Re: [Elecraft] MAC BOOK KX3 QUESTION

[Keith Onishi]

I am using “iMic”, an USB audio, wirh my Macbook Pro (Retina, Mid 2014) for 
sending and receiving digital mode with KX3.
This works fine, but I have to use VOX instead of PTT.

Re: [Elecraft] K3S and FT8

[Jim Brown]

Hi Wes,

By a combination of trial and error personal preference, this is what I 
settled on as soon as I started with WSJT-X. I choose to NOT use split 
because I like to have the sub-RX down on the CW segment below 50.1 
while I'm using the main RX with WSJT-X.  The trial and error part was 
that I discovered that the K3 would not TX if I sent any commends to it 
from WSJT-X.


SO -- I'm using DATA-A and VOX.  I see the sub-second delay that you do. 
BTW -- I use VOX for ALL modes, CW, SSB, RTTY, and WSJT modes. No problems.


73, Jim K9YC

Re: [Elecraft] [OT] Maintaining Sanity with Filters

What if I make a post with the same title as the one above, and don't 
mention any Elecraft model numbers in either the body or subject...


How do you make the decision to filter or delete then?  I ask not to be 
contentious, but to learn how for my own filters.  I don't want to have 
to set filters in real time for every OT post, but a general filter 
would be great.

And it works with more than this Elecraft list!  It seems many folks 
become deeply enamored in making their filters perfect.  I can hit the 
delete key for all the ones that escape my filters in far fewer 
keystrokes than what setting up perfect filters takes.  Elecraft list is 
easy ... while not adhered to religiously, many [most?] subject lines 
contain the product(s) that the post pertains to.

Re: [Elecraft] MAC BOOK KX3 QUESTION

[Barry Baines]

Gerry:

Please see the following link that describes what the 2010 MacBook Pro laptop 
line features:

http://www.everymac.com/systems/apple/macbook_pro/macbook-pro-unibody-faq/differences-between-macbook-pro-13-15-17-inch-mid-2010.html
 


You don’t mention whether your laptop is a 13”, 15” or 17”  MacBook Pro. 

However, depending upon the laptop type you have, the audio input/output 
features vary.  From the link above:  “However, the 15-Inch and 17-Inch models 
have optical digital/analog audio in/out and the 13-Inch does not — it lacks 
optical audio in and instead has the same combined optical digital 
output/headphone out (user-selectable analog audio line in)” port used by the 
iPhone.”

Depending upon the model laptop you have, you can either use the ports that 
Apple provides on your laptop, or you may elect to use a USB plug-in 
audio-to-digital converter.  I highly recommend the Griffin “iMIC” which can 
easily be used by both Mac OS 10.x devices as well as Windows devices under 
WinXP, Vista, Win7, Win8 Win10, etc. They’re highly reliable and the drivers 
for iMIC are integral in both Mac OS 10.x as well as Windows OS.  

Once the system recognizes the iMIC, you can easily configure whatever program 
you’re running to use the iMIC for audio input/output.  The iMIC has the 
ability to handle both ‘level-in’ audio as well as “Mic-In” by means on a slide 
switch.  Audio input is via a 1/8” jack and audio output also has a 1/8” jack.  
 It comes with a Dual female RCA -to- stereo 1/8 plug that is inserted into a 
1/8” jack.  

See:  https://griffintechnology.com/us/products/audio/home-audio/imic 



I’ve been using these devices for years at remote sites to input audio into a 
variety of computers utilized to provide an audio feed at receive sites that 
are fed to Radio Reference as well as to provide feeds from receive sites for 
railroad signal data (ATCS).  However, my experience with iMIC has been 
primarily with PCs.  I have not tried using an iMIC with Elecraft software nor 
with amateur digital programs such as JT-65 on a Mac.  That said, I don’t know 
any reason why this approach wouldn’t work for you.

Last comment: For some reason you sent your e-mail typed in CAPITAL LETTERS.  
For many e-mail users, typing in capital letters is the equivalent of SHOUTING 
which can be annoying to read. I don’t think that was your intent, but be 
mindful that others may misinterpret your postings if you use capital letters 
all the time.

