[Elecraft] Speaker + Phone

[Wes Stewart]

I normally use a headset while operating.  Now that I'm dabbling with RTTY 
there seems to me little need for this, however, I would still like to hear the 
audio while tuning around.

My headset is plugged into the rear headphone and mic jacks and is a pain to 
unplug so I've set the config to speaker + phone, but it appears that this 
doesn't work (at least on my K3) using the internal speaker. 

Is this normal?  If so, how come?

[Elecraft] K3 -ADC Ref - Change for different Power Supplies?

[Robin Diane Goldstein]

a simple question with probably an obvious answer, but that's why i 
get paid the big bucks!

i've been running my K3 off one power supply and measured the voltage 
at Pin 2 of the ACC at 4.96, so that's what i set up in the CONFIG.

today i got one of the tiny Gamma HPS-1a supplies (its so small its 
hard to imagine its real) and just for giggles measured the voltage 
at Pin 2, and its 4.93.  I can easily enter this into the CONFIG 
menu, but should different PS give different results?  (i did measure 
a difference in the PS output voltages...  Supply "A" was 13.75 and 
the HPS-1a is 13.61.

can't imagine any of this will make a lick of difference, but always 
better to ask.

thanks in advance!

Re: [Elecraft] Firmware Loading!

[Brett Howard]

I've messed with quite a few of these adapters and one of the most rock
solid ones I've used are the chipsets from FTDI.  You can read about their
stuff at http://www.ftdichip.com.  I have no affiliation with the company
other than that I've designed a few of their parts into systems that I've
worked on.  They have drivers for EVERYTHING (I even got them working with
Windows CE) and use them often at home on Linux and except for in the case
of CE I didn't even have to download a driver they just worked.  They also
have some really slick little development modules that you can buy which can
make adding a USB interface really easy...  I've wire wrapped them into
several little project boxes around the shack.

Jim,

Given that you are using a laptop with no serial ports, a USB-to-serial
adapter is probably your simplest option. There are such things as PCMCIA
serial cards, but there is no guarantee that one of them wouldn't give you
just as many problems. You might have better luck with a different
USB-to-serial adapter, but that seems to be pretty much random.

For example, I have two USB-to-serial adapters, both using the same
chipset (although possibly different revision dates, as they were bought
at different times), and both running off the same driver. One of them
causes software crashes with some of the things I try to do with it, but
the other one works fine on the same tasks. Likewise, some people have no
problems with the KUSB adapter from Elecraft, but others report problems
similar to yours.

One thing you might try is taking the powered USB hub out of the picture.
During those relatively infrequent times when you are downloading firmware
to the K3, try plugging your Keyspan adapter directly into the laptop's
USB port without going through the hub, to see if that makes a difference.
It might even make a difference which USB jack you use on the laptop. This
may seem like black magic, but changing USB jacks can sometimes make a
difference with USB ports.

A warning if you try this: If you plug the adapter into a different USB
jack (with or without the hub), there is a good chance that Windows will
assign a different COM port number to it. Fortunately there is a
Properties dialog box you can go into in Device Manager that will let you
change the number back to the one you want to use. USB may be plug 'n
play, but that doesn't always mean it's simple to use!

Re: [Elecraft] [K2] - Very Low Output on 160m

[Don Wilhelm]

Ken,

While 160 meter receive may seem good, the bandpass filter may still 
have a problem.
I would first try to isolate the problem - turn the manual to appendix E 
page 14 - set the transmit power for 5 watts and check the RF voltages 
with your RF Probe at the points listed (Transmit Mixer, Buffer, 
Bandpass Filter, T-R Switch) on both 80 and 160 meters.

If you find the RF voltages equal to or higher than the expected value 
(and they may be much higher when there is little or no power output), 
then the tested stage is working.  At the first point in the list where 
the RF voltage drops substantially below the expected value, that is the 
output of the failing stage.

Try to identify the stage giving trouble and we can likely help further.

73,
Don W3FPR

Re: [Elecraft] Firmware Loading!

[James Harris]

Hi, Dick.
 
Maybe I need to describe my setup a bit more thoroughly.
 
I do not have a Serial Port of any kind on my DELL laptop computer: hence 
trying an Adapter.  
 
