Re: [Elecraft] problem installing k-line side panels

[Don Wilhelm]

Dave,

The nuts and lockwashers are not going to stay in place, you will have 
to mount the side panel and then insert the screws.  After that, put the 
lockwashers on and then the nuts.  It is not difficult, just a bit 
"tedious".

Re: [Elecraft] ProAudio Engineering KX33 Power Supply

[Howard Hoyt]

Hi Ed,

Response to step load changes is a mostly unpublished parameter of power 
supplies in general.  Both linear and switching supplies have time 
constants in the voltage control circuitry, and both can be poorly 
designed.


Designing a linear regulator can be potentially more simple, as most of 
the components affecting the steady-state and dynamic characteristics of 
the supply are designed into the control IC and a few external 
components.  This takes most of the performance characteristics out of 
the hands of the manufacturer of the supply. Indeed most linear 
regulated supplies like the Astron are mere executions of application 
note designs offered by the manufacturers of the regulator ICs.


The performance of switchers can depend more heavily on design 
execution, as the characteristics of the inductive and filter components 
can affect the regulation.  Our testing has shown the Kx33 running 14.2V 
to have less than 10mV of overshoot when returning to receive mode from 
a 2.7A KX3 transmit load.  At least one inexpensive switching supply 
spiked to over 19V in this same test.  This is caused by the response 
time of the switcher's duty cycle servo to output node voltage changes 
and is not to be confused with its output impedance causing voltage drop 
with load.  We are working on an addendum to the test reports published 
on our website which will show load step response of competing supplies 
along with currently available ripple and static voltage regulation specs.


Cheers & 73,

Howie - WA4PSC

Re: [Elecraft] OT Mystery QRM Help (Video)

[Fred Townsend]

Gentlemen: 
That is not a dirty signal. It's very clean with about a 2 KHz wide SSB. The 
sidebands are very clean. I'd say you have a beacon or some other intentionally 
caused signal. It may be modulated by some grey line effect but the pulses are 
consistent as I can tell hearing only 4.

You can download the assembly manual from the Elecraft website.  Look around pp 
50-52 for right side panel installation.

Re: [Elecraft] OT Mystery QRM Help (Video)

[Ken G Kopp]

Hi Dave!

In a past life I was a noise technician for a large electric utility.

WAG's:

Solar cell controlled street light.  Had one a block away about a year
ago.  Came on dimly and slowly got to normal brightness and noise
diminished as got brighter.

Is your area cold enough that someone has placed a heat tape in an eve
trough or downspout?

A timer or photo cell controlled flood light that might not be making good
contact in some manner?

Electrically heated floor?  Once hosted in a state park that had yurts with
electrically heated floor tiles.

Touch lamps are notorious noise sources.

On-demand water heater that is activated when someone gets home from work.

Are there any heated critter drinking pans or tanks nearby?  How about a
hot pad or electric blanket in a dog house?  Had one next door some years
ago.

A neighbor with grow lights?  A heated bed for plants in a green house?

The possibilities are infinite 

73!

Re: [Elecraft] Genovation Keypad on teh K3/P3, solved

[Wes (N7WS)]

I'd be interested in seeing it interfaced directly to the K3 without the 
necessity of having a P3.


I considered buying one of these some time ago to play with but their only 
distributors were in Phoenix, where I am most definitely not.  One of them 
wanted to charge me Phoenix sales tax since I"m in AZ.  I went so far as to 
email him the Phoenix City Code to prove that this was unjustified.  He didn't 
care.  The other one was also in Phoenix and wanted to charge shipping based on 
the cost of the item.  So shipping a pound of $100 bills would cost a fortune 
but shipping a pound of iron would be cheap.  I suggested to Genovation that 
they find some other distributors. I'm pleased to note that Amazon has them now.

Hi,

It's not that difficult, most of the work is just programming the P3
macros into the P3 as Elecraft instructs you to do.  Which was harder to
do than prepping the Genovation, as I used an external keyboard on the
P3.

Once the Keypad is updated, I just enter the triggers one time, hit the
download button on the keypad software, and I am done forever
programming the keypad.

