K3S Comparison table finalized (link attached)

wayne burdick

Our detailed, two-page comparison table between the K3S and IC-7610 is now complete:

     http://www.elecraft.com/K3/K3S_comparison1.pdf

I’d like to thank everyone who reviewed the table for content and accuracy, including several who own or have used both radios. Many of your suggestions were incorporated. As a result, the table now captures those aspects of the performance, portability, and user interface of the K3S that are most important to current and prospective owners.

The table is an excellent starting point. If you still have unanswered questions about K3S features, theory of operation, etc., feel free to email me directly. (In fact, if you’re within driving distance of my QTH in Belmont, CA, stop by for a demo :)

73,
Wayne

Wes,

Max power output is automatically reduced in proportion to supply voltage. At very low voltages the PA is bypassed, but the operator can keep right on transmitting at QRP levels.

Both rigs use their BPFs in TX and RX modes. But the K3S also uses LPFs in both cases, improving IP2, etc.

I would like to see a K3 upgraded version compared to the K3S and 7610.  I have the K3 sn4629 with new Syn 2nd rx using it on MARS alot.

In reply to this post by wayne burdick
Nice document.  But it would be interesting to augment the P3 section with a
feature comparison to the Icom.  IMHO, the P3/SVGA a a natural component of
the K3S - not just an add-on option.   Thanks!

Re: K3S Comparison table finalized (link attached)

Bob Wilson, N6TV
Agreed Ken.

This is the only part of the table that seems a bit unfair to the IC-7610.
I've added the missing parts with ">>>" (I hope this formats OK):

*Features*               *K3S*             *IC-7610*    *K3S Benefits*
Spectrum + waterfall
display area           total 7.5”      5.5”       More readable display

>>> Display. res.      P3: 480x272     800x480    (IC-7610 better res.)
>>>                P3SVGA: 1920x1080              P3SVGA better res.

Marker pointing
mechanism              Dedicated knob  Touch      Accurate marker tuning
>>>                                    or
>>>                                    USB Mouse  (Mouse more accurate)


In sum, even using only part of the screen for the waterfall, the IC-7610
display may be able to use more horizontal pixels than the P3, so it can
show more signal lines.  But the Icom waterfall display doesn't scroll in
Fixed mode (the VFO A cursor just goes off screen), which is a major flaw
in Icom's design, not to mention the complex menu settings required to
adjust the waterfall span and edges.

Yes, the P3 dedicated knob + markers may be more accurate than touching the
Icom screen, but using that tiny P3 knob is really much more difficult than
clicking on a signal with an SDR, or just moving the VFO knob.  However,
the IC-7610 does let you connect a USB mouse.  Then you just click on
signals with the mouse pointer on the screen, so Icom wins on that.

However, I'm told that the scroll wheel on the mouse doesn't "fine tune"
the Icom VFO position after you click, so they really missed the boat on
that one.

Again I beg for the P3's USB connector to add mouse support.  The hardware
is all there.

Left click:        Move VFO A
Right click:      Move VFO B
Scroll Wheel:  Fine tune VFO A, B, or last-clicked (user option)

Wayne,


You duplicated the line about the ATU:


ATU* matching range @ 100 W 10:1 (typ) 3:1 Allows monoband antennas to
be used on other bands


It's in the General and Transmitter sections.


Also, I would REALLY like to be able to plug a mouse into the P3, and
click my way around the SVGA screen.  That's the one big thing I miss
from when I was using Larry's N8LP LP Pan on my PC before the P3 came
out.  It was very handy looking for folks calling CQ by just clicking
around the waterfall.  Really changed my operating experience.  Found
out there are a lot of folks out there calling CQ, but you just miss
them by randomly tuning around.


Thanks,

FW: [Elecraft-K3] K3S Comparison table finalized (link attached)

Jim N7US
In reply to this post by wayne burdick
I'd be interested in seeing a similar comparison of the K3S to the
FlexRadio.

My two cents:

radio at #1 cannot be reproduced with current software.

Clarified recently in footnote "y" of the RX performance table.


> That makes the K3S #1 and the 7610 #9 if you want to count for some
reason. The difference in 2 kHz dynamic range is 106 dB compared to 98 dB.

The table is sorted on 2 kHz IMDDR3. However, the table also shows dramatic
differences in blocking dynamic range. For example, the K3S is 20 to 30 dB
stronger in this regard than all of the direct-sampling radios in the table.
This is due to the K3S having narrow-band filtering (crystal filters) ahead
of the ADC. This can greatly reduce desense and other artifacts in any
high-signal situation (Field Day, KW neighbor, multi-TX station, etc.).

Re: FW: [Elecraft-K3] K3S Comparison table finalized (linkattached)

WW3S
and that was my real life experience in last weekends 160 contest....I felt
the 7610 could hear just a bit better than the K3, especially those ESP
signals right at the noise.....I worked several DX I wouldn’t have with the
K3.....BUT.......in crowded condx, the 7610 thumped and pumped when someone
was close to my passband, even with a 200 hz filter enabled. I didn’t get
any of that with the K3, its front end is like a brick wall......to be fair,
I had the noise blanker enabled on the 7610, which some comments post
contest said that could be some of the thumping I experienced.....

I'd be interested in seeing a similar comparison of the K3S to the
FlexRadio.

My two cents:

radio at #1 cannot be reproduced with current software.

Clarified recently in footnote "y" of the RX performance table.


> That makes the K3S #1 and the 7610 #9 if you want to count for some
reason. The difference in 2 kHz dynamic range is 106 dB compared to 98 dB.

The table is sorted on 2 kHz IMDDR3. However, the table also shows dramatic
differences in blocking dynamic range. For example, the K3S is 20 to 30 dB
stronger in this regard than all of the direct-sampling radios in the table.
This is due to the K3S having narrow-band filtering (crystal filters) ahead
of the ADC. This can greatly reduce desense and other artifacts in any
high-signal situation (Field Day, KW neighbor, multi-TX station, etc.).

Having owned both, I can assure you of one thing.
You really don’t want to go there.
