Re: [Elecraft] Question about 120 volts vs. 240 volts house supply toKPA 500

[Bill Breeden]

Same here, my K4, KPA500, and everything else in my radio room operates 
one 120V 20A circuit.


My KPA500 has been powered from 120V since it arrived here new in 2011.

Dear Folks:

I have operated my KPA 500 off of a normal wall out let (120 volts) 
for years now and have gotten good service.  However, I've often 
wondered if there would be a definite advantage to getting 240 volt 
service into the shack, so that I could operate the amp off of that 
supply, as opposed to a normal wall outlet. I recognize that there 
would be less current draw.  My question would be whether it would 
lessen the wear and tear on the amp if I switched to 240 volts?


Thanks and 73 de Bernie, KF0QS

the process, I managed to pop loose the cable that goes from VCO Out

find an empty TMP jack anywhere on the RF board. Judging by the length

side of the main board, toward the left \, but there's nothing there.


The problem is that the updated KSYN3A synthesizers in my K3 were 
installed at the factory, so I don't have the usual documentation and 
the units look very different from the originals  (my assembly manual 
only covers the original synthesizers, and also looks much different 
in the section dealing with the cabling of the synthesizers)


Can anyone tell me where that cable is supposed to go?

I do the same.  That being said, I am very satisfied with the power

Re: [Elecraft] K4 model v. K3S for strong nearby signal rejection.

I asked a similar question at the Elecraft K4 Forum at the Huntsville

Since Eric, Wa6HHQ presented the forum and answered my question, he can

Re: [Elecraft] New product idea for Elecraft...?

[Bill Breeden]

I guess that's the beauty of a complete K line station.  I change bands 
with the buttons on the KPA500 and verify that I'm not transmitting on 
the DX by observing the cursors on the P3.  After setting up the K3 the 
way I wanted it, I now access the menus less than once a month.

DX.  Probably half the, "He's split you moron" comments in pileups are 
directed at K3 owners. And don't even get me started about memory

So I bought a KPod.  I'll spare you the agony of reading about the 
tribulations I had with that. It took me making a video clip of the 
malfunction to convince Elecraft that the issue I was seeing was 
real.  Fixed with new firmware in the K3S not the KPod. Nevertheless 
it's a promise unfulfilled.  It's simply a trigger for macros you have 
to write and save in the limited space for macros in the radio.  The 
KPod doesn't save anything.


The other aftermarket keypad solution requires that you own a P3.

I don't mind things infrequently accessed being buried in menus. But 
how about a knob to change bands?  We have a couple of knobs for fine 
frequency adjustment, why not one for coarse adjustment?

ever hearing anyone complain about excess knobs, buttons, dials,

Elecraft or some third party make a "magic box" that would be 
completely impotent by itself, but with the capability to mate up to 
one of these small miniaturized wonders like the KX2 or KX3, and 
which would contain oodles of manual controls for virtually every 
function the parent rig is capable of providing?
  This would NOT impact the normal functioning of the parent rig, 
but would act as an accessory for those who eschew menus and such, 
and who like their rigs bigger, bulkier and in more traditional 
formats. I envision a box of switches, buttons, knobs, perhaps even 
gauges that would be cable-fed (or wi-fied) from the little parent 
rig sitting behind the magic box. Its size would be whatever was 
necessary to accommodate the design and would resemble a 
normal-sized base station. You could conceivably have a separate 
control for each function the parent rig provides, or if logic 
dictated, then several controls might be multi-purpose.
  Then an op could have the best of both worlds. He/she could use 
his/her KX2/KX3 as a portable rig in the normal way, but when 
returned to the home station, it could be plugged back into the 
magic box to power it in a more expansive and convenient manner.
  Elecraft seems to always be on the lookout for new products. 
Here's one they might be able to put on the market, up and running, 
quickly because most of the engineering has already been worked out 
for the parent rig.

Re: [Elecraft] P3 setup

[Bill Breeden]

Chuck,

With the P3 in "Tracking" mode, you can active the "Center" function 
with the SPAN/CENTER button (third button down the right) and then use 
the knob to move the cursor anywhere you want.  I have several useful 
"Span" widths stored in some of the "FN" buttons so that I don't have to 
leave "Center" mode to change the "Span".  That allows me to quickly 
re-position the cursor after changing the "Span" to accommodate the size 
of a particular pileup.

