Re: [Elecraft] Audio feed back (I think?)

[GD0TEP]

Hi again Joe,

I'm using XP here. I've checked what you've suggested and found that it is
indeed a sound card issue. The output from the sound card also has the mic
listed as an option, when this I muted the feedback is gone. There's still
an issue with the sound blaster software taking control of the properties
and turning it back on, but I'll chase this up on the WSJT reflector.

Thanks again for your help Joe, very much appreciated here.

73,
Andy

Which operating system?

Most soundcards will default to monitoring on the line input.
If you're using Vista or Windows 7, open the Audigy 2 ZS Speakers.
Select the levels tab and make sure all of the devices below the line (all
of the inputs) are muted.  In Windows XP, I think you need to open the
"Advanced" features and turn off "monitor while recording" (or select "do
not monitor while recording") or something similar.

Re: [Elecraft] A few questions before ordering the K2 kit...

[jez]

Peter,

first thanks for your reply, I think it clears up some of the question marks
in my head!

In a project like the K2 there's always a big chance of me mixing something
up, but I have a bit of soldering experience and also own a proper soldering
station, so that assembling in the end should not become a problem (I
hope!). Thanks for the hints on how to calibrate the K2!

After reading all the helpful replies I think I'm (for the moment) going for
a K2 without the 100W option, but will prepare to add it (and the filter
add-ons) at a later moment.

The K3 looks impressive, and when I compare the prices there's really not
much of a difference when you add all options to the K2 which are included
in the K3 right away. Though I think building a K2 will give me some more
insight into how transmitters and receivers work - will think about it once
again, but for the moment this makes a big advantage for the K2.

Re: [Elecraft] A few questions before ordering the K2 kit...

[jez]

Jim,

thanks for clearing up some of my questions,

using a battery is indeed an interesting idea. Didn't think about it yet,
but as I probably own the smallest shack in HAM history at the moment I will
definitely think about that.

Thanks for the idea with putting the KPA100 in a separate EC2 with the
KAT100. I'll probably go for the K2 10W version for some months until I know
which configuration for the 100W PA / ATU options (internal / external) I
prefer.

Apart from that I have the KSB2 SSB option on my list, plus maybe (or later)
the KNB2 noise blanker and the KIO2 interface module. The K160RX 160-meter
add on unfortunately won't make much sense, as there's not much space for an
antenna.

Thanks for the email address, might be helpful as I have never wound toroids
before. I already have a bit of this enamelled copper wire and a old toroid
which I will first use to train winding and soldering.

[Elecraft] K3 DSP Board Upgrade Info

[Andy Wood]

I have recently ordered a K3DF DSP Low Pass Filter to add to the DSP board in
my K3. After reading through the relevant documentation, it appears my DSP
board is "Revision B" and therefore does not have the low frequency audio
mods for TX/RX either.

It seems that I could not find anywhere that told me exactly what the
changes were to effectively bring my DSP board up to the latest spec. I know
I could ship my board to Elecraft for upgrade, however the cost of the
shipping to/from Australia is expensive.

I have looked through both the early and current schematics and believe I
have a compiled complete list of the changes for the "Low Frequency Audio
Mods":

For my records, I have drawn circles around the changed components in the
relevant schematics and have these as individual pdf pages. If anyone would
like a copy, please contact me via email. it would be even better if someone
would offer to host them on their site / webspace?

Re: [Elecraft] K3/HL-1.2Kfx

[w5ov]

This subject comes up occasionally, and I would remind all of you that
Tokyo Hy-Power recommends the proper adjustment and use of ALC to provide
a safety limit on your power output from your radio - not a contast
"throttling" of your radio's output that would cause distortion like some
other solid state amp company seems to recommend(?).

ALC in the context of a solid-state amp is not equivalent to an amplifier
using tubes. Period.

So, bottom line, unless you are willing to assume the cost of repairs that
might be necessary due to overdriving a THP amplifier, one should not
advise to ignore the manufacturers' instructions.

