Well said Don.

And I feel the very same way about my FT K2 (#8) as well.

[Elecraft] The MOJO explained

[stewart rolfe]

Fellow Elecrafters,

No black holes yet from the Large Hadron Collider at CERN in HB9 land but seems 
the first discovery may have been made. It's claimed by some that a new energy 
form has been found; it's called Elecrafticity.

Apparently it's a new type of wave particle in the Kth dimension and is all 
pervading. Cool...

Simon, is your K3 feeling heavier and looking smaller? Simonare you there??

[Elecraft] 3 rigs compared

[Charles Harpole]

First pass at USER evaluation of FT-9000d, K3, ORION 1.

Settings were as alike as possible, band had 5 signals from S-7 to S-1 (in 
QSO).  20m ssb.

Same speakers, same ant.

Sensitivity:  9=hiss was high pitched and somewhat irritating (no sig)
  with sig, hiss not discernable.

 3= most quiet with no sig, more base in audio.

  1=similar base, higher hiss than 3, but sigs above S-6 
sounded vy natural.

All three on vy weak sig could not discern any difference.

NR alone:   9= good result but slow processor (?) caused some "blasting" when 
NR knob turned.

   highest setting kills most hiss. Irritating when knob turned.

 3=  good result, vy vy small processor delay, highest setting kills 
most hiss.

  1= great result, vy vy small proc. delay, highest setting kills all 
hiss.

NB alone:  9=vy gud on ignition noise, kills all;  no effect on other noises 
all knob settings.

   3= IF "wide 7" gives some chop on sigs, otherwise good.

  DSP "T3-7" same chop.  Lower both settings-no effect on 
no signal condx.
   
  no automobile near by.

1= H only- no effect on no sig condx;  H + 9 gave same result, 
no car near.


"u Tune" 9=Absolutly great, kills many kinds of noise and BCI.  A "must 
have" feature!

 3 and 1 = no have.

Quiet idle (ant connected, no sigs.):  9, 3, 1=  all same,3 and 1 more 
bassy.

Controls:   9= Unequalled for controls of vast number on front panel... Built 
in Display etc.,

   great fun to use.  Bandscope great for this kind with 
jagged peaks from bottom

of the scale (like all of them now days).  Very useful.

 3= Bare bones with lots of multi function knobs, This one is 
not for the knob twiddler.

 1= Two huge tuning knobs good, but weak weak usefulness of 
band scope... mostly useless.

 strange sometimes Cut & BW & PBT interact (turn one 
affects the other in a bad way)

 sometimes does not do this.  AF is more base thus less 
hiss seems to be there.

Overall score:   9= Best base rig, super fun to play with, performance within 
others' range.

3= marginally better on sensitivity but too close to 
really call;  not enuf knobs.

1= dull looking, hard to love, but lots of info 
on-screen;

 Very flexible Ant and VFO A/B and Sub. 
handling.

Can I keep them all, please mom?

Re: [Elecraft] Illogical coding

[Brian Alsop]

Bob,

In fact, just pressing SPLIT should get you to the same condition as two 
A-B taps and pressing SPLIT.


Miss one of the three steps are you're transmitting on the DX frequency.

I just don't understand the logic.   It isn't if operating split is a 
rare occurrence.


Those few who want cross band or cross mode splits ought to have to do 
the extra taps.


I really hope Elecraft will fix this some day.   Other rigs have it right.

Of course there is the $600 solution

Starting with 1.87, two taps are needed - the first to copy the
frequency, and another to copy mode and filter settings. The result
can be the same as in your case if I go split but forget to tap A->B
twice. No rationale was given for the change, but from a ergonomics
standpoint I never understood why the most common use case was
complicated in this way.

through all the cal and setup routines and all was perfect. I was turning my 
attention to the bands and was looking to snag a new country on cw. I noticed 
that the station was listening up in frequency so I engaged a split on VFO B 
and set the frequency and tried to call but no action out of my key. I looked 
at the display and discovered that I was no longer in QSK only VOX so I hit the 
QSK button and VFO B came back and said N/A in the screen! I tried several 
times to engage QSK but no way was I going to get the K3 to key. Going back to 
XIT I was able to snag that guy but here is where it gets interesting. I called 
Elecraft and asked what was going on and Scott had no Idea but asked me what 
version of manual I had and discovered that I had an old version C that was 
over a year old! I downloaded the newest version of the manual and much to my 
surprise there was a note that is not in the earlier version about B SET that 
indicated it could be set up in a different mode! Sure enough that VFO had been 
set up for SSB and that was why I could not key the radio. Why on earth if you 
are in CW on VFO A and press split would you ever expect that  VFO B would ever 
default to anything but CW on VFO B!!! This in my opinion is completely 
illogical. Can anyone out there give me an explanation why I should be wrong on 
this account? I might have been upset if I didn't go back to XIT to solve the 
problem but I can just see in a contest situation where someone was unaware of 
this that sparks wouldn't fly. What say you guys!

