Re: [Elecraft] Stream and Vista for MFSK

[Tom Price]

Thanks to you all. I now am barking up the right tree, or at least I am in
the right forest. I did go in and edit the settings and edited rig.xml.
Thank goodness I have some experience in web pages and HTML it all made
sense to me (scary). Thanks Julian the help and directions are greatly
appreciated. I am going to try to do this all in my truck with a laptop
someday, (not driving of course). I did do some CW mobile several years ago
with a HW-7 and a leg key with a stick shift! I think it is like a banjo
player.

Re: [Elecraft] [K3] Poor man's beverage and diversity

[David Cutter]

Sounds like this one:
http://users.erols.com/k3mt/graswire/graswire.htm



A few minutes before the start of the ARRL 160m contest I decided to try 
something I'd heard about. I took about 180 feet (55m) of wire and laid it 
on the ground from my shack, across the backyard, around the back of my 
garage and all the way down the edge of the driveway.


It turned out to be an excellent 160m receiving antenna! I expected that 
signals would be very weak, but they were almost as strong as on the 
transmitting antenna. My antenna analyzer showed an SWR of about 2.5:1. 
And, most important, the s/n ratio was much, much better.


I connected it to the AUX input of the sub-receiver and activated 
diversity mode with a (very) long hold of the SUB button. I went to the 
CONFIG menu and set for SUB AF = BALANCE so that the sub's AF gain control 
would act as a balance control between the two receivers.


This works great! I can hear signals get stronger in one ear when they QSB 
in the other. And for signals which come in better on one antenna than the 
other, I just turn the balance control.


Even if you don't have a subreceiver, you should try the "poor man's 
beverage" (no, I don't mean wine in cardboard boxes) receiving antenna. 
Although the directivity is sort of arbitrary, the noise is way down 
compared to a vertical.


The contest will still be going tonight. Try it, there is no antenna that 
is easier to install!

[Elecraft] UK Elecraft net report for Sunday 7th December

[Dave G4AON]

We enjoyed a relatively clear frequency but had to QSY at one stage,
probably losing Stewart G3RXQ in the process. David MM0XDG's newly
completed K3 (some 30 minutes prior to joining us) sounded very good.

Topics included: N1MM and other logging programs, why bother with
modifications at all?, factory fitted AF mod vs. field fitted version
(new K3 has the RFC on top of the board), connecting a Linear Amp UK
amplifier to a K3 (make sure the TX delay is long enough to cope with
slow relays), problems with intermittent operation caused by cutting the
TCXO leads too short (instructions wrong?) and locating buried antenna
cable with divining rods.

Stations were:

G4LWA, Alan
G0MJW, Mike
MM0XDG, David
GM0ELP, Doug
G0VGS, Ian
G3RXQ, Stewart
GM3SEK, Ian
EI6IZ, Brendan
M1KAZ, Andrew

lies in convincing the poor neighbor that while you are  the cause of the

[Elecraft] Memory Chaining Anomoly

[k4pi]

When trying to use the CW Memory Chaining function I ran into an anomoly in 
that it depends on when you "tap" the memory M1-M4 button during the sending 
of the message.  Example..  If the memory contains my call K4PI..  I hit the 
button during the sending of the 4 it comes out on the air as KSPI or KIPI. 
If it hit the button during the P it comes out K4AI or K4EI.  The one place 
it does work correctly is if I tap it during the K.  I have monitored on the 
air to confirm that it is not having a problem just in the sidetone.  Anyone 
else come across this?  73 Mike K4PI

[Elecraft] RX EQ comments

[K2MK]

I set up the RX EQ for a boost at 400 and 800Hz for CW. I also lowered the 
others which had the effect of reducing noise. The results were good. I then 
listened to some SSB and realized that the equalized settings were the same 
as I had set for CW. I couldn't find a way to have one group for CW and 
another for SSB. It seems like there should be unique settings for the 
different modes.

[Elecraft] Dec. 13th PBMME

[Ron Polityka]

Hello,

Now that the cold weather is taking hold on most of the country, you will 
find a bunch of QRP Operators called the Polar Bears wandering out in the 
cold on December 13th for the PBMME.


