[Elecraft] KX2 mobile operation in Iceland

[John Harper]

Thanks to those who called - the radio performed well, allowing me to work
3 continents from various parks in Iceland. The portability-to-features
ratio of the KX2 can't be beat.

Here is a video of it in action from the cramped quarters of a tiny rental
car with a roof-mounted vertical. All activity was on 15, 17 and 20 meter
CW.

Some drone video precedes the radio portion:

Re: [Elecraft] KX2 question

[Rick Bates, nk7i]

For such documents that I (might) need when not at the computer, I use 
Dropbox.  That way it's in several places at once, including on my phone 
(which is always with me).


It's free, up to small storage limits, adequate for that task. If I need 
to share something, I send the link (which if a large file, doesn't clog 
my LAN, once it's in the cloud).

That was indeed the document I was mis-remembering as one page...

But it describes how to get INTO the CW announce mode, but does not 
tell how to EXIT the mode.


I think I did a device reset to go back to turn CW announce OFF.

I also note that I appear to need a newer version of the manual that 
came with the radio. I downloaded the e-version, but my computer does 
not fit in my day-pack!

[Elecraft] KX2 with KXIBC2, Firmware 3.02.

[Ken]

Hi all,
Installed the subject charging board yesterday.
Page 5 in the manual says "Tap DISP and rotate vfo B until you find the "VBAT" 
display.
All I can find is BT and PS. No VBAT?

KXIO2 = Not INST. 
KXIBC2 = NOR.
BT = 11.9V now
PS = 14.1V now
LED is on.
Thanks, Ken, W2GIW

[Elecraft] KX2 Shack-In-A-Box w/ Extras

[Joel Black]

My outdoor activities (cycling, MTBing, and astrophotography) don’t leave any 
room for outdoor amateur radio so I am relegating that hobby to my home. 
Therefore, I have decided to sell my KX2 Shack-In-a-Box with extras. I am the 
second owner of this fantastic piece of technology. In my days as a radio 
operator in the Marines, I'd have killed for a radio with these capabilities in 
this lightweight package instead of a PRC-104.

At this time (and until I change my mind), this is being sold complete. Please 
do not ask at this time for me to part it out. If I cannot sell this as 
complete, *then* I will decide to part it out. I will not consider requests to 
part it out until *I* have decided to part it out. Please do me the favor and 
do not ask for me to part it out until that time.
 
KX2 Shack-In-a-Box includes:
KX2 80 - 10 m SSB/CW/DATA transceiver
KXAT2 auto tuner
KXIBC2 internal battery charger (installed at the factory)
KXIO2 RTC (original in the KX2)
KXBT2 Li-Ion battery pack
KXBC2 external battery charger
KX2GNDPLUG quick release ground plug
MH3 hand mic
ES60 carrying case
KX2 book by Fred Cady
Sorry, no hat. I didn’t get one when I purchased from the original owner.
 
Extras:
AX1
AXE1
KXPD2
N0SA SOTA paddle
BaMaTech straight key
SideKX Heatsink end panels and cover
SidKX KX2 tall leg
SideKX KXPD port cover
PAE-Kx33 PS
DigiRig Mobile
DigiRig USB Isolator
DigiRig KXx Coiled cords
Bioenno 12V, 3Ah LiFePo battery
Bioenno 2A charger

There may be more. If so, consider it a lagniappe.

Price is $2000 for all shipped to your door. I will accept a cashier's check 
drawn from a US bank / credit union, a USPS money order, a Zelle transaction 
(will have to split), or payment to my wife's Venmo account.

Pictures available upon request.

Regards,
Joel - W4JBB

P.S. I forgot to mention, this radio just came back from Elecraft who replaced 
all the encoder knobs and installed the KXIBC2.

[Elecraft] KX2 Utility Version 1.23.5.22

[Mike Morrow]

I notice that on 7 June 2023 the corrected version 1.23.5.22 of the KX2 Utility 
has been released.
It restores the ability to set time and edit message memory.
I have missed all talk of this version on either KX2 list, if this has been 
mentioned earlier.

[Elecraft] Kx2 and IQ

[Hajo Dezelski via Elecraft]

Hello,
 
knowing that the chances for a new board with an IQ - Output for the Kx2 are 
minimal, I would kindly ask again, whether there is a chance for this connector.
 
