[Elecraft] Elecraft K4 Operating Manual

For those of us that like to sit in a comfortable chair and read a printed 
version of the Manual, is it possible to post a black on white version?  It 
would save a great deal of black ink?

[Elecraft] K3 Filter Settings Main and Sub Receiver Track For Data Mode Only

[Elliott Lawrence]

Using the latest K3 firmware MCU 5.35 for my K3 (not K3S). In the Data mode 
only, setting the bandwidth of the main receiver also causes the subreceiver 
bandwidth to track and be identical. The BSET control XFIL for Data has no 
effect.  In CW and SSB modes the main receiver XFIL can be adjusted and the 
subreceiver XFIL changed independently using BSET.  This was definitely not the 
case for previous firmware versions.   This operation is not band dependent.

I have checked all of  the firmware notes and the latest K3S manual and can’t 
find anything to explain this operation.  Am I missing something?  Is this a 
new and unwanted improvement?

Thanks for your comments.

Re: [Elecraft] Configuring a K3 for the PR6-10

I would suggest that you get the appropriate male-female gender changer cable, 
remove pin 11 from that part and install it in series with the KPA500 cable.  
Keeps the original cable intact.

 Hi Ted,
 
 If you are using a KPA500 and a PR6 you will have to remove pin 11 from the
 cable that goes to the KPA500. It has popped up on this reflector once or
 twice but it is not mentioned in either the PR6 or the KPA500 instructions.
 If you wonder if this will work just pull the 15 pin cable off of the KPA500
 and you'll see that the PR6 works as you would expect it to work.

 I need to ask for help configuring a PR6-10 on the K3.  Installed OK,
 removed the internal jumper per instructions and am using the control line
 on a Y splitter to allow the KPA and KAT to connect to the K3 as well.
 Physically, all seems fine, and the K3, P3, KPA and KAT work just as they
 always did.
 
 Then to operate the pre-amp I configured digout1 to ³on² for 28 Mhz on the
 K3, per instructions.  OK so far.
 
 
 The PR6-10 manual says ³Tap RX ANT to enable preamplifier.²  When I do so
 the noise level goes way down and the signals disappear, as if there were
 no antenna connected to the receiver.   Removing the power plug from the
 preamp made no difference in either mode ­ RX ANT on or off.
 
 
 I recall when building the K3 that there were elections to be made about
 antenna configurations when installing the sub receiver and/or
 the KXV3.  I also remember that there are a myriad of ways the antennas
 can be routed via the configuration menus.  I have a feeling that the
 elections and internal configurations I originally made in the K3 are not
 compatible with getting the PR6-10 to work simply by pressing RX ANT, but
 I can¹t reason my way through it all.

program I was using when I first got the radio.  I’ve read and reread the 
operating manual and Fred Cady’s always helpful book with no success!!!  It was 
so long ago that I can’t remember what I did.

Any help would be appreciated.

Hi Ron,

correct, you'll loose the voice memories then. But you know there's 
PF1/PF2 for macros available on the front panel, too, right? Might save 
you from needing to assign to M1-M4 if 2 are enough. ;-)

It seems to me that having the macro available on the front panel is more

[Elecraft] KPA500 Chassis Issues

[Elliott Lawrence]

I just completed assembly of my KPA500 shipped last week. To everyone 
discussing problems with the fit of the top cover and distortion of the 
chassis.none found here.   Top cover is perfectly flat WRT the front 
panel.  Everything as usual for Elecraft products.  I followed the 
instructions to the letter.  Power turned on and all appears normal. To late 
in the day to finalize station connections but will make some RF tomorrow.

Re: [Elecraft] Power Supply?

[Elliott Lawrence]

How is it any different than plugging in the KPA500 to the ac line/mains? 
Elecraft has already done that.  Enough said.

 I can attest that obtaining UL, CSA and foreign
 certification for anything that plugs in is an involved
 and costly process.  I went through the process a few
 years ago with a medical product, and I can understand
 why Elecraft might want to avoid marketing AC PSU's.

[Elecraft] KPA500 to K3 ACC Connector

[Elliott Lawrence]

Can any of the field testers using the ACC Connector interface verify if the 
K3 end of the cable has a through mounted female connector (back to back 
male/female conncectors) that the mating connector for the PR-6 pre-amp can 
use for access to pin 11 without having to make any wiring changes?  This 
would also enable access to the other K3 functions and the KPA500 
simultaneously.  If not, sounds like a good option to me!!

is a 3 contact miniplug.  Thought that it would be a 2 contact (tip and sleeve) 
since that's all that is needed!!