The keypad triggers the P3 to fire its macros, so you just program the
triggers in once, and on the P3 make sure they match.  If you want to
change macros, just change the P3 keeping the same trigger.  The
triggers are arbitrarily selected.  I used 1-z, 1-0, and F1-F12, one for
each key.  Then I just program the P3 to fire a macro on the appropriate
trigger.

The trick is in getting the triggers to match, and that is taken care of
by the chart you can download.

The write up makes it look a lot worse than it is because of the detail
level.  The entire process took about 3 minutes to prep the Genovation,
and the rest of the time was spent making macros on the P3.

Once the Genovation is programmed I never program it again...  All it
does is trigger macros from the P3.

I must say, that after using the external keypad for a few hours on a
pileup it is nice...  I almost never touch the K3 anymore.

Re: [Elecraft] Kenwood TS-590SG with KPA500 amp?

[Mark Goldberg]

I can't add much more, but the recent KPA500 software supports the
serial connection to the TS-590. You don't really need it, but it
helps by switching to the right band before you transmit, for example
if you are working crossband spit it switches to the band you are
going to be transmitting on rather than where you are receiving on. I
have usb to the computer and RS232 to the KPA500 and everything works.
It is just extra belts and suspenders, but it works well. The
frequency based switching does too.

I still manage to screw something up in haste about twice a month. The
KPA500 faults and lights up the big idiot light. A reset of the fault
brings it back on line with no problems.

Oh, I meant to add, I let the amp sniff RF and it just works.  No issues.

This is at my remote base where I have seen the amp start up at -20C
without issue and after time, I can actually get it up to 0C.  :)

The equipment is kept in a non-heated room and seems to work no matter
what.  I'm impressed.

Re: [Elecraft] Kenwood TS-590SG with KPA500 amp?

[Cliff Frescura]

I have an old TS-940 working with the KPA500.  I used the ACC amp
connections on the back on the Kenwood for PTT, which I believe is a DIP
mechanical relay - not loud at all.  In addition, the KPA500 sniffs the
RS-232 line between the Kenwood and my logging PC running DXLabs to
automatically switch bands on the KPA when the frequency changes via the
computer or via the radio.

Subject: [Elecraft] Kenwood TS-590SG with KPA500 amp?

Hello all:
I have a KPA500 on order to use with my Kenwood TS-590SG (and with my
Elecraft KX3). I would appreciate any suggestions on the best way to
interface the TS-590SG and the amp.
In reviewing the Kenwood manual and some of the Yahoo groups, it appears
that there are at least two ways to interface to the amp. The 590SG offers a
mechanical relay as well as a solid state relay for amplifier switching.
The mechanical relay is apparently fairly foolproof but is noisy. The solid
state relay is quieter or near silent but apparently has some issues in
keying the KPA500. I don't do CW, so rapid keying is not really an issue
with me.
I would appreciate any advice on the best way to interface these two. I
attempted a cursory scan of previous mail list posts but the number of
postings is voluminous. IS THERE A QUICK WAY TO SEARCH PREVIOUS POSTS?
Thanks all in advance for your responses!Steve, N5SKHWeatherford, TX

Re: [Elecraft] Kenwood TS-590SG with KPA500 amp?

[Michael Walker]

Steve

All HF amps the same regardless of the vender.

This pretty much sums it up.

http://rin3.blogspot.ca/2014/12/how-to-key-your-amplifiers-with-ts-590g.html


You can ignore the pin 7 part if that helps (that is option 2)

Pin 2 of the DIN connector goes to ground (or the shield of an RCA cable)
Pin 4 goes to the center of the RCA connector you'll need for the amp.

What that does is that when the radio goes into Transmit, Pin 4 is grounded
and that turns the KPA500 on in TX mode.

You don't require any external devices or additional keying relays unless
you like to wear a belt and suspenders.  :)

That should work just fine for decades.

I hope that helps, Mike va3mw

BAND6=B6 will work with the 1.6 KRC2 firmware.

XV1 with the standard mapping. You can set it to whatever you’d like with the 
KRC2 Utility.

Also, you can restore the original settings and mappings by holding the F4 
button at KRC2 power-up. This only works in the V1.6 firmware.

There is no official version of the KRC2 Utility for the Mac. I have one for my 
own use that might be usable by others. Is this what you are looking for?