Re: [Elecraft] PSK PTT doesn't work with USB to serial converter

[Brett Howard]

Heck a lot of the current quality DMM's will take this in stride...  One
of the tests we do when demoing meters (and I've seen it done commonly
from reviewers) is to run a meter through the different feature settings
while connected to the mains.  Often we'll just dump the probes into the
wall at 120VAC (or often 240VAC) then slowly turn the meters knob
through all possible settings.  Then run the knob back to off, remove
probes from the wall and power the unit back on.  If its not still
working perfectly and within its calibration spec we won't buy them.
Every Agilent and Fluke meter I've tried this with passed with flying
colors.

Re: [Elecraft] A few questions before ordering the K2 kit...

[lstavenhagen]

>And finally:  consider the K3.  The K2 was designed as the ideal Field
Day radio, and I think it is.  However, the 100-watt version is less
elegant than the 10-watt (my opinion only, of course), and the K3 has
several advantages:  it's more modern technology, it's more capable,
and it isn't much more expensive for comparable features.  The CW-only
K2 is an incredible value, but if you add SSB, KAT2, KIO2, and 6
meters the K3 is cheaper (? is that true?  pretty close, anyway.) <

This was actually the route I took instead of decking out my K2. So I would
also second this recommendation if your end goal is a fully featured rig
that supports all the modes, all bands, DSP etc. 

I.e. the base 10 watt K3 comes stock with SSB/RTTY/PSK31, etc support, audio
I/O, an RS-232 interface, 160 and 6M, DSP and other creature comforts that
make life really nice for certain things. When you actually push the pencil
across the piece of paper on it, the K3 actually ends up being the better
option in that case. It also has other things you can't get in the K2 such
as a high-stability reference osc., QRO internal ant. tuner (i.e. you don't
have to ditch the internal tuner when you install the 100W module), and
generally higher performance in the RX. 

However, the K3 doesn't offer the same kit building experience as the K2
because it's a modular, no-soldering kit. The K2 is a true box-of-parts to
fully functional rig experience, which I found to be great fun when building
mine. I was a first-time kit builder never having built a kit of any kind
before, so I had to go slow and prepare carefully by buying all the correct
tools etc.

I even wound my own toroids, which I still recommend even tho it's tedious
at times. You actually learn some things in that process that you probably
wouldn't otherwise...

But then again, my K2 is still bare bones with the noise blanker and
internal ant. tuner as the only options I've installed. I've pretty much
stopped there as that's the most glorious form for the K2, IMO.

So, IMO, I say do both! I'm a lot more broke now than I would have been if
I'd only done one of them, of course, but then again I'll never have to buy
another rig again if I don't want to.

Good on ohms and volts, but watch out if the meter passes that test when 
measuring current. We should at least have to change a fuse, otherwise any 
meter that would survive 120 volts in that test without opening a fuse would 
have significant burden when measuring current in a low voltage circuit.

Also, Brett, most of us, and most new hams cannot or do not buy Fluke or 
Agilent meters on our budgets, hi.  Unfortunately the price line we buy 
won't pass that test.  Just a thought.

[Elecraft] MH2 Microphone PTT button issue

[Tom Boucher]

There's an even simpler fix for an aching finger due to a stiff PTT button on 
the MH2 mic - push the XMIT button and push it again when you finish talking.

Re: [Elecraft] K3/HL-1.2Kfx

[Bob Cunnings]

I'm curious as to whether or not Lyle's assertion "The K3 does have
ALC output, but you shouldn't use it." will hold strictly true for the
future KPA500. I wouldn't be surprised at all if the tight integration
between K3 and KPA500 presumes the use of ALC since it's "there". If
so, I'll need to upgrade my early K3s, which shipped with the original
oddball ALC scheme, so it would be nice to know in advance.

Happy Independence Day!

[Elecraft] RFI Update

[K5RC]

The problem was isolated to the CAT plug. The only way I found it was that
when I physically touched the shell it was microphonic. In other words, I
could hear myself running my fingers across the connector in the headphones.
I unscrewed the jack-screws and the problem disappeared. MicroHam pots the
inside of the connector with white RTV, so it is impossible to know if there
is any sort of ground pin issue.

 

Thanks to all who sent suggestions, especially Rene at Elecraft.

[Elecraft] RX issue signal tracing

[Bob]

Greetings,
To recap, I have a bar or so of S meter, regardless of band, and the
cw signals are there, but not loud, crisp and prominent as on my K1
tuned to the same freq.
I built the crystal oscillator for signal tracing with a 30 meter
crystal, and it is powered by 12v.

