[Elecraft] # 5607 first contact QRP!

[Dale - K7DNH]

While on a business trip to Lake Havasau City, AZ I made my first ever QRP
contact this evening, and with my newly assembled KX3 # 5607 with W1AW/4 in
Georgia.  Using 5 watts and received "59 - nice signal for QRP from out
west". Of course he has a beam pointed to the west so that helped a great
deal.. but I was still pretty excited about it! Took me about 15 minutes to
get through the "west coast wall" but that is to be expected.

Now to start learning where QRP folks hang out in the bands. I did join the
KX3 yahoo group and looking forward to learning more about QRP.

Thanks for letting me beat my chest a little.

Re: [Elecraft] # 5607 first contact QRP!

[Dave]

Try these frequencies as a starting point. These are the popular CW QRP 
frequencies for the HF bands.


1.843MHz or 1.836MHz
3.560MHz
7.030MHz
10.106MHz or 10.116MHz
14.060MHz
18.096MHz
21.060MHz
24.906MHz
28.060MHz

There may be others as well.

Re: [Elecraft] RTTY with the K3 alone

[Salvatore Irato]

Hi all.
Yes Jim you right.

Even with some difficulties, i.e. re-key each time the call sign of
the correspondent, it work better with an external keyboard. THis
using the K3/P# combo without a PC.

On the other side, using even a Net PC with just MMTTY,
But also the old and trusted MMTTY may work flawlessly. Both FSK or
AFSK. 2Tone is a great decoder and a great companion for MMTTY in FSK.
Those different setups depend on relevant interfaces that each of us
have on hands, PC capabilities and, why not, real estate of the
monitor/screen we have  ... that's clear. But still MMTTY alone and in
AFSK is well working. Not having all the N1MM Logger needs about
setup. Thus loosing the great 2Tone. But, please, when going with a PC
and MMTTY alone take care to get into the TX tones setup:
Option (O) > Setup MMTTY(O) > TX tab >  TXbpf.
There the standard  tap default value is 48, pushing the "f" key on
the left will show the simulated filter curve. To have a better AFSK
bandwidth set the tap value to 256 and up, press again the f button to
show simulated curves and effects on the output tones bandwidth. Tight
is better, bigger tap values are better. But they are somewhat CPU
intensive, be smart and use intermediate values with older
laptops.Make it better for others than the default, but be lower than
512 taps on single core, i.e. slow, machines.

Re: [Elecraft] KX3 doesn't like sand

[jimk8mr]

 This is why when I operated from the beach in Punta Cana as HI/K8MR in the 
2014 ARRL and CQ CW DX contests, I took care to tape over all unused 
connectors, the seam where the two halves hinge together, and the speaker (I 
was using ear buds). While I did not do so, it might also be good to put some 
clear tape over the LEDs that stick through the front panel.

I then placed the radio inside a large ZipLock bag, open only enough to let the 
cables pass through. I used the dial lock when possible, and either tuned 
through the bag, or cheated a bit and opened the bag to get at the controls.

I imagine salt would be even more destructive than sand.

73,

Jim?? K8MR

[Elecraft] Crystal Filter Offset in 4.81, What does it mean?

[Mike K2MK]

I installed the 4.81 beta firmware and I am able to change the crystal filter
offset as described in the firmware notes. I can hear slight differences in
a CW signal between 0.1, 0.2, and 0.3 KHz. What I don't understand is what
does it mean. Previous to this release I would have assumed that the crystal
filter is centered on my chosen CW pitch suggesting a 0 KHz offset. If I
choose one of the 3 offsets am I now listening (and transmitting) slightly
off zero beat. Why would I want this? Wouldn't I also want a 4th choice of 0
KHz?

Explanations in layman's terms would be appreciated.

Mike K2MK

[Elecraft] K3 Beta Firmware 4.81

[Rodrigo]

Hello,

Just update mine s/n #6552 and for my surprise he lost power on the upper  
bands (18-28mhz). Instead of 100 watts he has 55 watts, more or less.

I revert the previous version ( 4.67) and the power back again.
Does anyone have the same issue ??

Re: [Elecraft] # 5607 first contact QRP!

[EricJ]

There are lots of "hangouts", but they are kind of limiting. They are 
handy when you are rockbound, or when you're collecting paper for QRP 
club awards. But why restrict yourself to a few channels when you have a 
rig that isn't restricted. That's where QRP signals belong--from one end 
of the band to another.


I rarely even mention that I'm QRP unless it comes up and I get a chance 
to convince someone to try it and give them a signal report. I don't 
force someone to try to ragchew when I'm 339, but if someone is 58 or 
better, I'm usually strong enough to get an acceptable signal report and 
have a casual QSO.