The windows version is on the Elecraft site in the downloads and firmware

[Elecraft] ProAudio Engineering KX33 Power Supply

[Dauer, Edward]

Anyone have experience with the PAE KX33, particularly with a base K2?

On examination of the second incident of blown PA (and other) transistors
in the K2, and the fact that on both occasions I was using a MFJ supply,
and that the rig worked without incident when running for several hours on
a Power Werx supply, I have come to suspect that the MFJ supply created
transients which somehow escaped being regulated out.  It is now in the
trash.  Hence the need for a clean, light weight, reliable, and
well-regulated PS for the K2 when running low power, and for use with the
KX3.

All comments would be most welcome.  Tnx,

Ted, KN1CBR

Re: [Elecraft] Switching to Linux

[Mike Markowski]

The funny thing, Nate, is this is a project that Pf ik5pvx and I started 
back then.  There is a tradeoff between taking time to reverse engineer 
and time to get on the air.  After a decent amount of success, we opted 
for air time instead!  :-)  Especially after a week at work, a weekend 
making contacts was more fun.  I wouldn't recommend using the code 
except as a starting point for further reverse engineering.


I think someone else got further on such a project but can't recall the 
program name.  Maybe someone else can.

[Elecraft] Need help with 6 meter setup for KRC2 with K3

[Lewis Phelps]

I know this topic has been on the list before, but all the discussion I have 
found raises questions but doesn’t give answers. 

I recently acquired a used RKC2, which I’m trying to set up with my K3 
(barefoot version; 12 watts and no KAT3)

My question concerns the mapping for 6 meters.

The K3 manual refers to the Menu setting for the KRC2 as follows:
===

"Controls the KRC2 band decoder’s accessory output settings. Shows ACC OFF or 
ACC1-3 if a KRC2 is detected; - - if not.
To ensure compatibility with both old and new KRC2 firmware, two different 6 
meter band decodes are provided. Tap to select BAND6=B6 (addr=10) or BAND6=B10 
(addr=9). Refer to the KRC2 manual for further details. 


However, I am unable to find anything in the KRC2 manual that discusses the 
mapping for the 6 meter band.  Presuming for discussion that I have “newer” 
firmware installed,

1. do I want to select BAND6=B6, or BAND6=B10? 

2.  what control line in the KRC2 should I use to energize devices associated 
with my 6 meter setup (e.g. coaxial relays used to connect the main K3 antenna 
port to an external 6 meter amplifier, rather than to my HF antenna).

ALSO

I find reference in prior discussion to  a Mac version of the KRC2 utility, but 
I can’t find it anywhere online. Does it exist?  Where might I get a copy? 

For that matter, where can I get ANY version of the KRC2 Utility that’s used 
for band mapping of the device? The only thing I can find on the Elecraft site 
is a Download program, not the utility that allows you to modify band mapping.

In sum, is there actually a way for me to use the KCR2 with my K3 in such a way 
that I can control external devices used for 6 meters? The K3 and RCR2 manuals 
are beyond opaque in this respect — a disappointing variance from the usual 
clarity of documentation.

Re: [Elecraft] Anti Static Bench

[Alan]

I don't see anything on that web site that defines exactly what is meant 
by the term "ESD top".  I'd be leery unless you can find some more 
information.


Many devices advertised as "ESD mats" in fact do not work correctly - 
their resistance is too high to bleed off the static discharge in a 
reasonable time.  Several years ago I tested three different mats and 
posted the results on this reflector:


http://www.mail-archive.com/elecraft%40mailman.qth.net/msg94407.html

I recommend you not depend on the anti-static properties of any mat or 
other device unless they specify that it meets  ANSI/ESD S4.1 or 
ANSI/ESD S20.20.  If the only specification is that they use the words 
"anti-static" or "ESD" in the product description then be very sceptical.

Re: [Elecraft] Switching to Linux

[Hajo Dezelski]

Hello,

Cqrlog for logging. I used it as my main logging program.
Hamlib is ok, but you need an interface. Cqrlog does it, but I would
recommend Fldigi. There is even a logging program integrated.

One thing I would consider: Although Mint is ok and the group is active,
but it is always some months behind of the development. So you will not
always get the newest versions of the software. This would be not a big
problem, but the important fixes are also not delivered in a timely
fashion. So I switched to Debian. There you could also choose interfaces
like Cinnamon.