Hope this helps,

Barry Baines, WD4ASW

Re: [Elecraft] MAC BOOK KX3 QUESTION

Apple has dropped audio input on current Retina MacBookPro products.  I’m not 
sure when that transition took place, and am too lazy too look :-)

There are inexpensive USB audio modules that will support both input and output 
and perhaps save you some hassle.  It’s worth checking out this link if you

I suspect that your MacBook Pro does have an audio input. If there's not
a separate mic connector, then the headphone connector probably provides
a mic/line input on a 4-conductor TRRS connector.

Re: [Elecraft] K3S Kit issue - Does not transmit in SSB

[Don Wilhelm]

For DATA modes, use DATA A and set the data mode MIC SEL to LINE IN - if 
you try to use SSB with MIC+LIN you will end up transmitting voice as 
well as data through the live mic.


With the USB connection using the internal K3 soundcard, make certain 
nothing is plugged into the 3.5mm LINE IN jack.


Adjust the soundcard slider and the MIC GAIN (now LINE IN gain) to 
produce 4 bars solid on the ALC meter with the 5th bar flashing.

Adjust your desired power with the power knob.
Ignore the internet advice to adjust the power with the audio level, it 
does not work well with Elecraft gear.

These (below) are correct.

In theory, we're all "trained" on this process, because getting off the

you get a confirmation E-Mail, and you click on the link.

Were you running a pre-recorded message on button 1 (the PRE button)?

If you forgot to tap the MSG button first before you tapped button 1, 
then the PRE function would be operative, not the message-play function.


Have done it myself.

First time I thought I bumped the switch but it actually did it 2 more times. I 
was running 5W cw to a magloop carefully tuned to resonance as best I could 
tell. I’ve used this same setup a bunch and never had that happen before-any 
thoughts? Thanks.

Re: [Elecraft] K3S and FT8

[Wes Stewart]

Fake it just moves the A VFO before transmit (if needed) and back for receive.  
The delays seem just a problematic.

Changed over to "fake it" for the split operation setting, and it

success. I suggest setting "Settings->Radio->Mode" to "None" and setting
the rig to USB-DATA-A sub-mode manually on both VFOs, as a test to see
if things speed up for you."

I tried his suggestion and didn't see much change, then I decided to turn

Re: [Elecraft] K3S Kit issue - Does not transmit in SSB

[VE8EM]

I would like to say thank you all for your answers.   The BIAS was the issue
for the MH2 microphone, I am able to transmit SSB now but somehow I am still
having issue with the computer connection... 

I guess I will keep trying things out.

The menu option for MIC SEL is now showing front port and BIAS. It works! 

The following option MIC+LIN I believe should be on to use both, am I
correct? 

I am still unable to use the internal sound card line in however...  I'll
keep trying!

Thanks!

Re: [Elecraft] KX2 preamp

[Randy]

Interesting Dan, I had a similar experience both with the KX2 and the 
lousy conditions here in eastern PNW (northern ID).  I was sending CQs 
with the MSG key then the "1" key.  Once the radio got real quiet and I 
saw that the preamp was off.  I think what happened was that the MSG key 
did not get pressed, although I thought I had done so, then when I 
pressed the "1" key, it was really the PRE key.  That turned the preamp 
off.  At least that is what I think happened.


Also thanks for the Q.  I didn't get very many of them so each was 
particularly memorable.

[Elecraft] KX3 and KPXA100 For Sale

[David Gow]

I purchased these units new and factory assembled in August of 2015.  They
have been lightly used in my  interior shack, basically for familiarization
purposes.  I had planned to use them for portable and mobile use in an RV
but our plans have changed and we will not be acquiring an RV. in the
foreseeable future.  The KX3 has all the internal accessorizes except the
two meter and 70 cm modules.  It comes with the key paddles available at
the time and the MH3 hand mic.  Both are in perfect operating condition,
look like new.  They include all cables including the adapter cable from
the KX3 to the KXPA100. so that the pair acts as a transceiver.  They are
running the most recent firmware.I am asking $1000 for the KX3 and $760 for
the KXPA.  If you buy the pair it will be $1,700.  Shipping in the
continental US is your responsibility and they will be shipped in the
original factory packing.

