Re: [Elecraft] New wierd K3s behavior

[Michael Eberle]

Mine does this on 6 meters if SPLIT is enabled. Turning SPLIT off and 
then pressing TUNE it will put out power.  Turn SPLIT back on and TUNE 
will put out full power until the next power cycle of the radio.  
Strangely, it only happens on 6 meters.


I posted about it here before and was told it was probably an issue with 
WSJT-X which doesn't make sense because the radio behaves this way 
without WSJT-X even running on my computer.  I don't know how WSJT-X 
could change the K3 firmware.

When I turn on my K3s (and let it finish booting) and try pressing TUNE

A quick trip to CW then hitting a few dits on the paddle produces the
expected 100w barefoot power.

Then returning to DATA A and TUNE and the expected tune power is emitted.

No idea why this would occur and it is a new thing. I have recently updated
to the latest beta firmware for the enhanced KPA1500 integration. Perhaps a
bug was introduced there?

Ideas?

Is it interfaced to your K3 via the serial port?  The wiring

Re: [Elecraft] KPA1500 ATU

I'll try that, but I suspect the delay in switching the ATU will 
persist.  I'd like the option to turn off that delay, so the beginning 
of my call isn't cut off.

Re: [Elecraft] When to use the preamps on the KX2/KX3 vs. K3/K3S

[Edward R Cole]

Just to add a little info, I measured and compared my KX3-SN475 to my 
K3-SN4043:

http://www.kl7uw.com/HF.htm  Half-way down the page.

KX3 on 6m with preamp on was -127 dBm with 2.8-KHz SSB*
K3 on 6m with ARR Gasfet preamp was -137 dBm*
on 10m the K3+PRE outperformed the KX3, as well

Subsequent to this testing I acquired a PR6-10.  I helps the K3 
tremendously but not quite as much as using the ARR preamp**. 
Subjective impression is the PR6-10 equals the KX3 in MDS.

*Add 7.5 dB for MDS at 500-KHz bw
** Uses mgf-1302 GasFet with 0.5 dBNF and 25 dBG

I don't own a KX2

[Elecraft] KX3 station for sale

[David F. Reed]

I am putting my KX3 station up for sale; its seems that my KX2 has 
replaced it in the portable use, and I just move my k3 to the other 
shack when I go there...


The station is operating perfectly, no smoking environment, very clean 
appearance; it has the following items:


   *KX3**-F* (factory built) serial number 0620; has handle style side
   plates, external HD heat sink and associated accessories below: *
   *

   *KXAT3* internal antenna tuner *
   *

   *KX3-2M-AT *internal 2m module to fit with antenna tuner installed

   *KXFL3* Internal Dual-Passband Roofing Filter

   *KXBC3 *Internal NiMH Charger / Real-Time Clock

   *PX3-F *Panadapter for KX3; Assembled*
   *

   *KXPA100-F *100 W External Amplifier-Factory Assembled *
   *

   *KXAT100* Internal Auto Antenna Tuner*
   *

   *KXPACBL *KX2 and KX3 to KXPA100 Integrated Adapter Cable

You will see that if you add them up new (not counting the external heat 
sink and end plates), before shipping you come to $3,739.55.


I would like to get $2,500 for it, shipping and insurance prepaid, 
within the US; PayPal preferred.


Please email me direct for inquiries; I can provide photos for serious 
inquiries, and if requested will provide my phone number off list.


Thank you for the bandwidth.

[Elecraft] PX3 Screen Issue

[Joe Caldwell]

I assembled my PX3 kit over the weekend and the screen is not displaying
properly.

It's almost as if the contrast is set way too high (if that's possible).
>From head on almost nothing is visible (it just looks like a white screen),
but from certain oblique angles you can just make out the spectrum display
and read the menu entries, etc. I installed the latest firmware and played
around with the brightness, but there's obviously something wrong. Other
than the screen the unit appears to be functioning correctly. I was able to
pull a "screen capture" using the PX3 utility and it tracks my KX3
frequency as it should.

