... or try to diagnose and fix it yourself. The VFO A and B encoders
are the same, so you could swap them to determine if it's the encoder
that's bad or something else

Re: [Elecraft] K3 problem

[Clark Macaulay]

Jim,

In my view, that is a very wise decision.  I'm 77 yrs of age ("seasoned
citizen") with shaky hands.  After observing just how small the SMD
components are when trying to install the K-pod mod for powering via its
data cable,  I realized my 6 year old K3 with an annoying problem (PWR
control mushy) needed to be sent home (aka The SPA).

What I hadn't expected was that they would also bring the radio up to the
latest specs by installing gold pins, installing the latest firmware (which
I thought I had done), repairing a LPA problem I didn't know I had, and
performing all of the calibrations (my POWER reading was significantly off,
they said).  Yes, it was a little expensive ($400), but well worth it, and
my K3 will now serve me well for many years to come.  You will not be
disappointed.

Re: [Elecraft] K3 problem

[George Thornton]

I want to echo my appreciation of Elecraft repair service.

I had my K3 in a few years ago after it malfunctioned during field use.

They also went through it and made all sorts of additions and calibrations.

Really well worth the moderate cost and inconvenience.

The unit continues to perform flawlessly.

Re: [Elecraft] K3 problem

[Grant Youngman]

And if you don’t have a good condition original shipping container for the K3/S 
(or P3), it’s worth the small cost and wait to order a new one with the 
internal foam supports from Elecraft.  The shipping containers are available on 
the spare parts menu.

Re: [Elecraft] K3 Problem

[Don Wilhelm]

Phil,

The loss in coax (especially a long run) *will* reduce the SWR measured 
at the shack end.  If the loss is great enough and a fault is far enough 
down the coax line, the  measured SWR can be quite low, even 1.0:1.  In 
other words, the SWR at the shack end will always be less than at the 
antenna - just how much lower depends on the loss in the coax.

73,
Don W3FPR

Re: [Elecraft] K3 problem

  David,
Have you followed the steps in the manual for this error?  If not, do 
that first - let the K3 warm up before doing this calibration..
If it persists, try doing the Reference Oscillator calibration (use 
method 2).

So in effect, you're loosing your modulation as if the mic. came loose.
Can you get a carrier when keying or is it just SSB that's acting up?

I was thinking the same thing. I never go above 15 CMP. Mic is set to 30 and I 
easily get 100 watts PEP.

I would think a CMP set to 30 the receiving station could hear spiders crawling

I agree and have my cmp set to 13 and mic to 30 and I get good audio
reports which I consider something of a miracle!

Last night I tuned across 15m for a bit and there were some signals with
very bad audio.  One was so poor that after a couple of minutes I still
didn't know what his call was.  He wasn't getting any answers which
should have been a clue.

A little is good.  More is not always better!

Re: [Elecraft] K3 Problem

[Fred Jensen]

I don't do much SSB but when I do I get 10 dB peak compression with the 
CMP set at 12.  I use a Heil Proset with the electret mic I got from 
Elecraft.  I regularly get unsolicited comments of "really good audio." 
  My TX equalizer is set to the "K9YC recommendations."  I can't imagine 
what it would sound like at CMP=30, but I bet it wouldn't be good.

Re: [Elecraft] K3 Problem

Include me in that sentiment.  I have several times monitored my audio 
while adjusting the compression.  CMP=20 gives great audio quality and 
CMP=25 gives great contest audio.   CMP=30 generates significant audio 
artifacts without any better intelligibility.   In my opinion, CMP above 
30 merely adds trash to the bands.

Re: [Elecraft] K3 Problem

[Keith Heimbold]

I operate my K3 with compression of 14 and mic gain at 34-38 depending on 
conditions and environment (contesting, DXing or ragchewing). With the Yamaha 
MDE-100 microphone I get good audio reports. Guess each microphone has slightly 
different settings for optimum Audio quality.

My threshold for "crap" is a little lower.  CMP=20 is fine, the
audio gets "rough" much above that and by CMP=25 it is badly
distorted (even with PWR=0 so it's not RF feedback).

Re: [Elecraft] K3 Problem

[Lu Romero]

Yes, I also agree that CMP 30 is a bit much.  On my rig, the
"open ragchew wide dynamic range" setting is 18 and the "in
your face contest compression punch" setting is 24.  Any
more than 25, and you start to reach the point of
diminishing returns in inteligibility.  I use the Yamaha
Boomset here, so other mike's milage may vary.

Also, pay attention to the mic level setting, which is also
important. Both settings interact grately. Set the mic level
first, then add CMP to the mix.  Not the other way around.

You shouldnt be afraid to light up all the lights on the
right side of the meter consistently with the last light
flickering with mod peaks.  This is really an amazingly
clean audio chain we are working with. But as in everything,
too much of a good thing is often detrimental.