[Elecraft] Genovation Keypad on the K3/P3, solved

[P.J.Hicks]

I've been using a 24 key Genovations keypad on my KX3 for almost 2 years now. 
Love it. One button press to change all manner of things without having to 
remember all the steps and commands. 24 keys with the shift/toggle feature 
gives me 46 macros. 
  
I used msWORD and a template by VR2SS, IIRC, to add colors and text to the 
labels, then, as mentioned, cut them out and put them under the key caps. Very 
professional looking. It took a couple days to get done but I had no experience 
with KX3 macros nor the program so had the learning curve to deal with.

Re: [Elecraft] Switching to Linux

[Mike Markowski]

Bill,

Popular packages to consider:

1. Rig control: hamlib at http://sourceforge.net/p/hamlib/wiki/Hamlib/
2. Light weight logger: xlog at http://www.nongnu.org/xlog/
3. dxcluster: xdx at http://sourceforge.net/projects/xdxclusterclient/

4. Heavy weight logger: cqrlog at https://www.cqrlog.com/

Cqrlog is worth considering because it handles up/downloading to many 
qsl sites like Log of the Word, Clublog, etc.  But it uses MySql and 
sounds like it isn't the more minimal set up you're looking for.


I don't know of any linux K3 memory editors.

Good luck and you'll enjoy the change!  73,
Mike ab3ap

Re: [Elecraft] KX3 Feature Request

[Charlie T, K3ICH]

I have a brand new, never installed, WindCamp brand heat sink for the KX3.  All 
the mounting holes are drilled & countersunk for a neat & easy installation.
It is red anodized after milling and has a bare spot on the inside for more 
efficient heat transfer from the two RF output devices.
This is a well-made and very professional looking heat sink which should help 
significantly in keeping the temperature down when running the KX3 in the 
continuous modes.
The only reason I'm selling it is because it is an extra that I do not 
currently need.

I can send some pics if you'd like to see it first.

I will ship it in the US for $38.

[Elecraft] Switching to Linux

[Bill]

I have been a user of HRD for years, however, am now seriously 
considering a change to Linux Mint.


Is there a good rig control or memory manager for the K3 written for 
Linux users. I do no DX or contesting and I do not use any of the new 
digital stuff - so I don't need all that extra weight, unless it is 
easily ignored or removed.


For the interim, I am using the very capable Pigknob and may just opt 
for David Cole's new cottage industry keypad supreme.


Suggestions would be appreciated. Please note that I am going Linux - 
not dual boot or VM.


Thanks,

Bill W2BLC K-Line

I'm using a Mac, iMic and fldigi V3.23.00. It appears everything is set

I can't set the ALC to 4 solid with the 5th bar flickering. The minimum number 
of bars is a solid 5, the line in at that point is 4. It makes no difference if 
the iMic is set to Line or Mic. The audio cables are stereo.

[Elecraft] Anti Static Bench

[Richard Thorne]

I've been in my shop for 4 years now and I finally have a plan on how I 
want to finish it out.


One of the features will be a place to build kit's or work on my K3's 
which requires an antistatic mat.


I saw one of these in a catalog that came across my desk at work. 
http://www.uline.com/BL_3853/Industrial-Packing-Tables?keywords=table 
One of the table top options is made out of ESD material and has a 
ground strap.  I would just by the table top, not the bench and 
incorporate it into my remodel.


Has anyone ever used one of these.  Pro's, Con's?

Thanks

Myron,

It will already do that.  You apparently have the VFO OFS menu parameter 
set to OFS - change it to OFF and you will have your wish.
Note that if you have VFO OFS parameter to OFS, the step size will vary 
by the value set in VFO CRS.  The size setting is per mode.

See those menu items in the manual.

Re: [Elecraft] K3 Compression compared to CESSB

[Bob McGraw K4TAX]

I have studied and measured both the Compression algorithm and, as a 
separate project, the ALC operation using my K3S.  It is clear the ALC 
system is very different as implemented in the K3S from other radios in 
as much as there is some gain ranging which occurs below the 5th bar of 
ALC indication.  After and above the 5th bar the system goes into a gain 
reduction scheme, somewhat typical of other ALC systems.  One key to ALC 
systems which make them very different is the attack time the release 
time and the compression/limiting ratio, meaning input signal change vs. 
output signal change.  All in all, the K3S system is very clever and 
much like audio processing as used in commercial broadcast 
applications.  Perhaps this accounts for the excellent results.


