Re: [Elecraft] KX3 RF out voltage measurements...

[Phil Wheeler]

David,

You'll likely get more help if you describe what 
is causing you to think you might have an RF out 
issue with your KX3.

Re: [Elecraft] KX3 RF out voltage measurements...

[thelastdb]

David,
Set the radio for 5W in the TUNE menu first. Then press the tune button. I make 
all of my power measurements with my KX3 set to 5W and TUNE.
John and I use these DL1s extensively. Google KN5L DL1 and read up on the diode 
characterization and further reading about its use.

[Elecraft] K3 8khz wide sig tracks VFO A ~30khz lower in frequency

[Sam Morgan]

I have a 8-9 khz wide signal that follows my VFO A around. I saw this on 
160m and also in 10m this morning. I haven't checked the other bands.


Images can be seen here:
https://picasaweb.google.com/k5oai.sam/6293813435183959297

No antenna was connected to the K3. The only cables connected to the P3 
were: Coax and RS232 from K3. I attached the RS232 to the computer to 
get the snap shots, bet the signal did not change with it connected to 
the computer or not.


Note: During the snapshots I bumped the VFO knob from 28.120 to 
28.119.40 by mistake during the snapshots, but that doesn't have any 
effect on the fact there is this big wide scary 8-9khz wide signal ~ 30 
khz down from VFO A that is tracking my main VFO.


What is going on, has my K-Line been invaded by something? If so what 
and how do I fix it?

[Elecraft] K2 DSP unit

[Ted]

I just bought a K2/100 (I now own 4 and a K3, KPA 500 and scope) and it 
came with DSP.  I checked it out and it works FB but don't use DSP so 
the module is an extra now.  Anyone wishing to own a DSP module for 
their K2 can buy mine for $165 which includes shipping within the USA.  
Please contact me at the above email address or via QRZ.com.

Re: [Elecraft] KX3 RF out voltage measurements...

[David Davis]

Phil. 

My testing started when I started to realize that I might not have any RF 
output. 

I started to believe this to be the situation when no matter what band or mode 
I tried I was no longer able to make a contact of any type while working 
portable. 

When I returned home and connected my KX3 back up to my KXPA100 I noticed that 
no matter what I set the KX3 output too the KXPA100 would effectively not put 
out anything. The 25w led would barely flicker when I would key up the radio. 
This caused me to believe the KX3 either had little to no RF output at all or 
barely enough to be able to drive the KXPA100.

[Elecraft] [ELECRAFT][K3][P3] Macro Question on Noise Reduction

[David Box]

I am trying to set up macros to use for different bands and modes 
changes.  One thing that I cannot find how to do is to check on the 
status of a switched function and then set if needed.  An example is 
that for changing to 20M SSB I would like to turn on Noise Reduction but 
the only way I can find to do that is using the SWT34  which toggles the 
function so that depending on the prior mode I have no knowledge if it 
is turned off or on.


Noise Blanker has its own command but cannot find the equivalent for the 
Noise Reduction.


Macro capability is pretty neat and just learning so any comments 
appreciated.

Re: [Elecraft] KX3 RF out voltage measurements...

[Phil Wheeler]

David,

If you have a dummy load and any sort of Wattmeter 
which can measure in 10-20 W range, that should 
tell you if you're getting NO power out.


And make sure you have the power out dialed in at 
10 watts or so in the KX3, not set to zero.

[Elecraft] Solar Charge Controllers (was Field Day)

[Jim Brown]

Yes on all counts. This unit would be described as a simple hysteresis 
controller -- it doesn't pulse the charge current, it simply turns 
charging on if the battery voltage is less than full charge, turns 
charging off when that voltage is reached, and turns charging back on 
when battery voltage has dropped some pre-set amount. Chargers like this 
are, by their nature, free of RFI, because there's no square wave to 
generate RF trash. Several years ago, a local ham pointed me to this 
product, which does the same thing, but is rated for a lot less current.


https://www.amazon.com/Sunforce-7-Amp-Charge-Controller/dp/B0006JO0XI/ref=sr_1_1?srs=2601531011&ie=UTF8&qid=1465406526&sr=8-1&keywords=solar+charge+controller

The more efficient charge controllers of which Bill speaks are MPPT 
controllers; they have a DC-DC converter that converts the relatively 
high panel voltage at low current to lower voltage at the higher current 
that the battery can accept. This allows a large battery to accept more 
charge in a shorter period of time. By their nature, they use square 
waves, so they can be noisy, and most MPPT charge controllers ARE noisy. 
The Genesun MPPT controllers create very little RF noise, and won't be 
heard in most installations. My solar panels are next to my 160M 
antenna, so I need a choke on panel side of the controller to prevent 
noise pickup on that antenna. That's a pretty extreme condition. :) So 
I'd call the Genasun controllers RF quiet.

current modifications change some of the circuit resistors to keep the 
RFI low, so low RFI was one of the design goals.