Since I rarely work SSB this must be the reason the O II here is on the shelf
and the K3 rules the operating position here at N5GE.

[Raymond METZGER]

K2 # 5,636 still live and used alternatively with my K3.
Mainly, but not necessarily, for portable operation at other locations.
Running two rigs is better and safer than only one.
The K2 offers also the pleasure of building, modifying and tweaking well
beyond what's the K3 offers !
Will never sell my K2 !

Re: [Elecraft] Illogical coding

[Lyle Johnson]

In fact, just pressing SPLIT should get you to the same condition as two 
A-B taps and pressing SPLIT.


While cross-mode QSOs are not as common on HF as they are on 6 meters, 
such an implementation would make them extremely difficult.


The K3 is a complex radio and has its own personality.  After you spend 
some time with it, you'll probably get to know it quite well.



I really hope Elecraft will fix this some day.


The changes came about as a result of careful deliberation based on 
input from customers, followed by field testing and evaluation of that 
feedback.


We're listening!

I agree with Bob.  The "tap dance" for split is very prone to 
error.  I can't think of any other transceiver that requires 
two presses of the A->B button to store both mode and frequency.

Re: [Elecraft] Illogical coding

[dj7mgq]

The changes came about as a result of careful deliberation based on
input from customers, followed by field testing and evaluation of that
feedback.

We're listening!


Maybe this kind of behaviour ought to be configurable. Should this  
lead to a "built in menu overload", I, personally, wouldn't mind using  
an external tool. Once set, I doubt I would ever change something like  
this again.


BTW: I like the current solution...

If "u Tune" reduces noise, the receiver is suffering from intermod 
or "window AGC" issues.  Simply tightening the front end (a preselector) 
should not decrease the noise within the detector bandwidth.

RE: [Elecraft] Illogical coding

This two button push thing to copy all info to VFO B is the only thing that
I don't like about my K3.  I've had my K3 for a little over two months and I
still don't like this feature.  Why not make the two button thing an option.
Everything else has an option.  I agree with Joe.  I really hope Elecraft
will fix this some day.

The K3 is a complex radio and has its own personality.  After you spend some
time with it, you'll probably get to know it quite well.

The CW in SSB feature makes cross mode QSOs no different than 
a SSB QSO.  It is no problem to narrow the filters in SSB if 
necessary - even to the point of using a 500 Hz 1st IF filter 
as long as it is enabled in SSB.  

If a user insists on setting VFO B to a different mode, "B Set, 
Mode, B Set" is certainly adequate to "undo" any mode change 
caused by A -> B.

This is a good idea to have an external tool using the K3 computer interface to 
be able to set menus.  Depending on how the program is written, it would be 
nice to see all the parameters in a spreadsheet like venue...and then be able 
to change them through the utility.

I've "played" around with the commands for the K3 (just for my fun) and it 
seems this could be done with some coding expertise.  I do not like flipping 
through the menus...I get lost.

Just a good idea...a software tool for configuration of the K3's parameters.

I agree with Bob.  The "tap dance" for split is very prone to 
error.  I can't think of any other transceiver that requires 
two presses of the A->B button to store both mode and frequency.  


The K3 previously did copy mode (and other parameters) on the first tap. 
But some users felt that they would like to be able to choose whether to 
do this. The change added overall flexibility at the cost of an extra 
tap. Sure, it's a compromise, like all engineering and software design.


Someday perhaps we'll be able to define macros within the K3 (of course 
today it can be done in a rig control program). If I could define a 
macro for split, here is what I would do (in CW mode):


Split on
Subrx on
Copy freq and mode to subrx
Set subrx bandwidth to 1 kHz (leave main as is)
Move subrx up 2 kHz

[Elecraft] Illogical coding

[Phil & Debbie Salas]

"...Previously, a single tap of the A->B button copied frequency, mode and 
filter settings from VFO A to VFO B.  Starting with 1.87, two taps are 
needed - the first to copy the

frequency, and another to copy mode and filter settings"

I like it the way it is.  I normally have my sub-receiver set to a wider 
bandwidth than my main receiver, so I just want to feed frequency info to 
the sub-receiver.  Let's face it - how difficutl is it to tap twice?

RE: [Elecraft] Where have all the K2s Gone?