I was thinking the ribbon connection to the screen needs reseated, but
maybe it's just a bad display.

Has anyone ever had this issue before? I emailed support a couple days ago
but haven't gotten a response.


Thanks,

Joe, N3XE

Re: [Elecraft] Weird or wierd - OT

[Don Wilhelm]

Ted,

Until I got my EE Degree, I was a technician in IBM's Typewriter 
division, and I worked on customer's premises for Selectrics as well as 
typebar machines (and dictating equipment).
I can tell you that there was never a "blur" character on the typeball, 
nor a "blur key" on the keyboard for any of the machines.  There WAS a 
lot of talk about it in certain circles, and a desire on the part of 
many operators for such a blur key.

I've tried to teach English to students from 19 different countries,
although not Laos. No matter what the student's native language, it's an
uphill battle. But the strong incentive to learn English is the driving
force that eventually gets over many of the obstacles -- although
"eventually" can be a long time and "many" can be a pretty small number.

Decades ago, a good friend who was a Royal Lao Air Force officer asked 
me if I would assist his daughter with English in preparation for her 
secondary school admissions examination.? I realized early on that I was 
heading for failure while we were on formation of plurals ... dog/dogs, 
cat/cats, person/people, goose/geese, moose/moose, sheep/sheep, ...? The 
Lao language has no plurals so we were starting from scratch.? It was at

to "i before e ... or not, you choose."

So I purchased a KX3 kit recently.  It arrived and I carefully built it.  I
have a well equipped workbench with all the proper tools and instruments

My KX3 worked on receive right the first time, but wouldn't transmit.
After many emails back and forth (on a weekend no less!!) from Wayne and
the crew, it was decided I needed to send it back.  I did so and Joe worked
on the unit.  He found a *demolished* surface mount capacitor on the
control board.  I unpacked my parts from bubble wrap directly onto the
static mat at my workbench and used all the appropriate tools to assemble
(ie, nutdrivers for standoffs, not pliers, etc!!).  I know I didn't cause
the damage.

But, how would they know that?  When Joe called me and then emailed me a
picture, I thought... I'm in for it. There is no way they are going to
believe me that I didn't damage it.  Well, I didn't have to.  Joe didn't
even ask.  He just fixed it under warranty and said "don't know how or when
it happened, we just want you to be happy with your purchase"

This is not the customer service I've become accustomed to with any
vendor!  Huge kudos to the owners and employees of Elecraft.  This kind of
treatment as a customer is unheard of in today's world and I can't say
enough good things about the experience.  Nothing is perfect, eventually
something will sneak by and these guys not only stepped up to the plate,
but went above and beyond to make it right, and make it right FAST!

Thank you all very much.  I appreciate all the help and wanted the group to
know ( I suspect this isn't new news to anyone on this list!!) that
Elecraft has made a new customer out of me that will definitely be a
repeat!

Thanks for taking the time to read this.  It was important to me to
publicly pass my thanks on to these guys!!  Wish more companies were like
this!

Re: [Elecraft] OT: old ARRL RA Handbook info

[Bob via Elecraft]

My 1st was a 1957 given to me as a XMAS present by my grandmother.  In pretty 
sad shape now but I still have it.  My 1st rig setup was all Heathkit, AR3 
receiver, AT1 transmitter and AC1 antenna coupler.  Not the original but I have 
them all now.


However there is a radio piece I've been looking for for years now.  So this is 
a WTB request too.  My 1st piece of radio gear was a Boy Scout Radio kit.  It is 
shown here on page 69:


https://books.google.com/books?id=7lafwNQ6mREC=PA8=PA8=bsa+explorer+radio+kit=bl=Meh1Q3jEQ-=7Ctm006UedcN738sZnpPP_mTTEg=en=X=0ahUKEwiU07Xirf7YAhUK44MKHWjTDXIQ6AEIYzAN#v=onepage=bsa%20explorer%20radio%20kit=false

Anybody have one or clues to a potential source?