This controller feeds full panel current to the battery until the 
voltage reaches the float voltage and then floats the battery at that 
voltage. This techniqueis a good for lead-acid batteries but is 
probably not appropriate for lithium family chemistries.


It is also not the most efficient way to charge a lead-acid battery. 
Higher efficiency can be achieved by charging at a slightly higher 
voltage and only reducing the voltage to the float voltage when the 
charge current becomes low. With my 7.5A rated panels, I can recover 
the batteries charge in a day after spending a weekend contesting at 
100W, so the additional efficiency is not a major concern. The charge 
system also works well on field day at QRP power levels.

From the KX2 manual (which is online)

Sensitivity (MDS), 500-Hz bandwidth
-136 dBm (typ.), preamp on. Note: Sensitivity rolls off significantly 
below 3.0 MHz
due to protective high-pass filtering. Preamp-on MDS is typically -105 
dBm at 1.5
MHz, and -80 dBm at 1.0 MHz, sufficient for emergency AM broadcast 
signal copy.


I interpret this to say that it's good enough to hear strong local 
signals, but it's not an AM DXer's receiver. The high pass filter has a 
turnover of 3 MHz, is 30 dB down at 1.5 MHz, and 56 dB down at 1 MHz.


If you're looking for a nice AM BC RX, consider the Tecsun PL-660 and 
PL-880.

[Elecraft] K3 Firmware Feature Requests

[Matt Murphy]

I'm not sure if this is on the list of requested firmware features, so I'll
mention it here just in case:

Request 1: I'd like to be able to adjust the RX filter shift/width while
transmitting.  I often take a moment to assess things like passband, RIT,
etc. when CQing during a contest, and if I'm extensively using the
narrowest filter/shift to dig out weak signals, I like to revert to a wider
passband for the next QSO.  While I know I could do this using a CAT
command, I'd like to be able to do it using the knob.

Request 2:  After using a Flex Maestro there is one clever feature that I
think the K3 could incorporate via a small firmware change.  The Maestro
has a front panel knob that adjusts the AGC threshold.  I find this useful
because in some band conditions turning the knob feels like it makes a big
improvement (different signal levels, static, etc.).  I'd like to request
that one of the K3's front-panel encoders be optionally made to adjust AGC
threshold. Perhaps VFOB or the RIT knob -- perhaps both RIT and XIT lights
could come on when that knob was in AGC THRESH mode.   (maybe a knob on the
K-Pod could be assigned to this as well... I don't own one yet).

Both would be neat ... however, the last time I checked, no one had yet 
invented "A Small Firmware" Change. :-)

I would like to second that request as well, with a bit of a
modification...  I find that I often will fire a macro off to the K3,
and because it is in transmit mode, nothing happens...  I used to do
this with my Icom 756 PROIII.

[Elecraft] [KX2] DC Power

[Jim H via Elecraft]

Two questions regarding the KX2.
1. Can the KXBC2 be used as a power supply, with appropriate adapter, to  
power the KX2?
2. Can someone explain why Elecraft used a Li-ion battery rather than  
other Lithium chemistries in the KX2?
Some chemistries are safer than others.

Re: [Elecraft] K3 Firmware Feature Requests

[Jim McDonald]

I see in the K3 & KX3 Programmer's Reference (page 16) that the AGC
threshold, MN044 or MP044, is accessible via software.  I have what DXLab
calls user-defined sliders for AF and RF gain and power; maybe a similar
slider could be created for AGC threshold.  Or maybe a stepped macro for the
radio or the K-Pod could be developed.

Re: [Elecraft] K3 Firmware Feature Requests

[Drew AF2Z]

Regarding a front panel knob for AGC threshold adjustment, I have 
assigned AGC Threshold and Slope as keyswitch macros to M1 tap & M1 hold 
respectively. Then it's just a matter of selecting either and turning 
VFO A to adjust.

Re: [Elecraft] KX3 RF out voltage measurements...

[David Davis]

Myron,

Thank you very much for the information. It helped me check the RF
output on my KX3. I was able to determine that the power output is
exactly where it should be. That is why I really enjoy this mailing
list. There are good people here that always offer great help.