IMO, K3's audio processing chain seems to like consistent
input levels (still wish we could have attack and decay
handles for CMP, Lyle!).  The more consistent the input, by
close talking, by keeping control of your voice, even if it
is a P5 pileup, by managing the overall gain of your audio
chain, and by keeping external noise down, the more
modulation density you will get from this radio without
sounding like something from Guns and Roses record.

Re: [Elecraft] K3 Problem

[Edward R Cole]

I run COMP=20 on my K3 with a Heil HM10-5 desk mic (older model I 
bought in 1998 with wide freq element).  Get great audio reports on 
SSB on either HF or 2m-SSB.  I have only modified Tx equalization for 
three lowest audio freq bands as mainly running conversational 
operating on a couple HF Nets and most operating is VHF+.

I checked my COMP on the KX3 and it is only set to 8 with the MH3 
hand-mic.  On FM I had reports of overdeviation so lowered mic gain 
to 15.  SSB mic level appears to work at that level without complaint.

Re: [Elecraft] K3 problem

[Vic Rosenthal 4X6GP/K2VCO]

Could the power supply be shutting down for some reason? Measure the PS 
voltage when this happens.


Also, try transmitting into a dummy load to eliminate possible 
RF-in-the-shack issues.

Re: [Elecraft] K3 problem

[Don Wilhelm]

Jim,

Check the power supply to see if it is shutting off - if it not that, 
try the K3 into a dummy load.  If the problem goes away with the dummy 
load, the most likely reason is RF in the shack.


I did not think I had a problem with RF in the shack until I recently 
tried working on 10 meters.  At power levels above 75 watts, the K3 
would turn off all by itself - but no problem into a dummy load, so I 
have to get some ferrite on that antenna.


If RF is causing it, take heed of the wealth of information for 
attacking it in K9YC's paper on dealing with RFI at 
http://audiosystemsgroup.com/RFI-Ham.pdf

Re: [Elecraft] k3 problem

[Harry Yingst via Elecraft]

As per the K3 Manual Rev D10, Page 70

ERR TXF Invalid transmit crystal filter bandwidth

The crystal filter selected for TX (with CONFIG:FLTX) is either too narrow or 
too wide.
You must specify a filter that is 2.7 or 2.8 kHz wide for CW/DATA/SSB, 6 kHz 
for AM, and 13.0 kHz for FM).


That being said it could be a mis-configuration, or possible Corrupt firmware

Re: [Elecraft] k3 problem

[Don Wilhelm]

Bob,

The list of error codes start on page 68 of the
K3 manual.
ERR EFX does not exist, but ERR TXF is valid - it says the filter 
configured for transmit is not valid.
That is relatively easy to see with K3 Utility - Configuration tab, 
Configure Xtal Filters.

The filter for CW, DATA, SSB must be the 2.7 or 2.8 kHz filter.
For ESSB it needs to be the 6Khz filter and AM can use either the 6kHz 
or 13kHz filter

And for FM it must be the 13kHz filter.

Is there any chance he has turned on ESSB mode in the menu and does not 
have the 6kHz filter installed?

Re: [Elecraft] k3 problem

[Don Wilhelm]

Bob,

He will have to wait until Tuesday - Elecraft is closed Monday.
In the meantime, he should look at what is enabled for his transmit 
filters using K3 Utility.  He needs to know what filters are installed.
There should be a sticker on the inside of the top cover indicating 
which filters are installed.

Josep,
Apparently the 100 Watt PA has been disabled. Go to "Config" (Press and hold 
MENU), rotate VFO B until you see "KPA3", then rotate VFO A to select "PA   
nor."
Remember, it is always a good idea to back up your K3 configuration. Use the K3 
Utility to do a Config Backup. If you ever have a problem, you can always 
restore the K3 from that configuration file.
Buena suerte!

A Ham friend has given me a old cable Serial-USB and it has worked.!! The K3 is 
now running again.! Very happy here so I don´t need to send it to Italy.!
Theres one thing I don´t understand and it is related with the PWR, I can see 
only 12W.! Why it´s not sending 100W like the first days I used it.? I does not 
go over 12W (?), Can that be due to high SWR.? The tuner has matched the 
antenna but...(?) Not 100W out by now, any tips.?
Thank you so much for all your help.!

Don't forget to power-cycle the radio after changing to "PA nor".
(any option that is installed and recognized at power-on must have a 
power cycle when you change it's install status).

Re: [Elecraft] K3 Problem Solved!!!!

[Don Wilhelm]

Mark,

I am glad to hear that you now have resolved the problem.  Sorry to hear 
of your frustration, but those computer COM port issues can indeed be 
frustrating at times.