Try some of the weak signal digital modes too. When the objective is 
solid communication and not signal strength, they produce amazing 
results with VERY little power. You have a solid rig for running them, too.


Anyway, enjoy the rig. It will be good company on business trips.

Re: [Elecraft] Crystal Filter Offset in 4.81, What does it mean?

[Brian Alsop]

Guys,

I ran a sweep of the filter response with a 400 Hz filter at nominal 0.2 
and 03.


I have the plot but can't post here.

In short the left side of the filter response is moved to the right. 
The right side moves slightly inward as well.


The net effect is a narrowing of the filter -6db bandwidth and also a 
small shift in center frequency.


Here are the numbers:

BW (-6dB) =380 Hz, center 485 Hz @ 0.2
BW (-6db) =300 Hz, center 508 Hz @ 0.3

It appears if you do this, you might also have to adjust the filter 
offset to bring the center of the passband back to the nominal pitch value.

Can I just put a link between pins 5 & 8 of the aux plug and

Also as I understand it (surprisingly) the K3 does not have a

Re: [Elecraft] # 5607 first contact QRP!

[Dave]

I wasn't suggesting that they were the only places where people used QRP, 
but they are the places that you are likely to hear other QRP operators, so 
they aere good places to start.


Likewise, I usually tune up and down the band looking for whoever is around, 
QRP or not.  I also look out for CWOps members, as I'm also a member of that 
group, and they tend to wander about all over the bands. ;-)

It will if you choose a 300 Hz offset and Pitch less than 425 Hz for
the 250 Hz filter or a 300 Hz offset and pitch less than 400 Hz for
the 200 Hz filter.

One will see effects due to staggering the IF and DSP filters if the
selected Pitch is less than [Offset + (IF Filter width)/2].

Guys,

I ran a sweep of the filter response with a 400 Hz filter at nominal 0.2
and 03.

I have the plot but can't post here.

In short the left side of the filter response is moved to the right. The
right side moves slightly inward as well.

The net effect is a narrowing of the filter -6db bandwidth and also a
small shift in center frequency.

Here are the numbers:

BW (-6dB) =380 Hz, center 485 Hz @ 0.2
BW (-6db) =300 Hz, center 508 Hz @ 0.3

It appears if you do this, you might also have to adjust the filter
offset to bring the center of the passband back to the nominal pitch
value.

Re: [Elecraft] Crystal Filter Offset in 4.81, What does it mean?

[Lyle Johnson]

The "center of the passband to the nominal pitch value" only occurs at 
higher pitches and/or narrower passbands.


Think about the case where you have 1.5 kHz width selected and a pitch 
of 500 Hz.  You defintely do NOT want the center of the filter and the 
pitch to be equal,or you'd have terrible opposite sideband suppression.


The calculations done internally in the K3 to adjust the IF and AF 
passbands based on the settings of center frequency, width and pitch are 
fairly complex.


"Zero beat" has to do with frequencies, not filter responses, and 
changing the filter edge should have no practical effect on whether or 
not you are zero beat.  I say practical because the calculations done 
inside the radio coupled with finite resolution of the various 
oscillators may result in a 1 or 2 Hz difference, and someone is bound 
to measure this :-)


Finally, the new offsets apply to receive only. They have zero effect on 
how the radio is configured on transmit.

Re: [Elecraft] Crystal Filter Offset in 4.81, What does it mean?

[Wayne Burdick]

This just establishes the low-pitched rolloff by adjusting the filter position 
relative to zero-beat.

Setting it to 0.1 or 0.2 (the default) will have the least impact on the CW 
passband. 0.1 provides better low-end audio. 0.3 is for cases where you have 
such extreme signals that you need to lop off a bit more of the low end to 
eliminate any vestige of low-pitched opposite-sideband signals. For 99% of 
users, 0.1 or 0.2 will suffice.

Shifting the crystal filter center frequencies should not be necessary. I 
recommend just sticking with the offsets printed on the filters (0.00 for all 
8-pole filters).

[Elecraft] New KXPA100 beta-test firmware (rev 1.09) now available

[Wayne Burdick]

The latest KXPA100 firmware can be found at:

   http://www.elecraft.com/KXPA100/KXPA100_software.htm
 
Changes:
 
- ATU TUNE low-power threshold was adjusted so that ATU tuning doesn’t get 
stuck if the KX3's power output folds back (reduced due to SWR or high 
current). In prior versions, the KXAT100 would not start a full-search tune at 
less than 1.8 watts, and if power dipped below 1.5 watts during tune, tune 
would stop, waiting for more drive power. In the current version the KXAT100 
starts and continues full search tune at any detectable power over 250 mW. Its 
assumes that if the drive power is too low to compute SWR, then the SWR must be 
bad here, and we progress in the tune search algorithm. This is how the KAT3 
and KXAT3 ATUs work.
 