Things seem to go wrong kinda where I expected, in the mixer, i.f. amp
and crystal filter.  Here are my findings.
Appendix E Troubleshooting, Page 10

During the build, I grabbed Q12, 2N7000, and soldered it elsewhere by
mistake. I removed it and resoldered it correctly when I discovered my
mistake, no power had been applied with the component in the incorrect
spot. Maybe I blew it up???

Re: [Elecraft] P3 Update

[Eric Swartz WA6HHQ - Elecraft]

We're darn close and the P3 is proceeding on plan so far. Everything has 
been released to production and we are just awaiting delivery of the 
final production sheet metal and stuffed PCBs. We're also refining the 
firmware as we go through field test over the next couple of weeks. 
Based on where we were a week ago, my best estimate is somewhere between 
7/15 and 7/25 for initial shipments. It will then take about 4-5 weeks 
to ship all of the rather large backlog.

Unscrewing the jack-screws provided a mechanical strain relief between
the plug and the KIO3.  I would bet the problem still exists in the
KIO3 you are just no longer exciting the problem because you removed
the screws.

 > MicroHam pots the inside of the connector with white RTV, so it is

Rig control would not work if there were a ground pin issue since the
signal ground (pin 5) and frame ground are separate (according to the
schematics).  You can always check the pin 5 connection on the micro-
HAM cable (cable schematics are available on the web site but look
for continuity between pin 5 of the DB9 and shell of the DB37).

BY the way, the silicone potting is added strain relief ... too many
users insist on disconnecting cables by pulling on the wires and not
the connector (plug) bodies.  Even though the cables have always used
the crimped and/or clamped strain reliefs in the various plugs, adding
the silicone potting has significantly decreased the incidence of
failure in the field.

Re: [Elecraft] K3/HL-1.2Kfx

[Lyle Johnson]

> I'm curious as to whether or not Lyle's assertion "The K3 does have
> ALC output, but you shouldn't use it."

Lyle never said that.  Someone was quoting my response and had my name 
at the top followed by their assertion, and my comments a few paragraphs 
down.

In fact, the K3 has ALC *input* that is compatible with most amplifiers, 
assuming the K3 has the negative ALC mod.  The negative ALC has been 
standard in production for the K3 for many, many months now.

In general, I suggest you set the K3 to run the amplifier at its normal 
level, and have ALC connected in case something goes mildly wrong and 
the amplifier requests drive be reduced , but before the amplifier 
faults and goes off-line.  One should never crank up the 
transmitter/exciter to the amplifier, and then use ALC to throttle back 
the drive as this usually  leads to splatter and other undesirable traits.

The ALC has not yet been activated in the KPA500, but will be soon.  My 
prototype KPA500 is operating nicely on the air with today's KPA500 
firmware update :-) . I set the drive from the K3 to get about 450W to 
500W on peaks. The amplifier is good to well over 600 watts, so that 
leaves plenty of margin, better IMD, etc.

Lyle KK7P

Re: [Elecraft] K3 Repair

[Eric Swartz WA6HHQ - Elecraft]

Hi Ed,

Sorry for the delay replying to this thread. I've been out of town for 
ten days and am just now catching up with older emails.

I just checked and we're running at 3-4 weeks right now for repairs and 
upgrades. My target is 2 weeks or better. I was in the factory yesterday 
and personally looked at the queue. The majority of the K3s awaiting 
work are for customer requested factory upgrades on older units, factory 
additions of new options, followed by a fair number with significant 
lightning damage (we see that this time each year) and a remaining mix 
of normal repair issues. We had the queue down to a shorter time 
recently, but the recent rush of radios coming in before field day (for 
upgrades, factory alignments and deferred repairs)  pushed us back a 
bit. We are also down one repair technician (part time) after they 
returned to the job they had been laid off from in Silicon Valley. What 
caught us off guard has been the number of people asking us to upgrade 
older used K3s to the current revision levels and adding options along 
with the larger number of K3s damaged from lightening strikes and other 
physical damage. We also had a number of K3s recently returned for 
repair after customers mistakenly transmitted into them while preparing 
and testing their SO2R set ups for the WRTC competition in Moscow next 
week and weekend. (The largest numbers by far of any rig used by U.S. 
and other country WRTC teams are K3s.)

