Almost! We are testing the final firmware right now. We made a few f/w
changes as a result of field tester feedback.

If all goes to plan, we should ship later this week.

In reply to this post by W7GJ, Lance
Thanks for all the suggestions!  I called Elecraft Tech Support and they confirmed
that the optional "KXSER" cable had a DB9 back that could be opened, providing access
to all the serial lines that came in on my USB to serial converter cable (I will just
use the one that I have been using on K3 when operating portable).  I will then
install a transistor switch in that connector and add a line out of that DB9
connector to the mic jack to key the rig ;-)

So, I added that change to my KX3 order and I THINK the problem is solved!  I just
need to order one of those special mic plugs and wire it with jacks for the mic and
PTT and I am in business!  TNX for all the help!  VY

Not in recent recorded history!  So-called RS-232 interfaces started
getting cheapened many years ago (before they went away and were
replaced by USB), and one of the first things to go was output voltage
swing. Think about the voltages available in a laptop, for example. I'd
be very surprised to see more than 10-12V on anything other than an
industrial RS232 interface, and less  on most laptops.

What is in the "KX3 ACCESSORY CABLE KIT" referenced in the manual and how much does
it cost?  I can not find it on the order form anywhere...Maybe I just can't figure
out where to look for it.  VY 73, Lance

Not just RS-232 either.  A few years ago I had two band decoders, and
they would work fine on one LPT port but not on the other.  Turned out
the questionable port was only delivering 3.3 volts as logic 1, not
quite enough for the band decoder.

Hi Jim,

you are correct about lower voltages on "modern" computers. Nevertheless the
specs are higher and even 10-12 V is too much for most microprocessor pins.
And I've seen a lot of ham shacks where *old* computers are still in use
that have real serial ports with correct levels (as per sprecs). So to be on
the save side we should not suggest people to apply RS-232 line levels
directly even though it *might* work with some computers. ;-))

Lance,

I apologize, but that information is incorrect. The KXSER uses a sealed
molded connector for the RS-232 connector. It can not be opened.

There are a number of simple RS-232 male-female break our boards onthe
net. You might want to try one of those. Or just make a simple short
RS-232 cable that breaks out the desired lines.

73,

Eric

Thanks, Wayne. When I first saw pictures of the KX3 I couldn't see the 7, 8,
or 9 buttons. I have found them in more recent pictures. I'm curious to
learn how to enter a frequency using 7, 8, and 9 when they are on (what
appear to be) rotary knobs rather than pushbuttons.

In reply to this post by wayne burdick
Hi,

I think the manual should list the exact pin outs for each connector in KX3 - just like given for the microphone input in the current version of the manual. Many of these might be obvious to experienced hams (like the CW key input) but may not be so to new comers. Anyway, I have question related to the I/Q output - should I use a straight stereo cable (gnd to gnd, left to left, right to right) for going from I/Q to the line in in my PC sound card? (the exact pin outs for all the connectors should be preferably listed in an appendix as a table for fast access).

Thanks,

Jussi Eloranta

Re: Elecraft KX3 Owner's Manual now available (*preliminary*)

Hi,

Forgot to also mention that the KX3 preliminary manual only refers to a
windows program (http://www.hdsdr.de) for SDR (which pretty much leaves
mac and linux users in the dark; it might work under the wine
emulator?). There are multiplatform applications, such as python based
quisk, that will do the very basic stuff. Perhaps it would be a good
idea to try to promote multiplatform solutions (or at least mention
about their existence)?

Jussi Eloranta

ps. Is there another way to provide feedback on the KX3 manual rather
than posting everything on the mailing list?
I am pretty sure that most people don't want to see these posts...