This is clear for those that work digital modes and are instructed to 
adjust the input level to the point the 5th bar is flickering when using 
the K3S.  Clearly, until one understands this, most revert to 
instructions found with digital programs, digital interfaces and other 
radios which clearly say "adjust to the point below ALC action".  In the 
case of the K3s, there is really no ALC action below the 5th bar.  In 
fact the value as show on the ALC scale below the 5th bar is more of a 
VU type indication with some degree of level expansion.


As to CESSB, the articles in QEX and QST February are very interesting 
and enlightening.   It is interesting note that the CESSB methodology 
increases the average power by a factor of some 2.5.  Of course the 
major advantage is not only increased average power output but greatly 
reduced distortion as a result of the method employed.


It will be very interesting to see how all this plays out in regard to 
implementation in future radio designs.

Re: [Elecraft] KX3 feature request: mAh counter

[Al Duncan]

Our club group recently bought a number of inexpensive volt/amp digital
meters on eBay to use in an APP distribution box project and we found the
same problem - the current is sensed in the negative/ground lead. So any
other ground connections from the rig end up in parallel with it.
I have batteries in my KX3 but always use a gel cell for power when portable
camping etc.; I also use a buck/boost regulator that supplies a constant
14VDC to the KX3 from the battery, since both ground and hot leads from the
battery are isolated from ground, the Watt's Up works well. Sometimes I add
three 10W solar panels and a charge controller to help keep the battery
topped up.

Yes and no. All versions of this product I've seen read current in the 
NEGATIVE lead. That's fine of the unit is in series with the battery, 
but it will yield VERY WRONG data if inserted in series with equipment 
in a station.

At the Visalia DX Convention last spring, I found the Hamsource EZ Meter 
II, which reads current in the POSITIVE lead, and yields good data for 
individual equipment items in a station.

It does NOT read Ah.

powered down or open circuit condition should result in defined states for,
particularly control signals (off), in practice it means that real world
receivers will also handle high speed signals which are strictly positive.

Consequently levels of +5 and 0 volts will, in most normal cases, work,
although they are out of specification.

ITU-T V.28 is generally aligned with the electrical characteristics of
EIA232, but has the advantage that the document is available for free
download.

Re: [Elecraft] K2 raspy side tone

[Phil Wheeler]

I'll second that. I have K2 #380 and changing the 
AF pot wiring a couple of years ago cured all of 
that AF gain scratchiness.

Jacob,

If the AF Gain is scratchy when turned, the best cure is to replace it.  Those small pots 
are sealed, and I doubt that you could get any DeOxit into the body of the control.  Even 
if you can get some inside the pot, the "cure" will not be long lasting, you 
will eventually have to replace the pot, so 'bite the bullet' and do it now.
The carbon (or other material) that forms the resistive layer over which the 
wiper rides can become pitted and work with extended use - there is no way to 
fix that other than replacement.

Hello;
I have an older K2 that has developed a raspy, scratchy sounding CW note on 
receive. All bands affected. The transmit sidetone is clean as a whistle. 
Headphones or external sparker are the same. Seems like there is some popping 
and scratching when I bump or play with the AF gain control. Could that be it? 
And I'm thinking of spraying with DeOxit contact cleaner. Is that OK? Thanks!

[Elecraft] Feature Suggestion - P3 option to function as bigger K3 display

[Barry N1EU]

I'm not sure if this has ever been suggested or discussed before.

Many of us have long loved the K3 but bemoaned its diminuitive display real
estate.  If this isn't true of you, please read no further.

Why not add an option to the P3 so that the user can use a section of the
P3 screen to display many useful K3 settings that are normally hidden from
view and would otherwise require at least one or two button presses to view
individually?

Here's a partial list of settings I'd dearly love to see displayed:

Subrx ANT

Subrx PRE

MIC

COMP

PWR

DELAY

MON

PITCH

BW

LO

HI

TX ESSB ON/OFF and BW

RX/TX EQ levels shown with better graphics



Perhaps flexibility could be provided for users to select their own group
of settings to be displayed, how much P3 screen real estate to devote (in
the case of SVGA users, perhaps they optionally devote the entire P3
screen).  Also, users could toggle it on/off and return back to classic P3
display as desired.