For more information, please check out www.n3epa.org and click on the Polar 
Bear QRP Club link. Please check back on Dec. 12th for any update of Polar 
Bears going out to operate. There will be a bunch of guys out there with 
their Elecraft Rigs. I will be out there with my K1 - SN 01011.



I need only 13 more QSO's from the Appalachian Trail to have a total of 
1,000 QSO's from the AT since March 2000.

Re: [Elecraft] HPS-1a Gamma Hybrid,Communications Power Supply

[Paul Christensen]

It works at 100W SSB with 10-20dB compression.
For CW at 20WPM you need to go down to 70W or so.


I've been testing the Gamma supply with my K3 on CW.   It works very well at 
95W down to about 15 WPM.  I rarely send below 20WPM and at that speed, the 
rig's full 100W can be expected.  Even with this limitation, it's a 
remarkable device, given its size.


I'm a bit leery of the over-voltage protection circuits built into these 
small supplies.  I added a Vishay 1.5KE15A 15-volt transient suppressor, 
reverse-based across the DC output (Mouser P/N 625-1.5KE15A).  The diode is 
in parallel with the DC output terminals but a series fuse is inserted just 
ahead of the diode.  This is essentially a zener crowbar device that upon 
reaching 15 VDC will conduct and blow the DC fuse before any damage is done 
to the rig (or one hopes!)


My only nit with the supply is that the AC line cord is hard-wired into the 
unit.  An IEC receptacle would have been a nice addition. But in all 
fairness to the designer, there's almost zero room inside the enclosure for 
the receptacle.  One alternative is to cut the line cord ~ 6-inches from the 
cabinet and add an IEC pig-tail.  This offers the benefit of being able to 
use an IEC RFI/EMI filter as part of a disconnecting pig-tail assembly.

Re: [Elecraft] [K3] Poor man's beverage and diversity

So, if you made it 19% longer with some zig-zags, it would be resonant in 
the middle of the cw band and no need for matching, just connect to coax.  I 
imagine it's fairly broad band being so close to the earth.

If the 2.7Khz sub filter is enabled for SSB and CW, are you getting sub

Re: [Elecraft] HPS-1a Gamma Hybrid,Communications Power Supply

[David Cutter]

Paul

I'm always a little wary of this scheme since using it myself a while ago 
and not getting the results I expected.  I would call it a limiter not a 
crowbar.


I'm guessing these supplies have a relatively high (compared to conventional 
linear regulator) output resistance and when I've done this with other 
supplies it doesn't actually blow the fuse.  I'm sure it would still protect 
your rig, but simply act as a peak limiter using the fuse and holder and 
output resistance to pull the output below the clamping level.  Don't know 
what fuse you are using: say it's an ordinary "fast" blow 20A, then you will 
need >40A for 30s to blow it by which time the transient has long gone.  The 
clamping voltage also depends on the current drawn and could be as high as 
21.2V according to the spec. I would have to draw a load line to find out 
how that would perform with the supply but that would be only static 
conditions.

[Elecraft] Re: Poor man's beverage, Ground Cooperative Antennas

[Niel Skousen]

something that will enhance such an antenna is to raise a portion of  
the wire off the ground 2 or 3 feet (use an arrow, staple to a wood  
fence, or field expedient bush etc), leaving the last 25% or so laying  
on the ground.   the elevated portion will have substantially improved  
radiation performance and will have a faster velocity, but the 25%  
left on the ground will act as the beverage termination...


If you do this with the long leg of K3MT's Grasswire Windom (eg 70 ft  
elevated,  26 ft on ground) you'll get gain in the direction of the  
long leg, and a reasonable FB ration too...The back leg (short  
side) can be cut down to about 30 ft with out too much impact on the  
swr at 40m and above.


Another couple benefits are:  the vertical lobes which a significant  
to an elevated beverage are dramatically smoothed, and the antennas  
may be array'ed at relatively close spacing.   Two of the K3MT  
Grasswire Windoms can be laid out in parallel about 25 ft apart, and  
fed in phase ( simple power splitter and equal length coax is good  
enough)  as a two element broad band array.  Such an array will  
approach -3 dbi (~20 TOA) at 15m.


