Re: [Elecraft] k-pod data cable

[Bill Frantz]

I read "short distance..." after sending my stuff. I think you 
are correct about the I2C electrical connection, but I still 
think Elecraft needs a box to box communication protocol which 
allows multi-masters. USB would do, but probably isn't the only 
choice. Ethernet?


There is a question of just how much distance needs to be 
supported. If you have your KPA500 at the base of your antenna, 
that is quite a distance, on the other hand, you probably don't 
need to control you K3 from there.

Re: [Elecraft] WSJT-X MSK144 & Transmit Delay

[M. George]

PC Clock drift can be quite bad as we all know.  The default NTP server
sync interval for Windows 10, is once a week.  So your clock can be way off
by the time you sync again.  With a one time NTP sync, you can still be off
into the 100 ms range.  I suspect some of the JST related software etc...
might force a sync at startup and or do NTP server syncs on their own?
Someone else will need to chime in on that.

The best time sync you are going to get for Windows and Linux / BSD based
operating systems will be us use the full on NTP client.  For windows,
Meinberg has a nice graphical client that installs and sets itself up as a
service and disables the windows NTP client service.  During the Meinberg
NTP install, you have an option to draw from the NTP pool of NTP servers
and you can also type in your own preferred NTP server list.  The full NTP
client does more than just sync your clock... over time it will calculate
the drift of your clock and discipline your clock automatically between
sync checks to your selected NTP servers.  The drift is calculated in PPM
and for the curious you can see how bad your clock is.

Here is the link for the Win32 install of the Meinberg client (free):


https://www.meinbergglobal.com/english/sw/ntp.htm#ntp_stable

I run 3 GPS disciplined NTP servers (3 separate GPS receivers) here at my
QTH and if you want, you are welcome to use time.nc7j.com as one of your
NTP servers.  On this end, time.nc7j.com is accurate into the nano second
range as compared to the GPS on board atomic clocks.  Via NTP UDP sync over
the Internet, the best you will typically do is get down into the lower
microsecond range...  and far more accurate than any thing most would ever
need.  time.nc7j.com is also a member of the NTP pool and you can see if
it's up and running be going to this link:
http://www.pool.ntp.org/scores/time.nc7j.com  The chart here doesn't show
the accuracy of the time.nc7j.com, but it shows the ping offset from LA to
Utah and it's normal to vary +- 10ms.  Your mileage will vary with your
round trip ping times to any NTP server, but over time, NTP will do an
amazing job of figuring out your PC clock drift and then disciplining it on
the fly.

For the totally 'time accuracy obsessed', you can install the Meinberg NTP
monitor too and monitor your clock accuracy via logged NTP statistics:
https://www.meinbergglobal.com/english/sw/ntp-server-monitor.htm#download

The Meinberg apps are GUI's that make native calls to the full NTP install
under the covers and they are totally free and free of any nag related
nonsense.

If you are running Linux or iOS, you are already running a native NTP
client I suspect and you can read up on how to configure it just like the
Meinberg Windows GUI's do for Windows.

It is likely that the interface used by the K-Pod is the I2C bus

Re: [Elecraft] K-Pod question

You could assign it to a PF key and then make a macro that holds
thatkey and then have the KPod execute the macro.


That's what I said ... assign Function VFO B -> A to one of the PF
keys (e.g. PF1) and use it instead of A/B.  It's actually closer
to the VFO B knob than A/B and easier to reach.

Re: [Elecraft] k-pod data cable

[Wes Stewart]

Hi Fred (I have one of your books BTW)

Save your money.  When I said. "As I've written before", what I had said earlier 
was:


"I saw a similar problem.  Only tapping a button appeared to send the command to 
the K3 but the K3 failed to respond.  For example, I had my K-Pod set up to use 
a tap of F5 to invoke M1, where my call was stored.  Tapping F5 would result in 
"MSG 1" showing up in the VFO B space on the display but M1 was not activated.  
(Tony G6GLP) has also reported this problem.  Tapping M1 on the K3 works every 
time."


Read the last sentence.  Additionally, there are other messages in Bank 2 so 
something should have been sent.