Background for this question are new developments, which would significantly 
improve the possibilities of the Kx2. I am thinking about the Quantum SDR 
https://quantumsdr.com/about
 
Or are there other solutions to put some sort of panadapter to the Kx2?

Re: [Elecraft] KX2 Mic

[Lee Hiers]

I know Morse.  I operate CW 95% of the time.

My order is for a long-promised and non-delivery-updated power amp for a
K3/10.  And before you come up with some BS about "now's a good time to try
QRP", I've operated 11 of the last 12 years at 5W or less.

The fact is, Elecraft's poor communications on all these delays is
inexcusable.

I've been an Elecraft fan and supporter ever since I purchased my first
Elecraft rig over 10 years ago, and recommended them to many for their
superior products and excellent customer service.  That is over.

You people who are calling us whiners because of the poor customer service
we have received from Elecraft are doing the company a huge disservice, as
you're just pouring salt in the wound with snide comments.

Re: [Elecraft] KX2 Mic

When I ordered my KX3, the mic was optional and I didn't order it.

If you think this topic is about microphones, you're not paying attention.

Re: [Elecraft] KX2 Mic

[turnbull]

Friends,    Why bring up the CW v SSB canard.   There is a supply issue.     I 
too prefer Wayne to stick to engineering new features and work arounds.    It 
is good that on iccassion he lets us know what he is doing.   Wayne and Eric 
are active hams.    A complaint was warranted but Elecraft is a small first 
class company in a struggle.    They are not alone.          Peace my good 
friends - your points are well made.    Elecraft is under pressure and I just 
pray her principals do not retire at the normal age.     As much as I 
appreciate the market, please do not go the Drake or TenTec route.   So many 
fine marks are but a memory.     73 Doug EI2CNSent from my Galaxy

A small field-test run is being built as we speak. Over the past several months 
I collected names of volunteer field testers (you know who you are :)

I can fully agree and confirm this! My daughter studies in Tel Aviv and
everytime I am going to visit here, I take my KX2 with me. Even with El
Al there is no issue at all to take it on board as carry on.

The ONLY issue I have... my backpack used as carry-on contains the KX2,
a X230 Laptop, a Kindle and my D300 (incl. 16-85mm lens)... this needs
to be unpacked before and packed again after the x-ray machine... and it
is quite heavy ;-)

Re: [Elecraft] KX2 on commercial airplane

[Mark Goldberg]

I've been a member of aviation standards committees, and the quality of the
members is similar. The best engineers from multiple companies come
together, along with hundreds of years of combined experience. The battery
standards committee was across the hall from ours one time. Theirs was much
more heated. These standards are indeed there for a reason, and based on
real world experience. People from the NTSB, Transport Canada, and similar
agencies also attend. They have investigated many accidents and want to
make sure what went wrong and killed people does not happen again. They, in
my experience, are some of the sharpest people I have met and worked with.
I had long talks with the folks that investigated Swissair 111. That is one
reason I am so careful with electrical installations, at home and even in
our RV, which has 400 Ah of LifePO4s under where we sleep.

I believe that about a 20 Ah LiFePO4 is about the largest that can be put
in your carryon. I have several smaller ones.

One advantage to having batteries in your carryon is that you will not be
selected to put the carryon in the luggage compartment if the overheads are
full. Tell them there are lithium batteries in there and they will select
other luggage.

[Elecraft] KX2 on commercial airplane

[John Harper]

I plan to take a 3AH (36WH) LiFePO4 battery on an international flight (to
HC5) in a few weeks. To conform with the FAA's regs (link below), I'll have
the Anderson power-pole end & the charging jack sealed with tape. Seems
simple enough - I'll post here if there are any problems.

All of your post is well said, Jan. We have the right to our opinion, 
but we don't have the right to endanger others by acting out on the 
basis of our ignorance.


For nearly 40  I've been a member of the Standards Committee of the 
Audio Engineering Society, and lead author our Standards on EMC. I can 
report that all of our Standards are based on Applied Science, and the 
result of serious engineers who are practitioners in a broad range of 
pro audio -- broadcast, recording, live sound -- all with a solid 
engineering grounding. Those lacking that background, or with "an 
agenda," or to be unwilling to yield to others who know more about an 
issue, are quickly sent to the back benches. And all of us have an 
excellent BS filter. The goal is simple -- write Standards that make 
systems WORK, in the REAL WORLD.