The connection with the serial adapter cable to the P3 *should* have 
worked.  That means you may have to do some additional investigation.  I 
would first suspect the K3 to P3 RS-232 cable, or the connectors - make 
sure the jackscrews are properly fastened. Now that the crisis has 
passed, connect the K3 to P3 serial cable and connect your P3 to the USB 
to serial cable - then see if K3 Utility can find and connect with the 
K3.  If not, then troubleshoot that particular problem.


I would also suggest that you obtain another USB to serial adapter - 
preferably one with an FTDI chipset.  You should have a couple of USB to 
serial adapters on hand to use.  It is always good to have a spare to 
use just as a check - they are not that expensive and serve as good 
insurance when you can try an alternate.
I recall that you initially tried loading the firmware through a 
Microham device - that is a "NO-NO", disconnect the Microham and connect 
directly through a proper working USB to serial adapter when loading 
firmware.


I do not know anything about Windows 10 yet, but I recall reading 
somewhere that it is not always consistent in the COM port assignments 
when using USB to serial adapters - perhaps that was part of your 
problem - determining the correct COM port to be used in K3Utility.  
Yes, K3Utility can *usually* detect the correct COM port, but there are 
some occasions for 'false positive" responses that can occur when it 
does a port search, so it is best to determine which COM port your 
operating system has assigned for your USB to serial adapter and tell K3 
Utility to use that COM port.
In prior versions of Windows, it was as simple as going into Device 
Manager and looking at the Ports - unplug the adapter to see which port 
goes away, and then plug it back in and see which COM port is assigned 
to that adapter.  Windows 10 may be a bit different, but something 
similar should exist.


Howard may or may not see your post to the reflector - I don't know if 
he monitors the reflector in his "off hours".  It would be best to send 
him a direct email.  At this hour, he should be off enjoying his 
weekend, but I don't think he would not leave a customer "hanging" if 
you have had prior communications with him.

The one time that doesn't work is if the K3 is in manual 
firmware-download mode, perhaps due to a failure of a previous download. 
 For that, the P3 should be bypassed.  The easiest way to ensure that 
is to unplug its power connector.

Re: [Elecraft] K3 problem "ERR DLL"

[Don Wilhelm]

Rys,

The first thing to try are the steps indicated in the K3 manual listing 
of errors.


If those do not help, and this is an older K3, try removing the front 
panel assembly (the KDVR3 manual page 7 has good instructions for doing 
that).  If the pins on the front panel connector are tin plated, they 
should be replaced with the gold pins (Elecraft has a kit).  In any 
case, removing the front panel assembly and simply replacing it will 
wipe oxidation from the pins and can restore proper operation.

Hi,

Are you sure that message wasn't "ERR PLL"? Do you have the older synth? It
has a PLL (phase locked loop) in it so that error message might make sense.

Re: [Elecraft] K3 problem (vfoB knob problem)

[Geert Jan de Groot]

The A and B knob each have identical encoders that use plug-in boards to 
the front panel PCB. Chances are that the encoder isn't connected 
anymore (got loose).


Opening up the front panel should tell. Note that the A and B encoder 
are identical so you can swap them for testing.


Note that assembly of the front panel is quite fussy with distance 
rings, etc. You are well advised to keep notes of how the front panel 
was assembled when you take it apart. It also makes sense to have the 
assembler's manual at hand.


Recent adventures with swapping parts on an older K3 learned that the B 
encoder sits in a little deeper with the new VFO-B knob. As a result, in 
my case, the solder pins were touching (scratching) the front panel PCB. 
I fixed this by cutting the jumper pins flush and putting in some 
isolation, just to be sure.


I don't expect any broken parts, but some disassembly required. When you 
disassemble / re-assemble, be GENTLE with the volume knobs, they are 
known to split on older serial numbers.

I tuned into my inv-V with 8 Watt on 3.63 Mhz and
connected a 1 meter wire as antenna on my HP frequency counter.
The counter displayed 3.2177 Mhz ! An offset of approximately .412 Mhz

Still no idea. Waiting on k3support@elecraft...

Problem solved!
FTP does not work here anymore due to unknown reasons.
As a result, a much older version of firmware has been installed.
For some unclear reason I kept the old firmware files. But now I moved them
to another folder. I received the latest firmware via email.
After installation, everything works as it should.

Thanks Elecraft/Wayne!

Re: [Elecraft] K3 Problem during transmission on SSB

[Luigi Casari]

Tnx Wes and Scott for your replay,

I connect a dummy load and I transmit on different bands.
The problems is on 21,24 and 28 MHz band.

To times when I push the PTT of the microphone the power is low and then gets 
up.

Don't believe is a problem of return RF as Scott suggests me.
When I have seen the first time the problem were doing DX in 21MHz, I used the 
PA and I get lots of compliments for the modulation. 
If they had been a RF problems with 1 KW the modulation has been distorted or 
with strong noises.