[Brian]

My K2 #5946 is still my favorite radio.  Although it has an intermittent
receive problem that it has had since I built it.  About half of the time it
hears great, better than any of my other radios.   And the other half of the
time the signal is severely attenuated.  It seems worse on the bands that
use USB.  Usually when I turn it on for the day is when the problem shows up
and after a while I will hear it get better and the s-meter jumps up to
where is should be.  Sometimes it never gets better.  Once the problem goes
away for the day, it usually doesn't come back until I shut the radio down
and let it cool overnight.  I have tried several times to find the problem
but have been unsuccessful.

Sounds a lot like an unsoldered or poorly soldered connection. You could 
just go over the RF board and reheat all of the solder joints, adding a 
bit of fresh solder (mostly for the flux).


It could be an intermittent component, but it's more likely a solder joint.

If it will stay broken long enough to use the signal tracing technique 
described at




you may be able to find it that way.

[Elecraft] K3 Firmware loading errors with VOX on

[Tony Fegan VE3QF]

Hi K3 Firmware/software support gurus,

	I upgraded from firmware version 2.34 to 2.38. I had left the VOX on 
and sometime during the load I put my coffee cup down on the operating 
table and the VOX tripped. The firmware load continued with no error 
message. I assumed (I know!) that all was OK until I got on a local 10M 
net and was told that I was transmitting 100Hz high but audio was good. 
I later found that receive on 20M was 100Hz high but transmit was OK. 
That is all I checked before remembering the VOX trip during firmware 
load. I reloaded the firmware with VOX off and all seems well.


	I thought that I should do a test to try and repeat the error. It seems 
that VOX is only active during the FPF part of the load and it is easy 
to make it fail but I always get an error message.


	It may be the cause of some odd problems. Maybe it is possible to kill 
VOX during FPF load as happens during MCU and DSP load.


Hope this helps somebody

Re: [Elecraft] Where have all the K2s Gone?

[TF3KX]

I agree.  My loaded QRP K2 is the only rig I am sure I will keep for the rest
of my days (just turned 50 this week, so I'm looking forward to quite many
more to come...).

The reason it's the definite keeper:

- All-in-one, just like the Swiss army knife:  All bands and modes, int.
battery, tuner, anything you wish.
- Small and portable
- Excellent performance
- Self-built, and therefore I can feel confident modifying and fixing when
needed.

It has started to occur to me, however, how long the individual components
for the K2 will be available in the years to come.  Perhaps I should start
stockpiling as they run out of production...?

Re: [Elecraft] Illogical coding

[Bill W5WVO]

Agreed, this would be an easily fixed "bug" -- just include the
A>B[all] function as part of the results of pressing SPLIT.

However, as a 6-meter operator, I vote for retaining the current
behavior as-is, due to the common occurrence of split-mode (as
opposed to split-frequency) QSOs. You could make the automatic
behavior you desire be a configuration option -- "SPLIT invokes
A>B[all]" or something like that. I can see where an HF DXer would
like it to work that way. However, for my purposes on VHF, I
prefer to have all this stuff manually under my control, as it is
now. Please don't do away with this more flexible capability
altogether!

And as an ancillary comment, I hope the fix for the SSB/CW VFO
offset issue is coming up in the queue Real Soon Now. Been waiting
a long time. :-)

RE: [Elecraft] Illogical coding

[Bob Serwy]

Why couldn't this be a configuration setting?  The A>B can be set like it is
now (single tap and if needed a second tap)or a single tap would be an
A>B[all]. If this is something you would like to change on a regular basis,
then give the ability to use a PF key to toggle the selection.

Dave,

Amidon has that information, and it is printed in th ARRL Handbook.
OR - you can download mini-Ring Core calculator (free compliments of 
DL5SWB) from http://www.dl5swb.de/html/mini_ring_core_calculator.htm and 
it will not only give you that information, but do many other 
calculation for inductors, resonance, and tuned circuits.

I also suggest that you study the material on ferrites in 
http://audiosystemsgroup.com/RFI-Ham.pdf  

The discussion of ferrites in this tutorial is considerably more 
advanced than what's on the Amidon site or in ARRL publications, and 
should give you a much better understanding of ferrites, how they work, 
and how to use them. Tne most important thing to understand is that 
permeability of ferrites is not a single number -- it varies (a LOT) 
with frequency. The commonly published number is the LOW FREQUENCY 
permeability. The second most important thing to realize is that 
ferrites are pure inductors ONLY at low frequencies. As frequency 
increases, resistance and capacitance become increasingly important, 
and at high frequencies R and C dominate (to the extent that there's no 
L!). When we use ferrites to wind coils for transceivers, we mostly 
care about L. When we use ferrites to suppress RFI, we only want R. 