- Input power threshold was adjusted to reduce the incidents of faults during 
tuning.
 
- Band voltage tables for IC-703 and Yaesu FT-817 were updated. This was 
necessitated by hardware changes since initial measurements were made with an 
earlier prototype.

[Elecraft] New KPA500 beta-test firmware available (rev 1.37)

[Wayne Burdick]

The latest KPA500 firmware can be found at:

http://www.elecraft.com/KPA500/kpa500_software.htm

NOTE: Please also install the latest KAT500 firmware, if applicable. This is 
the subject of a subsequent email.

Changes:  

1. Attenuator fault deferred to allow KAT500 to interrupt amp key line

During normal operation, an in-band frequency excursion or band change might 
result in a temporary high reflected power condition. The KAT500 can interrupt 
the amplifier key line within a few tens of milliseconds to adjust its settings 
accordingly, but during that period the KPA500 used to flash a red FAULT LED 
indicating a “soft” attenuator fault. This change defers the illumination of 
the FAULT LED for a short period (about 1/4 second). If the reflected power 
continues to be high long enough, then the FAULT LED is illuminated as before. 
There’s no difference in the way the amp protects itself; it just doesn’t light 
red LEDs in the early part of this cycle. With this change (and corresponding 
KAT500 firmware changes), QSY and band switching with the KAT500/KPA500 should 
not blink the KPA500 fault LED.

2. New fan speed query command (for remote control applications).

Re: [Elecraft] re "No. 5607 first contact QRP"

[Tony Castellano]

It may seem that I'm bragging, but I can't help letting this thread pass 
without a comment in the hopes that I can convice other

hams that they don't need any more that 5 Watts.
First, let me say that QRP and QRPp works. All it takes is a little 
determination, patience and of course a good rig like a KX3
or K2. I never call CQ and I never sign /QRP. I even get through pileups, 
and let me add that I'm not an exceptional operator.

To date, I have worked 188 QRP CW countries.
Also, I have worked 74 countries with my KX3 running 100 milliWatts (0.1 
Watts CW QRPp). My best being New Zealand

from my QTH in New York State for 88,539 miles per Watt
My antenna, by the way is a 135 foot OCF dipole about 40 feet above the

Same feeling here.  I run a K3/KPA500 at the home QTH (in Colo.) but built 
a KX3 (s/n 5411) to take with me for the few weeks when I am working away 
from home (in NY).  With the simplest low dipole it's a kick to work the 
world with 5 watts - and even more so to sneak through a pile-up.  As a 
new QRPer myself I was attracted by the "KMPW" challenge (though I can't 
recall who's sponsoring it) - "thousand miles per watt."  I am at a little 
over 0.9 KMPW with the KX3 so far; I heard that someone did a 9,000 mile 
QSO with 500 mw, for 18KMPW.

[Elecraft] re "No. 5607 first contact QRP"

[Dauer, Edward]

Same feeling here.  I run a K3/KPA500 at the home QTH (in Colo.) but built a 
KX3 (s/n 5411) to take with me for the few weeks when I am working away from 
home (in NY).  With the simplest low dipole it's a kick to work the world with 
5 watts - and even more so to sneak through a pile-up.  As a new QRPer myself I 
was attracted by the "KMPW" challenge (though I can't recall who's sponsoring 
it) - "thousand miles per watt."  I am at a little over 0.9 KMPW with the KX3 
so far; I heard that someone did a 9,000 mile QSO with 500 mw, for 18KMPW.

[Elecraft] OT: PIC programming hardware and software information

[Lee Buller]

I know there are a lot of you people who are into PIC programming and I am 
looking at doing so.

After reading for many hours in the Internet, I have become awash in PIC 
programming hardware and software.  I need someone who is knowledgeable to 
recommend something to me to get into this field.  Requirements are:

I would like to build it myself (DIY)
USB or RS232
No Parallel
I would like to program 18F stuff but others would be good too.
Software?

Thanks.  You can email be direct if you would like since this is a little off 
topic here.

Re: [Elecraft] # 5607 first contact QRP!