Seem more a false contact from some part.

This evening after the work I will try with K3 Utlility and I will check the 
connectors.

73 to all.

Luigi,

You might try running into a dummy load and see what happens.  If you 
still have the issue use the utility program and run the TX power calibration.  
If that fails, then you may have an intermittent issue the same as several of 
us have had.

One issue seems to be the "2D connector" at the right rear of the radio 
that connects the output filter board to the chassis.  This is the only ground 
return for the output connector.  Make sure the screw is tight.  It is the one 
that runs from the side panel completely though the 2D connector to the circuit 
board.

  Ragards to all,
  I have just discovered a problem, 28 MHz or 21 MHz SSB, during 
transmission 
  the power drop down to abt. 10/15W.

  This after few second of transmission, the power staies low for some 
seconds 
  and then increases again. No question of microphone, I have tried 
with MC85 
  and Pro set, also change the levels of the mic gain and compressor 
without 
  result.

  I have tried on other frequencies and have not been able to recreate 
the 
  problem, only in 21 and 28 MHz.
  Don't believe is a problem of SWR and some protection what limits the 
power, 
  the antenna is the same from the 10m to the 40m, Opti Beam, and the 
SWR 
  where have done the tests are low. Also the internal SWR meter of the 
K3 
  give me low SWR.
  Even in 160m, 80m or 6m with others antennas no problem.

  In FM mode I don't notice any decrease of power, 110W constant.

  Some idea?

Re: [Elecraft] K3 Problem during transmission on SSB

[Scott Ellington]

I agree that, if the same problem exists with the dummy load, it's not RF 
feedback.  (Especially the audio is OK with an amplifier and antenna.)  A poor 
connection is the must likely suspect.

Re: [Elecraft] [K3] Problem w/front panel switches

[Jessie Oberreuter]

  I had the same experience several months back.  Tracing it down, I 
found that one of the encoder push-buttons had internally semi-shorted to 
ground.  Each front-panel switch essentially acts as a divider tap, so the 
semi-short ended up shifting the effective tap point of every other switch 
on the panel.  I snipped the offending switch lead, and all was fine.  As 
a CW op, having that knob permanently set to cw speed hasn't been an 
issue, but I do intend to send the rig in for a full replacement of all 
four switch/encoders as soon as my KX3 arrives :).  (When I contacted 
Elecraft for a replacement part, I was told that I should just have all 
four replaced, as the switch/encoders they are using now have a much nicer 
feel than the first gen ones used in my #286 K3, and I would notice the 
difference in feel between a single new part and the old ones.)

Re: [Elecraft] [K3] Problem w/front panel switches

[Fred Jensen]

Well Phil's problem isn't mine, and I'm not even sure I have a problem, 
but my K3 switches are a bit erratic.  They don't do things other than 
what they should do, they just don't always do it reliably.  Going to TX 
TEST, I'll often get a mode switch as if I tapped it instead.  Others 
are sort of the same.

I have a hard time keeping the radio stable on the shelf, it really 
isn't all that good for protection against gravity outages [like an 
SX-28 was :-)], and it does move.  I think I need to figure out how to 
get it really stable first.  Then we'll see.

Re: [Elecraft] [K3] Problem w/front panel switches

[hawley, charles j jr]

Get a roll of 3M super strength moulding tape at your local auto parts or farm 
store. Comes in a red package. Two different widths. It's a grey double sided 
sticky tape and leaves no residue if you remove it. It's intended for sticking 
mouldings onto the sides of cars.
 I cut a little square of about 3/8 ths inch and put under at least the two 
front feet on the K line stuff to keep everything from moving. It's good for 
sticking an outlet strip to the desk, etc. Won't hurt the paint and can be 
removed by rolling it off with your finger. Do not use too much like a whole 
strip of it, because it'll take a large force to break a large strip loose from 
say sticking an outlet strip to a formica desk. A little dot here and there 
does it.

Re: [Elecraft] [K3] problem with Transmitter Gain Calibration

[Don Wilhelm]

You could try doing it manually to  "jump-start" it.  You have to do 
each band separately.
At least you could try that, and if still not successful, call support 
tomorrow (after 8AM California time) and they will walk you through the 
setup and/or assist with your problem.

Re: [Elecraft] [K3] problem with Transmitter Gain Calibration

[Wes Stewart]

I've had this happen several times after the output power disappeared.

It appears to be that the RF ground return to the output connector is completed 
through the "2D" block at the upper rear of the K3 (as viewed from the front.)  

If I'm wrong about this I'm sure a response will be forthcoming, but my 
experience has been that loosening the screw(s) and "scrubbing" the interface 
to the output board (no ATU in my K3) and retightening will fix the problem.  
Until calling the next DX station that I need for a new one, that is.