Most (all?) ferrite cores sold to hams by Amidon and others are 
actually made by Fair-Rite, a very good US company based in NY State. 
They publish an excellent catalog that includes extensive data on all 
of their products.

RE: [Elecraft] Illogical coding

Vic,

I'm aware of that.  I went thorough the change and am saying I 
prefer the old way.  If one is storing VOF A data to VFO B the 
most likely desired outcome is to change frequency and mode.  

> But some users felt that they would like to be able to choose

If a small group of users prefer not to change mode with frequency 
make it an option or let them use "B Set, Mode, B set."  Otherwise, 
make the behavior context sensitive - e.g., if already in split 
or dual use the current behavior, if not split use the old form 
(set frequency and mode).  

> Sure, it's a compromise, like all engineering and software design.

The extra tap is an ergonomic trap for the majority of users not 
schooled in "the Elecraft way" and a recipe for "UP LID" if the 
second tap is too fast, too slow or too light. 

As far as the cross mode stuff ... the "CW in SSB" capability is 
ideal for that.  It does not require mode shifting and avoids the 
"frequency shift" when going from SSB to CW (stay is SSB and 
narrow the filters).

[Elecraft] K3: A>B two-step (was "illogical coding")

[DOUGLAS ZWIEBEL]

I have to agree that this change was not so smart (maybe clever, but not smart).

While I admit that I never thought about the guys who "do this
commonly" (I think they are the VHF types), I do think that this mod
was a case of being over-zealous in the "we can do it" mentality as
compared to the "what will the VAST MAJORITY" of users want?  I bet
that this isn't even close to an 80/20 rule.

IMHO, the VAST MAJORITY of K3 owners who use A>B are HF types who want
EVERYTHING copied.  And while "how much longer does it take to tap
twice" may be true, it is "more" true that this change was made to
benefit the few at the expense of the many - a violation of many
business and operational principles.

I am a strong advocate for letting the USER decide which method (one
tap vs two) and that the selection should be implemented via a MENU
item (if possible).  Personally, I have not and will never use just
"one tap" (allowing for the times that it worked "the right way" prior
to the change).

I relinquish the soapbox

[Elecraft] Re: K3: A>B two-step (was "illogical coding")

[wayne burdick]

Doug,

There was plenty of logic behind it, but in hindsight it might not 
sense for all users. (It did meet with the approval of our 20 field 
testers.)


The change was motivated by the sub receiver. Here's one example:

Suppose you're using SPLIT, listening to a weak DX station on the main 
RX (in a very narrow bandwidth with preamp on), while tuning for a 
clear spot with the sub RX (using a wider bandwidth and preamp off). 
With one tap of A>B you can move VFO B back to the starting point and 
work your way up again. If this also copied VFO A's filter and preamp 
settings (etc.) to VFO B, you'd have to set them up all over again.


But I'll be happy to sit back and listen to arguments pro and con. If 
it looks like a lot of operators would prefer to copy everything with 
one tap, I could add a menu entry. If no one argues in favor of two-tap 
(including the field testers), I could change it outright. I'm easy  :)


Thanks for your input.

Re: [Elecraft] HELP! Permeability of Ferrite Cores...

[Jack Smith]

One small addition to Jim's observations.

Fair-Rite changed the chemistry of its Type 43 material a couple years 
ago. The new Type 43 material has much better Q (lower loss) compared 
with the old version, by a factor of more than 10:1 at some frequencies. 
There was also a very small change in the quoted permeability at low 
frequency, from 850 in the old to 800 in the new, if I recall correctly. 
Z remains relatively unchanged from old to new, but the R+jX components 
of Z are different, with more jX and less R at lower frequencies.


This chemistry change is important if (a) you have an old core in the 
junkbox and (b) you are planning on using it in a tuned application or a 
filter. Otherwise, no.


I'm working on an article for QEX on ferrite cored inductors and 
transformers but it's still some distance from being ready for submission.

I also suggest that you study the material on ferrites in 
http://audiosystemsgroup.com/RFI-Ham.pdf  

The discussion of ferrites in this tutorial is considerably more 
advanced than what's on the Amidon site or in ARRL publications, and 
should give you a much better understanding of ferrites, how they work, 
and how to use them. Tne most important thing to understand is that 
permeability of ferrites is not a single number -- it varies (a LOT) 
with frequency. The commonly published number is the LOW FREQUENCY 
permeability. The second most important thing to realize is that 
ferrites are pure inductors ONLY at low frequencies. As frequency 
increases, resistance and capacitance become increasingly important, 
and at high frequencies R and C dominate (to the extent that there's no 
L!). When we use ferrites to wind coils for transceivers, we mostly 
care about L. When we use ferrites to suppress RFI, we only want R. 