Our tech crew has been working overtime to get things back below two 
weeks. Rene was in yesterday working hard when I checked in to pick up 
some items at the office, and Dale has been working extra hours in the 
evening and weekends. I'm also assigning some of our regular production 
crew to perform returned K3 dis-assembly, re-assembly etc so the repair 
techs can focus on what they do best. If all goes well, we should be at 
the two week or better target in the next 1-2 weeks.

73, Eric  WA6HHQ

Re: [Elecraft] PSK PTT doesn't work with USB to serial converter

K3 purchase.  Its one of those things that can be seen as one of the
best of breeds and will last you a long time.

Re: [Elecraft] K3 Repair

[Sam Morgan]

read the following 2 emails,
the first is from a elecraft owner
the 2nd a reply form on of the 2 elecraft owners

once again I will ask,
when is the last time you heard of any such interaction
with one of the big three?
I'm certain you will get no such about anything the sell

===
Hi Guys,

Please don't misunderstand my original question. (And thanks to all who have
contributed to an interesting discussion.)

I had been inactive for quite some time when I purchased a K2. That purchase
not only returned me to the hobby, but it also made me, probably, a lifetime
Elecraft devotee. I will be purchasing either a "tricked out" K2 or a K3.
The Asian manufacturers are not in consideration.

Please note that it is not my intention to be critical of Elecraft or the
K3. I understand the technology changes that have mandated a slight change
to the Elecraft business model where we are dealing, more or less, with a
line replaceable unit (LRU) concept radio as contrasted with a component
level repair model like the K1, K2, and KX1.

I am only trying to get an idea of the scope of the "problem", if there is
one. The repair times for the K3 seem to indicate a long queue and I
naturally wonder what is in that queue. If it is filled with K3's, I wonder
why.
My life has changed from employment to retirement; every dollar is very
important to me in this new fixed income world in which I now live. If there
is some kind of quality control issue developing with the K3, I would like
to get a handle on it so that I can make an informed decision about a (2nd)
K2 purchase versus a more expensive K3 purchase.

I would not expect a zero defect business model to be in place at Elecraft.
Having said that, however, I would like to obtain and understand the
"out-of-the-box" and the "infant mortality" failure rate data for the K3, if
such information exists.

Thanks,
Ed, KD3Y, PE (electrical)

Reply from Eric 1/2 owner below:

Hi Ed,

Sorry for the delay replying to this thread. I've been out of town for
ten days and am just now catching up with older emails.

I just checked and we're running at 3-4 weeks right now for repairs and
upgrades. My target is 2 weeks or better. I was in the factory yesterday
and personally looked at the queue. The majority of the K3s awaiting
work are for customer requested factory upgrades on older units, factory
additions of new options, followed by a fair number with significant
lightning damage (we see that this time each year) and a remaining mix
of normal repair issues. We had the queue down to a shorter time
recently, but the recent rush of radios coming in before field day (for
upgrades, factory alignments and deferred repairs)  pushed us back a
bit. We are also down one repair technician (part time) after they
returned to the job they had been laid off from in Silicon Valley. What
caught us off guard has been the number of people asking us to upgrade
older used K3s to the current revision levels and adding options along
with the larger number of K3s damaged from lightening strikes and other
physical damage. We also had a number of K3s recently returned for
repair after customers mistakenly transmitted into them while preparing
and testing their SO2R set ups for the WRTC competition in Moscow next
week and weekend. (The largest numbers by far of any rig used by U.S.
and other country WRTC teams are K3s.)

Our tech crew has been working overtime to get things back below two
weeks. Rene was in yesterday working hard when I checked in to pick up
some items at the office, and Dale has been working extra hours in the
evening and weekends. I'm also assigning some of our regular production
crew to perform returned K3 dis-assembly, re-assembly etc so the repair
techs can focus on what they do best. If all goes well, we should be at
the two week or better target in the next 1-2 weeks.

73, Eric  WA6HHQ

Sorry about the wrongly attributing  that remark to you, Lyle.

Yes, I understand the case where ALC is mis-applied as a form of drive
control, it's been frequently discussed here. It was the "last ditch"
amplifier protection case mentioned by W5OV in an earlier message that
to my mind seemed possible and maybe even recommended in the case of
the K3/KPA500 system. That's why I asked - I wondered if the KPA500
will provide ALC output and if the amp protection case would be
supported. Since it will be, and seems a desirable equipment safety
feature, I'll plan on updating my older K3s to be compatible. It's
easy nowadays with the availability of the REMIOUPGD KIO3 replacement
boards.

