Re: [Elecraft] KX2 on JT65 & JT9 ??

[Wayne Burdick]

Lyle is on vacation and didn't get that memo. He's above and beyond the call of 
duty posting at all :)

Also note that the latest production KX3 RF board (rev. E) has the synth 
circuitry a lot farther from the PA and driver. This significantly reduced the 
thermal gradient. (The other major Rev. E RF board improvement was tighter 
17/15/12/10 meter band-pass filters. These were inherited by the KX2 as well.)

[Elecraft] Audacity recorder with Xonar U& & NaP3

[Dave Blaschke, w5un]

Is anyone here running their K3 with LP-Pan, NaP3, and  Xonar U7 sound 
card? I am attempting to make Audacity work with this scheme, but am 
unable to get it to record.

[Ross]

Thanks for the comments.
The Microham is the Keyer II.
I have connected the line in,line out and the usb cable to the pc, are there 
any other connections I need to make??

Yes the multicore cable from the k3 is the one for the k3 it is marked k3.
Thanks

Next to try and set up the microham for digital work.


Which microHAM Interface?

In general, set the K3/K3S to DATA mode and select MENU:MIC SEL =
LINE IN, set Mic Gain (LINE) to about 15 and configure the microHAM
interface audio levels as documented in the "Setting Audio Levels"
section of the microHAM Users Manual.  As a final "touch up" adjust
the K3 "Mic Gain" for four bars of ALC (the fifth bar can flicker).

Such data would be very beneficial.

Re: [Elecraft] KX2 on JT65 & JT9 ??

[Lyle]

The local oscillator design of the KX2 is very different from the KX3, as are 
the thermal isolation of the oscillator from the PA and the high current paths 
in the radio.  There is as yet no field temperature compensation procedure 
available for the KX2 nor is it clear that one is needed.  At least one  KX2 
field tester operated JT65 successfully with the KX2.

There are enough KX2 radios in the field now that it should be a simple matter 
for an owner to measure the stability of the radio in this mode and report the 
results to the group to satisfy the curious...

===
Actually, frequency stability is the key issue with JT65. The transmit
frequency can not drift more than about 8 hz during transmission, or the
receiving station will probably not be able to copy. It was this exact
issue that led to the development of the temp compensation scheme for the
KX3. The point of the original question was to determine whether or not the
KX2 needs such a compensation routine, or is stable enough as shipped.

If you run a KX3 without the compensation you may think they can't hear you
when actually the problem is in the small drift in your transmit frequency.
I first discovered this when running WSPR on the KX3 and listening to
myself on a nearby K3. The graphic display of carrier frequency offered by
WSPR made it clear what was happening. My stock KX3 drifted by about 14 Hz
in the first half-minute or so of transmission. Contacts on JT65 were not
impossible, but they were rare, as were WSPR reports.

You can search the archives for many, many posts on this subject, and look
on the Elecraft website for the recommended fix, which involves putting
your KX3 in the fridge, then running a compensation routine while you warm
it up with a heat gun.

Meanwhile, I would be interested to know the answer to the original
question, as I am sure many others would be as well.

Re: [Elecraft] KX2 on JT65 & JT9 ??

[Michael Walker]

The moon bounces around and causes some pretty good doppler.

Good thing that JT65-HF also has AFC built in.

http://www.packetradio.com/pdfzips/jt65-hf-setup.pdf

*AFC enables automatic frequency control and will attempt to follow a
signal that exhibits drift. Its original intent is to compensate for
Doppler shift when using JT65 for EME contacts, but it has application on
HF as well. Not for Doppler shift compensation, but for stations who show
VFO drift.*

The biggest problem is clock drift, not RF drift.

Regardless, the beta testers claimed the did JT65 without issue.

Re: [Elecraft] K3 and Signallink next the Microham

[Joe Subich, W4TV]

> Next to try and set up the microham for digital work.

Which microHAM Interface?

In general, set the K3/K3S to DATA mode and select MENU:MIC SEL =
LINE IN, set Mic Gain (LINE) to about 15 and configure the microHAM
interface audio levels as documented in the "Setting Audio Levels"
section of the microHAM Users Manual.  As a final "touch up" adjust
the K3 "Mic Gain" for four bars of ALC (the fifth bar can flicker).

[Elecraft] KX3 Auto Power Off suggestion

[Thorpe, Jeffrey]

Just a suggestion for an upcoming firmware update:

How about allowing an auto power off more selectable than 20 minutes or less 
(plus infinite)?

Sometimes I need to leave, and while I am recording to my tablet, I'll be gone 
for a few hours, coming back to everything dead (batteries in both).

Being able to select up to, say, an hour, would be good (for me at least).

Just a stab in the dark Have you selected the correct audio input 
for digital mode on the menu?


My K3s has the built-in USB sound card, so I don't know what menu 
selections are available without one.


Are you sure the SignaLink is producing audio? Have you listened with 
phones plugged into its monitor(?) jack?

Re: [Elecraft] Strong Rd feedback in mh3

[Edouard Lafargue]

  Thanks everyone! Good advice. Now that I have better Internet access
again (btw I meant "RF" not "Rd" in the subject line, of course), I
discovered this article on ... elecraft.com :
http://www.elecraft.com/Apps/eliminating_tx_rf_feedback_probl.htm   :-)

   I will experiment with less random lengths for my random wires, and
better counterpoises, and a small balun if necessary.

[Elecraft] K3 and Signallink

[Ross]

I have just checked my K3 again after a couple of months not using it, and I 
have a problem with the Signallink.
Yes I know all the comments about it, but I want to get it going before I try 
to instal the Microham keyer.
On transmit the Signallink is working perfectly, it produces the output and 
keys the k3, but I cannot get any audio, the line in and lineout plugs are in 
the correct positions on the k3.
So can someone please guide me as to what could be wrong, would it be the 
settings on the k3 or something else.
(I have checked 2 digital programs with the same result, transmit is ok, but no 
audio coming through.)