Some additional info can be found by googling " Eyring Low Profile  
antenna "


Have fun

will also want to do the DVR3 before you re-mount the Front Panel.


I have later serial numbers so I don't know about the 3 mod's but given 
the KRX3 covers the main board up I would sure think you need to do them 
before or as part of the KRX3 install. You have to take the front panel 
and sides off and the front part of the bottom off to install the KRX3.


There is no question that people down the road who buy everything will 
have a lot less steps because now doing the various additions as they 
arrive involve some tearing apart what you already have done.  However 
this is a small price to pay as we have had the enjoyment of using the 
best radio available for a lot more months and a big head start learning 
how to operate it.  There is a lot to learn as the radio can do so much. 
 Becoming more familiar with the radio in the long run is a good thing. 
 Given the type of construction and if Elecraft stays in business and 
with firmware and other updates being possible this radio should be able 
to be top of the line for many years to come.

That has been my theory too.  But it begs one further question.

I have the KRX3 second receiver, the ALC mod, Ant Shunt Switch Mod, CW Rise
Time Mod, the Hardware AGC Mod all sitting here waiting to be installed and
my DVR3 is on its way to me.  Can you or anyone who has completed these
additions recommend a specific order in which to perform their installation
that might minimize any unforeseen headaches?

Thanks.

[Elecraft] Units

[Mike Harris]

G'day,

| My 180' wire was resonant at about 2.2 mHz, where the SWR was around 
1.4:1. Since signals

Spectacularly slow velocity of propagation there.

Here we are, custodians of a technical hobby, one that we have to achieve 
qualification in for licensing and we can't get our units right.  MHz,

Re: [Elecraft] HPS-1a Gamma Hybrid,Communications Power Supply

[Paul Christensen]

output resistance to pull the output below the clamping level.  Don't know 
what fuse you are using: say it's an ordinary "fast" blow 20A, then you 
will need >40A for 30s to blow it by which time the transient has long 
gone.  The clamping voltage also depends on the current drawn and could be 
as high as 21.2V according to the spec. I would have to draw a load line 
to find out how that would perform with the supply but that would be only 
static conditions.


Agree with all your statements.   I tested the circuit ahead of time with a 
variable switching supply and a 25A fast-acting fuse (a value I am currently 
using with the K3).  At about 15.5V the diode clamped, the fuse blew and the 
circuit opened up as intended.  The diode remained good after that fault 
event.  Now, how fast did the fuse blow?  According to the info I've 
gathered from the Littelfuse and Bussman 3AG fuse datasheets, not fast 
enough to ensure 100% protection.   Also agree that some switching designs 
will limit current ahead of the zener device and that may preclude the fuse 
blowing.  I don't particularly care as I still want that fuse there for 
safety purposes.  Again, all this may be trivial in the grand scheme of 
things if the Gamma OVP design actually works.


But consider this: as long as the diode is clamping, even if we're waiting 
for the fuse to blow or the current of the supply to self-limit, the diode 
should still be performing a reasonably fast protection function.  OTOH, if 
the diode fails while we're waiting for the fuse to open or the circuit to 
self-limit, all bets are off on the usefulness of the diode.


A fast-acting circuit breaker may be better -- or not.  I need to research 
the available types of CBs a bit more, including the Airpax types.


Paul, W9AC

[Elecraft] Musings on Noise Reduction

[John Graf]

I ran a single-op QRP effort in the ARRL 160M contest this weekend.  I ran
about half the time with my K2, and the other half with my K3 @ 5 watts.  It
was interesting to compare the two rigs.

I did not run any laboratory tests, so this clearly falls into the category
of opinion.  But the K2 DSP noise reduction is far superior to the K3's, at
least on 160M.