Most (all?) ferrite cores sold to hams by Amidon and others are 
actually made by Fair-Rite, a very good US company based in NY State. 
They publish an excellent catalog that includes extensive data on all 
of their products.

High cost shipping on low cost articles (was: [Elecraft] K3 #1140 For Sale on ebay)

And the effect of Ebay... But it is a real problem for us overseas people.
Many firms will not ship abroad at all and others insist on using expensive
couriers, even for items only costing a few $. My recent problem trying to
get a 15-way cable for example. It would cost $10 for the cable and $60 to
ship it, and that is before customs charges.


In that example, shipping in a jiffy bag would have avoided the customs 
and customs clearance charges as well, as you are currently allowed GBP 
18 including shipping costs (I believe this is going up to around GBP 
100 at the end of the year).


Incidentally, for someone in the UK, I have found that Germany is a good 
place to source accessories.  UK vendors seem not to advertise small 
accessories, or ones for older models.  The German vendors don't seem to 
fall into the everything gets courier prices trap.  The one downside is 
that some of them do not take plastic, but expect a Euros bank transfer. 
 That immediately adds GBP 15 to the cost.  I did find one that had the 
parts I wanted and did take plastic/Paypal.  There are no customs duties 
for imports, to the UK, from Germany.  You do have to pay VAT, but that 
is paid as part of the price to the vendor.


I believe Elecraft will ship small items by cheap methods, but it would 
help if they actually provided details on the web site, even though they 
may well not charge the international courier rates for them.  I'm 
reluctant to consider any of the small kits on add ons because I don't 
know the shipping cost (I'm also waiting for the customs exemption 
limits to rise).

[Elecraft] KX-1 Ferrite question - background info for the request..

[Dave G.]

For those that might be ibnterested

FWIW - Using a KX-1+KXAT1, I'm trying to find a way to adapt the 
(standard?) 
~26ft wire with 16ft counterpoise to work on 3.55Mhz...

Here's what I've been thinking...

I was initially considering modding the internal KAT1 toroids. The trick 
there would be to get the three toroids to cover the whole KX-1 range.. the 
probable outcome would not being able to get below an SWRof 2:1 or 3:1 
on many frequencies with the existing antennae
.
But I remember (when I was G3UTY)  being mobile in London, UK  on 
160M with 10W. We used center-loaded 
8ft whips. Very large inefficient coils but we still managed to work the 
european continent...

So here's the situation, as I see it, looking at efficiensy and current/voltage 
distribution;  and bearing in mind that, typically, most /P is done with 25-
40ft of wire.

1) End loading with L+C is probably out due to exremely high voltages and 
also that's the end needed to hang the wire in the trees/fishing rod/etc... it 
is 
still a possibilty.

2) Center loading with L only would be the next best. Middle range voltages 
and current but it would mean hanging a small weight in the middle of a 
length of (usually) very light wire. Might not be a practical solution..

3) Bottom loading which, in this case, is at the KX1 BNC connector
This gives the L minimum voltage with high current but also has the lowest 
radiation efficiency. Hanging an extra bit of weight on the BNC connector 
might not be such a good idea! So perhaps a short length of RG174 which 
connects to the L (or an LC) circuit would be the best idea but /P operators 
might 
not appreciate carring an extra bit of wire in their Go pack!

4) Adding a coil to the counterpoise... in effect making the KX-1 directly 
feeding an OCF  needs more thought  ;^-|

Any opinions?? Thoughts? Suggestion?? 
Ooops, better careful answering the latter

The K3 previously did copy mode (and other parameters) on the

I'm aware of that.  I went thorough the change and am saying I 
prefer the old way.  If one is storing VOF A data to VFO B the 
most likely desired outcome is to change frequency and mode.  


Mode is not an issue for me, since I operate 99.999% CW. But along with 
mode come the DSP parameters (bandwidth and center frequency). And I 
often *don't* want to copy these, because I like to use a wider 
bandwidth to listen to the pileup than to the DX.


If a small group of users prefer not to change mode with frequency 
make it an option or let them use "B Set, Mode, B set."  Otherwise, 
make the behavior context sensitive - e.g., if already in split 
or dual use the current behavior, if not split use the old form 
(set frequency and mode).  


So what I would have to do is A->B, BSET, twist bandwidth knob, BSET (to 
exit BSET mode). No thanks!