One of the things that design professionals from different engineering 
disciplines do in design meetings is play "what if" scenarios to 
evaluate design decisions. A prime example in the real world I've often 
cited is, the design team of the Fukushima nuclear reactor failing to 
ask, or failing to have the imagination or education to come up with 
possible answers to the question, "What Could Possibly Go Wrong With 
Putting Emergency Power Generators in the basement?" In 2011, Mother 
Nature answered rather emphatically that question that should have been 
asked or satisfactorily resolved, but wasn't.  Note that this is an

Re: [Elecraft] KX2 on commercial airplane

[Geert Jan de Groot]

I tried telling the TSA guy a little box of electronics and such was for my 
hearing aid.
He thought I was spoofing him and called his supervisor when he asked if it 
received Fox News, and I said not in my house. I explained it was the Bluetooth 
gear for broadcasting TV audio into the earpiece. A little demo for the TSA 
folks was cordial but I almost missed the flight.
One step for man, a giant step for mankind.


There are restrictions on LiPo batteries for a reason. Restrictions on 
maximal capacity of the battery and how the battery is packed - inside a 
radio OK, loose not OK.


I am pretty sure the KX2 with built-in cells is OK since these can be 
sent unrestricted in mail. The Bienno may or may not be - bigger 
capacity, loose battery, and the cells are only protected by plastic 
foil. If the cells get crushed in your carry bag, what happens?


If you've ever had a LiPo go rogue on you you will understand why TSA 
has issue with the possibility of LiPo incidents inside a metal tube you 
cannot step out of.


We as hams may "know it better" but the fact of the matter is that the 
TSA rules are there to keep flights safe. Trying to play them by telling 
them a lie is dishonest, dangerous and perhaps even illegal. *If* you 
know better, you should assist TSA in managing the risk, not lie to 
them, even if that means that you cannot carry the battery you want to 
carry.


I've carried some pretty interesting stuff over the years and always did 
so fully open. It has raised issues, there has been cases where a 
manager needed to get involved, but on a proper trip this was all 
prepared in advance (by asking the airline, not a mailing list) and 
everyone was happy with the approach and the preparation taken. I also 
found people to be pretty accommodating if asked correctly.


And if you feel otherwise and know it all better - it's a free world and 
everyone has an opinion! - then I kindly ask you to identify what flight 
you will be on so I will take the next flight, thank you.

[Elecraft] KX2: Command to tune VFO (a/b) up or down one notch using current Rate setting

[Mark Hatch]

Hi,



Tried the group.io Elecraft list, but no suggestions. I get that this list
tends to be for the larger elecraft products, but some of those commands
work on their smaller products too….




First attempt at sending commands down to my KX2 and need to be pointed to
the right command.

I am trying to have my KX2 tune up or down depending on the current setting
of the RATE command. Found the UP/DN commands, but they move the frequency
up or down depending on their parameters. I just want the amount of change
to be dependent on whether coarse rate is selected or not via the Rate
button. Which command does this?

And the bonus question...

If in OFS mode, will this command that targets VFOB move VFOA up/dn by the
coarse setting? The UP/DN commands when applied to VFOB just changes VFOB
frequency and seems to ignore whether OFS is on or off.

Thanks!

[Elecraft] KX2: Transmit Power 10m Band

[Reed Fite]

Hi Peter,
I was using a different laptop with a its own mail app & for some reason the 
text didn't show up.  I just sent Michael an email with the info he needed to 
get his KX2 to work on 10 meters.  
For those that have this problem with their KX2 not transmitting full output on 
10 meters just do the Automated Transmit Gain Calibration on page 39 of the 
manual.

[Elecraft] KX2: Transmit Power 10m Band

[Michael Urspringer]

Elecraft KX2:

If I set the transmit power to 10W on the 10m band, it seems that the
output power is 0W if I try to send. At least the RF power display does not
display anything. Same with 9.8W. If I set the value to 9.6W (or lower)
then everything is back to normal. This does only happen on 10m, all other
bands are fine with the 10W power setting. Is this a known bug or is
something wrong on my side?

Thanks,
Michael

Re: [Elecraft] KX2 WTB(uild) external amplified speaker

[Andrew Moore]

Hi all - thanks for the replies regarding speakers.

I do occasionally check the local thrift shop to see if there are any
electronics on the shelf to take apart for components, and they do
currently have a set of amplified PC speakers for short money. But I got
bit by the homebrewing bug recently so I want to build something from
salvaged components. I think I have everything on hand now to do that.