But this thread and others---IMHO of course---exposes a missed opportunity.  
Instead of this Mickey Mouse way of writing a limited number of macros, that 
have to be sent to the K3 and stored, only to be executed by a K-Pod over a 
dubious interface, the macros should simply be saved in the K-Pod in the first 
place and sent via USB and/or RS232.

On 1/16/2017 3:43 PM, Cady, Fred wrote:

  2) I have Macro 13 (tap F5) set to activate MSG 1 (SWT 21)  As I've written
before, many times, tapping this button resulted in "MSG1" displayed on the
radio but no message was transmitted.

Remember there are two banks of memories.  I'll bet the Macro label is MSG1 
(which is displayed when the macro is executing) but you are in one of the 
banks that doesn't have the message programmed into it.  To switch banks, hold 
the REC key.  Unfortunately that is a toggle so you can't hold it in a macro 
and have to be in Bank 1 or Bank 2 deterministically.

That works, but of course after each 'jump', VFO-B is at the frequency of the

not quite as nice as using the markers on the P3.

Subject: [Elecraft] K-Pod question

When the K-Pod was first introduced, there was some indication that a
future enhancement would allow it to control the P3 - specifically, to
adjust the markers and 'tap to QSY'.

Is this feature available yet, or imminent?

I discovered that the P3 is pretty useful for unassisted search and pounce
in last weekend's RTTY contest - While working one station on VFO-A, I'd
move marker A up to the 'mark' tone of the next RTTY signal up the band. As
soon as the QSO was logged, a tap on the P3 knob would jump to the next
station to work.  Then move Marker A again and repeat. With a little
practice, and the SPAN set fairly narrow, I could nail the tuning every
time, provided I didn't bump the P3 knob when tapping it.

Although that worked well, it was a lot of reaching to the P3. It would be
a BIG improvement if a K-Pod, right next to the keyboard, could control
those functions.

Can it?

Re: [Elecraft] k-pod data cable

[Ron D'Eau Claire]

Sometimes it is not easy to orient the connector correctly to be sure you are 
clipping the right wire so we included a photo of the 6P6C connector in 
Appendix B of the KPOD owner's manual clearly identifying pin 1 (page 19 of the 
Rev H KPOD Owner's manual).

Yesterday I built a 5 foot long cable using 6P6C connectors and some telephone

(I identified which pin was #1 by measuring the Elecraft supplied cable.)  It 
seems to work fine, but I haven't used it enough for those little hidden

If I need to move to twisted pair to get better isolation (thanks Jim), I will 
need to identify which wires to twist together. From Harry's pin out below, it 
looks like twisting pins 3&4 (Ground and Data) as well as pins 5&6 (Clock and

[Elecraft] K3s remote line input gain setting

[Gary Schwartz]

Can anyone tell me the command to remotely set the Line Input gain.  I 
know that the rig first has to be placed in the Line Input mode, which I 
can do remotely.  But, the Line In Gain is distinctly separate from the 
Mic Gain.  There is a remote command that sets the Mic Gain correctly, 
but there is no command I can find to set the Line In gain when in Line 
mode from a remote site.


To be perfectly clear, the rig works correctly using the real front 
panel controls.  If you select Line In, then the Mic Gain becomes the 
Line In Gain.  When you change to a Mic input, changing the front panel 
Mic Gain has no effect on the line input level, i.e., the radio 
remembers the separate Line In gain setting.  This is certainly easy to 
verify.  Further, using the Elecraft Utility in Debug Mode, different 
codes are sent by the front panel Mic /Speed knob depending on whether 
you are in Mic or Line input mode.


If there is a command, it is apparently undocumented unless one of you 
out there happens to know it.


Thanks.
Gary

Actually, the reason IMD performance is worse at 10W than at 20W is that 
at 10W you're still in the 10W section of the radio, while at 20W you're 
using the 100W amp. Once you're into the 100W amp, IMD performance 
degrades with increasing power. The K3 is capable of 120W, but since IMD 
increases rapidly above 100W, output is limited to 110W in firmware.


As I see it, IMD is most important when a radio is driving a power amp, 
and most modern amps will get to rated power with about 50W. The KPA500 
needs 25-30W drive. As indicated by measured CW keying bandwidth, the K3 
is a VERY clean radio below 60W.