Re: [Elecraft] K3 Problem in Assembly, need advice

Hi Brian,

this measure point is the output terminal of a 5V voltage regulator (U12 
MC7805ACT).
A value of 445 ohms is not alarming. A matter of tolerances in all parts 
connected to this point.

But I expect Elecraft will react too.

Sounds like the offset is zero instead of the value indicated on the 
filter label.  Check CONFIG:FL  FRQ for the 2.7 kHz filter, or use K3 
Utility.

Re: [Elecraft] K3 Problem: Blank display & Won't turn OFF

[Rick Bates]

Roger, 

Do you have a KAT500?  It must be ON before booting the K3.

Does it say MCU LD on the display (may be unlit, use a flashlight)?  Then
reload the firmware.

The COM3 busy may (probably does) require a reboot of the computer.

Try disconnecting the serial port.  Since the computer hung that port out to
dry, it may be toggling something that denies the K3 the ability to boot.

While loading new firmware into the KPA500, something happened to my K3.
The firmware load to the KPA500 appears to have succeeded, but now the K3 is
ON with a blank display, the K3 won't turn OFF and the K3 Utility says that
"COM3 is being used by another application".  It looks like I've lost my K3
firmware and cannot access the K3 in any way.  Wow, what a mess!  I tried
turning things OFF and , then, ON again to no avail.

What happened?  And what can I do to get the K3 to identify itself and work
again.

Re: [Elecraft] K3 Problem: Blank display & Won't turn OFF

[Matt Zilmer]

To put your K3 back into a usable state:

0.  Kill the KPA500 utility program.  This should leave your COM3 free
for the K3 utility.  If it doesn't then reboot the computer.

1.  Remove the K3 power and leave it disconnected for 15 seconds or
so.

2.  Re-connect K3 power and hold the K3's power switch down for 10
seconds, then release (might take a little longer).  To be sure the K3
is in a force-load state, look at the display.  It should have the
backlight off and MCU LD showing.

3.  The K3 is in a "force-load" mode now.  Bring up your utility and
reload firmware.  

Best to contact Elecraft support so that they can help figure out what
happened.

Re: [Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3

[Thomas Norff]

Joe,

have you checked the 'internal information '  ?

-
use:

OM * (Option Module Query; GET Only)
RSP format: OM APXSDFf-; where any of the letters APXSDFf, if present,
indicate installed and detected
option modules (see list below). The positions of the letters are fixed. If
a module is not present, its letter is
replaced by a dash (-). For example, if only a PA and sub receiver were
installed, "OM;" would return "OM -P-S--
--;". The five dashes at the end are reserved for future module letters.
Option List: The letters (and associated positions) in the OM string refer
to the following option modules:
A = ATU (KAT3), P = PA (KPA3), X = XVTR and RX I/O (KXV3), S = Sub Receiver
(KRX3), D = DVR
(KDVR3), F = Band-Pass Filter module, main (KBPF3), and f = Band-Pass Filter
module, sub (KBPF3).
--

During initialisation all installed modules are detected ... independent
what you have configured 
If your module is dead i would expect this to be reflected in the OM output.

Re: [Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3

[jmalloy]

Thanks for the suggestion, Ed, but I don't see any hint of carbon on 
either the plug or the receptacle pins that connect the KPA to the rest 
of the radio.  Do you know -- or does anybody know? -- what sort of 
"quick check" of voltages I could measure to check whether the KPA is 
functional?

Thanks again, Ed!

Re: [Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3

[Bill W5WVO]

Dick,

I experienced this same problem exactly on my SN 888, complete with 
intermittency of the symptom. After some consultation with Elecraft tech 
support, they sent me a KPAIO3 board -- the board that the KPA3 connects 
through 
and that contains the 12VDC sensor circuitry. Unfortunately, I haven't been 
able 
to get to installing it as yet. It's on the list for when I return from holiday 
vacation out of town. My bet is that this will cure the problem. I'll let the 
list (and Elecraft tech support) know when I swap it out and try it. Should be 
first week of January, possibly end of December.

Re: [Elecraft] K3 Problem: ERR 12V and failure(?) of KPA3

[Thomas Norff]

... as always Dick is right ... one nice command lost ... at least for me

Joe,

do you get any ERR ... displayed after switching-on the K3 ?
If not the installed KPA is responding to the internal commands.

Did you check the relay as described in the installation manual of the KPA
--
Connect a power supply to your K3 and test the fans and KPAIO3 interface
control as follows:
Press the POWER button to turn the K3 on.
Hold CONFIG to select the Configuration menu, then turn VFO B to KPA3.
Normally, the display will
indicate NOT INST (not installed).
Turn the VFO A knob to PAIO ON, then turn it further to PAIO TST. When
moving between ON and
TST, you should hear a relay click on the KPAIO3 board. If you don't, press
the K3 POWER button to
switch it off, then on again and retry the test.
Turn the VFO A knob on past TST to FN1, then FN2, FN3 and FN4. The fans
should start turning at
FN1 and increase speed as you continue to FN4.
Turn the K3 off and disconnect the power supply.