I played with the settings on the K3's NR throughout the contest, but it
always appears to me that engaging NR reduces the signal level by a good 10
dB (or more) no matter what you do.  By setting it to F1-1, there is a
reasonable tradeoff between noise reduction and signal strength, but just
about any other setting seems to drop the signals into the mud,

I also did some reading (during daylight hours) and found a good article on
K3 NR at http://www.zerobeat.net/mediawiki/index.php/K3_DSP  The gist of
that article is that in order to get the most benefit from the NR system,
you need to keep your bandwidth set rather wide.  There may be some truth to
that. but it is not a strategy that works well during a contest.

The K2, on the other hand, does not significantly reduce signal level when
NR is engaged.  It also does a great job of dropping the noise level by
several S-units.  There is some signal distortion, but it is not
objectionable.  The best part is that you can reduce the bandwidth using the
narrower CW filters, and the noise reduction is not affected.

The K3 is a superior rig in most aspects and is still my choice for
contesting in LP and HP categories, as well as for DXing.  But so far I have
not been enamored with the noise reduction system.

Thanks and 73,

John, WA6L

[Elecraft] KDVR3

[Mike Harris]

G'day,

Maybe I'm blind but I cannot find much information on the utility of the 
KDVR3.  There doesn't seem to be any published specifications.

The last page of the installation manual refers you to "detailed 
instructions for using your digital voice recorder are included throughout 
the K3 Owner's Manual".

Well not a lot of detail there either.  p29 is as good as it gets and that 
offers more questions than answers:

1.How many seconds of recording.
2.It is stated that "recording starts at the beginning of available 
space each time it is started, and will stop at the end if not terminated 
sooner".  This would imply that memory is not divided equally between 
M1-M4 but is dynamically available, depending upon the length of the prior 
recordings.
3.How is memory erased.
4.I assume that if recorded received audio on playback is heard on the 
K3 speaker/phones it can also be sent to line out to enable archive on a 
PC.

Don't you just hate those buttons that flash up a not installed message. 
Fitting the KDVR3 would also offer a good excuse to do the front panel 
microphone circuit mod whilst the front panel is in pieces again.

Regards,

Mike VP8NO

Re: [Elecraft] RX EQ comments

[Leigh L. Klotz, Jr WA5ZNU]

Not to mention the effect on data modes...supposedly this is on the list.
Leigh/WA5ZNU
I set up the RX EQ for a boost at 400 and 800Hz for CW. I also lowered 
the others which had the effect of reducing noise. The results were 
good. I then listened to some SSB and realized that the equalized 
settings were the same as I had set for CW. I couldn't find a way to 
have one group for CW and another for SSB. It seems like there should 
be unique settings for the different modes.

Re: [Elecraft] KDVR3

[lyle johnson]

1.How many seconds of recording.


TX MEMORIES

Each transmit memory is up to 15 seconds in length.

There are eight (8) memories, arranged as two (2) banks of four (4), just like 
the CW and Data memories.


RX MEMORY

There is a 90 second "endless loop".  New recordings are appended to the nests 
audio in the loop, and the oldest is earased as more audio is added.


2.It is stated that "recording starts at the beginning of available 
space each time it is started, and will stop at the end if not terminated 
sooner".  This would imply that memory is not divided equally between 
M1-M4 but is dynamically available, depending upon the length of the prior 
recordings.

3.How is memory erased.


In the case of the TX memories, record something new.  It might be extremely 
short (44 milliseconds).


In the case of the Rx loop, you don't erase it, you just record over old 
audio.


4.I assume that if recorded received audio on playback is heard on the 
K3 speaker/phones it can also be sent to line out to enable archive on a 
PC.


I make the same assumption :-)

The DVR Rx palyback audio substitutes for the main receiver audio just prior 
to the AF GAIN control so you can adjust its level on playback.  It is also 
routed to LINE OUT.

a 1296 transverter to it. using the kxv3 transverter ports, i have receive on 
1296 eme, but no transmit power to the transverter. A sequencer puts the radio 
and other equipment into transmit and either cw or ssb then can be used. I see 
no power output out of either the transverter port or the ant 1 port. I have 
done a lot of reading, but nothing has worked yet, any suggestions?.Doug

[Elecraft] Musings on Noise Reduction

[Lee Trout]

John:  I agree:  The noise reduction on the K3 is poor.  To my ear, all 16
settings introduce distortion while providing minimal noise reduction.  And
yes, I have played around with rx eq settings.  My little Kenwood 480 has
much better N/R than the K3.