So yes, I'm using a KEYSPAN USB-to-Serial Adapter with a "straight through" 
9-pin male to 9-pin female cable to my K3.  
 
But what I didn't tell you is that I have a powered USB Hub installed in a USB 
port on the back of my computer, then the USB Cable that came with the KEYSPAN 
Adapter connected to the KEYSPAN USB-Serial Adapter, then my "straight through" 
Cable connected between the Adapter and the rear of my K3 for loading.
 
I am using Com Port 4.
 
Now that I've given my best description of my setup, it's fairly clear I have 
many connection points where the possible "gremlim" lies unless you can define 
some other area problem!
 
If all of the above isn't REALLY so terribly bad, should I be looking for the 
special Cable you were talking about earlier?  Do you think that would help?
 
I did go to the KEYSPAN link you referenced and downloaded the driver 
again.  It was the same version but maybe it repaied my version.
 
Thanks & Best 73.
 
Jim.

I think you’re using a USB to Serial Adapter in addition to a “straight thru”

Good afternoon, Dick.

 

Thanks for you quick reply.

 

a.) - I have a "straight through" 9 male pin to 9 pin female cable.

b.) - As far as I know, the cable isn't a special USB-to-Serial Cable.  I have 
checked it with a meter and there is straight-through continuity on all pins: 
no groundings or the like.  If I need a special cable, please direct me to a

5 ft. long.

c.) - The KEYSPAN Device Driver is listed as "USA-19H1 - Version String USA-90

Tell me about your cabling between the PC and your K3, and if it's a
USB-to-Serial cable, what Device Driver version are you using?

Use the Windows Device Manager to find the device driver version.  (Start,
right click "my computer", select "manage", and then "Device Manager". Look
for the COM port you're using with your K3.

This isn't operator error.  The K3 Utility shouldn't crash, nor should it

If you have a serial cable and a serial connector on your connector on
the computer, try using the serial cable.  There have been many
problems with the USB to serial converters.

[Elecraft] Firmware Loading!

[James Harris]

Good afternoon, Folks.
 
First off, I have NO COMPLAINTS WHATSOEVER on my K3/100 - Kit [S/N 2802]!  
 
I have five Filters installed [the bandwidths of which I won't mention fearing 
massive retribution - but personally they suite me just fine as I'm a 
CW operator only!], the Ant Tuner and the 1ppm Ref. Oscillator.  A super 
FB/fantastic rig!
 
I do have a question and I feel sure the answer will be "Operator Error"!
 
Here goes:
 
EVERY time I load a new version of Firmware to my rig or save the "current 
configuration" using the current version of the Utility, I have to do them 
both TWICE!
 
On the Firmware updating, all goes well with the FPF Load [every time] but when 
it comes to the DSP Load, it gets to about the 30% mark and locks up [every 
time].  I have to back out of the loading and start again and then it loads OK 
[every time] .
 
This malfunction freezes up the Utility stating afterwards that the Serial Port 
is closed and can't be opened because it is being used by another program.  [ ? 
]  It takes several moments for the Utility to recover.
 
Similar happenings when I "Save the Current Configuration".  It crashes my 
computer.  I have to re-boot and then it saves OK.  That is if the Serial Port 
has recovered.
 
I using the current version of the Utility for Windows XP.  I using a KEYSPAN 
USB to Serial Adapter.
 
Thanks for letting an old man rant & rave!
 
Best 73.
 
Jim.

* FIXED NOISE BLANKER ON/OFF SWITCHING IN BSET MODE: You can
now independently turn the noise blanker (NB) on/off for the sub
receiver in all cases. Previously, the NB switch was locked out
in some cases in BSET mode.

* DVR TRANSMIT WITH MANUAL PTT: Normally, playing a DVR
TX message (M1-M4) automatically asserts PTT and goes into
transmit mode. Now, you can manually assert PTT prior to playing
DVR messages, if necessary. (This might be required to meet external
equipment switching requirements at some stations.) To do this: in the
CONFIG:KDVR3 menu entry, tap ‘1’ until you see “USE PTT”.
(This setting is ignored in VOX mode.)

* ELIMINATED AUDIO NOISE BURST WITH NR + AUTONOTCH:
Very rarely, the combination of NR and autonotch, in the presence of
a strong signal, could result in a loud audio artifact.