RE: [Elecraft] K3 problem with logging program after download upgrade

[Dick Dievendorff]

Hi, Buck.

The K3 Utility attempts to communicate with the MCU initially to establish
its baud rate.  This is done by sending a small command at each of the
supported speeds.  If the MCU responds at one of those speeds, the baud rate
is saved and an attempt is made to restore that setting after firmware load.
Firmware loading is done at 38,400.

If the K3 Utility can't communicate with a "live" MCU (which can happen if
you've pressed and held the power key for 10 seconds), then the established
baud rate can't be determined, and the K3 Utility leaves the baud rate at
38,400 after loading firmware.  Since the utility couldn't figure out the
initial baud rate, it can't reestablish it after the load.

Is this repeatable, or a one-off occurrence?  I test this, and I don't think
I've changed that behavior recently. While typing this note I set the baud
rate to 4800, loaded the MCU and DSP1, and found the baud rate back at 4800
after the load. 

If any of the firmware loading is interrupted and the K3 Utility doesn't get
to the end of the firmware load and have a chance to restore the baud rate,
it'll be left at 38,400.

The intent is to restore the baud rate that the rig was set to before the
firmware load.  If all goes well, that usually happens. But interruptions
can upset that behavior.

Also, the Mic Sel of Line In stopped working.  Once I cycled through  the
other choices back to Line In, it started working again.

RE: [Elecraft] K3 problem with logging program after download upgrade

[Dick Dievendorff]

No, that sounds like you got a bad file from the Elecraft file server.  I'd
recommend erasing the hmcu*.hex file and re-do the "Copy files from
elecraft".  If you open the hex file in Notepad, every line should start
with a colon.

Hi, Buck.

The K3 Utility attempts to communicate with the MCU initially to
establish its baud rate.  This is done by sending a small command
at each of the supported speeds. 

Soapbox ON.

IMO - This is a tragic WASTE of BITS.

And this happens every time there is an update?

Calculate the number of updates over the life of the
radio, now how big is the bit bucket - remembering
ASCII is 7 bits per character plus parity plus start
bits and stop bit.

Could be some major overflow problems when folks least
expect it...

Huh? The command is one byte, a semicolon.  There are four supported speeds.

Surely the uploader should do some kind of integrity check, instead of
attempting to upload a duff file to the radio? It's not exactly rocket

Thanks, Bob.  But I didn't detect the corrupt file problem until after the
K3 Utility had started to load the MCU.  I still think I might need to pass
the file twice, once to verify that it's complete and checksums correctly,
and then again to actually load the firmware into the radio.

Well,  From the error message I infer that the file is in Intel Hex

an integrity check - and detected a problem. Relax, these guys *do*

Could it be that years from now, when debate rages over the relative worth of a 
low serial number K3 versus a high serial number, or positive or negative ALC,

of the best tone for sidetone that it will return to us for visitation?

I just realized that all the posts about the K3 have displaced the old threads 
that cast aspersion on those that didn't build their own Elecraft rig in the

comfort of their personal work shop.

I suppose I will have to overcome my guilt when my K3 arrives, since it is 
factory built


I also heard a rumor that Christams will be celebrated in March of 2008, thus 
freeing the elves to assemble K3s and Santa can deliver them.

RE: [Elecraft] K3 problem with logging program after download upgrade

[Dick Dievendorff]

Julian makes a good point, but we're not going to use MD5.

The intel hex format contains sufficient internal integrity checks that we
can very likely tell that it has been corrupted. It has a line-by-line star
character, a per-line checksum byte, and it has a definite end of file
record.  The sorts of corruption that we'll see in file transfer operations
will most likely be caught by the existing verification.

However the K3 Utility wasn't verifying the file until the MCU load had
started.  This is inconvenient, because the error recovery then consists of
erasing the corrupt file from your PC, re-doing the FTP, and trying it
again.  If the FTP operation is at some distance from the radio, it becomes
more inconvenient.

The current DSP files are in a binary format, and the load process depended
on a post-load internal verification, plus a command query to see that the
processor was healthy enough to respond to a few simple commands.

Based on K0PP's experience, the next revision of the K3 Utility (being
evaluated by Field Test now) will verify Intel Hex files right after FTP
copy, repeating the file copy if necessary. It will be verified again by a
pre-pass before beginning the MCU load.  

The loader contains changes that permit the DSPs to be loaded in either
binary or intel hex format.  Subsequent revisions of DSP firmware will be
released in intel hex format to permit this verification.