[Phil Hystad]

I think a good way to "test" whether QRP actually works or not is to establish
a contact with someone say using 100 watts and get a signal report (RST) and
then drop your power output to 1 watt or maybe 2 or 5 watts and then ask for
a signal report again.  I am always surprised at how good the reports are after
dropping power.  This is the main thing that got me into QRP in the first place.
Until then, I never thought that you could make such good contacts but then 
again
I was a bit naive on the topic too.  My first QRP rig was the Norcal 40A and my
favorite was the KX1 until the KX3 came along but I still like the KX1 and even
use my Norcal 40A from time to time.

Re: [Elecraft] [K2] K2-100 Test and Alignment Issues

[William Moore]

Don,

Thanks you for this tip, and yes, I now realize my windings on T4 are not
exactly as shown in the manual. However this realization raises a broader
concern. 

Here is what happened. I wound my toriods using a winding tip I'm sure I
picked up on the Elecraft list some time ago. To wind the toriods, I put the
wire(s) to be wound on the core through the toroid core half way, pull up
the two ends at a 12 o'clock point on the toroid core then wind one lead
counter clockwise to about 7 o'clock and the other lead clockwise to about 5
o'clock. I now realize that this will result in the toroid being would in
reverse to probably the standard winding practice of starting only one long
lead at 7 o'clock on the toroid core and then winding all the required turns
on the core around to about 5 o'clock.

I have now pulled, T4 and rewound it exactly as shown in the manual. I am
ready to reinstall it but before I do, here is the broader concern. I have
also reverse wound T3 as well as each and every other toroid core on the
KPA-100! Do you think this will create problems such that I will have to
remove, rewind and reinstall all the toriods, just certain toriods or is it
just T4 that is an issue? What makes me wonder is that I built my entire K2
and the KBS2 using the "12 o'clock high two-lead core winding system" and
the K2 works just fine for me but then I can't verify if the my K2 is really
performing exactly to specifications because I don't have test facilities to
do so.

I would really appreciate your comments on this issue before reassembling
the circuit board back onto the heatsink in case I need to make other
changes to the toriods.

Thank you.

Bill, VE2WMA

Subject: Re: [Elecraft] [K2] K2-100 Test and Alignment Issues

Bill,

Regarding T4, there is one other possibility that I did not mention before.
If the direction of the windings is not as shown in the manual, it will work
"backwards" which may be what you are observing.

As for the minimum voltage of 1.4 volts, that is WAY too high.  The bridge
should null to less than 14 millivolts with 15 or 20 watts flowing through
it.

You could do a sanity check on it by attempting to null the bridge by
monitoring the DC voltage at U5 pin 3 rather than U5 pin 1.  The voltage on
U5 pin 1 should be the same as at pin 3 if U5 is working OK.
If you still have a high voltage at U5 pin 3, then try doing the balance
(nulling) while monitoring U5 pin 5.  If you can obtain a null at U5 pin 5,
then for certain T4 is wound in the wrong direction.

[Elecraft] OT: Mini-Manuals for Yaesu Handhelds

[Brian F. Wruble]

Sorry for this:  I used to have miniature "cheat sheet" manuals for my
Yaesu VX-5R and VX-6R HTs.  I am NOT referring to "Nifty".  These were more
to my liking.  They were yellow, multipage booklets that fit in a shirt
pocket.  I think a VE ham published them.

Can anyone guide me to the source?  I am striking out with Google.

Re: [Elecraft] K3 and the LDG AT 600 Pro II

[Jim Bennett]

Hi Rob,

Up until a few months ago I had been using my K3, going into an Ameritron 
AL-811 amp, through the LDG AT-600 ProII, and then to an external 4:1 balun, 
110 feet of 450 ohm ladder line, and an 88 foot long doublet. I also had the 
M-600 analog meter connected to the AT-600 ProII.

Nothing special was needed - I ran RG-8X coax from the K3 to the amp, from the 
amp to the '600, and from the '600 a couple of feet to the 4:1 balun.

The AT-600 was able to tune just about anything that the internal tuner in the 
K3 did, although not always as low of an SRW - but pretty darn close.

Jim / W6JHB

p.s. - I sold the tuner, meter, and amp to a local buddy and replaced them with 
the KAT500 and KPA500 for my birthday in November.

Re: [Elecraft] SPOT for SSB feature request

[Bill Frantz]

Indeed Don, that change has helped a lot. Now I can tune the 
vast majority of SSB signals on 160, 80, 20, 15, and 10 meters 
while in coarse mode.