This was also a XMAS present and that lead to Ham Radio and eventually to my 
career in electronics and TV broadcasting.


Also have a birthday year Handbook, 1942.

In advance, TNX!

Yes. AND in the hands of a knowledgeable engineer/technician, a near 
lab-quality test instrument, with a display that can easily be 
calibrated to the signal level at the antenna input. I've used it to 
measure occupied bandwidth of transmitted signals to precision of a few 
Hz, and the SVGA board, with it's separate, higher res FFT, improves 
that to one Hz. I own two other dedicated spectrum analyzers -- an HP 
8657A and a Rigol. They are not capable of these measurements, because 
they lack the frequency resolution (by a factor of about 500:1).


Many other modern SDRs also have this capability when used with suitable 
software.

There are two basic reasons to use DSP:

1. As the core of the transceiver’s architecture, to reduce size and weight and 
increase flexibility

2. To provide a number of important features that have typically been seen only 
in desktop radios

Explaining #1 is always a bit of a challenge since it dives into theory. Here’s 
the short version: The receiver in both the KX2 and KX3 uses a high-level 
quadrature mixer that down-converts the RF signal to baseband (0 kHz) or to a 
low I.F. (8 kHz). The resulting I and Q signals are fed to a pair of 
high-performance audio A-to-D converters, and all demodulation is then handled 
in DSP code. This configuration has immense versatility, reduces component 
count, and provides very consistent unit-to-unit performance in parameters such 
as selectivity.

To explain #2, I prefer to just dive into the demo. There's a long list of 
functions that directly benefit those who operate portable, as well as anyone 
trying to maximize their communications capabilities.

Here are the DSP functions that I try to include in demos (given enough time), 
along with their benefits for the operator:

* Multiple Modes

The KX2 and KX3 both support SSB, CW, AM, FM, and several data modes, without 
the need for supplementary hardware. All demodulation is handled by the DSP. 
And if we add a new mode in the future, it will be available to all KX-line 
radio owners free of charge with a simple firmware upgrade.

* Bandwidth Control

The DSP bandwidth can be adjusted from 50 Hz to 4000 Hz (5000 Hz in AM mode). 
The passband can also be shifted. Rigs without DSP are limited to the passband 
of their analog filters (including crystal filters).

* Stereo Audio Effects and Dual Receive

Both rigs demodulate two independent audio channels, allowing for simulated 
stereo, which reduces listening fatigue.

Stereo is also used when DUAL RX is enabled; this allows the operator to listen 
to one signal in the left ear (VFO A) and another in the right (VFO B). This is 
essential for use with DX stations operating split, and greatly facilitates 
hunt ’n’ pounce contest operation where one receiver is parked on a station to 
be worked, while the other is used to locate the next one.

* Adjustable AGC

The KX2/KX3 include user-configurable AGC. Threshold, attack, decay, and hold 
time can all be adjusted. These are parameters that would require dozens of 
components in a non-DSP design. There’s also a short-duration pulse detector 
(AGC PLS). When this is turned on--the default--the DSP will seamlessly remove 
such pulses before they can pin your S-meter and cause a long RX recovery 
delay. (Rob Sherwood complemented us on this feature, which he found was 
missing on even high-end desktop transceivers. So, for in-house purposes, we 
call it “Sherwood mode” :)

* Noise Blanking

Many non-DSP radios lack noise blanking, or have simple blanking circuitry that 
can be easily overloaded. The KX-line DSP implements very effective blanking 
that can take out narrow pulses even at very low settings, and greatly 
attenuate irregular, high-duty cycle noise sources typical of light dimmers, 
electric fences, and wideband radar. Blanking can make the difference between a 
good QSO and not even hearing the other station.

* Noise Reduction

We often have to deal with stochastic (“white”) noise on the bands. Our 
DSP-based NR can be adjusted over a wide range to improve intelligibility, 
especially of speech signals.

* Audio Peaking Filter (APF)

CW operators often have to copy signals right at or even below the noise floor. 
At times like this, our APF can dramatically improve copy without adding 
significant ringing. APF uses a special filter shape for this purpose, with a 
30-Hz-wide peak and broad, low-delay skirts.