Re: [Elecraft] K3 Repair

[Grant Youngman]

What I find remarkable is that Elecraft is even willing to look at a radio that 
has suffered lightening damage.

Back in the mid-90's I took an indirect lightening hit that left a bit of 
molten metal around the shack.   Two other radio top 3 manufacturers were 
totally unwilling to even attempt repairs.  The policy was -- "Lightening 
induced damage, we won't touch it".  Nonetheless, I had to send the radios to 
the manufacturers, and pay for 2-way shipping plus a "service" fee,  just to 
get a letter to give my insurance company stating the equipment was 
"unrepairable".  It might have been, or not, but the service departments 
wouldn't even check.

Re: [Elecraft] K3 Repair

[Guy Olinger K2AV]

That's not as much a dig as it might sound.  A common occurrence after
lightning damage is for components to weaken and then fail later on,
on their own inconvenient schedule.

A question for the K3 repair guru's...is a lightning damaged board
replaced and tossed, or repair of the lightning damage attempted?  Is
the warranty for such repair the same, or is there a caveat for
lightning damage?

73, Guy.

Re: [Elecraft] K3 Repair

[Grant Youngman]

Actually, wasn't a dig.  I understand why there would be reluctance to touch a 
lightening damaged radio, given the issue you (and the vendors at the time) 
raised.

Which is why I'm kind of surprised Elecraft would do it, unless there were a 
caveat in the fine print :-)

Re: [Elecraft] K3 Repair

[David leDuc]

I started this thread last week. I was just venting. I really didn't expect
as much discussion.
It is nice to know that the principals at Elecraft actually read this
discussion group and pay attention if they think it is necessary. 
I know that the K3 is unequivocally the best performing radio available for
any price. I think that they want their service to be the same.
At least my K3 is on the shelf in Aptos and I don't have to worry about
lightning damage:)

[Elecraft] Mic Set-up

[David Guernsey]

Recently changed to the Elecraft MH2 mic on my K3 (SN 4052).  When I tried to 
set-up the mic for SSB transmit, I noted no indication in the ALC graphic when 
I keyed the mic.  Tried it at a mic setting of 20 and again at 40.  Mic is 
hooked to K3 with front panel mic input.  Any ideas?

Re: [Elecraft] K3 Repair (Lightning damage)

[Don Wilhelm]

Guy,

I have repaired several lightning damaged K2/100s.
To protect against a re-repair within my 90 day warranty period, I 
arbitrarily replace all the active devices in the KPA100 and then do any 
required repairs to the base K2, usually replacing at least the firmware 
chip - usually little else is required (that depends on whether the 
surge came on the antenna or the power cord or both)
I have done 4 so far with no ill effects nor complaints from my 
customers afterwards.

One caveat that I must adhere to is that if there is visible damage to 
the board, that is an indication that possibly capacitors, inductors, 
resistors and relay points have been damaged too, and I would advise the 
customer that it is not repairable at a cost less than that of a new unit.

I don't know if Elecraft has a policy on this sort of thing or not, and 
I certainly don't know about the K3 question.

73,
Don W3FPR

[Elecraft] A thought regarding new radios

Some companies bring out new transceiver models every year or two. Our  
philosophy is different. We'll continue improving the K3, protecting  
your investment. Similarly, the P3 and KPA500 will extend the  
capabilities of the K3 without any need to replace the rig itself.

Re: [Elecraft] A thought regarding new radios

[Brett Howard]

And don't forget you also improve value by not having to pay for
features that you won't use.  Don't need a tuner?  You don't have to pay
for one...  Don't want two receivers?  You don't have to pay for both of
them...  

Then on another note...  Want two receivers but don't have the money to
pay for one now?  Get on the air with part of the radio and add that
which you want later...  

My family loves my K3 as it has made for an avenue of Xmas presents for
the guy who has everything for a few years coming now... ;)

[Elecraft] (K3) Saving and Recalling M1-M4 per-band quick memories

[d_joyce]

 
 








Perhaps someone can clarify / correct my use of the per-band quick memories.  
I'm using M1 to M4 to save sub-band frequencies and filter positions with BW 
settings in each of the bands 160 thru 10 and having a problem.
 