With one exception, every transmitter and receiver I've ever seen has

Current flows in loops -- the center conductor feeds one side of the

transmitter, a military surplus BC-459, which had a single terminal 
fed from the output of an internal matching network. The return for 
output current was the chassis, which was mounted to the chassis of 
the military vehicle or aircraft in which it was used, and the chassis 
of that vehicle or aircraft acted as the other half of the antenna.


The suggestion to use a BNC to female "dual Banana" adapter is a very 
good one. I've used one for exactly this purpose with my K2 and KX3

Re: [Elecraft] 1 Khz filter

[Bill Breeden]

Jim,

I think most K3 owners understand that.  Those who call CQ during 
crowded band conditions also understand that their ears will take less 
of a beating when using a 1 kHz DSP bandwidth in conjunction with a 1 
kHz roofing filter instead of the next wider roofing filter, which, in a 
K3 is often a 2.7 or 2.8 kHz filter.  That's the wonderful thing about a 
K3, the owner can equip it according to his or her personal preference.  
My ears have taking enough beatings over the years from stations outside 
of the filter bandwidth pumping the AGC while using lesser receivers to 
know that I prefer a tight roofing filter bandwidth so that the stations 
outside of my DSP bandwidth have minimal effect on what I am hearing.   
I have used my "Field Day" K3 to call CQ during crowd banded conditions 
before and after I added the 1 kHz filter and have found the improvement 
well worth the price of the filter.  Your mileage may vary.

It's important to remember that IF bandwidth is determined by DSP, and 
continuously adjustable. The plug-in filters are ROOFING filters -- 
their primary function is to protect the DSP from overload by very 
strong stations outside the bandwidth of the DSP IF. They have the 
secondary function of adding the filtering provided by the DSP, and 
when the DSP and the roofing filter are at the same bandwidth, the 
filter skirts become steeper (sharper).


Bottom line -- we don't need to buy a 1 kHz filter to get 1 kHz IF 
bandwidth, because the DSP already provides that. This is not your 
grandfather's radio! :)

Hello John,

It's used for CW. I have a pair of them (main and sub rx) and find 
that CW
sounds more pleasing through this filter. I operate about 90% CW and 
I use

this filter most of the time, engaging narrower filters only when it
becomes really necessary.

Re: [Elecraft] [Elecraft_K3] New from Elecraft: KPA1500 amplifier with built-in ATU, separate power supply

[Bill Breeden]

An excellent point missed by many of the desktop tuner and high feedline 
SWR advocates who insist on using coax fed antennas. Typically, they 
blame their failures on cheap coax.

typically rated at 1500W with a 1:1 SWR.


It's true that you can do more than that with low-duty-factor modes 
like CW and SSB, but if you are running much more than 3:1 SWR you may 
be in danger of damaging the feedline.

If the "tuner" components have to be derated to this extent then
perhaps it should be called a line flattener rather than a tuner
because a lot of guys are still going to need a tuner.

Hi all,

I reviewed the webpage on the Heil Sound website here: 
https://heilsound.com/heil-amateur-radio/support/dsp-settings/all-things-elecraft/
  Unfortunately, the page refers to the mic with regard to the front panel 
setting, but does not specifically refer to the mic model with respect to the 
mic gain and mic bias settings. I sent an email to Heil Sound suggesting that 
the missing detail be added for this particular mic. But thought I'd ask here, 
in case anyone knew the answer. I deduced that the setting should be Front 
Panel, Low, No Bias, but am not 100% sure about that!
Here's the strange part about this story. I did have a QSO with a station in 
North Dakota after setting up the rig, so we knew all was working. We shut off 
the rig and I left for home. Later in the evening, my godfather turned the K3 
on and tried to transmit, but noticed that he wasn't getting any moving bars 
with the transmit audio. I walked him through putting the K3 into test mode, 
turning down the mic gain, and then turning up the mic gain while he was 
transmitting to find the optimum level, but we couldn't get the meter to show 
any response to the audio. I did the same procedure on my own K3 to make sure I 
was talking him through the right steps and it worked fine on mine. He did try 
a Heil headset with the same results. I plan to try and get up to visit again 
this weekend and bring a hand mic with me to try and make sure that it is 
definitely the K3 and not the mic.
So unless I'm missing something obvious

Re: [Elecraft] K3 loss of rx signal

I too had an issue with a couple of cables between my K3 and P3. Had to 
wiggle the cable every few days to get rid of the extra noise on the 
P3.  Finally replaced the cable with a 3 foot Amphenol BNC cable, part 
number 115101-30-36.00 and have never had the issue again.  The cable is 
made with LMR-100, which is skinny and flexible.  It's currently in 
stock at Mouser for $18.66.

Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3

I can't say enough good things about a CrankIR vertical either. Have

Even had it installed over my permanent radial field for about a month 
while my SteppIR vertical was being repaired after some wind damage.

If you want to be sure you'll have a successful outing with the declining band

Its not the lightest or easiest to deploy but it could very well be the best performing portable self supporting antenna out there. Once set up its fully resonant on your band of choice and easy to change bands.  I stripped mine down for 40-6m at 10lbs and fit in a charter sized suite case on a recent trip to HI9 land.


With the kx3 running 10w I rarely had to call CQ more then 3 times and was 
creating pileups. Its large footprint does attract a bit of attention on the 
beach and most folks thought I was setting up a deep sea fishing rod (its a 
real chick magnet lol).  Theres definitely no performance compromise with this 
portable antenna if you can tolerate the extra weight and setup time.

I also tried the random wire in a tree one afternoon there which worked 
surprisingly well too but had to work a lot harder for contacts. This was all 
SSB.

Can Anyone recommended a great QRP Antenna for KX3

Going to Hawaii with KX3 from high rise Hotels and some Sandy Beaches
that is lightweight, easy to deploy, carry on Airlines or packed into luggage.

Any Portable Poles to recommend for End Fed Antenna's

My MFJ-1920 pole is 3.8ft when collapsed and extends to 33 feet
but when Island Hopping, 3.8ft does not qualify as a Carry On due to it's length
So hit with extra baggage fee's

Maybe a Fishing pole that is on sections that not as long, when collapsed
would be the Answer, some 14ft to 17 feet Crappie Fishing poles only
breakdown to 46inches to 48inches, about the collapsed length of my
MFJ-1910 fiberglass telescopic mast

Right click on the Norton icon on the task bar and select the "Disable

[Elecraft] KPA1500

[Bill Breeden]

Eric, WA6HHQ, gave a presentation titled "High Performance Ham Radio: 
Inside KPA500 & Elecraft K-Line" at various hamfests in 2011, including 
Huntsville where I attended.  He explained that before Elecraft settled 
on the KPA500 they built three different sized prototype amplifiers for 
proof of concept and to establish the cost for each.  He explained that 
when that effort was complete the KPA500 was thought to be the best fit 
for the market at that time. When a member of the audience asked what 
happened to the legal limit amplifier, Eric replied that it was in his 
shack.  Eric can correct me if I have failed to remember his 
presentation accurately.

Re: [Elecraft] K3 - AFSK anomaly? No replies, try again

[Bill Breeden]

Mike,

Glad to help and glad it made sense!

When you tune across an RTTY signal using your 400 Hz filter with the 
dual passband filter turned off, first one shift, either Mark or Space 
depending on the direction you are tuning,  will enter the passband of 
the filter and then both shifts.  Assuming you have the Shift control on 
the front of the K3 centered, when the Mark and Space energy is centered 
on either side of the center of the filter (and the decoder), the RTTY 
will decode properly.  Besides seeing the decoded text, the CWT 
indicator in the meter area of the K3 display will show you when you 
have the Mark and Space energy centered for proper decode.   As you 
continue to tune same direction, you will lose the first shift you 
acquired as it passes out of the other side of the filter passband, and 
then finally you will lose the other shift as you continue to tune away.