I mentioned this project to my son a few weeks ago - told him I bought some
cheap amplified speakers at Best Buy then returned them, unopened, because
it occurred to me I'm a ham so I should be able to build my own instead. He
says good idea, that way you'll appreciate them more every time you use
them.

How it took him 5 seconds to realize that, and 30+ years (as a ham) for me,
is beyond me ;)

Re: [Elecraft] KX2 WTB(uild) external amplified speaker

[Brian Hunt]

I found a pair of amplified speakers at a thrift shop that meet the need pretty 
well. Can’t beat the $6. :-)

[Elecraft] KX2 WTB(uild) external amplified speaker

[Andrew Moore]

KX2 arrived yesterday after a ~15 week wait, which was pretty much spot on
with Elecraft's original estimate.

One of the best features is, especially for a compact rig with limited
dedicated controls, the ability to assign a programmable function button to
an otherwise buried menu feature. For menu features that are binary choices
(such as enable/disable CW transmit), not only does the PFn button activate
the menu item, but it also toggles the parameter and dumps you right back
into operating mode. For example, you can toggle between "CW transmit" and
"CW practice (no transmit)" by pressing only two buttons. No need to go
through deep menus. Kudos to KX2 designers for thinking ahead.

One of the not so great features is the internal speaker. It's even raspier
and more distorted than the forward-facing one supplied with the KX3. This
is to be expected; there are design trade-offs and this rig wasn't designed
to be a desktop model with high wattage audio output.

My typical use case for the KX2 is to listen to it in the background on the
desktop with good quality speaker audio, and then to switch to
headphones/earphones when in QSO.

So I'd like to build an audio amplifier to convert the KX2 headphone output
levels to say 5 watt speaker output (one of the two channels will suffice)
for listening to relatively undistorted audio in the shack. A good starting
point is knowing what the output level and impedance is for the headphones
jack. I measured approx 20 mV P-P (impedance unknown) at an audio output
level around "AF 10" according to the KX2 display. Does this sound about
right?

Bonus points: First QSO with the KX2 was from Maine to Bermuda at 1 watt.

Thanks,
-Andrew NV1B

[Elecraft] Field Use of the Elecraft KX2

[Michael Parsons]

Hi all,

Just recently subscribed to the mailing list and wanted to drop a quick note. I 
got my Elecraft KX2 off of a ham from the Washington state area last summer and 
it has been an excellent addition to my operations. 

I’ve done 12 Summits On The Air activations and over 65 Parks On The Air 
activations in 10 different states since getting the KX2. I’ve used the AX1 
antenna and the AXE 40m extension as well as a PackTenna Mini 9:1 EFRW for most 
of them. 

I just started doing some antenna reviews for MFJ as well and have had both 
issues and successes with them all. 

I will include a link to my Ham Radio YouTube channel where I post all of those 
videos.

Thanks and 73, 

Mike (K0FYR)

[Elecraft] KX2 improvement: up to 2x more operating time at 10 W from internal battery

[Wayne Burdick]

Those who operate the KX2 at a full 10 W from its internal battery pack may 
have noticed that power automatically drops to 5 W after a certain amount of 
time.

A few months ago, Rich (AC7MA) pointed out that this was occurring when the 
battery still had 60-65% of charge remaining. So we definitely weren't getting 
as much 10 W operating time as we could. That extra 3 dB (1/2 S-unit) can be 
the difference between being heard -- or not. 

We have a new field-test firmware release that provides approximately twice as 
much operating time at 10 W. This was accomplished by changing the supply 
voltage required for 10 watts from 10.0 V down to 9.0 V. 

Note that this change only applies to CW mode. Voice and data modes still 
require 10 V minimum in order to ensure acceptable transmit IMD levels given 
the FET PA devices. But since a large percentage of SOTA and general field QRP 
activity is in CW mode, many users should benefit.

In lab tests, a KX2 with the new firmware transmitted a continuous CW message 
(no gaps) at 10 watts for 90 minutes before dropping to 5 W. It then ran for 
another 20 minutes at 5 W before shutting down. Calculations show this amounts 
to about 78% utilization of the internal battery at 10 W, then another 15% 
utilization at 5 W. This is a much better tradeoff. 