Please reply off the list.

Re: [Elecraft] KAT-500 brain trust question

[Chris Tate - N6WM]

John,

About 2 hours after I posted this on the reflector (on a Sunday no less), I was 
contacted by the firmware engineer agreeing with the need for this feature. 
This is also the engineer working on the KPA1500 that will have said bypass 
feature with even more granular focus than just the band, and it was his hope 
to roll some of those feature enhancements into the KAT500 downstream after 
completion of the KPA1500 code.

This is remarkable customer support and a real testament to the culture at 
Elecraft that as we all have come to know is best in class.

In the interim we have a temporary fix that works and something to look forward 
to in the future.

So apparently there is a way to automatically bypass the tuner on some
bands but unfortunately the lighted switch does not indicate this. Many
people have monoband beams (or a SteppIR) with a near perfect match on
10-20m and may only need the tuner for a couple of bands. I would also
like to have N6WM's feature request. I wonder how the KPA-1500's tuner
handles this?

Don thanks for this, indeed this is the current solution.  Although it is
rather obscure as far as indicators on the front panel.

I would like to convert this to a feature request, as It would be nice if
the firmware supported, and there was another matrix in the KAT500 Utility
that would permit a hard bypass with indicator on a per band basis.  Gives
that warm fuzzy its doing exactly what you want..

E.g. qsy to 20m.. bypass light comes on..

Re: [Elecraft] K3S Kit issue - Does not transmit in SSB

[Don Wilhelm]

Etienne,

A frequent problem is that the Bias is not turned on when using the MH2 
microphone.  It is an electret microphone and needs bias to produce audio.


As for your DATA mode operation, are you using DATA A mode?  You should be.
Do you have the mic select set to Line IN?  If not, that can be the 
problem.  Do you have anything plugged into the K3S Line IN jack?  That 
overrides the Line IN for the internal soundcard.
Do you get any indication on the ALC meter - you should set the audio so 
you have 4 bars solid with the 5th bar flickering.  You may need to 
adjust both the computer soundcard speaker or line Out sliders and the 
K3S mic gain (actually Line IN).


73,
Don W3FPR

Re: [Elecraft] K3S Kit issue - Does not transmit in SSB

[George Thornton]

I would start by bringing your tests down to the basics and eliminating any 
possible computer software configuration cause.

I would first re-load the firmware and re-run calibration.

Assuming those all work correctly, the next issue is to properly configure the 
microphone settings.  There are several things that have to be correct, 
including where the microphone is connected (rear or front), the nature of the 
microphone, any bias and the proper microphone power setting (hi or low).  Read 
the manual and follow the instructions.

If you are still having problems, test with another microphone to make sure the 
problem is not with the mic.

If none of those work I would call the factory for further guidance.  They are 
excellent at diagnosis and are very helpful.

Re: [Elecraft] K3S (SDR/superhet hybrid) vs. entry-level direct-sampling radios

[Wayne Burdick]

Igor,

The original DSP code had a math error in the AGC algorithm that caused some 
nonlinearity at certain signal levels. This was corrected. The crystal filters 
have low group delay and low ripple, so the only remaining factor is ADC 
quantization noise. Our ADCs are 16 bits and sampling at 48 kHz (at the 2nd 
IF), with performance as good or better than RF sampling ADCs. Additional ADC 
reference filtering was added to the K3S RF board, and the DSP audio path was 
improved. Now, in practice, there is almost no difference in in-band 
demodulation sound or IMD. 

73,
Wayne
N6KR

[Elecraft] KX3: Bug using macros - parameter AG / AF LIM nor (030)

[Martin Theodor Grewe]

Hi "List",
hi Elecraft,

a small finding using macros and setting Audio (AF):

- you can change volume using AF knob - for sure :-)
- AF LIM ist set to nor 030
- set audio using AF knob to 40
- check audio level with terminal: AG$; AG$040; - check!
- set audio to 040 in terminal: AG040;
- Now you can hear less "noise", audio level is 030 !!
- lets check audio level: AG$;AG$040; - hm strange! sounds like 030!
- no turn the AF knob very slowly... ZAP! Audio switches to REAL 040!