I have noticed that some of my tuning problems seem to be slow 
response from the K3 - P3 - SVGA link. I usually tune SSB 
looking at the waterfall on the SVGA screen. There is a bit of 
lag updating the vertical stripe showing bandwidth and the tuned 
frequency at the top middle of the screen. My hand gets ahead of 
the screen. I think this problem would go away if I looked at 
the K3 display, but then I can't see where the signal is.

Re: [Elecraft] # 5607 first contact QRP!

Sorry to point out the obvious, but that could be said of any power 
level. And add band conditions at any particular point in time. There's 
nothing magic about 5 watts out and there's no more magic at 100 watts 
out. 100 watts will get out some times when 5 watts won't, but 5 watts 
(or far less) will get out a lot more times than most hams realize. I 
think that's all most QRPers are saying.

Re: [Elecraft] # 5607 first contact QRP!

[Vic Rosenthal K2VCO]

Actually, many QRPers seem to be saying that it's /easy/ to work the 
world with 5 watts and a crummy antenna, and it's sinful to use more 
power, or, God forbid, a beam.


It is /hard/ to work DX with 5 watts and a low dipole (or worse, a 
Buddipole or similar antenna). This can be very frustrating to new hams 
who have yet to develop the operating skills that make this possible.


QRP is great fun, but the 13 dB between 5 and 100 watts is very 
significant. And the difference between a short, loaded vertical and a 
beam can be even more significant.

Re: [Elecraft] KXPA100 shipping status page update (correction)

[Eric Swartz - WA6HHQ, Elecraft]

[typos corrected!]

1-5 days after we notify you its about ready to ship.

If we have not contacted you about final billing and shipment and you ordered 
before or on January 1st (PST - CA time), please email sa...@elecraft.com or 
call our sales group at 831-763-4211 and they will get everything going for you. 
We have found that some customer's anti-spam filters are catching our email, or 
we have an incorrect ro old email for them, causing our notification emails to 
be missed.


Also, we have made an additional correction to the shipping status page - NEW 
orders received will now ship in 1-2 weeks after order.


We are rapidly catching up with the backlog and we should be down to 1 week or 
less shortly on new orders.

[Elecraft] Vedr: [KX2]

[Martin Storli - LA8OKA]

Good idea!  But I want 80 m and 10 m included as well!
A kit in the tradition of the K1, K2 and KX1, a KX1 form faktor with built in 
antenna tuner, but with SSB would be a welcome adition to the Elecraft line!

Hello Aptos Dudes,

SOTA is exploding in popularity and your product line started with a radio

How about a KX2, through hole, 7 to 24 MHz CW / SSB 20 W. SOTA radio?

I love my KX3 on summits.

Good Wishes,

[Elecraft] DSP and the KX3

[Phil Hystad]

For you KX3 signal processing experts and the algorithms implemented for the 
KX3?

Is there any work to clean up an actual SSB signal to make it more intelligible 
in cases of various phase changes or interference via reflections (ionosphere). 
 I mean, a slightly warbled signal cleaned up to reduce or eliminate that kind 
of distortion?

I am not even sure if or how this can be done as my experience in signal 
processing is certainly not up to that level but it seems that it may be 
possible.

No, this is not because I am having a problem with my KX3, it is a question 
asked by a friend of mine so I am relaying it here.

73, phil, K7PEH

Re: [Elecraft] [KX2]

[Wayne Burdick]

Hi Glen,

I don't think we'd design a different portable SSB rig just to make it a 
through-hole-components kit. We'd either have to make it a lot larger than the 
KX3 or greatly reduce the number features and level of performance. We did this 
calculation a few years ago and the KX3 is the right answer :)

Re: [Elecraft] XVTR IF BAND CAN NOW BE 10 OR 18 MHZ

[Wayne Burdick]

There's no particular benefit to an 18-MHz I.F. But 10 MHz can be useful for 
VLF/LF transverters (e.g., 500 kHz) because very high-stability 10-MHz 
oscillators (OCO's, or oven-controlled oscillators, etc.) are available at low 
cost for use as the mixer injection oscillator. This combined with the K3's 
excellent stability can allow the use of extremely narrowband modes that 
require very low drift.

Re: [Elecraft] K3 and the LDG AT 600 Pro II

Coax from the K3 to the LDG tuner, coax from the tuner ANT 1 output to 
the balun (running a doublet). 12v to the tuner. Change freq on the K3, 
TUNE on the K3, and let the LDG do its job. No control cables or 
anything special needed.

Re: [Elecraft] DSP and the KX3

Hi Phil,

The KX3 (and K3) both provide several ways to make speech signals more 
intelligible in the face of noise or reflections, including NR (stochastic 
noise reduction), NB (impulse blanking), and passband shift/width adjustment. 
I'm not sure that compensation for multipath distortion is possible or even 
desirable, but it's an interesting question.

