[Elecraft] Considering purchase of K4D

[Rick NK7I]

The highlights are:

1)

  * A MUCH quieter receiver (the BEST CW rig I've used over the past
    almost 50 years);
  * Better overall performance;
  * It is a living growing product (some things, still being fleshed out
    or developed)
  * Ability to manage via one real serial port, 2 USB com ports or
    unlimited via IP _all at the same time_.
  * It will only get better over time;  the K3 is a 'dead end' line
    (that still works VERY well) it has reached it's limit;
  * You can get parts and add ons for the K4;
  * It has ability to be run by it's internal or external macros (HUGE
    flexibility option);
  * Native 1GHz capable network, in place;
  * Simpler overall interfacing for specific station needs (antennas,
    transverters, switches);
  * Simpler remote operations, including K4-K4 without a computer and
    VK4 on laptops, tablets and phones (shortly).

Noise reduction and noise blanking, is one of the works in progress 
(remote operations topped 'the list').  While adequate for me now (I'm 
rural but with some power lines, electric fences and other rural 
'things'); it could be made better.  The quieter receiver does help make 
weaker signals heard, most of the time even with the noises of farm and 
timber lands.

2)

  * Because Rob Sherwood (and he has clearly stated) only saw one K4
    with the earlier firmware versions and it is MUCH improved now (and
    still in progress).  If you read the rest of Rob, it's not about all
    of the numbers, but a compilation of MANY factors (mostly UI like
    menu and knob access).
  * An updated evaluation can be done IF someone is willing to loan (or
    buy) a K4 for Rob for testing (takes xxx weeks, he's thorough).
  * One does not judge the performance of any living line, on the first
    model (i.e. the Mustang, Corvette or Camaro); things get better
    (it's no Pinto or Edsel).
  * There is one likely near you; seek it out and ask to see it play (or
    watch some videos online).

Is the K4 perfect?  Not yet but my very well dressed K3/P3 sits in a 
storage box (next to other bygone gear).

Is now the right time to buy?  Yes, there is a sale until the end of the 
month (or buy used but be QUICK about it once posted, seconds count) and 
the prices won't get much better.

To install my K4, I pulled the K3/P3 off the desk, reconnected 
everything to the K4 and was up and running in minutes (excluding some 
software changes of course, mostly port settings and audio levels).

I'm no shill and I have no issue in being direct.  I liked the K4 so 
much that I bought a second for chair two or as backup should the need 
ever arise.  (Station growth never ends.)

Most of the default menus items were 'ok' and over the next couple weeks 
were adjusted to my operating preferences (DXing) and local conditions.

K3 to K4 transition is not a steep learning curve; but they are two 
different rigs, there IS a curve.  (Kenwood to Elecraft, slightly 
steeper.  "Other" brands, steeper again but MUCH simpler.)

73,