* Text Decode/Encode

DSP allows the KX2/KX3 to demodulate and display CW, RTTY, and PSK31/63 signals 
directly on the LCD (or in the case of the KX3, as several lines of text on the 
PX3 panadapter). These modes are also directly supported for transmit purposes, 
using a keyer paddle (a keyboard can also be used, in conjunction with KX2/3 
Utility and a notebook computer).

* Receive and Transmit EQ

8-band EQ is provided to allow the operator to tailor both receive and transmit 
audio to meet special hearing requirements, optimize for use with particular 
microphones, etc.

* CWT (CW/data tuning [auto-spot] and mini-spectral display)

The DSP sends the MCU information

heading for failure while we were on formation of plurals ... dog/dogs, 
cat/cats, person/people, goose/geese, moose/moose, sheep/sheep, ...  The 
Lao language has no plurals so we were starting from scratch.  It was at

Re: [Elecraft] OT: old ARRL RA Handbook info

[Phil Hystad]

My very first ARRL Handbook was 1960.  My last, until the modern era, was 1966. 
 Although I no longer have the originals, I have bought copies in pristine 
condition at hamfests and they sit right next to my original 1966 Allied Radio 
Catalog with the order form sheet still in it ready to be used.  Anyone want to 
order a new Eico 720 transmitter kit, only $79.95.

Re: [Elecraft] K2 - Issue after installing K60XV

[Don Wilhelm]

Neil,

Did you set the secondary menu D19 parameter to "Y"?

If you have the KAT2 installed, be certain the change KAT2 R6 to 470 
ohms, there is a resistor provided in the K60XV kit for that.

Did I screw something up, or is there some menu setting I missed when I

[Elecraft] DSP vs. non-DSP portable transceivers

[Wayne Burdick]

At the Dayton (yeah, OK, Xenia) Hamvention, just before giving a demo of the 
KX2, a bystander asked me, “Why would you need DSP in a portable transceiver?” 
He went on to mention a few currently available rigs he was considering that 
didn’t have DSP, including one very new one [an “upgraded” legacy model]. I’ll 
leave the entire list to the reader’s imagination.

There are two basic reasons to use DSP:

1. As the core of the transceiver’s architecture, to reduce size and weight and 
increase flexibility

2. To provide a number of important features that have typically been seen only 
in desktop radios

Explaining #1 is always a bit of a challenge since it dives into theory. Here’s 
the short version: The receiver in both the KX2 and KX3 uses a high-level 
quadrature mixer that down-converts the RF signal to baseband (0 kHz) or to a 
low I.F. (8 kHz). The resulting I and Q signals are fed to a pair of 
high-performance audio A-to-D converters, and all demodulation is then handled 
in DSP code. This configuration has immense versatility, reduces component 
count, and provides very consistent unit-to-unit performance in parameters such 
as selectivity.

To explain #2, I prefer to just dive into the demo. There's a long list of 
functions that directly benefit those who operate portable, as well as anyone 
trying to maximize their communications capabilities.

Here are the DSP functions that I try to include in demos (given enough time), 
along with their benefits for the operator:

* Multiple Modes

The KX2 and KX3 both support SSB, CW, AM, FM, and several data modes, without 
the need for supplementary hardware. All demodulation is handled by the DSP. 
And if we add a new mode in the future, it will be available to all KX-line 
radio owners free of charge with a simple firmware upgrade.

* Bandwidth Control

The DSP bandwidth can be adjusted from 50 Hz to 4000 Hz (5000 Hz in AM mode). 
The passband can also be shifted. Rigs without DSP are limited to the passband 
of their analog filters (including crystal filters). 

* Stereo Audio Effects and Dual Receive

Both rigs demodulate two independent audio channels, allowing for simulated 
stereo, which reduces listening fatigue. 