Re: [Elecraft] DSP and the KX3

[Phil Hystad]

Wayne,

Thanks for the quick reply.  My friend and I were discussing ways of doing this 
(that is, sending/receiving clear voice with DSP helps) and then I decided that 
it has been done.  Well, not by the K3 because it does not digitize the actual 
signal being sent but I was thinking of D-Star and its use with repeaters.  I 
wonder how wide that digital signal is, maybe you know.  D-Star on HF might be 
too wide.

Re: [Elecraft] # 5607 first contact QRP!

[Stephen Roberts]

You're right of course. It takes some time to get comfortable with QRP and its 
limitations, and you're right, that it can be a source of frustration for many 
new hams.  Your are also absolutely right that when you ad a crappy antenna to 
the mix, it can be very frustrating indeed. But that's the fun of learning and 
discovering all that is ham radio. 

I started with an OHR 100a 40m rig and a homebrew magloop antenna set up on a 
tripod in my kitchen. I was happy as a clam and simply didn't know what I was 
missing and found plenty of QSO's to keep me occupied while I figured out what 
it was all about. I had other ham friends telling me that I was setting myself 
up for disappointment if I didn't get at least a 100W radio, but I stuck it out 
and never felt that I was missing much. I still feel that way, and I'm still 
having fun.

Re: [Elecraft] XVTR IF BAND CAN NOW BE 10 OR 18 MHZ

[Edward R Cole]

Just to expand a big on what Wayne states:

Operation on the upcoming (but not yet established by the FCC) new 
600 meter ham band on 472-479 KHz, K3 use is enhanced by this upgrade 
in the firmware.  It allows operating the K3 on 10.472-10.479 MHz as 
the IF input to a transverter which can use a super-stable OCXO or 
GPS disciplined oscillator as the 10 MHz LO.  Since there will only 
be 7-Hz spectrum in the whole ham band only narrow band modes will be 
allowed.  Stations will need to hold +/- 1-Hz in frequency stability 
and accuracy to avoid interfering with each other.


I use a surplus OCXO (Oven Controlled Xtal Oscillator) that I bought 
on e-bay for $45.  This holds my K3 to 0.01ppm by use of the EXREF 
and TCXO-3 options.  On 10-MHz band this results in under 1-Hz 
drift.  Using a transverter that has drift considerably below 1-Hz 
permits me to use my K3/10 (w/ KVX3) on this new band.


I am in early design process to make such a transverter with 25w 
output and utilizing a 10-MHz OCXO for LO.  At this time I'm 
considering offering it as a kit.  Only 1mw RF level is needed by the 
transverter for IF drive.  I expect this is six months off in 
realizing.  It would also be nice if the KX3 was able to work at 
10.472-10.500 MHz.

Re: [Elecraft] XVTR IF BAND CAN NOW BE 10 OR 18 MHZ

[Wayne Burdick]

Ed,

Your transverter idea sounds like a nice addition to the K3. (Such a 
transverter could be also used with the KX3. But due to size constraints, of 
course, the KX3 uses a different synthesizer technology that can't provide 1-Hz 
stability.)

Re: [Elecraft] # 5607 first contact QRP!

[Don Wilhelm]

Yes, there are many QRPer's who also frown on beams and other efficient 
antennas, but I disagree with that philosophy.  Why 'shoot yourself in 
the foot' with a compromise antenna unless your physical conditions 
dictate that compromise as a necessity (HOA restrictions, portable 
operation, etc.)


If you operate with 5 watts and an antenna with 3 dB gain, you will have 
the equivalent of a 10 watt signal, and if you can achieve an antenna 
with 10 dB gain, you have the equivalent of a 50 watt signal into a 
dipole. (yes, I know those are extremes).


Much of the QRP work with compromise antennas is a problem on the 
receive side.  If you cannot hear them, you cannot work them.  So why 
handicap yourself with inefficient antennas.  Check QRPARCI - you will 
find no credits or deductions in their contests for antenna 
inefficiency.  Use the best antenna that you have for the task.


QRP operation will increase your operating skills - listen, listen and 
listen, figure out the other stations habits, operate split if 
necessary, and call when you think your signal will be heard.

Don W3FPR

You're right of course. It takes some time to get comfortable with QRP and its

the mix, it can be very frustrating indeed. But that's the fun of learning and 
discovering all that is ham radio.