Actual transceive time at 10 W TX will of course vary with duty cycle. Typical 
CW SOTA operation has a very high duty cycle, as much as 50% transmit time. 
That 90 minutes would then translate to some 180 minutes (3 hours) of 
rapid-fire SOTA CW time at 10 W on a single battery charge. Other QRP activity, 
such as hunt-and-pounce contesting or rag-chewing, often has a much lower duty 
cycle -- averaging perhaps 10-20% transmit time. That would mean some 6 to 12 
hours of operation at 10 W.

If you're a CW op and you'd like to give the new firmware a try, please contact 
me directly. I'll send it to the first 20 or so requesters to make sure we give 
it a good shake-down before releasing it as beta.

Additional KX-line firmware updates are in progress and will be made available 
as time permits.

73,
Wayne
N6KR

[Elecraft] Kx2 or kx3 with ax1 and digirig ft8

[Tim Tucker]

Has anyone successfully used this combo? I bought the digirig to cut down
on cable mess when travelling. I can RX fine but on TX can't seem to get
output audio set to where it drives the rig properly without what seems to
be excessive RFI, even with the power level set low. The apparent RFI
causes garbled tx...i can hear it by pulling the speaker cable and
monitoring on the rig.  Any insights would be appreciated.

Re: [Elecraft] KX2 mic

Unfortunately Eric the Alex Mic has been discontinued for several years and 
there isn’t any new/old stock around only if one shows up on the used market. 
I’ve been looking and watching out for one for several years now and kicking 
myself for not buying one when they were first offered.

Re: [Elecraft] KX2 temperature

[Gary Slagel via Elecraft]

I have trouble with the KX2 keyer malfunctioning when I'm operating with the 
radio sitting outside in direct sunlight.  It happens after 20 or 30 minutes of 
steady contest style QSO's on SOTA activations.  I haven't spent any time 
troubleshooting other then trying to keep it shaded with whatever is handy to 
droop over it.  
I wonder if the Pro Audio Engineering Kx22 Heatsink kit would help with that 
issue?

Re: [Elecraft] KX2 temperature

I expect he meant “existed for the KX2/KX3”.

The Heathkit SB-230 is conduction-cooled with a beryllium oxide thermal link to 
conduct heat away from the anode to the heat sink.

Re: [Elecraft] KX2 temperature

[Gary Memory]

I guess I misspoke.  I have boxes and boxes of "heat sinks" that I've
collected thru the years.  I use them all the time.  I'm constantly looking
on eBay for a size or two, for a given project, almost on a monthly basis.

I had no idea that after-market heat sinks existed specifically for the
KX2.  And they look very nice as well!  But again, I've never thought to
look until I saw this thread.

My sincere apologies.

Gary, N7BRJ

Heat sinks have been widely used since the introduction of 
semi-conductors in the '50s. I don't know, but I suspect that they were 
used with high power tube gear. They are discussed in Chapter 4.11 of

Re: [Elecraft] KX2 temperature

[Gary Memory]

I had no idea heat sinks existed.  But, I've never looked, I suppose.
Looks like a good idea, but I'm guessing the radio will no longer fit in
its case.  I ordered a set of heat sinks to try 'em out.

My process to deal with the heat is perty much what Brian said.

Thanks for the thread!  I learn, I win.

Re: [Elecraft] KX2 temperature

[Brian Hunt]

I believe the trip temp. is 60c. The rate you get there, of course, depends a 
lot on power setting, mode and ambient temperature. I’ve found at normal shack 
ambient I can cycle FT8 pretty quickly at 7 watts. But I always monitor PA TEMP 
and back it down if necessary. At the beach with a 55f breeze - no problem  

It’s a great little rig. Have fun!

[Elecraft] KX2 temperature

[Bill Lederer]

Team:

I discovered that the KX2 will trip out if its temperature gets too high.
Clearly, this is a good thing. I am considering getting the heat sinks for
the side. I now run with the temperature displayed.

My question in relation to this is: is there a fixed temperature that it
will trip out at? Alternatively, what is a  good threshold to observe to
avoid over-temperature  operation? The manual does not seem to be very
specific.

Thanks for a great radio (I have it in my office  upstairs with a wire to a
tree, and get on the air between meetings.) and for a great forum.

Re: [Elecraft] KX2 not remembering Mic gain setting on ADATA

[Gareth M5KVK]

It appears the problem is more deep-seated.