Re: [Elecraft] PR6 6 meter antenna connections

Subject: Re: [Elecraft] PR6 6 meter antenna connections


 Don't feel alone, Gil.

 I went through the same head-scratching several months ago, when I bought 
 my PR6.

 connection is actually quite simple.

 Your 6 m antenna connects to the HF antenna jack on the back of the rig 
 ( ANT-1.)

 Connect the 6 m preamp to the receive only bnc jacks on the transverter 
 interface.  connect  12 V power to the preamp using the supplied RCA plug 
 that goes into the auxiliary 12  RCA-style 12 V jack on the back of the 
 rig, enter connects to the preamp with the small 3-pin  connector attached 
 with red and black wires to the RCA plug. Make sure it is oriented 
 properly; the red wire goes toward the rig and the white wire away from 
 it. The plug is not polarized, so it is possible to put it in backwards. 
 No harm if you do, but the preamp won't work.

 You have one additional setup question to deal with. Do you want to preamp 
 to be powered whenever the rig is on, or only when the rig is tuned to the 
 6 m band? If always on is your preference, your setup is done. If you 
 want the preamp to be powered only when the rig is tuned to 6 m, then you 
 need to remove the jumper from J2  (see  instruction manual),  and connect 
 the supplied db-15 connector with one  white wire coming out of it to the 
 AUX
 DB-15 jack on the back of the rig. Go into the config menu  and set 
 DIGOUT1  to on with the rig tuned to 6 m, and to make sure that DIGOUT1 
 is set to off for all other bands. That  configuration will power up the 
 preamp when you switch the rig to 6 m.

 To engage the preamp,  simply tune your  rig to the 6 m band and press the 
 RX ANT button on the front of the rig,  (near the power button). When you 
 do that, the K3  will automatically route the receive signal to the RX ANT 
 module,  through the  6 m preamp, and back to the front to end of the K3 
 receiver.  When you transmit, the  rig  will automatically bypasses the 
 receive  antenna circuitry, and sends the transmit signal directly out 
 through the ANT-1  connector.

 For normal use on 6 m, you don't connect anything to the outboard pair 
 of bnc jacks on the preamp.   those basically exist to provide the receive 
 only antenna functionality for every band other than 6 m,   since the 
 preamp is bypassed when the preamp is  powered off.   in this mode, a 
 receive only signal goes directly from the outboard pair of BNC jacks to 
 the inboard pair that are connected to the rig itself.

 When you first hook this thing up, it's natural to assume that the 6 m 
 antenna ought to connect to the 6 m preamp, but it doesn't. The 6 m 
 received signal simply takes a little detour from  the main antenna input 
 jack through the preamp, and then back into the receiver. It's like 
 stopping at Starbucks for an espresso to give yourself a boost before you 
 go on a long trip (through the receiver).

 Hope this helps.

 Lew  k6lmp


 For the six meter PR6 owners and users;

  I've followed the factory guides on the PR6, no problems with
 installing it, but I'm totally befuddled about where the 6 meter antenna
 itself is connected! All the text does is refer to different K3
 connections, in terms that are fuzzy to me at best, bearing in mind that
 my brain is still fuzzed over from a case of the flu, and a lot of
 items aren't making sense right now anyhow.
   Would the experts in the group kindly give me an explanation of what
 cable goes where, to make this system work? The Elecraft tech support
 goes into a vernacular which makes little to no sense to a late '50s era
 beginner, before logic gates and bypass modes.
   Sorry for sounding like a babe in the woods, but I have almost no
 time for thinking things through, too many work items to accomplish with
 a spine that's telling me I'm nearly headed for a wheelchair!

Re: [Elecraft] New Firmware MCU 3.79

The firmware is NOT show as a 3r79.zip file and a brower refresh doesn't 
change the situation.  This is different from all of the previous releases. 
If you want to download and save version 3.79 you need to create a new 
folder and transfer all of the required files into that folder.  This will 
create an archive for previous versions.  Going directly to the Elecraft

 If you have K3Utility pointed to detect new firmware on the Elecraft FTP

 ... with DATA A mode you should be setting the input audio level to
 get 4-5 bars of ALC, then setting the Power out on the rig for the power
 level desired. If you do not have this level of ALC action, then the 
 radio
 tries to increase the gain to bring the level up...

 Exactly!

[Elecraft] Firmware Request

[Elliott Lawrence]

Boy the firmware changes keep coming and coming even before I can load the 
previous beta a new one arrives.

