[Elecraft] Elecraft CW Net Announcement

[kev...@coho.net]

Good Evening,

Propagation is slowly improving as the sun moves back north. The 
sun has stopped its recent blank spell and speckled up a bit. Between 
the effects of the solar wind and the change in season a few DX stations 
have been popping up out of the noise.  Work them for a while and they 
fade away.  I don't expect to catch a fish with every cast; I'd get no 
chance to think.


Speaking of meditating the snow has melted to where I can check 
more of my timber.  I took a long walk today through the youngest 
areas.  The alder took the hardest beating with Doug fir coming in 
second.  I found only one broken hemlock which got crushed by its 
neighboring alder trees.  The cedar all seem to have been spared.  I 
have a lot of cutting to do before I see the forest floor again.  If it 
weren't so much fun I'd think it was work :)


Please join us tomorrow on:

   14050 kHz at 2300z Sunday (3 PM PST Sunday)
 7045 kHz at 0200z Monday (6 PM PST Sunday)

73,
Kevin. KD5ONS

Re: [Elecraft] Random wire lengths for antennas

[Wayne Burdick]

Generally something in excess of 50' for both wires will provide adequate on 80 
meters and up.

[Elecraft] K3 Sensitivity

[jay Miller]

I assembled my K3/100 with the second receiver in December of 2010.  The
weak signal performance was much better than my original IC-756 rig. I did
not install the automatic antenna tuner.  I have continued to download the
software changes since then. 

 

Two years ago I installed the general coverage receiver modification.  I
thought it was my imagination at the time but I thought had experienced a
slight decrease in the primary and secondary receiver sensitivity.

 

Today I put my Kenwood TS-480 that I had been using as a mobile in the
shack.  I was listing to a couple of weak strength SSB QSOs using the K3.
Out of curiosity I switched over to the TS-480 and was surprised that the
weak signals were more "copy-able" on the inexpensive Kenwood than on the
K3.  Does this indicate a problem with the RX in the K3 or is the apparent
difference in the TS-480 RF gain come at the price of the definitely poorer
adjacent signal rejection?

Re: [Elecraft] K3 - stuck at MCU LD we upgrading software

[Don Wilhelm]

Jimmy,

You should see little voltage sag on transmit, especially at QRP levels.

Compare the voltage directly at your power supply terminals between 
receive and transmit.  If it stays up, then check your power cable to 
the K3 for adequate size wire and good connections.  If you have a DC 
power distribution device like the RigRunner, remove the K3 from it and 
connect direct from the power supply to the K3.


OTOH, if the voltage at the terminals droops during transmit, open the 
power supply cover and remove the bolt terminals - clean the solder lugs 
on the inside and the bolts, then reassemble making certain the bolts 
are tight.  If those bolts turn even a little bit when tightening the 
external bolts, they are not tight.  You must have tight connections at 
the power supply.

did reduce severely under any load, even QRP. That’s a strange quirk in the 
equipment but I think that’s it.

Subject: Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

Thank you to the three people that responded to this so far but each of you
accused me of having my friend run three tuners in a row. The KX3 turns it's
tuner off when it senses the KXPA100 is connected and turned on. There is a
setting in the MENU to turn off the tuner in the KXPA100 which we did and
have to keep watching as the equipment keeps wanting to turn it back on. The
problem we are having is tuning the KAT500. Hi SWRs are sent back to the
KXPA100 and it trips out. I was hoping there is someone out there that is
making this work. I have a K3S myself and a KAT500 and they work perfectly
together at 25 watts for tuning than the full 500 watts after it is tuned.
My friend does not have a K3S so we need to make the KX3 and KXPA100 work.

Thank you

Hi to the group

I have a friend with the following equipment.
KX3 with built in tuner.
KXPA100 with built in tuner.
KPA500
KAT500
50 ft of LMR400 coax
R9 vertical.
The KPA500 is not in the circuit at this time.
We try to tune the KPA500 using the station set for 20 watts and a hand
key.

The KXPA100 often kicks out. The SWR of the KAT500 changes quite a bit
over a tuning cycle and I think that is what is causing the trouble.


Is anyone else using this combination of equipment and can give us some
guide lines on setting up each piece of equipment and a procedure to tune up
the KAT500 without hurting the KXPA100?