The DSP firmware files are larger (> 2 times larger), but the load time to
the K3 isn't increased dramatically.  It will be slightly slower.

Use of MD5 would have required us to maintain a side file of MD5 hashes or
create a new variant of the intel hex file format with an internal digest.
I suggested that keeping the side files in sync with the distribution of the
firmware would be a continuing distribution problem.  I did use an internal
digest technique (with a CRC-32) for the configuration file save format, but
that format was one of my creation.  intel hex files are processed by a fair
number of existing tools, not all of which are easily modified.

MD5 is overkill.  It's intended to detect deliberate tampering, although
it's also useful as a fast way of comparing multiple files, as there is 
a high level of confidence that files with the same MD5 digest have the
same content, given the presumption that they might.  It's origins are 
in encryption, rather than in error detection.  CRC codes are faster to 
compute and give good protection against random errors.

In general, all the high risk steps in getting the firmware from 
Elecraft to the K3 are protected by error detection codes already, with 
the exception of the final hop, over the serial link.  Typically the hex 
file is going to be processed incrementally as it arrives over that 
link, so most of the protection at that stage has to by short check 
codes that can be applied frequently, not a long one for the whole file.

The other high risk area is probably the PC memory, if it doesn't have 
parity, which most, for cost, and speed reasons, doesn't.  However, if 
the PC memory unreliable, you cannot trust that error detection code is 
being run correctly, or that errors won't be introduced after the check. 
 Similarly for CPU faults, although these should be less likely for 
a system running within specification.

Incidentally, there are known problems in MD5's tamper detection 
credentials and best current practice, at least in the open literature, 
is to use both MD5 and another cryptographic checksum algorithm called 
SHA (secure hash algorithm).

parity, which most, for cost, and speed reasons, doesn't.  However, if 
the PC memory unreliable, you cannot trust that error detection code is 
being run correctly, or that errors won't be introduced after the check. 
Similarly for CPU faults, although these should be less likely for 
a system running within specification.


Incidentally, there are known problems in MD5's tamper detection 
credentials and best current practice, at least in the open literature, 
is to use both MD5 and another cryptographic checksum algorithm called 
SHA (secure hash algorithm).

Re: [Elecraft] K3 Problem, VFO Noise While Rotating On 10 Meters

[Randy via Elecraft]

Hi Paul Thanks for the reply. I have the upgraded SYN-3A synthesizer and the 
rig came from the factory with the resistor and diode mod installed.  The clock 
rate is set to SP2. I should have mentioned that info in the original post. 73

Re: [Elecraft] K3- problem with no text on psk31, 30 meters

[Lyle Johnson]

There are four submodes of the DATA mode.  If the T is present, it 
indicates one of the text decode modes is active (AFSK A, FSK D or PSK 
D).  If the mode is DATA A, then the T is no longer present.


When in DATA mode, hold the DATA MD button to display the DATA submode 
and rotate the VFO B knob to select the desired one.


If you are operating PSK31 using HRD, then you want to be in DATA A 
mode.  The PSK D submode is for use with the K3's internal PSK decoder 
and use of a CW paddle for sending PSK.

Re: [Elecraft] K3-Problem with DX spot point-&-click and ACLog

[ab2tc]

Hi,

I highly recommend Ham Radio Deluxe. It supports the K3, Simon - the author
- is a K3 owner and supporter. Pointing and clicking on a DX spot or on a
frequency dial works great. I use it in conjunction with LP-PAN and
LP-Bridge. Pointing and clicking on the panadapter display also works
flawlessly and instantly. Whenever the K3 adds new remote control features,
Simon is there supporting them within days.

I've noticed that from Scott one before when I made a similar request.  I did 
what 
you did.stopped using it and went to another program.  I also no longer 
recommend 
that program to anyone for that reason.  I think that's a mistake on his part 
not to 
support the K3.  Oh well...

Check out N1MM for contesting.  It's free, and it does much more the ACLog.  
For 
general logging, try HRD.  It has a nice log and great K3 support.

Re: [Elecraft] K3-Problem with DX spot point-&-click and ACLog

[Jeff Wandling W7BRS]

I'll keep my fingers on the VFO.  I can't go HRD path.

As far as ACLog..  Ugh.

The way for him to solve the problem is to make the source GPL'd. 
There's a fair number of technical people on this list who would be able 
to patch his code to make it work.


Everyone benefits, including him by being able to sell the improved code 
base with the premium features obtained by paying the fee.  He wouldn't 
lose a dime*


I don't know why he doesn't GPL it.  *The trial license featue is easily 
worked around by simply re-installing the software.

You bet I'll keep my fingers on the VFO. For regular tuning up and down the
band, in my view there is no substitute for a tuning knob. But point and
click is very convenient for cluster spots and fast QSY in general.