The N/R is my only major complaint about the K3.   I hope a firmware fix
soon.

Hi Lyle,

This could be interesting.

My KDVR3, according to UPS, is now already in Germany [KOELN (COLOGNE), 
DE  07/12/2008  21:25  IMPORT SCAN], which means with a bit of luck in 
less than about 18 hours it will reside in my K3 here in Munich.


It's almost like watching a race... Will the software be released before 
the hardware arrives??? hi hi


More seriously, do I understand correctly that the MCU 2.67 / DSP 1.96 
firmware does not support the DVR or is only a subset of DVR features 
supported by the current firmware?

This could be interesting.

My KDVR3, according to UPS, is now already in Germany [KOELN 
(COLOGNE), DE  07/12/2008  21:25  IMPORT SCAN], which means with a bit 
of luck in less than about 18 hours it will reside in my K3 here in 
Munich.


It's almost like watching a race... Will the software be released 
before the hardware arrives??? hi hi

RE: [Elecraft] Musings on Noise Reduction

[Roger Marrotte]

Lee,
 
Sorry to say that I've had the exact opposite experience.  I haven't had a
K2 for a few years.  I've had a K3 since July.   I worked some in the 160m
contest this weekend and with NR on I was able to remove just about all the
noise on the band and hear stations way way down in the noise.  I never had
that experience with a K2 and I've used three different K2s.  What I
experienced this weekend with my K3 was just phenomenal.  I worked about a
dozen DX stations some as far out as the middle east.  Without NR I wouldn't
have heard them at all.  I not sure why we have had such different
experiences.  I didn't have a hard time finding a NR setting that worked.
On occasion I would hear some band noise but most of the time it virtually
went away with the NR on.  I use a full size 160m dipole up about 70'.  It's
the same antenna I used with the K2s.  Perhaps if you were using a vertical,
the noise was more severe or just different.
 
Roger, W1EM

Re: [Elecraft] K3: New/ Old QSK

Paul, how does this compare with using Semi QSK with .01 delay.  It sounds
very similar to me--by ear--but I do not have the equipment to look at the
issues
you've investigated.

Thank you, Gary W7TEA

[NAQCC]

NAQCC Sprint Tuesday night!
This coming Tuesday evening will be the monthly NAQCC Sprint for December, 2008.

I will refer you to the proper URL:

http://www.usatek.net/~yoel/sprint200812.html

There you will find all the details as to time, frequencies and also a special 
prize.

This month's Special Award goes to the winner of a drawing among the highest 
scorers from each division who are able to make the word 'CHRISTMAS' from the 
calls of stations they work. Note: you only need to work one station with a 
letter "S" to get your two "Ss".

This is a monthly event that caters to the CW veteran, the CW newcomer, 
straight key and bug fans. All are welcome to participate (this includes QRO); 
but you must use QRP power levels to compete for awards.

Come join us and have a real good time!

FYI - The New/Old selection also applies to the external key line. 
Regardless of the delay setting, the CW transmit waveform does not change 
between QSK and Semi-QSK.  The Semi-QSK waveform still follows the Old/New 
selction as it does for full QSK.


To my ears, receive recovery time under Semi-QSK at 0.01 is still noticeably 
longer than under full QSK in either New or Old modes.  Also, in QSK, I 
don't detect any receiver recovery time difference between New/Old.


The only difference I've noticed so far is that keyed weighting is lighter 
under New by 4 ms, and at the moment of key closure, the RF envelope time 
starts at about 19ms versus 15 ms under Old.  The 4 ms difference is exactly 
the delta of the RF envelope duration between New and Old modes.  So far, 
I've not heard any anomaly that would cause me to switch from the Old to the 
New mode.


In a nutshell, I much prefer the Old mode and hope it does not go away in a 
future F/W release.


Paul, W9AC

Note my query in square brackets.