Thanks to anyone that can help as this has turned into an expensive
problem that has destroyed three pieces of equipment.

Re: [Elecraft] Just bought a K3/10. What upgrades should I get?

[Don Wilhelm]

Andy,

Congratulations on your purchase.

As far as options go, first look at your antenna - if you have all 
resonant antennas, you do not need the tuner, but if you use a tuner, 
get the KAT3A - or if you plan on the KPA500 later, get the KAT500 instead.


Next consider your operating desires.  If you will be doing SWLING, get 
the KBPF3.  If you want coverage down to 100kHz, you will need both the 
KBPF3 and the new synthesizer.  There is also a capacitor that should be 
added when upgrading to the new synthesizer for coverage down to 100kHz.


If you do DXing, where you are operating split often, get the 
subreceiver.  If you order the subRX, a new synthesizer comes with it, 
so you will need to upgrade the synthesizer in your K3.


Doing voice operation, especially contests?  You may want the DVR option.

As far as filters go, operate with the filters you have until you can 
decide if additional roofing filters are wanted.  Remember that these 
are roofing filters and not the final filters - the DSP in the K3 
provides the final filtering, and its bandwidth has nothing to do with 
the roofing filters.
If you have the subRX and want to do much diversity receive, you should 
match the filters in the SubRX and the mainRX for best results.


Remember that you do not have to add everything at once.  Operate it for 
a while to decide if you want the capability afforded by the added options.

Re: [Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

[Kenneth Christiansen]

Hi to the group.

I promised to let you folks know what I came up with on my friends KX3, 
KXPA100, and the R9 vertical.

He got the KX3, KXPA100, and KPA500 back from Elecraft all repaired.

I put the station together and this time set all 120 frequency-SWR memories at 
the 20 watt level. They all set up OK and at that point we went to lunch 
feeling good that all the problems were gone.

We came back and started using the KPA500 on various frequencies. Any frequency 
we tried from 20 meters to 6 meters worked just fine at the 500 watt level.

On 40 meters any power over 400 watts would give a fault on every piece of 
equipment (KAT500, KPA500, KXPA100 and an ANT ERR on the KX3.

On 80 meters the faults would come on at anything over 300 watts. 

I felt the faults were quite violent so that more than likely explains how all 
three pieces of equipment got destroyed.

I studied the R9 which I put together last fall. On 17 meters through 6 meters 
there are stubs for each band and no loading coils involved. On 20 meters there 
is a trap so again no loading coils. On 40 meters there is a trap and a loading 
coil and on 80 meters there is another trap and loading coil. 

I noticed on 40 and 80 I could get them to tune to low SWR with the KAT500 but 
if I started sending my call the KPA500 would start showing more power and soon 
go into the violent fault.

Years ago I had a hustler vertical that would change the matched frequency as 
the coil heated up and I think this R9 is doing the same thing. Our solution is 
to run no more than 400 watts on 40 meters and no more than 300 watts on 80 
meters.

The specs for the R9 say it can handle 1500 watts and I suspect it can on the 
higher bands but at least this antenna can not on 40 or 80 meters.

I came home and tried my camping KX3 and KXPA100 with my KAT500 and Hy-Gain 
HY-Tower vertical and it seems to work well in any of the memory position which 
I earlier set with my K3S and KPA500 so I feel we have isolated the problem to 
the R9 my friend is using.

If anyone is able to use an R9 at higher power on 80 or 40 please get back to 
me and let me know how you are doing it.

To everyone else thank you for the band width and suggestions.

I consider this closed.

Re: [Elecraft] Just bought a K3/10. What upgrades should I get?

[Brian Hunt]

Oops. Sorry for the fat-finger spurious emission. 

Congrats on your acquisition!  My K3/100 is going on 7 years old and is about 
500 units newer than yours. I have only the 400 Hz filter and it's all I seem 
to need. Like you I'm 95% CW op with some contesting and DX chasing. 

Some folks like the internal ATU but I don't have it since I use a resonant 
antenna or a remote ATU. 

I think the new synth improves weak signal receive. 

The biggest add I've done is the P3 and it has revolutionized the way I 
operate. It's hard to beat a picture of what's happening around you on the 
band. 

Good luck. I know you'll love the K3.