I started with an OHR 100a 40m rig and a homebrew magloop antenna set up on a 
tripod in my kitchen. I was happy as a clam and simply didn't know what I was 
missing and found plenty of QSO's to keep me occupied while I figured out what 
it was all about. I had other ham friends telling me that I was setting myself 
up for disappointment if I didn't get at least a 100W radio, but I stuck it out 
and never felt that I was missing much. I still feel that way, and I'm still 
having fun.

[Elecraft] CW memory problem

[Carl Yaffey]

I used the K3 utility to set all 4 CW memories. M1 has my call. I’ve been using 
that one extensively lately. Today, after an hour of calling W1AW/KH6, suddenly 
pressing M1 gives me this:
Main display: uC 04.67
VFO B display: FW REV5

The other 3 memories still work fine. I went into the utility and found my call 
still in M1. I re entered it and saved.
Problem is still there. I need a clue, please.

Re: [Elecraft] DSP and the KX3

[Walter Underwood]

It might be possible to decompose speech into a constellation of formants and 
filter out frequency and time components that didn't match human speech 
patterns, a bit like a Viterbi decoder for speech. You'd have to be careful not 
to overfit the training vocabulary and to allow for different speakers, 
languages, etc. I expect the processing would add a lot of delay. 

Get started in digital voice on HF with the information and software at 
http://freedv.org/ The current favorite mode is 1.25 KHz wide.

Don't know your K3 S/N, but I'm having some problems with S/N 642 doing 
"similar" things.  Pressing switches sometimes does nothing [common with 
TX TEST], and occasionally, does something I really wasn't expecting at 
all, unrelated to what was supposed to happen.


I've gotten the impression it may be related to the plating on the edge 
connectors between the RF and FP boards.  Given my low S/N, I am pretty 
sure I don't have the gold plated ones and may need to get the mod kit. 
 I'll probably send it into the Elecraft shop if that's really a likely 
cause.


I did anchor my K3 to the shelf with small squares of auto moulding tape 
under the feet so I can push the switches more positively without moving 
the radio.  That has helped some.

Re: [Elecraft] DSP and the KX3

[george fritkin]

What is needed is complete digital voice transmission.  Of course you would 
lose the personal touch on SSB but one could make weak signal operation 
somewhat better.  With encryption keys, you could talk to your buddies in 
complete confidence.  Gee what would the guys on 75 and 20 do if they lost 
their audience??
 
Perhaps the new K? could incorporate that function

There are two banks of 4 memories, and you switch between them by a HOLD of

Re: [Elecraft] CW memory problem

[Dick Dievendorff]

Maybe somehow M1 has been assigned as a program function key.  Try tapping
REC and then tap M1 to reassign M1 to its memory function.

Re: [Elecraft] CW memory problem

[Mike K2MK]

Hi Carl,

This has come up before on the reflector. It was caused accidentally as
follows. Somebody held the MENU button such that the K3 displayed uC 04.67
and FW REV5. Next they pressed the M1 button. That's all it takes to assign
a M key to a configuration function.

73,
Mike K2MK

Re: [Elecraft] CW memory problem

[Sam Morgan]

I've shot myself in the foot like this before
if you are in the CONFIG menu
and you hit the M1 button
then what ever CONFIG entity that you were looking at
is placed in that M1 button

if I remember correctly..
to get out of it
tap REC
then tap M1
then use ur key to send what ever you wanted to enter into CW M1
the hit REC or M1 and it will save the cw entry

hope my rememberer got that right

You must have checked few version and then pressed M1 and thus set M1 to check

Re: [Elecraft] # 5607 first contact QRP!

[EricJ]

And that's an important point, Don. A poor antenna hooked to a 5 watt 
rig is no different than a poor antenna hooked to a 100 watt rig...in 
receive. Power sometimes gives you an advantage on transmit under 
marginal conditions, but it does nothing on receive as you mention. Then 
you run into the classic "can't work 'em if you can't hear them" barrier 
no matter how much power you run.


I have three boatanchors (2NT, DX40 and Ranger) and they run around 
50-65 watts INPUT. That's what 90% of hams ran in the 50s and 60s and 
that's only an S unit or so better than my K1 or K2/10.


Anyway, I said what I wanted to say which is most of the argument 
applies to any power level, not just QRP. Part 97 says run no more power 
than necessary. QRP meets that criteria for the majority of operating.

yourself in the foot' with a compromise antenna unless your physical 
conditions dictate that compromise as a necessity (HOA restrictions, 
portable operation, etc.)