The extra tap is an ergonomic trap for the majority of users not 
schooled in "the Elecraft way" and a recipe for "UP LID" if the 
second tap is too fast, too slow or too light. 


'Too fast' is not a problem. 'Too slow' means waiting (I think) two 
seconds, which is an eternity. And 'too light' is very hard to do with 
the K3's buttons.


I think part of the issue is that the K3 is different from what one is 
familiar with, so it takes some getting used to. This in itself isn't a 
problem.

On the other hand, sometimes I want them the same, and I can chose just

RE: [Elecraft] Illogical coding

[Ed Muns]

In all my operating, I want the frequency and mode to transfer, so doing
this with one button tap is ideal.  This is the way other radios work.

However, there are other use cases where only the frequency transfer is
desired and the current UI addresses that.  Even as a contester concerned
with minimizing UI actions, I'm not greatly hampered by having to tap A>B
twice ... the hardest part is remembering to do so.

How about making it a choice? I can see times I would like it one way or the

There was plenty of logic behind it, but in hindsight it might not 
sense for all users. (It did meet with the approval of our 20 field 
testers.)

The change was motivated by the sub receiver. Here's one example:

Suppose you're using SPLIT, listening to a weak DX station on the main 
RX (in a very narrow bandwidth with preamp on), while tuning for a 
clear spot with the sub RX (using a wider bandwidth and preamp off). 
With one tap of A>B you can move VFO B back to the starting point and

Re: [Elecraft] K3: A>B two-step (was "illogical coding")

[Brendan Minish]

In the beginning I hated it then I was undecided for a while, now I like
it! at this stage I am used to it and the double tap is very quick to
do.

With the sub RX in use for Dx chasing / Split it's great the way it is.
with no sub installed it makes less sense.

Give us a menu item, perhaps implement a second layer to the config menu
for all the UI things that people will rarely wish to change (but are
going to ask elecraft for anyway!) to prevent the main config menu
getting too cluttered. Icing on the cake would be the ability to edit
these settings from the K3 utility which could then be used to manage
'user profiles'  

Ohh and scrap locking VFOB in linked mode please !

My vote is for the option to set the preferred use of the split single 
tap.  Eventually.

I prefer the split capability one button tap for HF transfer all.
The cross mode capability for UHF even HF is a desirable option.
I agree that I get in trouble on HF remembering the double tap need.

Re: [Elecraft] Re: K3: A>B two-step (was "illogical coding")

[Don Wilhelm]

Wayne,

The two-tap operation makes a lot of sense for those who have the 
sub-receiver installed, because for other than diversity receive, one 
would not necessarily want to change the filter settings when doing an 
A>B copy.  VHF ops would likely also not want to change the mode.
So for the benefit of those with the KRX3, I would think it should be 
left as it is now.
BUT, for those without the sub-rx installed, the single tap does 
everything operation is probably more appropriate.


Is there any wisdom in making the operation dependent on the sub-rx?  If 
not, a menu item would be in order to satisfy the tastes of different 
users.  There are good reasons on each side.

[Elecraft] K3: A>B two-step (was "illogical coding")

[David and Dianne on Comcast]

Hi Wayne and All,

I'm an HF Dx'er who thinks that the VFO A to VFO B 'two tap' misses the 
mark for me. I vote to make it a program option, operator selectable.


More over I also would like to see a 'quick split function" ala ICOM 
where pressing the split button (with the sub receiver installed or 
not?) enters all the VFO A info in the VFO B but also with and 
pre-determined VFO B offset per mode such a +5 KHz for SSB and +2 KHz 
for CW.


Something like this was on my 775, Pro II and III and was extremely 
convenient for getting into the pile up fray effectively before many others.


Working 100W with only wire and a DXCC score of 342 seems to prove me 
out IMO.  ;-)


73 and tnx for listening!

is not desirable.  I would like the option for the single tap eventually.


My apology for cluttering the reflector by including a previous message 
in my last message.

Re: [Elecraft] KX-1 Ferrite question - background info for the request..

[Jack Smith]

In the 2-4 MHz band, if one absolutely must use a ferrite core for some 
reason or other, Fair-Rite 61 material would be a  reasonable choice. 
You might expect a Q in the 150 range, depending on inductance, wire 
size, number turns, etc. Type 43 Material at that frequency would make 
an excellent dummy load, and that's said with only very small exaggeration.


Powdered iron is a much better choice for this application in many 
respects, including temperature stability, Q, less chance of 
irreversible damage, etc.


Air wound inductors are even better but size is obviously a 
consideration. With either ferrite or powdered iron, the larger the core 
the better off you'll be when used for antenna matching or inductive 
loading.