Re: [Elecraft] Random wire lengths for antennas

[murphy]

True enough, so I initially used about 25 feet (actually 29 feet) but it failed 
on 60 and 80 meters.  I wanted to work all the covered bands.  So my 
recommendation is to use 58, 29 feet to cover them all.  Maybe something 
shorter will also work, but I will let others cut more wire first

Re: [Elecraft] Just bought a K3/10. What upgrades should I get?

[Bill Frantz]

Andy, congratulations on your new radio. I would operate it as 
you receive it for a while while deciding what upgrades you 
might need.


The 400 Hz filter is popular for CW, so I would see if it is 
satisfactory for your operating needs. The 100W upgrade is easy 
to install, but do you need an internal tuner? The new synth is 
a definite improvement, but if you aren't working in crowded 
conditions (DX pileups or contests), the old one is not bad.


If you are thinking about some particular upgrade, ask here and 
you will get a lot of advice, sometimes contradictory.

Re: [Elecraft] K3 - stuck at MCU LD we upgrading software

[Clay Autery]

I'm new to Elecraft (1 year), but with almost 30 years in IS/IT...

I always do the best I can to minimize potential problems when flashing
firmware.

This includes using a laptop or computer running with a truly
uninterruptible power supply.  A fresh COLD reboot of the computer and
radio for EACH flash.

Oh, and as suggested in the manual and/or the Cady book...

BACK UP YOUR FIRMWARE and SETTINGS!!

I save mine every time I make a change.  Storage space is cheaper than
keeping a log of changes between downloads.

I would be concerned about any significant (> .5V or so) voltage 
sag, particularly if operating at QRP power levels. It indicates 
that there is a high resistance in the power supply or the 
associated wiring, connectors etc.

[Elecraft] KXAT2: Recommended Random Wire Lengths

[murphy]

I love my new KX2 and the installed auto-tuner.  The manual mentions a
random wire antenna with a counterpoise and recommends #26 “Silky” from
The Wireman (catalog #534).  After obtaining 100 feet the first question
is how long?  Obviously I want it to tune 1:1 SWR, 80 to 10 meters but a
quick search of the archives and manual came up dry for specific random
wire lengths.  So I cut 29 feet x 2 and boom - no joy.  The 5MHz band
got no better than 4:1 SWR and 80 meters was, well, hopeless.  The rest
was good.  Ok searching the net the best I could find was
http://www.hamuniverse.com/randomwireantennalengths.html with the magic
number lengths: *29  35.5  41  58  71  84  107  119  148  203  347  407 
423*.  Still, no guarantee which would meet requirements on the
KX2/KXAT2.  So, after a splice and another cut, I can now officially
announce that a 58 foot "random" wire with a 29 foot counterpoise will
give a 1:1 SWR on all bands 80-10 on the KX2 using the KXAT2. :-)

Heavier gauge wire and a shorter run helps to reduce voltage sag.

Tony,

I used to have this problem all the time. It was maddening. I never knew if the 
rig was going to turn on. It was always necessary to restart my computer to get 
my K3/100 to talk to the app that resets the firmware. I had several 
suggestions to fix the problem. The one that proved most helpful was to get a 
different power supply. I was using a big Astron supply feeding into a Johnson 
power strip. Several devices ran off the power supply. It should have been able 
to supply plenty of power for everything because the other devices were low 
wattage users like a keyer. Anyway, I had a smaller Anstron device that was 
once used with a 2-Meter radio. It was fully capable of 100 watts. I hooked it 
up and the rig as a dedicated supply and it has worked perfectly ever since. 
You may have a different problem than me but that’s my story.

Tony,

I used to have this problem all the time. It was maddening. I never knew if the 
rig was going to turn on. It was always necessary to restart my computer to get 
my K3/100 to talk to the app that resets the firmware. I had several 
suggestions to fix the problem. The one that proved most helpful was to get a 
different power supply. I was using a big Astron supply feeding into a Johnson 
power strip. Several devices ran off the power supply. It should have been able 
to supply plenty of power for everything because the other devices were low 
wattage users like a keyer. Anyway, I had a smaller Anstron device that was 
once used with a 2-Meter radio. It was fully capable of 100 watts. I hooked it 
up and the rig as a dedicated supply and it has worked perfectly ever since. 
You may have a different problem than me but that’s my story.