If you operate with 5 watts and an antenna with 3 dB gain, you will 
have the equivalent of a 10 watt signal, and if you can achieve an 
antenna with 10 dB gain, you have the equivalent of a 50 watt signal 
into a dipole. (yes, I know those are extremes).


Much of the QRP work with compromise antennas is a problem on the 
receive side.  If you cannot hear them, you cannot work them.  So why 
handicap yourself with inefficient antennas.  Check QRPARCI - you will 
find no credits or deductions in their contests for antenna 
inefficiency.  Use the best antenna that you have for the task.


QRP operation will increase your operating skills - listen, listen and 
listen, figure out the other stations habits, operate split if 
necessary, and call when you think your signal will be heard.

indeed. But that's the fun of learning and discovering all that is 
ham radio.


I started with an OHR 100a 40m rig and a homebrew magloop antenna set 
up on a tripod in my kitchen. I was happy as a clam and simply didn't 
know what I was missing and found plenty of QSO's to keep me occupied 
while I figured out what it was all about. I had other ham friends 
telling me that I was setting myself up for disappointment if I 
didn't get at least a 100W radio, but I stuck it out and never felt 
that I was missing much. I still feel that way, and I'm still having 
fun.

[Elecraft] Fraud

[Bill Ross]

Just a heads up to all on the list, someone is posing as me, William H. Ross at 
k6mg...@aol.com and listing a K3/P3 station with all equipment for $2950. 
I don’t have a P3, but do have a K3 which is not for sale now, around Christmas 
time, I did post an ad on QRZ listing my K3 for sale, and per QRZ’s 
requirements, sent a picture of the K3 with a QSL card in the picture to 
authenticate it which this person copied and posted on QTH with the phony ad. I 
have received emails and phone calls from several hams wanting to inquire if 
the ad was on the up and up, which of course, it wasn’t. 
So if anyone see’s this ad or hears about anyone wanting to buy this equipment, 
please warn them that the ad is a fraud.

Tnx and 73

Bill, k6mgo

Re: [Elecraft] Fraud

[Mark Stennett]

Nigerian scammer. These clowns have discovered ham radio, unfortunately.

Be very cautious on the Internet. Trust no one and thoroughly vet your seller 
before sending money.

I am seeing more and more of this stuff on eham. I manage the classifieds there.

I had a recent case where a ham had his qrz account compromised because of an 
email that linked to a fake qrz page where he then logged in. What made this 
incident different from the tens of others I deal with on a monthly basis was 
that he apparently used the same password at the FCC. The scammer changed his 
address with the FCC to one used by a third party to receive a cashiers check. 
Scammer posted an ad on eham using same password and scammed a guy out of a 
grand for a non existent amplifier.

Victim was asked to make check out to a third party name.

The Internet is a nasty sewer full of scammers.

[Elecraft] Re CW memory problem - SOLVED

[Carl Yaffey]

Thanks for all the responses. It seems I reprogrammed M1 inadvertently. 
Probably by pressing something (like MENU) and pressing M1. I used REC and 
keyed in my call to M1 using the paddle and all is well. Funny though. I tried 
to redo M1 via the utility and that didn’t work.
Thanks again and 73,

Re: [Elecraft] K3 and the LDG AT 600 Pro II

[Robert Biamonte]

Of course I just thought of the phraseology, I am looking for a control cable 
like the ones made for Yaseu and Kenwood. This cable would reduce the K3 power 
to Tune level and return the power to normal when the Tune button is released 
on the K3. Operating like the built in antenna tuner on the K3.

[Elecraft] Elecraft KFL3A-6K vs Inrad 710

I've got the Inrad 710 6000 Hz in the main Rx, its center frequency

Any issues my ears will be able to tell if I put a 6000 Hz KFL3A-6K

Re: [Elecraft] K3 and the LDG AT 600 Pro II

[Don Wilhelm]

Rob,

Take a look at the manual for CONFIG: TUN PWR - that will set the power 
level used for a TUNE.
If set to NOR, it will follow the power knob, but otherwise will TUNE at 
the power set in the menu.


ATU TUN is different than TUNE.

Re: [Elecraft] [KX2]

[Glen Torr]

Hi Wayne and all,

Thanks for the explanation which makes a lot of sense.

I wonder if the KX2 could be a CW no solder SOTA rig in a KX1 form factor.

Here in VK SSB is much more popular than CW for SOTA and this is a subject
of discussion on the VK SOTA group.

I am determined to do CW and would love an Elecraft SOTA rig.

That said thanks a bunch for the KX3, I can scarcely believe the technology
in this amazing radio.

Thanks for the pleasure you have given me.

Cheers,

Glen VK1FB