Installed roofing filters are 2.8, 1.8, 1.0, 400 & 250.  Firmware is 4.03 / 
2.60.
 
For example on 20 Meters if I save 14,010 and BW of 450 using FL4 with V>M, M1 
- I can recall it correctly with M>V, M1.  If I save 14,195 and BW of 2.1 using 
FL1 with V>M, M3 - I can recall it correctly with M>V, M3.
 
The problem is with two data modes memory settings on 20M at M2 & M4.  If I 
save 14,080 and BW of 450 (and dual passband) using FL4 (for RTTY) - that saves 
and recalls correctly to / from M2.   However, if I save 14070 and BW of 3KHz 
(for PSK) using FL1 and save it to M4, then go to one of M1, M2 or M3 freq BW 
set and then try to recall M4 it comes up at the correct frequency but the 
filter BW is now back to 450 Hz using FL3 (the setting I used for M2). (The 
filter graphic seems to be correct but the actual filter is not as previously 
set.)  It seems that there is only one allowed set of BW and Filter setting for 
the two Data modes.  (I'm using FSK-D for RTTY and PSK-D for PSK).
 
Can anyone offer an explanation or correction of what what I'm doing wrong? Or 
is this a limitation of what can be saved in the memory positions M1 - M4? 

 

The manual isn't really too clear on this level of detail.
 
Thanks & 73

And don't forget you also improve value by not having to pay for
features that you won't use.  Don't need a tuner?  You don't have to pay
for one...  Don't want two receivers?  You don't have to pay for both of
them...  

Then on another note...  Want two receivers but don't have the money to
pay for one now?  Get on the air with part of the radio and add that

Re: [Elecraft] PSK PTT doesn't work with USB to serial converter

[Casey]

Windows DM says everything is fine. Tried various settings of the 
device, no change.  I dug up another USB-to-Serial in the junk box and 
it is definitely Prolific.  It appears to trigger PTT with that one (not 
totally sure, but the rx mutes), but no audio gets through so maybe 
not.  However, it doesn't release the rig from mute/PTT, whatever state 
it's in.   I put the cable back on the desktop and all works there OK.  
Haven't had time to take stuff down to the bench to check voltages yet.

Re: [Elecraft] (K3) Saving and Recalling M1-M4 per-band quick memories

[Wes Stewart]

Looks like you found a bug.

Perhaps someone can clarify / correct my use of the per-band quick memories.  
I'm using M1 to M4 to save sub-band frequencies and filter positions with BW 
settings in each of the bands 160 thru 10 and having a problem.
 
Installed roofing filters are 2.8, 1.8, 1.0, 400 & 250.  Firmware is 4.03 / 
2.60.
 
For example on 20 Meters if I save 14,010 and BW of 450 using FL4 with V>M, M1 
- I can recall it correctly with M>V, M1.  If I save 14,195 and BW of 2.1 using 
FL1 with V>M, M3 - I can recall it correctly with M>V, M3.
 
The problem is with two data modes memory settings on 20M at M2 & M4.  If I 
save 14,080 and BW of 450 (and dual passband) using FL4 (for RTTY) - that saves 
and recalls correctly to / from M2.   However, if I save 14070 and BW of 3KHz 
(for PSK) using FL1 and save it to M4, then go to one of M1, M2 or M3 freq BW 
set and then try to recall M4 it comes up at the correct frequency but the 
filter BW is now back to 450 Hz using FL3 (the setting I used for M2). (The 
filter graphic seems to be correct but the actual filter is not as previously 
set.)  It seems that there is only one allowed set of BW and Filter setting for 
the two Data modes.  (I'm using FSK-D for RTTY and PSK-D for PSK).
 
Can anyone offer an explanation or correction of what what I'm doing wrong? Or 
is this a limitation of what can be saved in the memory positions M1 - M4? 

 

The manual isn't really too clear on this level of detail.
 
Thanks & 73

Re: [Elecraft] Elecraft SSB Net results (7-4-10)

I had S3 noise with barely SSB signals underneath, and those that I

Hope to try again next week.

[Elecraft] [K3] Key Clicks or just Key Click Artifacts ?