Stereo is also used when DUAL RX is enabled; this allows the operator to listen 
to one signal in the left ear (VFO A) and another in the right (VFO B). This is 
essential for use with DX stations operating split, and greatly facilitates 
hunt ’n’ pounce contest operation where one receiver is parked on a station to 
be worked, while the other is used to locate the next one.

* Adjustable AGC

The KX2/KX3 include user-configurable AGC. Threshold, attack, decay, and hold 
time can all be adjusted. These are parameters that would require dozens of 
components in a non-DSP design. There’s also a short-duration pulse detector 
(AGC PLS). When this is turned on--the default--the DSP will seamlessly remove 
such pulses before they can pin your S-meter and cause a long RX recovery 
delay. (Rob Sherwood complemented us on this feature, which he found was 
missing on even high-end desktop transceivers. So, for in-house purposes, we 
call it “Sherwood mode” :)

* Noise Blanking

Many non-DSP radios lack noise blanking, or have simple blanking circuitry that 
can be easily overloaded. The KX-line DSP implements very effective blanking 
that can take out narrow pulses even at very low settings, and greatly 
attenuate irregular, high-duty cycle noise sources typical of light dimmers, 
electric fences, and wideband radar. Blanking can make the difference between a 
good QSO and not even hearing the other station.

* Noise Reduction 

We often have to deal with stochastic (“white”) noise on the bands. Our 
DSP-based NR can be adjusted over a wide range to improve intelligibility, 
especially of speech signals.

* Audio Peaking Filter (APF)

CW operators often have to copy signals right at or even below the noise floor. 
At times like this, our APF can dramatically improve copy without adding 
significant ringing. APF uses a special filter shape for this purpose, with a 
30-Hz-wide peak and broad, low-delay skirts.

* Text Decode/Encode

DSP allows the KX2/KX3 to demodulate and display CW, RTTY, and PSK31/63 signals 
directly on the LCD (or in the case of the KX3, as several lines of text on the 
PX3 panadapter). These modes are also directly supported for transmit purposes, 
using a keyer paddle (a keyboard can also be used, in conjunction with KX2/3 
Utility and a notebook computer).

* Receive and Transmit EQ

8-band EQ is provided to allow the operator to tailor both receive and transmit 
audio to meet special hearing requirements, optimize for use with particular 
microphones, etc.

* CWT (CW/data tuning [auto-spot] and mini-spectral display)

The DSP sends the MCU information about how far off the nearest signal is from 
the user’s selected sidetone or mark tone frequency. We use this to enable 
quick, one-tap auto-spotting of signals, as well 

[Elecraft] When to use the preamps on the KX2/KX3 vs. K3/K3S (Wayne Burdick)

[Michael Aust]

Wayne,
   Have a KX3 here and use the Rx I/Q Ports with external SDR
receiver and applications need I/Q outputs with an HF 3dB splitter with a DXE 
RTR-1A
DXE box with Protection from overload Rx protection 


Noticed poor sensitivity due to the High NF when taking output from Rx I/Q at 
the 
Rx I/Q has great amplitude & Phase Balance ( outstanding ) 


Noted that to increase sensitivity in my Go Box had to add 
a Clifton Labs HF 11dB High IP2/High Ip3 LNA preamp to utilize the
Rx I/Q Ports on super weak Signals.


Found adding an External  Pre-Amp was necessary and with Pre-Amp On in the KX3 
for Bands on 
20meters and Higher was necessary to get enough sensitivity for my necessary Rx 
I/Q 
applications and 3rd Party SDR Synced Receiver being driven by the KX3 and 
WIN4K3 software

Re: [Elecraft] K3S - Help me decide on which options to purchase

[Michael Gillen via Elecraft]

Hi guys!

Received my K3S yesterday afternoon and was on the air in about an hour. Made 
three QSOs with my favorite Net, the OMISS 40m, so everything is working as 
expected. Tuned around the bands later and listened in on the ANZA DX net from 
Australia and also heard a guy from New Zealand both on 20m. Couldn’t stay up 
too late as I have work this AM but was very excited and could have been up a 
lot longer. Just love being back on the air!