I would like to make a firmware change request.  Several times while in the 
Data A mode I have accidently hit the M1 button where I have a voice message 
of my call stored.  Of course before I can stop it my call is sent on the 
RTTY frequency out of band!!!  Not a good thing.

Please consider updating the software to inhibit the voice message or only 
use a CW message previously stored when in the Data Mode.  Actually having 
the CW message played in Data Mode would be good in a pile up as you could 
send your call without using the paddle and actually complete the QSO with 
only using the M buttons!!

Re: [Elecraft] Wow, what a piece of work!!!!

Does 3.47 eliminate the step/audio blanking with the NR engaged and the BW 
control rotated?

Subject: [Elecraft] Wow, what a piece of work


 Well, the CQ WW is over,  I'm rested and I finally got to play with 3.47.

From all the emails, there's not much left for me to test!!
 I did a few and it was a smooth, slick operation.

 I like the idea of an Aux bank of Programable switch that fits under the 
 K3.

 Question:
 Is there going to be any switches available on the P3 to control the K3??
 Speakng of P3, any news?

 Wayne, thanks for letting my test 3.47.
 And thanks for including the users in on all your development, planning 
 and
 options.
 What a concept!!

I also have noticed the audio blanking while shifting the WIDTH control

F4 settings.  I do not notice any audio blanking in the F5 through F8 
settings, however.  The fourth level settings in F1 through F8 are 
extremely low in audio output.Roy Morris  W4WFB

[Elecraft] K3 Firmware 3.44

[Elliott Lawrence]

I installed the latest 3.44 firmware and the associated DSP firmware 
yesterday.  The install went without a problem although I am always a bit 
anxious at the completion bars slowly march across the screen!

I've noticed with the NR engaged and the BW control being adjusted that the 
audio blanks as each step occurs (a popping sound). I don't remember that 
being there with my previous version 3.3.  The blanking does not occur with 
the NR off. It just smoothly changes the bandwidth.

Does anyone else notice this condition?  Is it a function of the changes 
made to eliminate the audio screech? So far everything else seems to be 
functioning OK.

Elliot,I installed my FW 3.44 yesterday and now that you mentioned I gave it 
a try and your are right,with the NR engaged, in my case best result at 
F4-1, every time I move the WIDTH step by step,I hear a pop sound at the 
speaker and the audio blanks out for a fraction of a second,no big deal for 
me but the WIDTH tunning is not smooth as it was before,all the other 
functions works ok,maybe Elecraft team will fix this with the next 
upgrade,that's why they want us the beta testers do all the test and let 
them know what is wrong,73

[Elecraft] K3 possible subject for firmware update.

[Elliott Lawrence]

I use a Steppir antenna here.  No problem tracking the frequency as shown on 
VFO A.  When I go split and therefore transmit on VFO B the antenna 
frequency is not updated for operation in a different band segment.  It 
still tracks VFO A.  On my previous radio, FT1000D, the freqency information 
followed the VFO selected for transmission.  Not a big deal since the 
antenna is reasonly flat even when not optimized for a different part of the 
band.

[Elecraft] K3 RIT Function

I have S/N 3381 up and running and trying to get used to all of the new buttons 
and knobs.  I'm enjoying all of the features and the especially the NR 
cabability.

I just found that I can tune the receiver using the RIT knob without the RIT 
button engaged and the RIT icon not shown on the display. This seems strange to 
me as I did not notice this before.  I'm using firmware 3.30.  Have I 
accidently engaged something when I pushed and held the PF1 button??

[Elecraft] K3 6M Question

[Elliott Lawrence]

I will be using my K3 driving  an Alpha 87A.  The amp operates up to 10M.  I 
am using a Steppir so the same antenna will be used for 6M.  The question is 
does anyone have any experience using the K3 barefoot through the 87A when 
it is off or in standby?  If it can't be used that way, I will need to come 
up with a switching scheme to bypass the amp.  I have a question in to Alpha 
but don't expect a reply until after the holiday weekend.

[Elecraft] New K3 Menu Setting

[Elliott Lawrence]

My new K3 is complete except for installing the some remaining filters and 
the KRX3.  I am in the process of understanding the functionality of all of 
the menu items and finding the various buttons!!

I will be using the K3 with the Steppir controller to automatically change 
bands as the radio is retuned.  I see that the AUTOINF entry needs to be 
changed to AUTO 1 to provide band data information on the RS232 port.  My 
question:  When using the RS232 port with the K3 Utility, does this menu 
item need to be returned to NOR for proper interface compatibility?