* MORE NR (NOISE REDUCTION) SETTINGS:  There are now 32 NR settings.
F1-x to F4-x originally appeared in firmware revision 3.27, and are
recommended for most applications. F5-x to F8-x are the same as
F1-x to F4-x from firmware revision 3.25. They provide a varying mix
between processed (“wet”) and unprocessed (“dry”) audio. When x is 1,
the mix is mostly "dry"; when x is 4, it's 100% "wet". A small letter
“m”
(e.g. "NR m F5-1") reminds you that "mixed" settings are in use.

Note 1: When you’re experimenting with different NR ADJ settings, allow
1 to 3 seconds for the DSP to fully adapt to present signal conditions.

Note 2: F5-x and higher NR settings may alter the amplitude of
single-tone (CW) signals somewhat, depending on the pitch. Voice
signals are less affected.

Is this happening to you only on PSK31, or is it happening also with  
RTTY?

This behavior is (full power at the end) is fully explained by how  
PSK31 works.

In addition to phase modulation, PSK31 also applies a cosinusoidal  
envelope to the signal whenever there is a phase transition between  
two signaling symbols.  Without this envelope shaping, a PSK signal  
would be quite wide.  This is why the transmitter chain must be  
absolutely linear -- it is to maintain this sinusoidal relationship.

This envelope modulation is the reason why a PSK31 signal looks like  
two carriers separated by 31.25 Hz on the waterfall when the op at the  
other end is not typing into the keyboard.  When the idle Varicode is  
sent, the signal looks like a two-tone DSB signal that modulated by a  
15.625 Hz tone.

As a result, the power output when PSK is idling is lower than when  
you type (the variation is even greater with with QPSK31 than BPSK31;  
this is quite obvious when you compare their modulation constellations).

The original specs for PSK31 calls for a (approximately 3/4 second)  
squelch tail at the end of transmission.  Most PSK31 modems obey this  
during transmission (whether they actually use it as a squelch or not  
during receive).  Unless the software actually drops the peak power by  
3 dB during this end-of-transmission squelch, you will see the output  
power rise during this period.

Since RTTY is a 100% duty cycle mode, it will not have this behavior  
even if you transmit a prolonged mark tone at the start or at the end  
of a transmission (many software transmits a slightly prolonged mark  
just before the RTTY diddle begins). The only time you should see RTTY  
change power when transmitting is if the RTTY tone pair is right at  
the edge of a filter passband so that one tone is more attenuate then  
the other one.)

If you are also seeing the more-power-at-the-end behavior in RTTY, you  
might want to check to make sure that your transmit tone pair (from  
software) is centered in your transmitter's passband.

[Elecraft] K3 Operator Error

[Kjeld Holm]

Thanks to Gordan and Larry. 
 
I do not run the station hot. Max temp seen has been 73 degrees centigrade
(auto shut down is at 85 C). Most of the time max temp is 67 C. 
 
I do have the same number of ALC bars on 80 meters as on 15 meters.
Increasing the output from my sound card just made the output totally stable
at 40 W instead of varying between 30 and 40 W. So all I got was
overloading. Mic gain is up at 50.
 
By the way RTTY is down about half of the power of that on PSK 31.
 
To the best of my knowledge PSK31 and RTTY has been up at 85 W on 80 meters
until two weeks ago.
 
Just now I noticed that for the last second or so of the transmission it
seems like I have full output also on 80 meters. BUT it is not a question of
warming up as the full output is seen only for the last second whether I am
transmitting for two seconds or for about twenty seconds.

Dear all,

Problem:
Low output on RTTY and PSK31 on 80 meters using the mode DATA-R and output
from sound card.

Situation:
Starting on 15 meters running RTTY or PSK31 with an output of about 85 W.
Using Ham Radio Deluxe switching to 80 meters, also switching antenna.
The output falls down to about 40 W.

Changing to CW (still 80 meters, same antenna) I get 85 W again like on 15
meters.

Which settting have I overlooked that brings my output down?

[Elecraft] Loaded K2 4 sale, reduced price or B.O.

[Penninger Radio]

Hello all,  
I am wanting to buy a K3 and need to sell my loaded K2.  
The serial # is 3644.  I have used the rig for receive only as I never finished 
the transmitter alignment.  
My ears could not discern a difference in tone.  The soldering is professional. 
 