I’m away /P right now and decided to do some FT8 using a Raspberry Pi. I set up 
the Tx drive (seemingly) OK, by pressing Tune on WSJT-X and adjusting Tx level 
and Mic gain to get the right amount of ALC.
However, when I then try to Tx again, TX LED lights but there is no drive. A 
Very slight nudge of the MIC gain causes 5-bars on the display, but next time I 
Tx it’s back to no drive.

Has anybody else experienced this?

Subject: Trouble using MH3 microphone with KX2

Hi all
I’ve typically been using my MH3 with a KX3 for /P operating from my campervan. 
This last week I’ve been doing some SOTA activations, so I’ve been using my KX2 
instead.

I noticed a couple of issues when setting the Mic gain.

I followed the advised procedure and reduced PWR=0, TX CMP=0, squeezed the PTT 
and spoke normally into the MH3. I found that there was no indication at all on 
the ALC meter until at about MIC=65, ALC jumped to 6-7. Mic bias is on.

I also noticed on a few occasions that when operating, pressing PTT had no 
effect until I slightly increased the MIC gain.

The MH3 works fine on my KX3, so I’m assuming the MH3 is OK, but I can’t figure 
where the problem lies.

Re: [Elecraft] KX2 to a handlebar mount

[Julia Tuttle]

(Mike sent me some pictures off-list; the cross-section of the bar is
roughly elliptical, maybe 2-3x taller than it is wide.)

It looks like a strap mount might work. I've got a cheap one for a speaker
on my bike, but if you're going the RAM route, something like this might
work:

Take a look at Lido Mounts (www.lidomounts.com ) 
that offers a bicycle mounting bracket that one can then attach various 
mounting points for different items such as HTs and front panels of various 
radios.  See if the panel they offer will for the KX3 will work with the KX2.  

I have a Segway I2 which has their mounting piece for a bicycle that I’ve 
attached their mount to hold a HT using the belt clip.  So the question is 
whether you can ‘mix and match’ to get what you need.  There is a mounting 
package for the KX3, but it includes hardware for mounting the assembly in a 
vehicle, not a bicycle.  You can call them at 949-690-5616 to discuss your 
needs.  They’re on the West Coast so take that into account when calling them 
if you’re not on the West Coast yourself.

Hope this helps,

Would the Side KX KX2-Mount

You can add i.e. any RAM Mount parts to fit it to whatever you want.

The specs give a current of 1 to 2 A at 10 W. That varies based on the supply 
voltage, so you need to pick a voltage to get a good answer for that.

Typically 1.2 to 1.5 amps, varying somewhat with supply voltage and load 
impedance.

 
> 2.  What is the narrowest receiver filter width on CW?

50 Hz primary audio filter, 30 Hz audio-peaking filter (APF). These can be 
controlled independently. The bandpass can be widened up to about 4 kHz, as 
well as shifted. The KX2 also has DSP-based noise blanking, auto-notch, and 
noise reduction.

Re: [Elecraft] KX2 Questions

[Bill Lederer]

I have the kx2 and absolutely love it.

1.  What is the approximate current draw for the KX2 on transmit at 5 watts
CW?2.

At 10 watts, it is 1.87 amps. At 5 watts, it is 1.49 amps. Receive is about
0.15 amps.



2. What is the narrowest receiver filter width on CW?

It goes down to 0.05 kHz.

Re: [Elecraft] KX2 Questions

[Bob Liesen]

Hi Dave,
  I don't have those numbers in front of me, but wanted to offer that I
have a KX2 and love it.  The learning curve for me was pretty steep in
terms of the menus etc, but YMMV.  I run almost exclusively CW, and find it
performs very well in that mode.   I would strongly recommend the book that
Elecraft offers for this rig, as it is much more detailed than the basic
user manual.

72 es stay well!

[Elecraft] KX2 Questions

[djchase]

I am a long time CW operator, but new to this group.  I am considering 
purchasing a KX2, but I have been unable to find answers to these two 
questions:1.  What is the approximate current draw for the KX2 on transmit at 5 
watts CW?2.  What is the narrowest receiver filter width on CW? Many thanks in 
advance for any help with these questions.73 es 72,DaveK8RXB Sent from my Galaxy

Re: [Elecraft] KX2/KX3 Heatsinks

[Julia Tuttle]

I have one of these and I love it -- I don't have to think twice about
running 15 W on FT8 or JS8Call.