IMD performance also degrades with reduced DC supply voltage. As I 
understand it, 13.8V is the nominal design voltage, and 15V is max rated.


As to the original query about temperature -- Wes is exactly right about 
low power and efficiency.  I do little or no ragchewing and mostly 
operate CW and SSB, but I do run RTTY for contesting and some digital 
modes that run keydown for about 50 sec and repeat every minute. When I 
do that on 6M, where the amp has the lowest efficiency, the fan will get 
pretty loud before the end of each TX cycle. That can be reduced a bit 
by setting the idle fan speed higher. It's a menu setting.

Re: [Elecraft] k-pod data cable

[Jim Brown]

Another point. Ribbon cable is TERRIBLE for RFI susceptibility. Twisted 
pair is FAR superior IF each signals is on a pair. CAT5/6 is four 
tightly twisted pairs, 100 ohm impedance, each a different twist ratio 
to minimize crosstalk. I don't know anything about how the K-Pod uses 
that cable. For RFI, twisting is more important than shielding.

Re: [Elecraft] Battery Leakage

I like using Lithium-Ion batteries in a variety of sizes.  But having

them away from flammables when unattended.

However, I noticed you said 'Lithium' not Lithium-ion.  Consumers have

Re: [Elecraft] K-Pod question

[Dave Fugleberg]

I experimented a bit with the method suggested by Fred, using VFO-B to
'mark' the next signal up the band, and then using A/B to 'jump' to it.
That works, but of course after each 'jump', VFO-B is at the frequency of
the previous QSO. That means a little extra excursion to tune VFO-B past
the current VFO-A frequency to get to the next one up the band. No big
deal, just not quite as nice as using the markers on the P3.
Anyhow, thanks for the tip. In hindsight it's pretty obvious, but I
wouldn't have thought of it without your suggestion.

Re: [Elecraft] k-pod data cable

[Jean-François Ménard]

Hi,

Unfortunately, something I did not mentioned in my previous post, it was 
implicite for me, but by using CAT6 cable, I was thinking about making our own 
cable and connectors to avoid using flat ribbon cable. 

The twisted part of the cable will improve communication reliability for sure. 
Noel mentioned to me that he needs a cable run approximately 25 feet long. My 
guess, this should work. But many other factors must be involved, like "how the 
station has been properly setup? », and so on. 

Experimentation here is the key…. an important part in our hobby. :-)

Re: [Elecraft] k-pod data cable

[Ron D'Eau Claire]

Jeff makes an excellent point about long data cables. If you decide to try a
longer ribbon cable first and are not interested in making your own, buy an
RJ45 cable and F-F coupler to extend the Elecraft cable. Be sure to put the
Elecraft cable closest to the K3, since it does not have pin 1 connected,
and use the RJ45 cable for the rest of the run.

Let me repeat my earlier comment: Macros 1 through 8 are accessed by HOLDING
the KPOD switches for more than 1/2 second. Tapping (holding for less than
1/2 second) accesses K3 Macros 9 though 16. That might be what some of the
people experiencing "unreliable" switch behavior are doing and not getting
the reaction they expect from macros 1 through 8.

Re: [Elecraft] KPA500 Temps?

[Wes Stewart]

When you put the KPA500 into transmit there is some fixed (FET) drain current 
regardless of whether you are driving the PA or not. Likewise, the power supply 
is supplying this current.  So the efficiency is zero and all of this DC power 
is converted to heat, not RF.  Efficiency increases with drive.


So what you are doing is poor practice.  Furthermore, IMD performance of the 
driver (K3) is likely better at higher power. It's for sure better at 20W than 10W.

[Elecraft] k-pod data cable

[Jean-François Ménard]

Hi Noel

Usually, such typical serial communication, like RS-232, could handle 15m with 
proper cable gauge and shielding. This cable has short transmission distance 
because of noise limiting the transmission of high numbers of bits per second. 

But in our case here, strong RF field is involved when transmitting, so the 
distance could be much shorter than 15m to avoid data corruption. I would 
strongly suggest to try using a cable made with shielded CAT6 cable, not 
standard ribbon cable usually used for phone,etc. Adding a few clip-on ferrite 
at both ends with as much turns you can could be a great addition too avoid 
misleading with unwanted noise in the communication line and ground path.