I was thinking that something like this plus NK7Z's Genovation macro
generator would turn the K3/K3S/P3 into my dream machine  ;-)


Thoughts?

Re: [Elecraft] Genovation Keypad on teh K3/P3, solved

[David Cole]

The spreadsheet that comes with the Genovation keypad has keys on it
with the same aspect ratio as the physical keys.  This is so one can add
labels.  I added color, and labels, then printed and cut the paper to
fit under the keycaps.  The keypad comes with a keycap remover, so this
has been a godsend in labeling.

[Elecraft] K3 Compression compared to CESSB

[Robert Sands]

Given the recent article in QST explaining CESSB I looked for some detail
about the compression algorithm of the K3 but found nothing explaining how
it works.It is the most effective processing I have ever used and appears
to double the transmit power. So perhaps it is a version of CESSB or
efficient enough to be left alone as is. Perhaps I missed some discussion
on this.Is there a published explanation of the compression algorithm? (not
in Fred's book, I looked and checked with him)

Hi Barry.  I had one of these...worked great.  If I recall it comes with a pre

blanks as well.

Hi Fred,

I have no reason to believe it won't work with the KX3, or K3S either, I
just don't have one of the new K3S rigs, so I can't test it...  Hence
why I only talk about the K3.  

Now if Elecraft would just give me a K3S, I'd be happy to test it...  :)

Please do feel free to include the links to the setup.  Here is the a
direct link, which should never change.

I will be updating it often with new macros.  I already have most filled

[Elecraft] KX3 Feature Request

[Myron Schaffer]

I know this may be a nit but it would be neat if the VFO B knob would increment 
without rounding off the frequency. For instance, I participate in the foxhunts 
and find the fox. Then I use the DW SUB function and dial in the fox with the 
VFO A knob. If I use the VFO B knob it rounds off the decimal place and 
overshoots the target freq. If it were set to just increment of 1.0 I would 
land exactly where I want but it rounds off the freq and throws me out into 
left field.

Thanks.

Re: [Elecraft] Genovation Keypad on teh K3/P3, solved

[David Cole]

Hi,

It's not that difficult, most of the work is just programming the P3
macros into the P3 as Elecraft instructs you to do.  Which was harder to
do than prepping the Genovation, as I used an external keyboard on the
P3.  

Once the Keypad is updated, I just enter the triggers one time, hit the
download button on the keypad software, and I am done forever
programming the keypad.  

The keypad triggers the P3 to fire its macros, so you just program the
triggers in once, and on the P3 make sure they match.  If you want to
change macros, just change the P3 keeping the same trigger.  The
triggers are arbitrarily selected.  I used 1-z, 1-0, and F1-F12, one for
each key.  Then I just program the P3 to fire a macro on the appropriate
trigger.

The trick is in getting the triggers to match, and that is taken care of
by the chart you can download.

The write up makes it look a lot worse than it is because of the detail
level.  The entire process took about 3 minutes to prep the Genovation,
and the rest of the time was spent making macros on the P3.  

Once the Genovation is programmed I never program it again...  All it
does is trigger macros from the P3.

I must say, that after using the external keypad for a few hours on a

Re: [Elecraft] Long RS232 Runs - RS422

[David Woolley]

The +/- 3 volts levels are requirements on the driver, not the receiver. 
 In practice, receivers have quite a small hysteresis, and the 
threshold points are set to meet the requirements of a type 1 interface 
as defined in section 7 of ITU-T V.28.  Whilst the specified purpose of 
this is that a powered down or open circuit condition should result in 
defined states for, particularly control signals (off), in practice it 
means that real world receivers will also handle high speed signals 
which are strictly positive.


Consequently levels of +5 and 0 volts will, in most normal cases, work, 
although they are out of specification.


ITU-T V.28 is generally aligned with the electrical characteristics of 
EIA232, but has the advantage that the document is available for free 
download.

Re: [Elecraft] Genovation Keypad on teh K3/P3, solved

GREAT job Dave.  I'll bet this will work with the KX3/PX3 too.  I'd like to 
refer to it in the next editions of the K3S and KX3 books if that's OK with you.