Thanks Elecraft and this group for the support and info. Looking forward to 
many years behind the mic.

By the way, I opted for just a minimal configuration right now - the “Casual 
User” package with the "2.8 filter swap”. Its a K3S with the antenna tuner and 
100w amp. Good enough for my current needs.

Re: [Elecraft] Will the KPA 1500 operate RTTY in "run mode" for 48 hours?

[Ed W0YK]

Anecdotally,  I've operated several RTTY contests with a field-test KPA1500 and 
it just loafed along.  I didn't critically examine fan noise.  With 
noise-canceling headphones,  I wasn't aware of any fan noise.  Operationally, 
it felt like QRP, Wayne's target environment.

I have a complete K line with the KPA 500 currently. I am considering
purchasing a KPA 1500. Will the KPA 1500 operate, *on all bands at legal
limit*, while operating as a "run" station in a RTTY contest? That would be
near continuous duty. How loud are the fans when operating in this mode?

Thank you in advance for any information.

A quick trip to CW then hitting a few dits on the paddle produces the

Then returning to DATA A and TUNE and the expected tune power is emitted.

No idea why this would occur and it is a new thing. I have recently updated

[Elecraft] New wierd K3s behavior

[Jim Miller]

When I turn on my K3s (and let it finish booting) and try pressing TUNE
(hold XMIT) I get a zero power indication rather than tune power if in DATA
A mode.

A quick trip to CW then hitting a few dits on the paddle produces the
expected 100w barefoot power.

Then returning to DATA A and TUNE and the expected tune power is emitted.

No idea why this would occur and it is a new thing. I have recently updated
to the latest beta firmware for the enhanced KPA1500 integration. Perhaps a
bug was introduced there?

Ideas?

Re: [Elecraft] KPA500 cooling and efficiency

"That's perfectly normal at that low power output.  The 50% spec is at full 
output."


Thanks for pointing that out. I did a spot check on the same band with KPA500 
indicated output of 490 W (LP-100A 500W) and found the efficiency was 60.6%  
(61.9% if LP-100A power is used).

Re: [Elecraft] KPA1500 fan noises

[Roy Koeppe]

About-

"Take care in the application of added cooling efforts"

Yes, but the proof is in the pudding; watching LEDs display the amp's temp, 
the readings are always cooler with the aux fans running. One reason is that 
between transmissions they continue running and reset the temp back to near 
ambient room temp instead of around 50C where the stock fans shut off. My 
operating is QSK rag-chewing, breaking back forth in round tables. Fans do 
remain off then nearly always. P.S...my 4.5-inch, 48-volt muffins cost a 
whopping $1.86 each! Guess no one wants 48V. If bearings wear out, so what. 
:-)

Re: [Elecraft] KPA500 cooling and efficiency

[Charlie T]

Yes, if you want to run QRP/battery, you are fooling yourself if you crank ANY 
* 100 watt radio down to 10 watts out.

Same with, for example, the TS-480, 200 watt version. It's efficiency, even at 
100 watts out is barely 25%
The signal is probably cleaner, but the efficiency is shot.

*the K3 is the exception since it bypasses the 100W amp when you go LOW (smart 
radio eh?).

That's perfectly normal at that low power output.  The 50% spec is at full 
output.  If you ran your TS-590S at 20 W output, you would probably see about 
the same low efficiency.

[Elecraft] Will the KPA 1500 operate RTTY in "run mode" for 48 hours?

[j...@kk9a.com]

Great question, I would also like to use one for this purpose. If you're
only using one radio it will get little rest. I am sure that it will
survive a RTTY contest however I would probably set the fan at a higher
continuous speed and live with the fan noise however I wonder how loud
this really is. The initial testers claimed that the amp was very quiet. I
also wonder if the KPA1500 crackles while cooling down like the KPA500.

near continuous duty. How loud are the fans when operating in this mode?

Thank you in advance for any information.

Hi Mack,

To my ears, very loud when speed gets up to #4 during a very long CW 
transmission.