Unless people voluntarily assign it to him, he would not own the 
copyright in any modifications, so he would not be able to sell 
copyright licences (or the actual copyright).  He can still sell the 
service of putting it onto media, or otherwise distributing, and for 
support, but anyone else would be free to do so.


He could also use changes to understand where problems lie, and make his 
own changes to fix the problems, but would need to be careful to avoid 
any accusation of copying.  He would still own the copyright in his 
original work, and could licence it, or derivatives of it, under any 
licence he likes, in parallel with the GPL.


(Exception: trivial and obvious changes cannot be copyrighted.  I 
believe the Free Software Foundation (FSF) uses four changed as the 
measure of what is trivial.)


This is not to say that using the GPL would be a bad idea, just that one 
needs to understand the limitations.


Note: the FSF believe that assigning copyright requires a formal 
contract, and make a token payment (USD 1) for copyrights assigned to 
them.  Assigning means transferring ownership of the intellectual 
property, losing ones own rights in it.

Terry and All,

Hmmm!  Sure doesn't sound like the Scott I've been dealing with for 8 years? 
10 year?  I have been using his ACLog program for all that time, and he has 
always been very cooperative.  I would add, however, that when I inquired if 
he had ever thought about offering an adaptation of his logging program for 
use on a Pocket PC, he indicated he just hadn't had the time to consider 
doing that, and wasn't sure when and if he could.  But he was nice enough 
about it.


I rather suspect you caught him on a bad day, or possible there was 
something conveyed in your original conversation with him (which we don't 
really know the content of) that might have come across not quite as you 
intended.  My wife says I can be that way sometimes, even though it isn't on 
purpose.  With some 2000 K3's out there in the bushes, and a lot more 
coming, I would think Scott might see the benefit of having a K3 version.  I 
have no idea if he really follows the Elecraft success story though. 
Possibly if he hears from more of his customers who now use K3's, he might 
be persuaded to give it more priority.  So, for whatever good it might do, 
I'll drop him an email indicating how much I hope he can find time to 
accomodate us.  It will take a lot more than just me to have any impact 
however.  By the way, I have been inclined all these years to recommend 
ACLog anytime someone asked.  Maybe the way to get Scott's attention is to 
ask him if future recommendations should contain a caveat that not all 
features of his program will fully integrate with K3's as they do with other 
transceivers.  Maybe I'll try that approach, but very tactfully (I hope).

FWIW.

Well I spoke with Scott, N3FJP regarding the problems I had with the K3 
and
his ACLog logging program.  Although there is a radio selection for 
Elecraft

in his CAT software he says it does not support the K3.  I offered to help
him (which I've done before) but he said he was afraid if he made changes 
to

ACLog for K3 support it could harm the functionality with other Elecraft
rigs.  Matter of fact, he got quite curt with me when I sent him the
Elecraft Programmer's Reference:

W0FM:
" Thanks Scott.  Would having the Elecraft K3 Programmer's Reference be of
help? "

N3FJP:
" No, again, "fixing" the K3 may introduce problems for other Elecrafts.

73, Scott
N3FJP"


Looks like I'll be shopping for a new logging program.

RE: [Elecraft] K3-Problem with DX spot point-&-click and ACLog

[Terry Schieler]

Hi Dave (W7AQK) et all:

You are correct, Dave.  I have been a strong supporter of Scott's logging
software for many, many years.  I spent a great deal of my own time working
with him to get ACLog to work with my (then new) FT1000MP.  We finally got
there, and it worked flawlessly ever since.  That is exactly why I was so
surprised with Scott's reaction to my offer to help with the implementation
of the K3.  What the heck, it's almost the same basic framework as the K2,
which he has implemented.

I watched curiously as Scott's attention turned to weather forecasting
software and some other projects just a bit "outside the box" in my mind.  I
was a huge proponent of ACLog specifically because of Scott and Kimberly's
great support for the program and recommended it to everyone (see my posts
on eHam.net).  That is exactly why I felt like Scott brushed me off when I
had specific questions about the K3 interface.  To me, it sounded like he
was saying "I'm not going there".  Perhaps he's too busy, perhaps he has
developed other interests, and, like you say, maybe I caught him on a bad
day.  I don't know.  But as someone who has helped him promote his product
in the past, and offered to do it again, who is then rebuked, I don't know
what else to think. (Insert typical:  "I have no financial or business
interest in ACLog" here.)

Again, you are, indeed, correct.  It sure doesn't sound like the Scott that
I've dealt with for many years.  But how do you do what he does in light of
the huge success of Elecraft's K3?  

I have since sampled some very nice logging and CAT software to which I
wouldn't have given a moment of thought to until now.

73,
Terry, W0FM
