Re: [Elecraft] Elecraft / IC-7610 comparison

[Eric Swartz - WA6HHQ, Elecraft]

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.

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

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.

Re: [Elecraft] Elecraft / IC-7610 comparison

[Brian Denley]

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).

[Elecraft] AX1 first contact

[W1GO (Joe) via Elecraft]

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.

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

Re: [Elecraft] Elecraft IC-7610,

[Charlie T]

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?

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

Two hots (phases) and ground is three wires. Single-phase power normally
comes into a building in North America as two phases and a neutral. We
connect a 240V load between the two phases, and a 120V load between one
phase and a neutral. It's not unusual to feed a sub-panel with both
phases, neutral, and ground so that the panel can feed both 120V and
240V loads. The key here is that loads must NEVER be connected between a
phase and ground, ALWAYS between phases or between phase and neutral.

You probably know that EU runs on 230/240V, wired phase, neutral, and
ground.

Re: [Elecraft] Elecraft IC-7610,

[Grant Youngman]

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 …

Re: [Elecraft] K4 screen material?

[Wayne Burdick]

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.

Re: [Elecraft] K4 Observations

[Buck]

I heard that as well.  Elecraft's modular construction will allow for 
component upgrades as it did with the new synthesizers, thereby 
extending the useful life of the radio a couple of generations.

As an electrical engineer whose major was "power" (back when it was actually
taught) I would agree wholeheartedly.  The "2 hot plus neutral"
is most often a single phase of a three-phase delta 240V secondary with
tapped center as "neutral".  It could not be two phases of a wye because the
voltage from phase to phase would then be 208V for 120V phase-to-neutral.

Re: [Elecraft] KTCX03-1 high stability reference oscillator

[Bob McGraw K4TAX]

I ordered my K3S with the optional KTCX03-1-F which the description 
shows "1 ppm f/w correction to 0.5 ppm, factory installed".


In 3+ years of use, I check the calibration on a monthly basis. I find 
it to be always better than +/- 1 Hz at 10 MHz.   I have adjusted the 
Ref Osc as needed.  I find it to  be well worth the addition.

At 28-MHz 5ppm = 140 Hz, 1ppm = 28 Hz, 0.5ppm = 14 Hz

I installed the EXREF on my K3 with an external OCXO 10-MHz standard.
At 28-MHz  I measure +/- 1.5 Hz (counter toggles between 1-Hz and 2-Hz

Since I operate digital eme on frequencies up to 10-GHz this is useful.

I installed the EXREF on my K3 with an external OCXO 10-MHz standard.
At 28-MHz  I measure +/- 1.5 Hz (counter toggles between 1-Hz and 
2-Hz offset) with the TCXO03.  It would be 7.5 Hz using the TCXO01.


Since I operate digital eme on frequencies up to 10-GHz this is useful.

[Elecraft] KX3 & MORTTY: How to?

[Eric Rosenberg]

I'd like to use MORTTY with my KX3 (driven by Win4K3 or N1MM), but can't 
figure our how to do it.


It appears that I have to turn the KX3 keyer off, but that doesn't seem 
possible.


I'm using the MORTTY CW sketch and 3-pin connectors (tip=CW; 
ring=PTT;Sleeve=rig ground)


If it isn't possible, is there a way to drive the KX3's internal keyer 
from a keyboard (i.e., laptop).


Any help is appreciated!

73,
Eric W3DQ

I would guess that once a better preforming A/D becomes available and
affordable, a plugin upgrade will be available to replace the current A/D,
similar in concept to the synthesizer upgrades in the K3.

[Elecraft] K4 screen material?

[W0FK]

Hopefully the K4 screen be made of gorilla glass or similar scratch/damage
resistant material that’s still touch sensitive. One that is relatively
“fingerprint resistant” would also be great.

[Elecraft] Elecraft K4 NG7M YouTube Q&A Video with Eric Swartz WA6HHQ @ Hamvention 2019

[M. George]

I cornered Eric Swartz WA6HHQ for a few minutes Sunday morning and did a
quick Q&A on the K4.  ~7 minutes on the video from Sunday morning @
Hamvention 2019 .  His
comments on full-duplex / SO2R in a box were interesting. It appears that
full-duplex isn't out of the question for the K4.  Eric gives a quick
overview of the three different version of the K4, K4 HD and the K4 HD with
the Superhet module, plus touches on several other topics based on my
random questions.

Hi Wayne

Could you respond to my other questions on bandpass filters?

Thanks

Re: [Elecraft] K4 integration with N1MMLogger Spectrum Scope

[Luis V Romero (mobile)]

I believe that the remote spectrum feature in Logger+ works with a data stream 
output via the USB connection. Logically, this means that the RADIO has to be 
able to send the data stream to form the remote spectrum display. 

The HDMI output does present an independent from the front panel display of the 
recievef spectrum data, so there is some hope that this capability exists, at 
least inside the radio. 

The remote spectrum display in M1MM Logger + is a really helpful feature, so it 
would be great to have this without additional wedgeware to make it happen. 

The fact that there is a Linux core to this radio is encouraging from a feature 
development perspective. 

As the President of my former employer used to tell clients at trade shows 
“yeah, that feature you want in the system is only a couple of lines of code”.  

True famous last words, those ... Literally!

Oh dear Elecraft..

You should not be shipping US power corded equipment to Europe (or I
suspect anywhere else outside the USA!)

If it was purchased through a local dealer, "they" should have removed
the US spec' cord, and replaced it with a EU (or other local) spec'
power cord, and also possibly PAT tested it.  (Electrical safety test,
relating to insulation and safety ground integrity for all exposed
metalwork and connectors.)

Do they also comply with the EU "Low Voltage Directive" in regards to
Power Factor (Line current distortion) vs the power drawn from the
supply I wonder?   If thy just have a transformer/rectifier/capacitor
type supply, the answer will be no.

If using a bought in SMPS, then maybe, but the SMPS makers data will
need to be examined.

Transformer Rectifier Capacitor type PSU's for "non industrial" use are
largely outlawed over here for such high power applications these days.

Regards.

Dave B G0WBX.

Re: [Elecraft] K4 bandpass filters?

[Nr4c]

The K4D has s second ADC and therefore must have the band pass filters 
identical to the existing ADC use for the main two receivers in the base K4.