For anyone using the K3 with the Alpha 87A.  Is any setting for the TX DLY 
other than NOR 008 more optimum for proper QSK operation?

Thanks and 73

[Elecraft] K3 Mike connections

[Elliott Lawrence]

The mike jack connections as shown on page 13 are pin 1 audio, pin 7 and 8 
ground.  I assume that either or both ground pins can be used and their is 
no need to use one versus the other.  My experience with other radios using 
multiple ground pins is that one had be associated with the audio input and 
other for control purposes.  The isolation was necessary to prevent noise on 
the audio input.

[Elecraft] FOR SALE: KDSP2

[Elliott Lawrence]

I have a KDSP2 that was built and installed in January 2007.  I have played 
with it and find that it works fine. However, being an old CW op I prefer to 
use the anatomical filter between my ears!!

If you have a KAF2 and want to try the KDSP2 it will go directly in place of 
the analog filter.  If you haven't installed any filter you will need to modify 
the control board and order a 3 pin and 5 pin female header from Elecraft to be 
installed. In either case, you will also need to obtain a Gray Foam retention 
piece for the K2/100 and the Black Foam retention piece for the basic K2. These 
items shouldn't total more than 2 or 3 dollars.

The KDSP2 is perfectly assembled and tested.  I am a retired electronics 
engineer and 53+ year ham.  I am asking $220 shipped Priority Mail.

Please contact me directly.

something now that I don't recall see earlier.  After I finish transmitting and 
the display has shown the 5/6 tick marks their is approximately a 2-3 second 
delay of blank screen before the frequency is shown again!  Is this normal?

[Elecraft] Yaesu FT-2000 v K-3?

[Elliott Lawrence]

I am owner of  a K2 with all of the accessories etc.  Very nice radio and I 
enjoyed the build and operation of the radio.  I use an FT1000D as my main 
station radio.  I enjoy the 200w capability and 99% of the time I don't need 
my Alpha 87A.  In fact, a lot of the time after turning on the amp I work 
the station with the exciter before the 3 minute warmup period is over!


I am considering an FT2000D as a possible replacement for the 14 year old 
FT1000D but I intend to  wait a long time for Yaesu to get the bugs out of 
the software and hardware design.  I don't like being the test guinea pig 
for new equipment!  I had an opportunity to play with the K3 at the Visalia 
DX Convention.  The features are very impressive and the front panel is very 
user friendly.  I like the modular concept and would go the build it 
myself route when and if  I decide to buy.  I can't enough good things 
about the Elecraft design philosophy and customer service.


One thing that would help would be an additional option for a 200w capable 
radio  the K3D!!!  I wonder if that is a future possiblity??!!

Re: [Elecraft] Rework Eliminators: when to use them, and why

[Elliott Lawrence]

The pin jumpers are available from places like All Electronics for 50 cents 
for a 40 pin header.  Cut the header into appropriate lengths and solder 
jumper wires and caps/resistors across the correct pins.  Put the jumpers 
for the each mod in a small envelope appropriately marked and ready for use 
if necessary.


I can't see spending big bucks when $2 will do for something you will rarely

Subject: [Elecraft] Rework Eliminators: when to use them, and why


Gary and company have done a very professional job on the Eliminators. 
Some builders will find them useful. On the other hand, Elecraft's 
documentation and staging of construction is consistent and carefully 
planned, so they are not a necessity.


It's clear that builders can successfully complete the K2 using either 
method.


Here's my recommendation:

-  If the notion of plug-in substitutes for future options strongly 
appeals to you, and you don't mind *carefully* following the additional 
set of instructions that comes with them, then by all means consider this 
method.


-  If you'd prefer to minimize the amount of documentation you have to 
deal with in building a kit, then stick with the Elecraft manuals. If 
you're capable of building a K2, then you certainly won't have any trouble 
adding options our way.


Disclaimer: I'm the principle designer of the K2 and wrote most of the 
manuals, so I could be biased. You decide  :)

[Elecraft] KPA100 Upgrade

[Elliott Lawrence]

What are the specific incremental upgrade changes to go from C to D?  My amp is 
revision C so if I  wanted to make only those changes, what needs to change to 
make it a D?  The amp runs just fine as built

[Elecraft] KDSP2 Performance

[Elliott Lawrence]

I am thinking of adding the KDSP2 to my trusty K2.  I have listened to the .wav 
files on the Elecraft site and the reduction in ambient noise is impressive.  I 
know that the DSP is designed to handle random/thermal noise but can anyone 
comment on its actual ability to handle pulse/burst noise such as that 
generated by power lines etc.