Re: [Elecraft] K3 - stuck at MCU LD we upgrading software

[Lyle Johnson]

You may need to use the RS232 adapter cable in this case.

Lyle KK7P

Tony,

The usual reason for that is a glitch in the computer.  The fact that 
the USB port is no longer detected points more to the computer than 
the K3.


Re-boot the computer, and see if it detects the USB adapter - that has 
to happen first.  Even if the USB port is internal to a K3S, the same 
thing applies, you must get the computer to recognize the USB adapter 
and assign a COM port to it.  If the port is internal to the K3S, 
power cycling may help as well.


Then follow the instructions to "Force a firmware load" in either the 
manual or in the K3 Utility Help file.

Re: [Elecraft] K3 - stuck at MCU LD we upgrading software

[N2TK, Tony]

Hi Don,
Tnx for the advice. Rebooted the K3 and the PC. But what I had to do
additionally was hit "Close Port" on the K3 Utility. Then hit "Test
Communications". That set things straight for me to load the firmware. Not
sure why that problem happened in the middle of an upload. But all is fine
again.

[Elecraft] Beware of the speaker magnet on the KX2

[Steve Wilson via Elecraft]

The other day I turned on my newly acquired KX2 (thanks Santa!) and found that 
the audio had a horrible buzzing noise. I started to assume the worst, but I 
didn't have time to troubleshoot it.
This morning, I turned on the rig and observed the buzzing again. I turned the 
rig over and started to laugh! A used staple was caught in the speaker grill. 
Once I removed the staple, the audio was perfect. This incident reminded me of 
my old BlackBerry. One day a paper clip was stuck to it. I had no idea how 
magnetic it was!
Bottom line...be careful of any loose, metal objects that may be under your 
KX2! :-)

The only Re-Work eliminator I found helpful was the Mic connector.  This
made changing a mic easier, but you had to remove the side panel.  I concur
with Don's points on the rest.  Only good if you wanted to remove add-ons or
prep for future. If you build the radio with all the intended parts, then
just go for it and skip all the headers.  Great radio, a superior kit in so
many, many ways. And a labor of fun and love.

Harry and all,

I included the electrical information in the post below, but I failed to
mention the standoffs.  If you want to include the full "homebrew Rework
Eliminators", you will have to add the standoffs for each option.  Refer to
the Elecraft manuals for each option and order the required standoffs and
mounting hardware if you want to do a complete job.

If you do not want to remove the K2 heatsink when adding options, you should
order the 2 pin header for P6 (KAT2 manual or KPA100 manual), the standoff
for the K160RX and the standoff for the K60XV.  Those are the ones that are
covered by the K2 heatsink.  The other standoffs can be easily added without
removing the heatsink - just remove the bottom cover.

73,
Don W3FPR
---
Harry,

If you are ordering the options you want to include with the K2, there 
is little need for the Rework Eliminators.  There is very little rework 
when adding options - the "Rework" consists mainly of removing the 
jumpers that are normally installed when building up the basic CW K2 and 
removing/changing at most one capacitor for each option (the KNB2 
requires 3 resistors to be changed).  A careful perusal of the 
installation procedure in the manuals for the options that you wish to 
add.  The headers required come with the options that you purchase 
initially.

For those options that you may want to add later, it is a simple matter 
to install the female headers on the RF board and Control Board and use 
wire jumpers, and perhaps a capacitor or two in place of the actual 
rework eliminators.  Download and identify the headers required.

The most complex part of the rework eliminators is the KNB2 and the 
K60XV.  I do not recommend making the board changes (C71 value and 
D19/D20 addition) until you actually have the K60XV option ready to 
install.  The "Rework Eliminator" boards that you need are easily 
fabricated on perfboard and strips of male pins.

For the K160RX, you need only the header and a bent component lead for a 
jumper - stick the jumper wire in the header and do not install W1.
For the KAF2, you need only the 3 pin and 5 pin female headers mounted 
on the Control Board - do not install the wires for R18 and R19, but 
stick jumper wires made from component leads into the headers.
For the KNB2, you will need the perfboard and 8 pin male header - on the 
RF board install a 2.7k resistor at R88 and a wire at the R89 location. 
Your plug-in "eliminator" needs 3 resistors - a 470 ohm, a 100 ohm and a 
680 ohm.  The 470 ohm resistor goes between pins 1 and 5, the 100 ohm 
resistor goes between pins 1 and 6, and the 680 ohm resistor between 
pins 6 and 5.
For the KSB2, you need to install 3 pin headers at J9 and J10 and a 12 
pin header at J11.  bend 2 wire jumpers to plug into J9 and J10 - from 
pin 1 to pin 3 (do not install W2 and W3) and on a 12 pin male header 
strip on perfboard solder a .001uF capacitor between pins 7 and 12 - do 
not install C167.