Excellent analysis and I suspect you are correct in exposing my

about the problem, it makes sense that the radio is doing exactly what 
it is supposed to when I hear the inverted tones 170 Hz down from the 
original signal.  Rich, VE3KI, suggested turning off the dual passband

Mark energy and the Space properly aligned in the dual passband
filter and the data conveyed by the mark and space energy is being
decoded and displayed.  In a normal "ham radio" RTTY signal the RF
energy for the Mark and Space is 170 Hz apart, with the Mark
frequency 170 Hz higher, in RF terms, than the Space frequency. 
When demodulated by a receiver operating in Lower Sideband (LSB)

mode, this results in two audio tones, with the audio tone
representing the Space energy 170 Hz higher than the audio tone
representing the Mark energy.  In the video, when your radio is
tuned to 14,091.883, the tone representing the Mark energy is
passing through the "Mark" side of the dual passband filter and
the tone representing the Space energy is passing through the
"Space" side of the dual passband filter, and the RTTY data is
decoded properly.  When you tune down to 14,091.720 in the video,
a 163 Hz difference, you have the tone representing the Space
energy passing through the "Mark" side of the dual passband filter
and the tone representing the Space energy is outside of either
portion of the dual passband filter.  There is no anomaly revealed
in your video, that's just the way that RTTY, the receiver, and
the dual passband filter works when you tune away from a properly
tuned RTTY signal.

The reason the data on the Space tone sounds like an inverted
version of the data on the Mark tone is because that is exactly
what it is.  In an RTTY signal, the same data is carried by the
both the Mark and Space energy and the state of one is the
inverted state of the other.

is 170 Hz apart, with the Mark frequency 170 Hz higher, in RF terms, 
than the Space frequency.  When demodulated by a receiver operating in 
Lower Sideband (LSB) mode, this results in two audio tones, with the 
audio tone representing the Space energy 170 Hz higher than the audio 
tone representing the Mark energy.  In the video, when your radio is 
tuned to 14,091.883, the tone representing the Mark energy is passing 
through the "Mark" side of the dual passband filter and the tone 
representing the Space energy is passing through the "Space" side of the 
dual passband filter, and the RTTY data is decoded properly.  When you 
tune down to 14,091.720 in the video, a 163 Hz difference, you have the 
tone representing the Space energy passing through the "Mark" side of 
the dual passband filter and the tone representing the Space energy is 
outside of either portion of the dual passband filter.  There is no 
anomaly revealed in your video, that's just the way that RTTY, the 
receiver, and the dual passband filter works when you tune away from a 
properly tuned RTTY signal.


The reason the data on the Space tone sounds like an inverted version of 
the data on the Mark tone is because that is exactly what it is.  In an 
RTTY signal, the same data is carried by the both the Mark and Space 
energy and the state of one is the inverted state of the other.

After doing some more testing in last weekends RTTY contest, it appears
that I made an erroneous statement as to what I was hearing and where.
What I found is that as I tune down in frequency and find a signal that
will decode, if I then tune down another 170 Hz I'll hear the inverted
signal.  Still using dual passband DSP filter at 400 Hz and 400 Hz, 8 pole
roofing filter as before.  I have a brief video on uTube showing the effect
at:

Anyone have additional thoughts as to what's causing this or where I should

Re: [Elecraft] RTTY Hang time

[Bill Breeden]

Bill,

If you are using the CW memory keys M1-M4 to send RTTY, add a "pipe" 
character ( I ) at the end of the message.  The K3 will ignore the 
"pipe" character in CW mode, but will end the transmission immediately 
when it encounters it in RTTY (FSK D) mode.  The "pipe" character is the 
upper case character on the same key as the backslash character.  You 
can use the "Edit CW Memories..." function in the K3 Utility to add this 
character to your messages.


73,

Bill - NA5DX



I'm sure this has been brought up before but I've been told that there's a
hang time issue when I'm done transmitting RTTY.  Some folks use a keyer and
type IM.  There's got to be a way to go to the config Macro to include this
so I don't have to do it manually.  Can someone walk me through the process
of doing this once and for all?



Thanks,



Bill

[Elecraft] K3S DSP filter plots

[Bill Breeden]

Charles,

Here are some quick and dirty readings from my Field Day K3 which is 
equipped with a 400 Hz filter, but nothing narrower.


Both sets of S meter readings below start with the K3 in CW mode tuned 
to 3550.000 with the S meter reading S9+40 from a 3550.0 signal supplied 
by an HP8640B.  As you suggested, I then tuned the K3 away from the 
signal from the generator.