[Phil Hystad]

I was hunting around for some action today on the 20 meter band with CW.  Did 
not find anything but I discovered an unusual key click which I am not sure if 
it is a real key click or not or maybe just some artifact of the sidetone 
monitor.

Since I was looking for stations, I was playing with the RF control a little 
bit and I noticed that if the RF control is advanced much past 12 oclock or 
maybe 1 oclock that key clicks were generated.  As you advance the RF control, 
the key clicks get stronger and bolder (whatever I mean by that).  At the time, 
my filter was fairly wide at about 1000 Hz so I started closing it down and 
about 350 Hz or so the key clicks disappeared.  These values though change 
depending on how far my RF is advanced versus the filter width.  With the 
filter down to 250 Hz or so, I can have the RF advanced almost all the way and 
the monitored signal is clean.  By the way, my smallest roofing filter is 400 
Hz 8-pole.

Now, those are the symptoms.  I am guessing that I am filtering out the key 
clicks by tightening it up with a smaller width.  These clicks occur whether in 
TX or in TEST mode and exactly the same symptoms.  I did about 20 minutes of 
testing and playing around with all kinds of adjustments in TEST mode.

So, does anyone else see these clicks.  Are they a generated artifact of the 
sidetone monitor or are these clocks actually TX'd and sent out.  No, I am not 
setup to listen to my own signal over the air and besides, given the 
interaction with the RF control, I really think they are not part of my TX 
signal.

Does anyone else see these?

I am still not an expert on a correct setting for the RF control versus the AF 
level.  I have a tendency to play between the two to get the best signal but 
without too much noise.  By the way, I very rarely use noise reduction (NR) -- 
it is almost always off on my K3 because I have not yet learned how to use it.  
Most of the time, the noise is not an issue and NR does not really seem to be 
needed.

Thanks for any comments or help.  If someone could confirm that this is normal 
and generated internally only (not TX'd) then I am fine (sort of) --- when 
TXing I can always back off the RX control anyway to remove the clicks.

73, phil, K7PEH

Re: [Elecraft] (K3) Saving and Recalling M1-M4 per-band quick memories

[Brett Howard]

Ok not sure if I am understanding this wrong or not...  But I've
configured my M1-M4 as follows:

M1 = 14.0 - 14.15 - CW mode - width 350Hz
M2 = 14.15 - 14.35 - SSB mode - width 1.5K w/ a shift of .95
M3 = 14.03 - 0.000 - Data Mode (FSK D) - width 500Hz Dual PB
M4 = 14.03 - 14.06 - Data Mode (PSK D) - width 1.5Khz

I was then able to recall these just fine...  However as soon as I
tapped HI/WIDTH twice to view the width it would then update the
passband icon and  show the BW to be 500Hz.  Then subsequent
recallings of M4 recall the memory with a 500Hz BW.  Does seem like
something is slightly amiss there...

Re: [Elecraft] [K3] Key Clicks or just Key Click Artifacts ?

[Steve Ellington]

You should not be hearing clicks when sending cw unless what you are hearing 
is just the band noise between cw characters. You say it goes away when 
turning down the RFG? Well then that's probably all you are hearing, just 
band noise popping off and on. I seriously doubt if you are transmitting 
clicks with a K3.

Re: [Elecraft] K3 Repair

[Jim McDonald]

My K3 was one of the lightning casualties they (René) just fixed.  If it
wasn't cost effective to replace components on a board, he replaced the
board.  Neither René nor Madelyn said it couldn't be completely repaired. I
think the modularity is what makes it possible to ensure that a lightning
repair produces a radio that is completely up to spec (and updated too).

René explained his findings and course of action to me, and I was and am
very satisfied.  Insurance would have paid for a replacement if Elecraft
would have said one was necessary, but I am comfortable that the repair was
complete and left the radio as good as new.  He charged me for four hours of
labor and the components and boards replaced.  The radio was new last
November or so, so it is in the warranty period, but I assumed the warranty
wouldn't cover lightning.

-Original Message-


That's not as much a dig as it might sound.  A common occurrence after
lightning damage is for components to weaken and then fail later on,
on their own inconvenient schedule.

