses capacitive touch, like a smart phone or table. The surface is thick, long-life glass. 

Some radios use resistive touch which is less expensive. Such screens require more contact force in general and are not optically transparent.

I have not read EVERYTHING in this thread... but I sure don?t recall anyone
saying you should get rid of your IC-7610.

Maybe I missed something.

Weil .. with an Icom you?ll have the privilege and the ultimate enjoyment of eventually being sucked in by the next shiny object, and purchasing a 7610XL, and 7615, and 1715XL and ? and ?

With the E?craft, (if history is any indication), you will be able to purchase a few boards over time.  Sure,  they?re not free .. but it?s just boards.  And you may actually get software updates and new features in the ?old? radio.

But I don?t know if that means you should part with your 7610,  You can always ask the 756Pro guys what they think (?).  :-)

Clearly I?m biased ?

Jim is using the NEC terminology of "phase" meaning any hot conductor, 
not that two of the three phases are brought into service entrance.

No, you didn?t miss anything.

No one ?said? I should do anything.

However, it?s obvious to me that the K4 is basically an IC7610 on muscle building steroids and probably has an infusion of alien technology (new stuff, not the old 1947 Roswell cache).

There are features and performance that far exceed the Icom?s capabilities.

Even though, on the surface, they ?look? somewhat alike.

My question (only to myself, but rhetorically stated) is should I make the switch?

Looking for a KPA3 100-w amp for the K3.

The newer KPA3A, used in the K3-s, 
would also work.

Also looking for KPA3 parts.  A pair of

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.

All, 

First use of AX1 today in New York?s Adirondack Mountains.  KX3, CW, 20M and < 10W.  Special event station LZ497OM, Bulgaria, about 5K miles.  

Pretty amazing given the fact the station was work numerous NA and Europe stations.  Now that?s serious fun!

Happy operating.

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?

Or are you saying that you connect the K4 to your in house router through Ethernet and then access it through WiFi?  (It?s making sense to me now! Hehe).

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

Hi Brian,

Its a regular RJ-45 Ethernet jack on the rear of the K4. (I believe it is gigabit ethernet..) Usually your network router provides the wifi to connect wirelessly in the house (also including a DCHP iP address server.)

Embedding wifi in the radio is problematic as it is a rapidly evolving technology with regular changes in security features, speed etc that are best handled by router sw  and hw upgrades. Its unlikely wifi will stay constant over the radio's life.

73, 
Eric

 Yeah, the 7610 surely resembles the K4.? But how different can you make a rig with 2 vfo's and touch screen very much different looking.? Take the top and bottomcovers off each rig and see what's inside and hook each up to an antenna and see how they perform in contest condx copying some weeny teeny signal.

There is a reason the 7610 is different than a K4 and it's not only the price.? But the 7610 is a decent radio too.? It all depends on what you want sitting on your shackdesk.
Whatever tames your pileups.? The K3 is one of the best radios I have used and am glad I decided to buy it in 2009.? I've listened to a lot of radios since 1963.

No one ?said? I should do anything.

However, it?s obvious to me that the K4 is basically an IC7610 on muscle building steroids and probably has an infusion of alien technology (new stuff, not the old 1947 Roswell cache).

There are features and performance that far exceed the Icom?s capabilities.

Even though, on the surface, they ?look? somewhat alike.

My question (only to myself, but rhetorically stated) is should I make the switch?

Please stop trying to distract me.? I am trying very hard not to visualize the K4HD taking the place of my ft1000mp already sitting next to my loaded K3 with P3 (K3 purchased in 2009 serial #2995).I also replaced my manual tune Alpha with the KPA1500 (serial #153) and that combo is one of my so2r stations.? I also have the Acom2000A but that is the companion of the ft1000mp.? If I give intoseeing that K4HD instead of the Yaesu ft1k I will have to keep the Acom instead of getting a 2nd KPA1500.? I apologize, I think.

p.s.? I am still partial to tube amps though, hi, but do love my kpa.