400 Hz filter in "normal" configuration (400 Hz DSP also):

+40 = 3550.000
+35 = 3550.134
+30 = 3550.166
+25 = 3550.177
+20 = 3550.182
+15 = 3550.185
+10 = 3550.190
  +5 = 3550.195
  S9 = 3550.198
  S8 = 3550.204
  S7 = 3550.208
  S6 = 3550.213
  S5 = 3550.224

400 Hz filter with DSP narrowed to 200 Hz:

+40 = 3550.000
+35 = 3550.068
+30 = 3550.080
+25 = 3550.094
+20 = 3550.104
+15 = 3550.112
+10 = 3550.120
  +5 = 3550.126
  S9 = 3550.130
  S8 = 3550.138
  S7 = 3550.142
  S6 = 3550.145
  S5 = 3550.150

I only had time this morning to measure two filter settings on one slope 
of each filter.  I'll let you plot the data.


I hope you find this information useful until you get some better 
information.

Thanks for the reply Joe.

I'm hoping that the constant slope you described is not the way the DSP
filters are implemented, because that would mean the 50hz filter has a
5.625:1 shape factor, the the 100hz filter has a 5:1 shape factor, the
200 hz filter has a 3:1 shape factor and the 400hz filter would have a
2:1 shape factor. To achieve better than 2:1 shape factor at 30dB per
100hz, the width of the DSP filter would need to exceed 400hz.

I wonder if anyone has put their K3 or K3S in the 1 hz tuning mode with
a signal generator and ploted out the approximate response curves using
the S meter. It's a rather crude way to do it, but in the absence of
more accurate test gear it will give some idea of the shape factor of
the DSP filters.

I will be ordering a K3S today and will ask Elecraft if they have plots
for the 50, 100, 150, and 200 hz DSP filters. If not, I will get the
little signal generator and report my findings on the reflector.

If anyone reading this thread has plotted out the 50, 100, 150, or 200
hz DSP filter response curves, please let me know.

[Elecraft] P3TXMON Question?

[Bill Breeden]

Bob,

I use my Bird 43 terminated with a dummy load when the power level I 
want to measure will give a good meter deflection with the slugs I have 
available.


Like Don, I find the voltage method handy when working with QRP rigs, 
since they barely deflect the Bird with any slug I have.  I use an 
ME-26D/U Vacuum Tube Voltmeter, the military version of the HP-410B, to 
measure the RF voltage across an accurate 50 ohm dummy load and do the math.


With my K line gear, I use the meter in my KPA500 on a daily basis and 
give it an occasional double check with the Bird to make sure both are 
working as intended.


73,

Bill - NA5DX


A comment here, has anyone thought to use a Bird 43P with a 100 watt HF
slug?  Or maybe a TelePost LP-100a?  Both are equally good regarding
power measurements but only when the load is 50 ohms resistive.

[Elecraft] P3TXMON question?

[Bill Breeden]

It's important to remember that RF power expressed in watts is always 
based on RMS values.  If RF watts are calculated by measuring the 
voltage across a known load, the voltage must be expressed as an RMS 
value to correctly calculate the power in watts.  Watts are watts.  
There is no such thing as "peak to peak" or "RMS watts" when expressing 
RF power in watts.


Peak envelope power (PEP) has nothing to do with the difference between 
the peak and average voltage of a sine wave.  It is the measure of the 
power of an RF signal at the modulation peak, averaged over one RF 
cycle.  The power measurement within that one RF cycle is still based on 
RMS values.

[Elecraft] K3S OR K3

[Bill Breeden]

I can't say enough good things about the built in data modes.  I don't 
think "casual" gives them enough credit for their usefulness while 
chasing DX.  I had 114 DXCC entities confirmed in digital mode (all 
RTTY) when I acquired my first K3 in the fall of 2011.  I'm now listed 
at 215 on the digital mode DXCC list and every one I have added was 
worked from the front panel of my K3 in RTTY mode with no interface or 
software.  I have my call sign (x3) built into the M3 button and a 
generic report built into the M4 button, and the K3 is always ready to 
go in RTTY mode when I am on the air.  That readiness made all the 
difference when I worked 9N1AA in Nepal simplex on 20 meter RTTY for an 
all time new one in 2013.  In another minute the frequency was hopeless 
with callers, but my contact was already in the log.  No super station 
here either, worked him from South Mississippi with 500 watts to a 
ground mounted vertical while listening on a wire.

The K3S and K3 also draw a lot less current than your average high-performance 
desktop radio, typically 900-1200 mA in RX mode. This can greatly extend 
operating time for lightweight DXpedition, RV, or Field Day stations that are 
battery powered.