For those that might be ibnterested

FWIW - Using a KX-1+KXAT1, I'm trying to find a way to adapt the 
(standard?) 
~26ft wire with 16ft counterpoise to work on 3.55Mhz...


Here's what I've been thinking...

I was initially considering modding the internal KAT1 toroids. The trick 
there would be to get the three toroids to cover the whole KX-1 range.. the 
probable outcome would not being able to get below an SWRof 2:1 or 3:1 
on many frequencies with the existing antennae

.
But I remember (when I was G3UTY)  being mobile in London, UK  on 
160M with 10W. We used center-loaded 
8ft whips. Very large inefficient coils but we still managed to work the 
european continent...


So here's the situation, as I see it, looking at efficiensy and current/voltage 
distribution;  and bearing in mind that, typically, most /P is done with 25-

40ft of wire.

1) End loading with L+C is probably out due to exremely high voltages and 
also that's the end needed to hang the wire in the trees/fishing rod/etc... it is 
still a possibilty.


2) Center loading with L only would be the next best. Middle range voltages 
and current but it would mean hanging a small weight in the middle of a 
length of (usually) very light wire. Might not be a practical solution..


3) Bottom loading which, in this case, is at the KX1 BNC connector
This gives the L minimum voltage with high current but also has the lowest 
radiation efficiency. Hanging an extra bit of weight on the BNC connector 
might not be such a good idea! So perhaps a short length of RG174 which 
connects to the L (or an LC) circuit would be the best idea but /P operators 
might 
not appreciate carring an extra bit of wire in their Go pack!


4) Adding a coil to the counterpoise... in effect making the KX-1 directly 
feeding an OCF  needs more thought  ;^-|


Any opinions?? Thoughts? Suggestion?? 
Ooops, better careful answering the latter

[Elecraft] K3 KRX3

[Mike Harris]

G'day,

#345 now has two ears.  Installation, including the R91 modification, went 
without drama.

Initially I had an ERR DSE result from the 2nd VCO calibration operation. 
Reloading the DSP2 firmware fixed that.  The problem just might have been 
my own making because I forgot to turn the radio off and back on after 
enabling the sub RX in CONFIG.  The K3 utility was showing the DSP2 
firmware as version 00.00 before the reload.

Another surprise was the clock time was advanced about five and a half 
hours and the date was back to the big bang 00:00:00, also the K3 utility 
didn't reset the RS232 port back to 4800.  I only noticed this when there 
was no communication with Logger32.

What would be useful is a current list of what configuration items are 
automatically common to the two receivers.  This would save wondering if 
things like the RX equaliser needed copying to the SUB RX, AGC settings 
etc.

Looking forward to the audio mixer, not sure I like the RX1 left ear, RX2 
right ear business.

My 2K7 roofing filters have a 40Hz off-set difference. I did ask if one 
the same as that I already had could have been supplied, no luck. 
Enabling the SUB and A>B and locking the VFOs produced a very deep beat in 
the audio about 1-2Hz.  Will have a fiddle with the filter off-set +20Hz 
and -20Hz respectively to hear what happens.

So, back on with the training wheels.

Regards,

Mike VP8NO

It doesn't matter whether you have a subrx or not. You still use VFO B 
to scan a pileup -- you just can't hear both QRGs at the same time.

The sub-rx document says your loose 3db of signal in the main rx when
switching in the sub rx when sharing the main antenna.  
For really weak ones, you'll probably want to have the sub-rx off unless you
have a separate antenna for the sub-rx.

The signal (including received noise) from the antenna is reduced by 3 
dB when sharing.  If you can still hear band noise from the antenna, you 
are only losing 3 dB overall gain, not S/N.


If AGC is activated, it is reducing gain so the splitter loss is 
inconsequential.


Only if the band is so quiet that you don't hear band noise when you 
connect the antenna do you risk degrading S/N by up to 3 dB.

I think the issue is specifically copying mode along with the 
frequency.  

To me, if KRX3 is not installed, copy everything since the receive 
parameters are not important on VFO B (no receive).  I would find 
it distracting to have antenna/filter/etc. change as I pressed 
the A/B or REV buttons.  If a KRX3 is installed but dual receive, 
or split operation is not selected copy everything (one can assume 
the tap means "configure everything") ... if dual receive or split 
is selected, copy only frequency/mode on the first tap and copy 
filter/preamp/attenuator/receive antenna/etc. on the second tap.  