Please fix this :-)

73 de Martin, DL1MTG

[Elecraft] KAT-500 brain trust question

[j...@kk9a.com]

So apparently there is a way to automatically bypass the tuner on some
bands but unfortunately the lighted switch does not indicate this. Many
people have monoband beams (or a SteppIR) with a near perfect match on
10-20m and may only need the tuner for a couple of bands. I would also
like to have N6WM's feature request. I wonder how the KPA-1500's tuner
handles this?

John KK9A



Chris Tate - N6WM ctate at ewnetinc.com
Sun Jul 30 18:39:54 EDT 2017

Don thanks for this, indeed this is the current solution.  Although it is
rather obscure as far as indicators on the front panel.

I would like to convert this to a feature request, as It would be nice if
the firmware supported, and there was another matrix in the KAT500 Utility
that would permit a hard bypass with indicator on a per band basis.  Gives
that warm fuzzy its doing exactly what you want..

E.g. qsy to 20m.. bypass light comes on..

Re: [Elecraft] OT Yamaha CM-500 ear pads

[Charlie T, K3ICH]

Yeah, but really nice velour* replacement pads for the Sony's can be had for
not much more than the $17 they want for those covers.

Charlie k3ICH

*Sweetwater has the best Beyerdynamic velour pads.  These are much more
comfortable than the OEM,  AND they won't flake off like the originals.
I have them on several Sony MDR7506's, which by the way, have much better hi
freq response than the CM-500, but obviously do not have a boom mike.
Try the Sony's. You'll hear stuff you didn't know was there in your music
collection.  Great for all us aging types that are losing our high-end
hearing too.

Not a replacement ear pad, but if you get a new headset, you might want to
cover them with a "Garfield Headphone Softie."  These covers protect the

Search on eBay.

Try a couple different words if it doesn't show the results you want.

I'll bet you'll find some Chicom stuff cheap with free shipping & no tax.
It may take a week or two to get here, but the price is right.

And before you send me an "All 'Made in China' stuff is junk" email, I have had 
the opposite experience.
I've bought lots of little stuff, connectors, misc parts, etc.,  that way and 
have yet to be disappointed in the quality.

Re: [Elecraft] [K2] Random LCD display - Speed and Power

[Don Wilhelm]

Martin,

While that may happen rarely in any K2 - when the firmware is quite 
busy, your video shows it happening frequently, which is abnormal.


The most common cause of that behavior is in late K2s with the new 
encoder - the one with the encoder board that sits close to the control 
board.  If that describes your K2, then flush cut the encoder board 
leads (really close to the board) and do the same on the control board 
in the area where the encoder board can contact the solder side of the 
Control Board.


If your K2 has the older encoder, then look for a bad solder connection 
on either the Control board or the Front Panel board.

I have unfortunately absolutely no ways of measuring anything but if anyone

Re: [Elecraft] [K3S] K3S High SWR Shutdown on FT8?

[Dave B via Elecraft]

Why on earth bother with the tuner in the radio, when you've matched the
antenna to the feeder at the feed point?

All your doing is adding extra loss to both the TX and RX path.

If the match (indicated by VSWR at the rig end of things) is changing
during the 15 second FT8 transmission period, that could be stressing a
PA and or PSU, and you're hearing an over-temp warning from something,
if that's what it is.

Either case, the cause of the wandering VSWR (if that is it) or the lack
of cooing to the PA/PSU needs sorting out.

Lastly, most people running JT (and other digi) modes, don't run the rig
at full power, but between 25 and 50%.  50W is half an S point down on
100W.  Those that do run QRO on those modes, do so with a "Large" PA,
also under run, to keep it very linear (for the modes that need it)
and/or within it's dissipation/duty cycle ratings.

73.

Dave G0WBX.