That takes care of all the "homebrew Rework eliminators" except the 
K60XV option.  Since I do not recommend installing that until the K60XV 
option is built and ready to install, I have left that off the list. The 
VFO and PLL R30 voltages change with the addition of the K60XV changes 
and cannot be properly tested until the K60XV option is actually 
installed.  If you want to do a partial install of the K60XV, put a 3 
pin female header at J15 and put the leads of the 4.7pF capacitor into 
pins 1 and 3 of that header rather than soldering it to the RF board. 
You can also install the 8 pin female header at J13 and put a wire 
jumper between pins 3 and 5 (leave out W6 jumper).  BUT change the value 
of C71 and add D19/D20 as well as the coax cable only after you have the 
K60XV option built - that is only one capacitor to change.

If you want to install the headers at P3 and P6, you can do that at any 
time - no jumpers are required - one header

Shouldn't the only tuner being used in this configuration be the KAT500? You 
should have any tuner in the KX3 and KXPA100 in BYPASS mode, not MANUAL.

I have this setup.  It works well.  I would suggest a menu change to 5 watt
tuning with the KX3.  Do not tune everything at once.  Big error.  Do you
have a tuner in the KXPA100?  If so set on "Man" then tune the KX3 into the
KAT500.  This will stop what you are seeing.  Too many tuners going at once
will cause what you are seeing.  If that doesn't work, turn off the KX3
tuner and use only the Kat500.  Once tuned the rest should work.

Thank you to the three people that responded to this so far but each of you
accused me of having my friend run three tuners in a row. The KX3 turns it's
tuner off when it senses the KXPA100 is connected and turned on. There is a
setting in the MENU to turn off the tuner in the KXPA100 which we did and
have to keep watching as the equipment keeps wanting to turn it back on. The
problem we are having is tuning the KAT500. Hi SWRs are sent back to the
KXPA100 and it trips out. I was hoping there is someone out there that is
making this work. I have a K3S myself and a KAT500 and they work perfectly
together at 25 watts for tuning than the full 500 watts after it is tuned.
My friend does not have a K3S so we need to make the KX3 and KXPA100 work.

Thank you

Hi to the group

I have a friend with the following equipment.
KX3 with built in tuner.
KXPA100 with built in tuner.
KPA500
KAT500
50 ft of LMR400 coax
R9 vertical.
The KPA500 is not in the circuit at this time.
We try to tune the KPA500 using the station set for 20 watts and a hand
key.
The KXPA100 often kicks out. The SWR of the KAT500 changes quite a bit
over a tuning cycle and I think that is what is causing the trouble.

Is anyone else using this combination of equipment and can give us some
guide lines on setting up each piece of equipment and a procedure to tune up
the KAT500 without hurting the KXPA100?

Thanks to anyone that can help as this has turned into an expensive
problem that has destroyed three pieces of equipment.

[Elecraft] K-POD Issue solved

[Tony G6GLP]

Hi Guys,

You may remember I reported an issue with the K-Pod missing key presses 
etc. Since it was intermittent you can never be sure you have fixed the 
problem. Last night I was having a little play in the 160m contest and 
the k-pod started to play up almost 50% of the time so I had to do 
something. I picked a snap on toroid out of the misc box I have on the 
desk and clipped it on. I have no idea of the value type or anything 
else but magically the problem stopped. So it is/was RF getting in down 
the k-pod to K3 connecting lead. I am using the factory supplied lead 
and since it is quite short and nothing to do with the fact I couldnt 
fit more than one turn through the toroid  if I wanted to the toroid is 
just one turn clipped over the connecting cable.



While I shouldnt say its cured I can say my problems went away for the 
rest of the contest that I took part in. Time will tell if the problem 
on other bands have gone as well or I may require another toroid.