The options have never been installed, they are:

KSB2 - assembled  
K160RX - assembled 
KNB2 - assembled 
KIO2 - assembled 
KAF2 - assembled 
KAT2 - still in kit form  

I have a non smoking environment and the rig is in excellent condition.  
I am asking $950.00, shipping is FREE to continental US.  I can take credit 
cards (MasterCard, visa or discover) through my company, Penninger Radio ( 
www.PenningerRadio.com ) 
please reply off list to char...@penningerradio.com 
73 and thanks for the bandwidth.

This will most likely result in the radio's long term ALC gradually 
increasing gain in the transmit path until it either (a) runs out of 
gain or (b) hits it internal limits.

Not recommended.

 I'm active in WSPR mode, which is a single tone as well.
 Mode = "DATA A", ALC = 4 bars, PWR = 5W.
 An external wattmeter shows an absolutely steady power throughout 
 the entire
 2-minute TX cycle.
 The bottom cover just underneath the LPA gets pretty hot, but at 5W 
 the KPA3
 is bypassed.
 Will run a test at higher power to see whether or not it makes a 
 difference.

Julian, you can force the KPA3 to stay on by means of a workaround:
Set PWR = 15W, then define actual TX power using MIC gain.

At the same time, a verification of the audio level

Re: [Elecraft] [K3] K3 Power Output

[hb9ari]

Hi Julian,

I don't remember the reason(...) but i work
in USB mode. I will try to work in DATA A
mode this week-end and at the same time,
recover the reason for the USB mode choice!
(i read that somewhere!)

For the ALC, i set the level just before the
end of "variation" (if i'm correct, as i'm not
in my shack, it should be 4 steady bars and
the 5th flashing?)
ele
Thank you for the info.

Re: [Elecraft] [K3] K3 Power Output

[Alexandr Kobranov]

Hi Markus,
you prabably know but maybe good for the others trying WSJT/WSPR:
You can try very simply power levels per tone by using WSJT menu Setup 
- Generate messages for test tones.
Then you have @A - @D and @1000 and @2000 in TX1 - TX6 windows
You can test each tone separately and try to adjust level of TX EQ to 
obtain the best distribution.
Yes, there are differencies, very big sometimes.
Maybe later when TX EQ will be -per mode- saved and (if any chance) 
user selected  frq of setting point possible there will be better game 
with it.

Good luck,
73!

It would be nice to have the option to leave the KPA3 in at low power. I
avoid using QRP for high duty cycle modes because I'm afraid it stresses the
radio more than using 12W does.

Are you not using DATA A for this, Rudolph? If so, you can set the audio
drive for a steady 4 bars in the "ALC" scale and the K3 will adjust the
power for the value selected across the whole range of the audio spectrum
(that you might reasonably want to use.)

It didn't always work like this, but it has for many months now. Using PSK31
I can click on a signal anywhere from about 300Hz to 2700Hz, call them and
get exactly the power requested (within reason, of course.)

I'm active in WSPR mode, which is a single tone as well.
Mode = "DATA A", ALC = 4 bars, PWR = 5W.
An external wattmeter shows an absolutely steady power throughout the entire
2-minute TX cycle.
The bottom cover just underneath the LPA gets pretty hot, but at 5W the KPA3
is bypassed.
Will run a test at higher power to see whether or not it makes a difference.

73, Markus HB9BRJ

[Elecraft] K3 - on the bands

[Bob Towers]

Hm. a perspective from the other side of the Pond.

On the contrary, I found conditions pretty reasonable on 20m at the 
weekend. I had a go at the SCC RTTY contest and got most of your East 
Coast regulars, plus some far-east Siberian stuff and north of South 
America.

If that's bad conditions, what will good conditions be like?

[Elecraft] Region 1 SSB Field Day

[dj7mgq]

Hi,

this weekend from Saturday 13.00 UTC to Sunday 12.59 UTC is the Region  
1 SSB Field Day. So keep your ears open for puny signals coming from  
our side of the pond! This year our local club will be running Field  
Day stations at three different QTHs simultaneously.


For more information see the following links:

German rules (in English):


German FD Stations & QTHs:


South African rules:


British Rules:



Please work as many portable stations in region 1 as possible. Thank you!

vy 73 de toby