A question for the K3 repair guru's...is a lightning damaged board
replaced and tossed, or repair of the lightning damage attempted?  Is
the warranty for such repair the same, or is there a caveat for
lightning damage?

to get a letter to give my insurance company stating the equipment was
"unrepairable".  It might have been, or not, but the service departments
wouldn't even check.

I too would place lightning damage into the "Acts of Nature" category 
and not a warranty consideration.  A warranty covers premature component 
failures and failure to perform to specification, which is different IMHO.
For a comparison example, a new automobile has a warranty period, but if 
a tree falls on it and it is damaged, would that be a warranty repair? - 
I think not - that is why we have insurance coverage for those kind of 
catastrophic events.

Re: [Elecraft] (K3) Saving and Recalling M1-M4 per-band quick memories

[Wayne Burdick]

Hi Doug,

Filter bandwidth is stored per-mode. At present, all data sub-modes  
share the same bandwidth. I'll look at what would be required to split  
them out.

Meanwhile, you could use the user-programmable NORM settings, 1 and 2,  
to switch between two often-used bandwidths in DATA modes. See page 24  
of the owner's manual.

[Elecraft] Elecraft CW Net Report for July 4th & 5th, 2010

[Kevin Rock]

Good Evening,
   Conditions were strange today.  I was able to work all over the place but 
where my signal landed was spotty.  As far east as Connecticut and Georgia but 
not much in between.  I did get Michigan and Colorado but the West Coast seemed 
to be favored.  I expect a lot of folks were otherwise engaged but the band 
noise on 40 meters was not high.  This normally means propagation is not good 
during the summer months because I should be hearing storms. 
   I need to get my boots on and a warm jacket so when I climb up the mountain 
to the lookout I can stay warm.  The temperature only rose to 62 today but now 
it is getting cooler again and there may be a mist from the ocean.  Hopefully 
my view of all the local fireworks displays will not be blocked by low clouds 
or rain.  The forecast is for another day of chilly temperatures but then we 
will go into the 80s.  That will be nice.  I can stop burning a fire to stay 
warm for a week or so.  

  On to the lists =>

 On 14050 kHz at 2200z:
KL7CW - Rick - AK - KX1 - 798
K4JPN - Steve - GA - K2 - 1422
W0RSR - Mike - CO - K2 - 5767
K1THP - Dave - CT - K3 - 686
K0DTJ - Brian - CA - K3 - 4113
N08V - John - MI - K3 - 820

 On 7045 kHz at z: 
K0DTJ - Brian - CA - K3 - 4113
KL7QOW - Mike - AK - K3 - 3144
K6PJV - Dale - CA - K3 - 1183

   Hopefully the propagation will improve for next week's nets.  Then we can 
see who will come out of the woodwork and join in.
   Until next week stay well,
  73,
 Kevin.  KD5ONS  (Net Control Operator 5th Class)

Re: [Elecraft] K3 Repair

[Philippe Trottet]

Fully agree with your comments Don, 
 
And I want to take the opportunity to encourage every Ham to pay more attention 
to protect our lovely K's and all ellectronic devices in the house.  I've seen 
so many locations who are facing huge lightings storms and this does not happen 
only to others, I'm a survival !
I do not want to start a thread beacause it is not directly related but I will 
be happy to share my experience with those who are interesed.
 
To have some ideas what it is done today on lightning protection, please have a 
look at: 
http://www.indelec.com/foudre/Comprendre_la_foudre/Comprendre_la_foudre.aspx 
I have no interest at all in this company but I have always pay very much 
attention to be well protected in the various locations I was playing Ham 
specially after an lightning hit when in France (F5LTB)
When in 2003,  I arrived in Democratic Republic of Congo (9Q1TB), where 
lightning protection is mandatory I was looking to the companies who can 
provide such service and discover that one has a different and a technically 
interesting approach. I have equipped my house and during the 5 years I stayed 
in Kinshasa and never face any problem even the head of the lightning device up 
to my antenna system on  my metallic roof has been hitted many times by direct 
lightings, my younger son can testify, the noise amplified by the metallic roof 
was really impressive, but none of the electric/electronic devices has been 
destroyed.
The skyscraper where I'm living in UAE is already lightning protection equipped 
and apart of the strong lightnings during the "colder" season it is very useful 
 because we are facing time to time sand storms who induce an important amount 
of static.
Have a good day