Thanks

Re: [Elecraft] KX2 on JT65 & JT9 ??

[Michael Walker]

Dan

Issues with not being able to communicate with JT65 have nothing to do with
frequency stability.  It has to do with just not being heard.  :)

Like all other digital modes, you require Transmit and Receive Audio and a
PTT line.

I would be very very very surprised that a KX2 can't handle JT65.  JT65 is
does not require a super stable transmitter.  In fact, when they use it off
the moon, there is significant doppler going on.

Re: [Elecraft] KX2 on JT65 & JT9 ??

[Michael Walker]

I don't believe that JT65 frequency stability at HF frequencies will be an
issue.

The documents say that the JT65 bandwidth is pretty generous.

I've run JT65 on  my Softrock without issue.

Re: [Elecraft] About to give up

[Phil Wheeler]

Not new so far as I know, Jim. I've been doing 
that with usb audio devices for some years.


But I must admit I've never operated WSJT-X. And 
when I use PSK31 I use Windows, due to the wider 
availability of ham radio software. My shack 
operating computer is an old 2010 11" MacBook Air, 
chosen because I can see my rigs with it in front 
of them and it has full-size keyboard. It's 
dual-boot OS X 10.11.5 and Windows 10. I do all my 
ham radio work on the Windows side. And for PSK31 
I use Digipan (which I've been using for many 
years) and a Signalink USB.


When I get a chance I'll try fldigi on the OS X 
side with the Signalink USB and see if I run into 
any difficulties of the type you describe.

Is this something new with El Capitan? I’ve always been making settings changes

five seconds and then the audio started coming out the iMac internal speakers. 
Wonderful. This is the same crud as what was happening before. Not everyone on 
10.11.5 is as lucky as I am, but there are a bunch of folks who’ve been hosed

By any chance have you in the past few weeks upgraded your mac to El Capitan? I

what I’ve put in the settings of either piece of software. Needless to say, 
with the audio going to the speakers instead of to the K3, it never goes into

working just fine. Havent’ had time to mess with FLDIGI over there yet, but

Re: [Elecraft] OT: Wireless stereo headset recommendations

There are a number of headsets on the market that will do the job.  What 
to look for is an inter office device that is used for remote telephone 
service.  Jabra has an extensive line up as does Panasonic.  I have been 
using Jarba for years and had very good luck.  The only problem is you 
won't find any of these that have true stereo.  You can get dual ear 
pieces but they will be monaural not stereo.  I have copied a link to 
the Jarba Web Site. They claim stereo but that isn't correct.  They are 
all monaural. You won't get stereo receive along with a mic. with 
Bluetooth either.  For that setup you will probably have to look for a 
Computer Gaming headset.  The list prices are something that will get 
your attention.  The best I have been able to do is to cruse eBay until 
something reasonable shows up.  I have been using a GN9460 for about 
three years.  It's range is in excess of 600 feet.  Very easy to

Re: [Elecraft] About to give up

I found the SignaLink USB VOX based PTT to be very reliable. 
When I am using a SignaLink, I can always know my computer is 
transmitting by hearing the relay click in the SignaLink. When I 
had it connected to the PTT of the K3, it was 100% reliable.


(I have moved to a different sound interface since. I still use 
the SignaLink with my KX3 operating portable.)

If anyone did not guess I made a typo, below (apparently fingers had 
see too many posts about the KX2).


==snip
Answer is the KX2-2M is very different architecture.  It converts
144-148 to 50-54 MHz unlike other Elecraft transverters that convert
to 28-30 MHz.

Of course I meant that ..."the KX3-2M is very different

Re: [Elecraft] [KX3] Using a Sound Card for Mic (Multiple) Input(s)

[Jim Brown]

On Sat,5/28/2016 5:45 AM, Joel Black wrote:


I currently have a Focusrite 2i2 I bought after my E-MU 0204 stopped working in 
OS X 10.11. It has two inputs and two outputs. Experimenting the other day, I 
tried using my MH3 mic on the input to the sound card with the sound card 
output going to the MIC IN on the KX3. It didn’t work. I then realized that the 
MH3 is a condenser mic and needs to be powered. The 2i2 has a “48 V phantom 
power” switch, but I am a little nervous of turning that on. I don’t want to 
let all the “magic smoke” out of my mic.


48V phantom power is exclusively for BALANCED mics wired from PRO use. 
It does NOT work with the unbalanced electret mics we use with our ham 
gear, and it would almost certainly fry them. The "bias" that we use for 
unbalanced mics fulfills a similar function, but the two methods and 
kinds of mics are incompatible.



After all of that, I began remembering an issue I had with a Genesis G59 SDR I 
built several years ago - the delay in the route from audio in to the sound 
card, the sound card input being processed by the computer, the computer 
outputting that data to the transmitter. It was quite reminiscent of my days 
operating the HEO satellites. The delay is unnerving and I have never been able 
to compensate for it other than turning off MON. I’m supposing I’ll have the 
same delay if I incorporate a sound card for multiple inputs.

Would I be better off just adding a mixer?


You haven't said what you want do do that you can't do with a mic and a 
sound card, and what you expect a mixer to do. I strongly recommend that 
you avoid a mixer. Far better to plug and unplug if you need to -- plug 
in the mic for SSB, plug in a cable from computer audio for digital modes.


BTW -- the need to plug and unplug is one of the shortcomings of the KX3 
(and KX2) as compared to K3/K3S. With the K3/K3S, you can leave 
everything plugged in.


I do NOT recommend a mixer -- too many complications with hum, buzz, and 
RFI and getting levels set right.