A few other features come into play during field operation:

- four one-touch CW/DATA/voice message memory switches with auto-repeat (M1-M4)

- up to 8 programmable front panel switch macros for doing things like "VFO A->B, 
VFO B up 2 kHz, turn on split" (etc.) with a single switch press; these can be 
customized for different kinds of operation

- built in clock/calendar, voltage, and current display (on VFO B)

- built in data modes for casual operation on PSK31 or RTTY without a computer 
(every Field Day, when I get tired of working CW or SSB, I'll prowl the 
20-meter data sub-bands and work stations with the keyer paddle and message 
memories; you can also use the P3/SVGA with a keyboard)

[Elecraft] K3S band Change with DX4WIN

[Bill Breeden]

Joe,

Good point.  I should have made some more tests before replying. After 
another look, when I select a spot that requires a band change, my K3 
stays in CW mode if the destination band was already in CW mode.


Thanks and 73,

Does the K3 actually switch to SSB or does it switch to the last used
mode on the "new" band before actually switching to the requested mode?

The K3/K3S stores mode by band and will recall the last used mode each
time you switch bands.

Re: [Elecraft] K3S band Change with DX4WIN

Byron,

I never noticed the behavior you described until you pointed it out, but 
I see now that my K3 works the same way.  I have been using the file 
"Elecraft K3 X5" with DX4WIN to drive my K3 for several years. I suspect 
the radio is doing exactly what DX4WIN is requesting.

[Elecraft] K3S band Change with DX4WIN

Byron Peebles NZ3O at arrl.net
Tue Aug 4 21:42:32 EDT 2015

I am researching an issue I experience when I click a spot in DX4WIN.

When I click a spot, switch bands, even CW-to-CW, the K3S switches first
to the band, then SSB, and then CW.
The momentary switch to SSB is probably something in the radio file I am
using, new to me, but I wanted to see if anyone else had this issue.  I
am using the DX4WIN file "Elecraft K3 X5".

TIA, 72, Byron

Re: [Elecraft] I wonder how many folks have had buyers remorse on a K3/K3S purchase?

[Bill Breeden]

Absolutely no regrets here!

I have two friends and fellow hams that are often chasing the same DX 
stations that I am in split CW pileups.  One is three miles away and the 
other, with a super station, is about 10 miles away.  My primary radio 
before purchasing my first K3 in 2011 was an FT-1000. My friends 
signals, while outside of the pass band of the FT-1000's CW filter, 
would pound the FT-1000's AGC and make it difficult to copy the DX 
station we were chasing, especially on the low bands where we are all 
using omnidirectional antennas.  Before ordering my K3, I test drove an 
IC-7800 for 40 days and the effect on the AGC was diminished, but still 
quite noticeable when we were in a pileup together.  Now, with a 400 Hz 
filter in my K3, the only way I know we are in a pileup together is when 
I see them on the P3.  I like the K3 so much that I bought a second one 
for Field Day and other portable events so that I don't have to tear 
apart my home station every time I want to operate portable with a K3.

Re: [Elecraft] 200 Hz 5-pole filter

[Bill Breeden]

Wes,

Rob Sherwood's presentation at the following link answers the "why" 
question a lot better than I can:


http://www.sherweng.com/RochesterMN2009/NC0B-W0DXCC-4dRochester_MN.pdf

At the following link, Eric explains why selecting a narrow filter for 
CW operation in a K3 offers superior performance over selecting a wide 
(sideband) filter and adjusting the DSP to a narrow bandwidth:


http://www.elecraft.com/K3/Roofing_Filters.htm

The point I am trying to make is that a K3 with a 2.7 KHz filter and the 
DSP cranked down to 400 Hz will not perform as well for CW during 
crowded band conditions as a K3 with a 400 Hz filter.

Not really -- the K3, K3S, and KX3 IF filters are implemented in DSP.
The plug-in filters are additional roofing filters that protect the DSP
from overload by strong signals outside of their passband. The K3, K3S,
and KX3 have very good CW receivers without the optional roofing
filters. The roofing filters simply allow them to work very close to
very strong signals, AND cascade with the DSP filter to provide
additional rejection outside the passband.

Apples and oranges.

The K3 is still no 2 with the 200 Hz 5-pole filter.  You just can no longer
buy the radio with that filter.

