Hello
Thanks, Trevor for your info.
I bought 4 years ago a German ( was it a Chinese made stuff...?) desoldering
system. Worked not so well, but was somehow helpful. Needed it after a year
of non-use, and just refuses to suck ! And it seems difficult to open : no
screws, but a queer sort of clip
I completed a K1-4 about ten months ago, for 40,30,20,15. Lately am
missing 17, and sometimes 10 would be handy. This will become more evident
as we climb out of sunspot minimum. Found a note from 2006 from a Japanese
ham who converted a K-1 filter to 10 meters. Wayne had responded,
I would like to practice sending wo transmitting with my KX-1. Is there a way
to put it into a practice mode w/o using a dummy load? If a dummy load is
required can someone direct me to where I can get one?

Thanks to W0YK for goading me into RTTY. Had some social obs
that limited my available time but it was a fun first run.
The K3 worked very well, although I have no RTTY

Yes, the K3 can decode RTTY and display it on its own LCD, but I
didn't use that feature during the contest.

Yes, the current firmware decodes CW, RTTY and PSK in the VFO-B display
area. However, it is just the first pass implementation and more tweaking
and functionality is on the way. This is a great feature (coupled

Paul,
Set the KX1 to 'Keyer Test Mode' - see the manual page 66 (lower right
corner). It works for both keying and message playback.

From my perspective, those keying circuits want to be inside the radio,
safe from harm. Is there any reason why they weren't made part of the
radio - or why I shouldn't put them in when I get my K3? (Assuming of
course I can get into that part to do so...)
The K3 accepts open collector(or
As a counter to Jeff's perspective, I find that similar things which are
integrated inside the radio will slave that radio to one particular way
of providing that function. Times change, desires change, but that
radio is locked into the past because of the 'way things were done back
then'.
Paul,
Press the menu button and rotate the VFO knob until it says PLY.
Tap the VFO knob and it will say P=0 for test mode.

For a dummy load, the Elecraft DL1 would be a nice project;

Hello Jeff!
...I'm just saying this was an
opportunity to put the level shift in the radio, and I wonder why it
wasn't, and why I couldn't/shouldn't modify my own K3? thanks!
One of the modes that the K3 will use that very same data input pin for
is direct PSK in the same sense that it
Hi Jeff:
IF you do, how will you then tell the radio specific serial cable pin
to look at for CW keying/RTTY keying/PTT/etc?
If you place them, as Rick and others do, then you can create
mode-specific interfaces for your software.
IF you put them inside the rig, then THAT particular pin
hi Don - I'm confused. Open collector FSK inputs have been around for at least 20 years, probably
longer. Radios have already been slaves to that particular way. What I'm saying is let's make it
easier to get on FSK using a standard DB9 cable, and not require the user to build a special cable.
NOW I am totally confused!!!
I am not saying they will change, I am saying they were designed to
support general purpose usage. You will *not* need to disconnect data
mode cabling to operate in CW or SSB or AM or FM or...
Sorry, I should have taken this private.

Jeff:
And I'm afraid my skill set has never been up to the micro-surgery
required to build circuits inside a connector shell a much
better place for circuits is safely inside the chassis.
Please allow me to direct your attention to:

I'd much prefer to have this sort of thing external to the rig and
just use them to KEY the dedicated input on the rig.
Couldn't agree more. I think this stuff is made integral, even if barely
usable in any other than a lets see if this really works mode, to get the
blood heated up, feed the
Jeff,
The K3's I/O module already provides for the use of RTS or DTR for PTT
and/or CW KEY in (two separate control lines). The exception is FSK,
which is on the ACC connector. In the present incarnation, driving this
line from a PC requires two external parts (one garden-variety NPN
hi Wayne - thanks for the reply! I understand now what you're dealing with... the GPIO sounds like a
cool way to get several different interfaces off the back panel of the radio.
I guess I just joined the ranks of those who just can't wait for their K3 and then spew all over the
reflector
I'm mainly going to use my K3 for 6m and 2m using my recently built XV144.
However, in terms of optimising my station's performance (in this case,
thinking of removing the MMIC after the PHEMT front-end to improve the XV144's
dynamic range) I'm reliant on doing the maths based on other
Wayne,
You might want to bump up that parts count to 3 - and add a diode from
the base to the emitter of that transistor (cathode toward the base) -
protects the transistor from damage on the most negative excursion of
the RS232 signal line which can go to 25 volts negative by the RS232 spec.
I recently bought an assembled T1 tuner. I'm going to hook it up to a
homebrew dipole-like antenna that consists of 2 helically wound wires.
It seems like I should use a twin-lead line to feed it. So I supposed I
should use a balun (like your BL1).
I'm assuming I should have the balun near
For making keying interfaces you can buy transistors with the pull up
resistors built in
My personal favorites come in SMT format and are small enough to easily
build into pretty much any connector

Personally I would like to modulate and demodulate in the radio, with
the communication with the terminal (computer program) via RS-232 in
ASCII. Keying could be by a key line or by command codes via 232. Some
how, going from analog to digital to analog and back again to digital
strikes me as
Steve,
The key element in ESD protection is to have everything at the same
potential - that does not necessarily mean Mother Earth Ground, but it
means that everything should connect to a common point in the vicinity
of the work bench. The 3 wire cords are supposed to accomplish that for
OK - my experience with digital modes is really limited, so pardon me
for asking me this probably lame question.
Since the K3 has an isolated sound card interface, this will
*completely* replace the interface I currently use to run digital from
my PC to an HF rig?
I'm pretty sure it does, but
Kevin, it was tough out here in the midwest for the Sunday 20 meter net. You
copied my new K2 and serial just fine. I am near Cleveland and pleased to come
aboard. I've got K2 serial 6146 and can't forget it because of the venerable
power tube probably 50 years old or more. - regards and hope
I used a field-test K3 and an Icom ProIII in NAQP RTTY yesterday. The K3
worked well, and flawlessly, for its first major RTTY contest. I've been
using the same pair of radios this past month in the weekly NCCC Sprint (CW)
practice contests as well as a bit during IARU. Since folks are eager to