In the end the issue appears to be caused by the ribbon cable that
connects the two halves of the radio. I had opened the radio a few days
before the last time I had used it. I must have knocked the cable loose.
While I was checking the radio I checked the connections of the cable
and it was loose. After I got the radio back together I used your
suggestions and the measurements were perfect.

I also Googled your website. It was like finding a gold mine. There is
all kinds of good information on your site.

Thank you,

David

Re: [Elecraft] MAC logging software

[Scott Manthe]

You'll get recommendations for MacLoggerDX, and it is nice software, but 
it's also $95. I recommend RUMLog, which does just about everything MLDX 
does, but its free (or whatever you choose to donate). There is a 
contest version, called RUMped as well as versions for the iPad/iPhone 
and they all can be downloaded here:

http://www.dl2rum.de/rumsoft/RUMsoft_Home.html

Rather than charge you $95 up front, DL2RUM allows you to decide for 
yourself how much the programs are worth to you and there's a Paypal 
donation button on the page, if you decide you like the programs. I do 
like them, so I donate once a year. You might decide you like 
MacLoggerDX and that it's worth the $95, but I'd suggest trying the 
RUMlog offerings first.

Myron,
Thank you very much for the information. It helped me check the RF output on my 
KX3. I was able to determine that the power output is exactly where it should 
be. That is why I really enjoy this mailing list. There are good people here 
that always offer great help.
In the end the issue appears to be caused by the ribbon cable that connects the 
two halves of the radio. I had opened the radio a few days before the last time 
I had used it. I must have knocked the cable loose. While I was checking the 
radio I checked the connections of the cable and it was loose. After I got the 
radio back together I used your suggestions and the measurements were perfect. 
I also Googled your website. It was like finding a gold mine. There is all 
kinds of good information on your site. 
Thank you,
David

David,

Set the radio for 5W in the TUNE menu first. Then press the tune button. I make 
all of my power measurements with my KX3 set to 5W and TUNE.

John and I use these DL1s extensively. Google KN5L DL1 and read up on the diode 
characterization and further reading about its use.

Subject: [Elecraft] KX3 RF out voltage measurements... 

I might have an RF out issue with my KX3 but I am not sure how to test it.

I have an Elecraft DL1 and a DMM that I figure I can use to check the RF
voltages and verify the power out. However, I am not sure of the exact
process on how to do this. If I am keying the mic on SSB do I need to
speak into the mic to be able to measure the voltages or just key the
mic with silence? I would assume I need to be speaking into the mic.

The reason I ask this is because if I just key the mic with silence and
the radio set for 10W with a input power supply of 13.5V DC I measure
4.7mv DC at the TP1 on the DL1 unit.

If I speak into the mic I see voltages from 11 - 18V DC from the TP1 on
the DL1 unit. It seems to me that I need to be speaking into the mic. I
figure if I was checking the RF out in CW mode I would need to key the
keyer in some fashion.

I know this seems like an elementary level question but I would really
like to verify the RF power out.

Any information is greatly appreciated in advance.

Thanks!
David

Re: [Elecraft] Solar Charge Controllers (was Field Day)

[Jack Brindle]

Thee is an issue with the cheaper solar controllers - they tend to place the 
switching transistor in the ground leg, making connections difficult. For 
example the Sunforce controller that Jim mentions uses an N-channel FET as its 
pass transistor, in the ground lead. If you then connect the radio or other 
load to the battery while it is being charged, you can end up with a floating 
ground. One local solar expert discovered that his setup of this kind caused 
massive current flow on the shield connection of a USB cable - it was 
essentially carrying all the ground current!

The better controllers use P-channel FETs in the positive leg of the charger, 
as shown in Mike Bryce (WB8VGE)’s design in the ARRL publication “Emergency 
Power For Radio Communications” and also in the CirKits design that Bill 
mentions. I have a pair of each of these and will be using them this Field Day 
to keep a pair of Marine deep-cycle batteries charged from a 100 watt solar 
array and also a 45 watt backup array. I like the WB8VGE design better, but it 
won’t handle the 100 watt array without modification, which caused me to pick 
up the CCS3 boards. Unfortunately the WB8VGE kits appear to no longer be 
available, but the CirKits boards (also designed and sold by a ham, forgot his 
call) are very much available and a fun build.

- Jack, W6FB

P.S. Listen for both Bill, myself and many others from the WVARA operation at 
Mora Hill, CA using the call K6EI in FD. It is an all-K3/QRP operation with 
outstanding antennas in a location you have to see to believe. And, if you are 
in the area and searching for a place to play, look us up!