I have always found it a little strange that Sherwood never stated that
the filters used in his test were optional on the K3?

If the K3 was tested with the stock filter it may make it into the top 10.

Don't get me wrong I have a K3S on order.  I'm just looking at the data

Re: [Elecraft] KPA1500

[Bill Breeden]

Eric, WA6HHQ, gave a presentation titled "High Performance Ham Radio: 
Inside KPA500 & Elecraft K-Line" at various hamfests in 2011, including 
Huntsville where I attended.  He explained that they built three 
different sized prototype amplifiers for proof of concept and to 
establish the cost for each.  He indicated that when that effort was 
complete the KPA500 was thought to be the best fit for the market at 
that time.  When asked what happened to the legal limit amplifier, he 
said that it was in his shack.  Eric can correct me if I have failed to 
remember his presentation accurately.


The Huntsville hamfest in 2011 was very memorable for me.  I was ready 
to buy a new radio to replace my FT-1000 and had narrowed the field to 
the FT-5000 and K3 by the time I arrived at the hamfest. After attending 
Eric's presentation and speaking with him twice at the Elecraft booth, 
my mind was made up.  I slept on my decision a few nights and ordered a 
K3, P3, and KPA500 later that week.  I have never regretted that decision.

It's my understanding that Elecraft did indeed have such an amplifier on
display at Dayton a few years ago.  I don't recall the reason it wasn't
brought to market.

Re: [Elecraft] Bug mode on K3?

[Bill Breeden]

I agree, the single lever Kent (SP-1) is a good value for the price.  
Very well made and has a good solid feel.

Agreed on "bang for the buck"; another in that category IMHO is the Kent SP-1.
I have both, with a slight edge to the Kent, but YMMV. And, for the op who
wants the feel of a bug with an electronic keyer, the Vibroplex "VibroKeyer"
is still in production... fifty years after it was introduced

Re: [Elecraft] Bug mode on K3?

[Bill Breeden]

A real "bug" works fine works fine in the straight key jack, but some 
would like their paddles to send automatic dits and manual dahs like a bug.

Re: [Elecraft] Bug mode on K3?

[Bill Breeden]

I have tried that, but (at least on my K3) there is a timing interaction 
between the paddle input and the straight key input that delays the 
first dah when crossing over from a dit to a dah in same character.  
There is no issue when crossing over from a dah to a dit.  In other 
words, I could send a "B" just fine, but couldn't send "V".  There maybe 
some adjustment I could have made, but I didn't pursue it.  The delay I 
encountered isn't related to the semi break-in delay adjustment on the 
front panel.

[Elecraft] K3 Microphone Hum

[Bill Breeden]

I noticed an AC hum in the monitor audio in my headphones while calling 
with one of the W1AW portables.  While wondering if the hum was really 
in my transmit audio, the W1AW Operator came back to me and reported the 
hum.  I use a Heil Proset K2/K3 via the front panel microphone connector 
through a Kenwood style (red band) Heil pigtail.  After completing the 
QSO I switched to Test mode and I could still hear the hum when I 
transmitted.  Thinking I had a poor connection, I disconnected and 
reconnected both ends of the pigtail, but the hum persisted.  While 
doing that I noticed there was no hum if I activated the push to talk 
with microphone unplugged from the pigtail.  That had me baffled for a 
few moments until I remembered that the Proset K2/K3 requires bias 
voltage from the K3.  At that point I used the "2" button in the "MIC 
SEL" menu to turn the bias off and on a few times and the hum was 
disappeared.  I haven't researched the details of the bias switching 
arrangement in the K3 but it appears that mine needed some exercise to 
clear a bad connection.  I thought I would pass this on to the rest of 
the group in case someone else encounters this issue.

[Elecraft] W1AW/5 MS With K3, P3, and KPA500.

[Bill Breeden]

I operated as W1AW/5 from here on the Mississippi Gulf Coast last night 
on 160 CW from 03-04z, and today on 30 CW from 13-15z and on 17 CW from 
17-19z.


It was my first experience running stations split.  What a pleasure with 
a K3, P3, and KPA500!  I logged 555 QSO's in total.


I hope I worked several of you.  I recall working W4TV on 160 and 30.