Hope this help.

Re: [Elecraft] Elecraft Digest, Vol 153, Issue 21

[Dauer, Edward]

Same thing here this past weekend.  Never noticed it before, but during the 
NAQP there were four or five occasions on which the K-Pod needed a second tap.  
I am using the Elecraft-issue cable and the K3 modification for DC.  It wasn’t 
a big deal, but any delay in a contest exchange is noticeable.   As to the 
thought that the problem might be RF in the shack, that seems unlikely since 
the mis-press or whatever it is occurs before the XMTR is keyed when the tap is 
meant to activate a memory message.  Could it be that the buttons have some 
free play in their holdings such that pressing one asymmetrically can result in 
a lesser contact, or is that mechanically not possible? 

Even so, having a K-Pod is a significant edge in operating comfort.  But if 
there’s a fix for this issue, it would be good to know

VE3WDM and Mike ON or K3 functions such as spot or A/B ) the macro did not 
send. Sometimes it took pressing the "F" button 3 times. Other times it was 
first press and I noticed this on all the F buttons I was using which was F1,2 
4 and 8. Has anyone else had this? My question to Elecraft (as I know they 
monitor the list) isis  there an issue with my new K-pod? It is very 
frustrating during a contest to send your call and have it not happen or your 
exchange and nothing and as said sometimes up to 3 tries.  As well to want to 
spot a station and nothing happens or A/B and nothing happens.

Thanks

Mike Weir

[NOEL POULIN]

Hello,
Anybody in this group, using a different length data cable supplied with 
the k-pod??The cable uses two 6P6C modular male connectors, and requires 
5 conductors..

Elecraft supplies a 36" long cable??

correctly???

[Elecraft] KPA500 Temps?

[cx7tt]

For the NAQP cw party this past weekend, I ran low power. Rather than
'stress' the K3s with 100W, I chose to run 6W thru KPA500, giving me 100w.

During a one hour run period, 125+ Qs on 15m, I noticed the KPA500 temp
at 51C which surprised me. Idle temp in the shack is generally around 33
to 35C. I expected much lower temp at 100w output.

Why the higher temp and is it not related to power out?

[Elecraft] QRP/outdoors/SOTA/KX2 presentation at the Palm Springs hamfest - content streaming question

[Arthur Gunn]

In an earlier posting I wondered if this hamfest will be streaming the speakers 
sessions. The special interest had been Wayne’s KX2 talk about its features for 
SOTA type of field trips. The hamfest organizer has advised me that this 
hamfest will not be streamed as I had inquired.

Re: [Elecraft] Elecraft CW Net options

[Kenneth Christiansen]

Hi Brian

Sorry for the alligator operation. I usually do not call with the 500 watts but 
turn it on during a QSO if needed. My noise was low last night for being in my 
location but it is never low compared to camping. I thought I might have heard 
something but could not see it on the P3 or even be sure it was not just noise 
ringing in my ears.1

Let's hope Kevin is back on next week and the bands get better again.

Re: [Elecraft] Battery Leakage

[Marc Veeneman via Elecraft]

Threw away a stored RCR123 last week due to leakage.  The light brown oily 
fluid could be washed off the container but the positive pole of the cell was 
partially gone.  The other 3 cells were still charged and now in use.

That's the first rechargeable lithium I've seen with leakage.

It's not a reliable ntp "client" you need, but a reliably clean and
reachable ntp *server*.

Use the ntp pool project, not the default Windows offering for a server,
as that is so congested as to be virtually unusable.   The pool project
will find the best (closest in network terms) one for you to use.

Even using Windows own timekeeping tools and systems, when they are
pointed at pool.ntp.org for example, they will do the job more than
adequately for any of the JT modes.

No third party software needed.

https://www.tenforums.com/tutorials/6410-clock-synchronize-internet-time-server-windows-10-a.html

Will show you how.

That was found top of the list for a Google search of  "windows10
internet time settings"  There are many other hits.

73.

Dave G0WBX.