I'm about to set up my K3 with my computer sound card for WSJT
(DATA A mode) operation. You seem to imply above that it is
necessary to retweak the Mic Gain / Line In control every time you
go from SSB to DATA A and vice-versa. I would think the setting
for Line In would be remembered for the DATA A mode, once set. Is
this not the case? Is it necessary to adjust either Line In or Mic
Gain when switching back and forth? I sure hope not...

[Elecraft] Six-meter Antenna Tuner

[W6SX Hank Garretson]

Since it is part of the K3 package, I would like to try six 
meters.  My one and only antenna is an eighty-meter dipole 46 feet 
above ground fed with poly ladder-line.  I'm looking for suggestions 
for a 100-watt coupler that will tune a balanced-feedline antenna at 
50 MHz.  I do not have the K3 ATU and am looking for something 
considerably less expensive.


All ideas are welcome, but please don't suggest some other 
antenna.  My antenna is what it is.  Because of town esthetics and 
very harsh winter weather I'm lucky to have the antenna at all.

[Elecraft] Lost SSb after KRX3 install.. The end

[Howard K2HK]

Found the cause of my lost SSB after much hair pulling. It was not or almost 
not related to the install. The problem turns out to be in pin 1 in the front 
mike connector. I rewired the mike for the back connectors and voila audio is 
working. Too late to open things up tonight for an exact dx and tx but will get 
it in the AM. Thanks for all the suggestions which allowed me to eliminate 
several possibilities. This was not expected since I didn't get my big hands in 
that area.

[Elecraft] Elecraft CW Net Report for December 8th, 2008

[Kevin Rock]

Good Evening,
   That was interesting ;)  Twenty meters was less than optimal whereas forty 
meters was just noisy, weak, and filled with QSB.  It was also changing a 
minute by minute basis; still it was much better than twenty!  I know a solar 
stream was due to hit the earth in the last week but I have not been following 
the news.  I have been buried in other projects.
   The weather turned back to its typical Oregon rainy season mode.  Not all 
that wet but it is starting to get chilly up here.  My sister asked about snow 
but I don't think that will come until after Christmas.  January is when we 
normally get our greatest accumulations.  I have seen ten feet of snow on the 
ground but the older folks tell me it has gotten a lot deeper than that in the 
past.  I am not sure whether to believe twenty feet though but the trees have a 
certain look to them which tells of harsher winters than I have seen.  Whole 
swaths are snapped at between twenty and thirty feet above the ground in the 
older trees.  Those less than forty years old do not show this tendency.  
   On to the lists =>

   On 14050 kHz at z:
N0SS - Tom - MO - K3 - 008
K6DGW - Fred - CA - K3 - 642
KD5PZO - Pat - OR - K4 - 001

   I did forget to ask Jeff, W7BRS, for his information but he has it listed on 
his emails so I got a bye on that one :)  If there are any corrections, such as 
Pete using another rig ;) please send me the fixes and I'll get them into the 
database.  As I mentioned earlier the conditions were interesting.  Hopefully 
soon the sun will sprout some spots and propagation will improve.  It sure 
would come in handy during the fox hunts!  
   Please stay warm and stay well,

Re: [Elecraft] Musings on Noise Reduction

[WA6L]

I started this thread and I have been watching the replies with interest. 
Dick's question about AGC settings piqued my interest and I did some
additional research.

First, Lyle Johnson's message here:
http://n2.nabble.com/K3-AGC-Settings-Tutorial-td681120.html#a681120 does
much to explain the AGC settings.

Then, Fred KT5X's message here: 
http://n2.nabble.com/K3-AGC-settings-td395668.html#a395668 provided the
inspiration to put the AGC configuration settings on the PF1 and PF2
buttons.

Armed with this information, I spent an hour or so experimenting with AGC
and Noise Reduction.  I am pleased to say that I found a combination that
has vastly improved my NR experience.  The noise reduction is now working
pretty darn well with a setting of F3-2.  I won't go as far as to say its as
good as the K2's (yet) but it's getting there.

I urge you to do your own experimentation, but here are the settings I
landed on:

AGC THR = 7
AGC SLP = 12
AGC F = 100

Thanks, good luck, and please let me know if you come up with settings that
work for you.

73,

John, WA6L