Re: [Elecraft] K3 rtty decode vs: computer decode

[Bill Breeden]

Jim,

My observations from a side by side comparison between my K3's internal 
decode and MMTTY are similar to yours.  That being said, the ability to 
decode and then quickly call in RTTY or PSK31 mode when an opportunity 
presents itself using the K3 by itself has been very useful to me.  My 
best confirmed contact in RTTY mode is 9N1AA in Nepal and I would have 
missed him if I had waited to bring up my computer with RTTY software.  
Looking at my log from the point when I started using my K3, I see that 
I have worked and confirmed 75 additional digital mode entities, 
bringing my DXCC digital mode total to 185.  Nearly all of those new 
ones were worked from the front panel of my K3.  I usually don't bother 
to bring up my RTTY software unless I intend to participate in a digital 
mode contest or QSO party.  I wish the K3 had PSK63 mode built in as well.


I don't know if I would feel the same way if I didn't have a P3.  I find 
the P3 an almost indispensable tuning indicator for the digital modes.

Bill - NA5DX

Subject: [Elecraft] K3 rtty decode vs: computer decode

I have played just a bit with the rtty via cw function of the K3 and am curious 
if my casual observations match those of others. It appears that the K3 onboard 
decoder takes a back seat in rtty decode ability to a radio/computer/mtty 
combination. Agree/disagree/thoughts?

Re: [Elecraft] K3 Filters for digital work

[Bill Breeden]

Dave,

I have 200 Hz and 400 Hz filters in my K3.  My K3 copies RTTY fine through the 
200 Hz filter.  That being said, I normally use the 400 Hz filter unless the 
band is crammed with signals during a contest.  The 200 Hz filter also reduces 
a the apparent signal to noise ratio between my ears when working CW on the low 
bands during very noisy conditions.

73,

Bill - NA5DX
 


Which two of the 200/250/400 and 500 hz filters are best for digital
use, primarily RTTY, both contests and dx.  I understand that for JT-65
and PSK the standard ssb filter, or even the AM filter is useable.  I am
concerned that the 200 hz might be too narrow for RTTY.  I work some CW
but almost no ssb.



73, Dave, K2YG

[Elecraft] Link-Unlink

[Bill Breeden]

I have been in at least four pileups where a DXpedition operator has 
inadvertently linked his VFOs.  I believe the first time I observed it was 
during the HK0NA operation.  It was a baffling experience the first time it 
happened, but I think that a number of K3 owners figured out what was going on 
quickly.  I use the Sub button a lot myself and find that I sometimes Link 
inadvertently as well, especially when I'm tired.  I'm not suggesting moving 
anything or creating another menu item, simply requiring a longer hold of the 
Sub button to Link would solve the problem for me.

Re: [Elecraft] [P3] Left Edge Function?

[Bill Breeden]

Jim,

A Left Edge function as you have described is a great idea and would really 
be handy.  I presently use the Center function the same way you do.  I keep 
four useful span settings in my FN3/FN7 and FN4/FN8 keys so that I don't 
have to jump back and forth between the Center and Span functions when 
adjusting the display to the size of the pileup.

Re: [Elecraft] 5 watts to KPA500

[Bill Breeden]

Here are some measurements I made a couple of weeks ago with my FT-817 and 
KPA500:

Band: FT-817 Out = KPA500 Out

160 Meters: 6.0 Watts = 70 Watts.
80 Meters: 5.8 Watts = 75 Watts.
40 Meters: 5.3 Watts = 75 Watts.
30 Meters: 5.1 Watts = 75 Watts.
20 Meters: 5.1 Watts = 75 Watts.
17 Meters: 5.0 Watts = 80 Watts.
15 Meters: 5.0 Watts = 80 Watts.
12 Meters: 4.9 Watts = 90 Watts.
10 Meters: 4.9 Watts = 100 Watts.
6 Meters: 4.2 Watts = 125 Watts.

The power output from my FT-817 was measured with an Oak Hills Research WM-2 
QRP Wattmeter inserted between the FT-817 and the KPA500. The power output from 
the KPA500 into a MFJ-264 dummy load was measured with the KPA500's internal 
wattmeter and read from the digital readout on the front panel of the KPA500. 
All measurements were made with the FT-817 key down in CW mode on a frequency 
in the CW segment of each band.

I use my KPA500 with my K3, not my FT-817, but an amplifier discussion on the 
FT-817 group led me to make this test to satisfy my own curiosity.

Bill - NA5DX