(I also like their power supply -- I don't (yet) need the amperage the
SS-30DV can put out, it's a lot easier to drag to my girlfriend's house,
and it hasn't caused any RFI issues )

Re: [Elecraft] KX2 tx low power on 80M SSB

[Nate Jedinak]

Elecraft indicated this behavior pointed to a failure in the output block. 
Since Elecraft has mine now for repair of this issue, we will get a definitive 
answer as to whether this is firmware or hardware.

Great to hear, Dave!  

I’ll be posting the outcome of my KX2’s trip back to elecraft, so watch the 
reflector if you’re interested in following along.  As of now no ETA from 
elecraft, it’s been there about 2 weeks so far.

Re: [Elecraft] KX2 tx low power on 80M SSB

[Dave Jones]

Thank you to Nate W1NAT and Reed W4JZ for your quick responses to my post. I 
have carried out the TX gain calibration as you have both suggested and that has 
fixed the problem. I now have the correct power output on all bands from 80 
through to 12M. 10M is still a little low initially (about 4W) but the power 
comes up with brief CW carrier or just as I talk on SSB to 10W. I can live with 
that as I don't use 10M very often.


Thanks Dave VK4FD

[Elecraft] KX2 tx low power on 80M SSB

[Reed Fite]

Dave, try doing the Calibrate Transmit Gain that is in the Utility under 
Calibration. I had that exact problem in the 80 & 10 meter band. Tech at 
Elecraft told me to do this. That fixed the problem.  I had to do this several 
times & found it worked better on a old dummy load than it did on one I built 
from Elecraft.   The old one was not exactly 1:1 on the 80 & 10 meter band. 
Don't know why that made any difference, but it did.

Re: [Elecraft] KX2 tx low power on 80M SSB

[Nate Jedinak]

Dave,

I have that exact problem with my KX2 on 10m.  See my recent thread here: 
https://www.mail-archive.com/elecraft@mailman.qth.net/msg247537.html

Elecraft support said that situation is indicative of a failure in the output 
stage, and my KX2 is currently back at elecraft for repair. I sent it back in 
early March.  I will update my reflector thread with the outcome of the repair, 
so watch this list for details. 

I never use 80 on that radio, so I’m not sure if the issue existed there, 
unfortunately.

[Elecraft] KX2 tx low power on 80M SSB

[Dave Jones]

Hello all I wonder if anyone has come across this problem that I have with my 
KX2. After initial turn on or after changing bands to 80M the tx power output is 
2W if the power setting is 10W or above. If I keep talking into the mic (MH3) 
and pressing and releasing the PTT then the power will gradually increase to the 
correct level. If the power is set to any thing below 10W then the power output 
level is correct.


The CW power output on CW is not affected at all and if I enable the CW on SSB 
feature not only does that give the correct carrier power output but the SSB 
power level is also correct after a brief press on the key. Once this has been 
done the power output is correct until the radio is turned off and then back on 
or the band is changed to another band and then back to 80M.


80M is the only band affected, all other bands give the correct output. 
Hopefully someone is able to help me with this problem.


Thank you Dave VK4FD

Re: [Elecraft] KX2 Starts Off with Low Output on 10M

[Tim Tucker]

Mine does that too.  What works for me is to tweak the mic gain up and then
back to the same level and it starts working normally.  Seems to me like
there is a firmware bug with the radio that hasn't been figured out and
addressed yet.

Re: [Elecraft] KX2 Starts Off with Low Output on 10M

[Nate Jedinak]

Unfortunately, this did not fix my particular KX2.  TX Gain calibration was 
completed successfully, but the same issue persists.

I also did the TX bias calibration, and noted that bis on Q6 took ~45 seconds 
to complete, vs the 3-10 the manual suggested.  Q7 was fast.  Q6 wavered a lot 
between .3-.7v.  I suspect this suggests the problem is perhaps indeed 
hardware-related.

Thank you to everyone on the list who responded with ideas to check.  I’ll get 
this one packed up and sent back to Elecraft.

Re: [Elecraft] KX2 Starts Off with Low Output on 10M

[Brian Hunt]

Nate,
A couple more questions:

Does the KX2 do the same thing on CW?

Did Elecraft say anything about doing a TX gain calibration?  This can be done 
with the KX2 utility although I haven’t done it on mine, just on my K3. It sets 
the per-band gain coefficients  Be sure to save the current CONFIG file so you 
can restore it if needed. You will need a good dummy load an a stable power 
source. The procedure is on p. 38 of the Rev A5 Manual. 

Good luck,
73,
Brian, K0DTJ