Thanks es 73,
Elliott WA6TLA

Re: [QRP-L] Re: [Elecraft] K2 Frequency Display Problem

[Elliott Lawrence]

Just change bands before turning off K2.  The information is immediately
stored in the EEPROM without waiting for the 30 second timer.

  Help!  Yesterday, the frequency display on my K2 #5113 stopped
  functioning properly.  When I turned off the K2 I was on 14185.09.  When
  I turned the K2 back on later in the day, it read 14063.  Now, every
  time I turn the radio on, I see 14063 on 20M no matter what frequency I
  was on when I turned it off.  Same problem on every other band, no
  matter what frequency I was on when I turned off the radio, it turns
  onto a particular frequency when I turn it back on, for example,
  18143.90 on 17, 7241.09 on 40.  Any ideas on how to fix this?

 The K2 manual says:

 Backup Timer

 While you're moving the VFO, a 30-second data backup timer is
 being continuously re-started. Once you have completely stopped
 tuning the VFO for at least 30 seconds, the K2 will then save your
 current operating frequency in EEPROM. As long as you stay on a
 particular frequency, no further updates will be done.

 ... so the simple answer is wait 30 seconds without tuning, you
 impatient so-and-so   :-)

[Elecraft] KPA100/KAT100

[Elliott Lawrence]

I have just completed successfully installing the amplifier and tuner in an EC2 
and interfacing it with the K2 and KIO2 data interface.  No difficulties were 
encountered and the alignment went exactly as described in the assembly manuals 
and the information from KK7P.  The one question I had regarding an interface 
voltage check turned out to be normal because the interface between the KAT100 
and KIO2 has a 1/2 voltage divider created by the series resistor in the KIO2 
and the base-emitter resistor in the KAT100.  I completed all of the alignment 
steps for the KPA100 with the K2 and then installed it in the EC2.

Great project, getting excellent keying reports and now I'm putting in the 
hours of operation needed to do the recommended retightening of the power 
transistor mounting hardware!

[Elecraft] KPA100 with KAT100 in EC enclosure

[Elliott Lawrence]

I have completed the initial construction of the KPA100 and performed the 
initial tests using the ribbon cable interface.  All of the resistance checks 
are within tolerance. All of the voltage measurements are within spec except 
for U1 pin 27 at 3.92 instead of 5.8.  The value of RP1 is 3.9k so it appears 
that the 8R line is 3.92v.  It isn't obvious that anything is dragging the line 
down.  All of the interface checks with the K2 are correct.

Any thoughts on a possible problem or is this within acceptable limits?

[Elecraft] KPA100/KAT100

[Elliott Lawrence]

I've read  several articles on combining the 2 units into an outboard 
enclosure.  Does anyone have an order list for all of the pieces that need to 
be purchased from Elecraft to accomplish the job? Don't believe a separate 
serial interface is required?

Thanks,

Thanks for all of the input on the project.  If Elecraft has all of the
necessary pieces at the Visalia DX Convention this weekend I will probably
take the leap and buy them!!

[Elecraft] K2 Power Control

[Elliott Lawrence]

I finally finished my K2 and installed the various accessory pieces.  I had two 
problems both solved with the reapplication of a soldering iron!!!  It's a 
great little radio and I enjoy breaking DX pile ups and rag chewing at the 5 
watt level.

I have a question regarding the power control. I can adjust the power in 0.1 w 
increments per the manual.  However for example, if I set the level at 5.0w the 
resultant output is usually higher. Sometimes by almost a watt. Other times it 
will be a little lower.  I am using the ATU that is calibrated properly.  From 
band to band the same power isn't always the same with no adjustmnet to 
control.  Wonder if RF is getting in the ATU control circuitry or the feedback 
path from the RF board?

Otherwise the radio is a joy to operate.

Happy New Year to all,

Elliott WA6TLA

[Elecraft] K2 #4424 Complete

[Elliott Lawrence]

My K2 #4424 completed today after several months of off and on building.  A few 
part issues speedily resolved by superb Elecraft service and several cockpit 
errors fixed along the way.  Unit met every tuneup without a hitch the first 
time.  Only slight issue is approximately 8.5 watts output on 12/10 meters.  T1 
thru T4 wound and placed exactly as instructions require.  All other bands in 
spec.  Will try a beefer power supply to see if that might be limiting the 
power out.

Now on to the accessories.