In general, I think mode should be copied along with frequency. 
With the "CW in SSB" capability, I can't see a situation where 
the user would not want VFO B in the same mode as VFO A

Wayne,


Suppose you're using SPLIT, listening to a weak DX station on
the main RX (in a very narrow bandwidth with preamp on), while
tuning for a clear spot with the sub RX (using a wider bandwidth
and preamp off).  With one tap of A>B you can move VFO B back to
the starting point and work your way up again. If this also copied
VFO A's filter and preamp settings (etc.) to VFO B, you'd have to
set them up all over again.


I think the issue is specifically copying mode along with the
frequency.

To me, if KRX3 is not installed, copy everything since the receive
parameters are not important on VFO B (no receive).  I would find
it distracting to have antenna/filter/etc. change as I pressed
the A/B or REV buttons.  If a KRX3 is installed but dual receive,
or split operation is not selected copy everything (one can assume
the tap means "configure everything") ... if dual receive or split
is selected, copy only frequency/mode on the first tap and copy
filter/preamp/attenuator/receive antenna/etc. on the second tap.

In general, I think mode should be copied along with frequency.

Doug,

There was plenty of logic behind it, but in hindsight it might not
sense for all users. (It did meet with the approval of our 20 field
testers.)

The change was motivated by the sub receiver. Here's one example:

Suppose you're using SPLIT, listening to a weak DX station on
the main
RX (in a very narrow bandwidth with preamp on), while tuning for a
clear spot with the sub RX (using a wider bandwidth and preamp off).
With one tap of A>B you can move VFO B back to the starting point and
work your way up again. If this also copied VFO A's filter and preamp
settings (etc.) to VFO B, you'd have to set them up all over again.

But I'll be happy to sit back and listen to arguments pro and con. If
it looks like a lot of operators would prefer to copy everything with
one tap, I could add a menu entry. If no one argues in favor
of two-tap
(including the field testers), I could change it outright.
I'm easy  :)

Thanks for your input.

Re: [Elecraft] OT - PC Oscilliscope Performance

[Don Wilhelm]

Mike,

For that price, one could do better with a used Tektronics analog 
'scope.  Check with Bob Garcia (Mr. Scope) to see what he has available 
([EMAIL PROTECTED]) - you may be surprised at what you can obtain 
from him.  I speak only as a satisfied customer of Bob's - he is a real 
gentleman to do business with.  I believe he is a retired Tek repair 
type and usually has several Tek 'scopes available for sale.  He can be 
found at hamfests in the SouthEastern US.


Specificlly responding to your quesion:
The 100 MHz rating is good for most HF use, but for most ham purposes, 
one does not need the digital storage features.  Remember that the 
probes must also have the frequency rating of the 'scope or greater - 
the lowest common denominator is the frequency limit.  The digital 
storage qualities are nice when investigating digital circuits or power 
supply transient responses, but are seldom used for normal ham purposes, 
in most cases, one would want a real time display.  The most common use 
of a 'scope for ham radio troubleshooting is to measure RF voltages.  
Yes, my 200 MHz  Tek 475 'scope has dual vertiacal channels and delayed 
sweep, but most of the time is is used as a single channel 'scope with 
normal sweep.  Only investigations of delay parameters and the relative 
timing of digital signals require the use of the delayed sweep and both 
vertical channels.


Bottom line - if you are into digital stuff, this 'scope may be a 
bargain, but for most ham radio related purposes, one can save a lot of 
money with an older Tek 'scope (and HP too).


73,
Don W3FPR

This is working great.  I received my new AT-Auto tuner and configured it for

Hi Greg. I replied to your Elecraft post about AT-Auto and suggested you 
try LP-Bridge. I used Nabble for the first time, so I don't know if the 
post got to you, or you just figured it out. AT-Auto and SteppIR are two 
of the reasons I added the Output ports to LP-Bridge.

Not true. The two VFOs can be set with different bandwidths (etc.) and 
then when you hold REV or tap A/B, all the parameters change. This is 
how you work a pileup (at least, this is how I did it) when you do not 
have a subreceiver.

I am finding a need for a mode indicator on screen

in the heat of battle, or just being sleepy, it is too

Re: [Elecraft] Re: K3: A>B two-step (was "illogical coding")

[Jan Erik Holm]

My vote is for a single tap however what you say below also makes sens.
However if it´s possible to have a choice it sounds like the best
solution.

In a situation when you have no 2:nd RX IMO one tap would be prefered
however when you also have a 2:nd RX I can see the point with 2 taps.

The change was motivated by the sub receiver. Here's one example:

Suppose you're using SPLIT, listening to a weak DX station on the main 
RX (in a very narrow bandwidth with preamp on), while tuning for a clear 
spot with the sub RX (using a wider bandwidth and preamp off). With one 
tap of A>B you can move VFO B back to the starting point and work your