Hello,
I now have a Genovation CP48USBHID keypad working on my P3/K3 feeding up
to 48 different macros to the K3 at a single button press.

See:
http://nk7z.net/adding-an-external-keypad-to-the-k3/

for the how to, and a download for the patch to the Genovation to allow
it to plug into the P3 and be recognized.

[Elecraft] DLY button question after beta 2.44 firmware installation

[Michael Blake]

After installing the latest KX3 beta firmware (2.44)  I was running through all 
of the option buttons to see if they still functioned correctly.  When I got to 
the DLY button my VOX Delay was still correctly set at 0.40 but was proceeded 
by the word “STOP”.  By this I mean that the DLY display read “STOP0.40”.

Has this always been true?  What do the characters “STOP” mean?  I found no 
reference in the manual and it has been months since I last changed this DLY 
value.

Subject: [Elecraft] Remote KAT500

Again, thanks to all.  To summarize for all who took the time to offer
information and suggestions:

1.  From an Elecraft engineer [who I happen to know quite well]:  The AUX
cable is probably not a good choice to extend.  In addition to voltage and
RFI issues, there are timing constraints on those circuits. 
  I can do what I need with RS-232.

2.  I should be able to make RS-232 work.  I personally know that many
so-called RS-232 drivers use +/-5 V rather than +/-12 V.  This is a problem
I can solve.

3.  Universal agreement on no connectors outside.  Almost universal
agreement on "no connectors penetrating the housing."  Almost universal
agreement on cable entrance glands of one type or another.

4.  Condensate drain(s) are a must.  There is universal agreement that water
(and apparently other things) runs downhill. :-)  I learned that changes in
inside vs outside pressure over the day will also initiate condensation [did
not understand how that works].

5.  Insectus Multileggus tend to be somewhat limited in our area due to hard
winter freezes and reduced summer precipitation, but I will need to keep
them out.  We have small bunnies [not jack rabbits] that abound [and chew]
around here, it appears that our backyard is immune right now but I will
protect the cable drip loops anyway.  I will personally congratulate any
gopher or mole that can dig through our caliche.

6.  Right now, I'm leaning toward a large enough PVC pipe, several inches
long and open at the bottom [except for critter control] for cable entrance,
condensate drain, and pressure equalization.  I'll probably put a light bulb
in the case.  There is universal agreement that I need common-mode chokes at
the ends and maybe along the cable runs inside the conduit.  Fortunately, I
know K9YC, I'll consult with him on those.

Thanks to all for all the information, advice, ideas, and guidance. 
I'll post occasionally as this plan progresses.

73,

Sounds like a cottage industry in the making. Sell/deliver the keypad in 
plug and play fashion along with 10 or 12 macros to be used as seeds and 
samples (for modification and copying). Thus allowing easy installation 
and learning how to do the macro stuff on the P3 (keypad already 
programmed with the single alpha/numeric names for the macros to be 
programmed in the P3).

Personally, I would pay for plug & play.

Re: [Elecraft] KX3 on 2 Meters

[Andrew Hebden]

Hi John,
I use the 2m module in my KX3 and am pleased with the performance. Having
said this I really don't have much to compare it against apart from my
FT897D. What I do find is that the noise floor goes way down I don't have to
listen to a load of white noise when digging out those weak signals.
I use it for our UKAC 2m contest on SSB along with a small (old) Microwave
Modules Linear running 10 watts output and regularly make 300mile+ contacts
when using my 9el yagi at 40feet with shack located about 3feet above sea
level. It is far better at handling strong signals than the FT897D. The sort
of strong signals I get are of sufficient strength to start the KX3 high
signal shutdown process. (I have 3 of the UK's leading contenders within 5
miles across open fields.)
On the whole I am really enjoying using it. Furthest DX so far on 10w is
south of France at about 800miles during a slight opening.
Problems encountered:
- There are a couple of internal "birdies" which are not too bad.
- With the gain well up I do notice the "zipper" noise when tuning the VFO.
There are notes about this on the Elecraft website.

I have a KX3 and am curious to hear from users that have the 2 meter module
installed how you find the performance with the various modes. Any good DX
with SSB or CW?
