Re: [Elecraft] Mouse-n-Click QSY (was P3 product suggestion)

[n9tf]

Good Stuff Joe. In addition to what you have suggested and done, the other 
thing I would like to be able to do is QSY the XIT frequency offset instead of 
markers A and B moving the VFO. This would be great when working a CW DX 
station working split usually up in a 1-5Khz window. For a QSK span within the 
10Khz span range I usually just us the XIT rather than going into split mode 
with VFO A and B. Not sure that is easily doable though currently since marker 
A and B can only move the VFOs and not XIT frequency. Guess that might be an 
additional firmware mod. Maybe a function command in the P3 to switch markers 
from moving VFO freq to activate moving XIT freq would need to be added? I 
already have PF1 and PF2 programed to turn on XIT and move +1Khz (PF1) and 
+5Khz (PF2). Being able to quickly QSY the XIT with a mouse would be an 
advantage.

Let's assume Paul Saffren delivers Mouse-n-Click QSY support with the next P3 
/ PX3 firmware release. What else would you like the mouse to do other than 
QSY the rig's VFO frequency? 

I demonstrated Mouse-n-Click QSY with an Elecraft PX3 and KX3 almost 18 
months ago, 

https://www.youtube.com/watch?v=D32PbJY60Uk 

http://www.wickedstone.com/KF5WBO/Mouse-n-ClickQSY.pdf 

I use the mouse to control marker A (or marker B). Tapping the left mouse 
button, QSY's the KX3's VFO A frequency to the marker A frequency. 
Optionally, tapping the left mouse button also sends an “auto 
spot” command to the KX3 (i.e., automatic zero beating). I found this to be 
very effective with PSK. With a little practice, you can Mouse-n-Click 
quickly. You just need to position the marker within the general vicinity 
of your target. The auto spot command takes care of the rest. It's like 
shooting fish in a barrel. 

If I *hold* (rather than tap) the left mouse button and move the mouse right 
and left, the marker A frequency *and* the KX3's VFO A frequency are 
increased and decreased in one Hertz increments, respectively (i.e., manual 
zero beating). You'd have to gauge for yourself how this compares to moving 
your hand between the mouse and the rig's VFO knob. 

If I hold the middle mouse button (wheel) and move the mouse up and down, 
the span is decreased and increased between 2, 5, 10, 20, 50, 100 and 200 
kHz, respectively. I'm effectively zooming in and out. Obviously, a better 
user experience would involve directly controlling the span using the mouse 
wheel without the need to hold the middle mouse button (wheel) or move the 
mouse. This would require a little more firmware. 

I also demonstrated the ability to execute all of the PX3 tap and hold 
functions using a mouse. If I tap the right mouse button over a switch, the 
Tap function associated with the switch is executed. If I hold 
the right mouse button over a switch for longer than 500 ms, the Hold 
function associated with the switch is executed. For example, if you click 
the right mouse button over the Display switch, the display toggles between 
the spectrum and waterfall modes. Functions such as Display and Marker A / 
Marker B execute immediately. The other right-hand switch functions require 
input. I opted to use a keyboard with the mouse for input. 

Any of this of interest? How would you use a mouse (other than to QSY the 
rig's VFO frequency)?

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[donovanf]

Hi Fred, 


You can easily replicate the unwanted PTT delay as follows: 


- Set the K3 to CW mode, 
- Turn VOX on . 
- Set the VOX delay to a fairly large delay so its to observe. 
- Key the PTT line 
- You will observe the unwanted VOX delay after you unkey the PTT line 


You can easily replicate the unwanted K3 internal keyer behavior as follows: 


- Set the K3 to CW mode 
- Turn VOX off 
- Plug a paddle into the K3 
- Operate the paddle. 
- The K3 will switch from transmit to receive and the external amplifier 
key output will deactivate after each Morse element, just like it does in QSK 
mode

This is getting harder to understand than organic chemistry was. See 
interspersed questions and results of trying to duplicate. Somehow, 
keying an external amp has come into this, the issue I've been trying to 
duplicate for you was excessive delay in going back to receive.

With VOX and QSK off, I can step on the footswitch [or plug the Winkey 
PTT output into the K3 PTT jack] and transmit. When done, either 
reverts to RX essentially instantly. The Winkey may hang just a tiny 
bit, very hard to tell. I will fire up the WK3 Tools program and see if 
there's a delay programmed in.

Yes, I operate a lot of CW contests and events, both manually with 
pencil/paper logging [just to add some interest to what otherwise 
becomes mechanical], and with N1MM+ [when I care about a score]. I'm 
somewhat familiar with the protocol.

I can't make this happen on my K3. VOX off/QSK off, the K3 reverts to 
receive as soon as I release PTT. I use the footswitch on SSB and I've 
used the CW+SSB option occasionally. Works exactly as advertised.

Hmmm ... "unacceptable behavior for contest operation?" There are 
several thousand K3's out there, many in contests, and a number of 
DXpeditions have used them. That's a fairly broad assertion considering 
how common they are and how long the K3 has been around.

When keying the K3 using RTS/DTR from N1MM+, Windows will very 
occasionally lapse into 90 WPM Klingon, almost always at exactly the 
worst time, of course. That's why I went to the WinkeyUSB. I'm 
left-handed but I normally send right. However I have a second paddle on 
the internal K3 keyer on the left and I switch often in a contest 
depending on which hand is free. They seem to work exactly the same for me. 

I thought I might be able to help but that does not seem to be the case 
here. I'll defer to others who understand what's going on better than I do.

Re: [Elecraft] winkeyer

[donovanf]

Hi Jim, 



I've never had a problem with external computer keying through the 
K3 serial port, it works fine in K3 CW PTT mode. 


My recommendation is to: 
- remove the unwanted VOX delay applied to the end of the PTT 
in VOX mode 


- Eliminate the unwanted QSK behavior of the internal keyer when 
the K3 is in CW PTT mode. Ideally the improved K3 behavior 
should be just the very well designed K1EL WinKeyer that so 
many of us are using because the K3 internal keyer is so bad.

I don't think the suggestion is to emulate a WinKeyer to contesting

WinKeyer when you send with a paddle and for the amp keying line to 
behave like the WinKeyer when sending either with the paddle, or from 
the computer via the straight key jack or the DTR line. 

Right, Frank?

[Elecraft] Fwd: Mayday K3 no receive no output

[W0MU Mike Fatchett]

I need some help.  I am down in V31 for the ARRL DX CW contest. Took the
K3 out of the carry on and the receiver is dead.  No signals received on
A/B or rcv in.  The radio did take a fairly hard hit when it was knocked
over in the case at the airport.

I have essentially take the radio apart and reseated everything but the
front panel.

I reloaded all the firm ware.

The radio has the ATU unit, dual receiver Transverter board, new syn board.

TX cal tests failed with 0 watts.

I deoxit the pins etc.

Any ideas or direction?

Both receivers are dead.

I think that lot of us who travell are interesting in that experience and think

I spent last three month travell from Europe to Canada and USA with KX3 and

Kevin,

I would suggest that you get an electrician to check the wiring to that 
outlet and the end in the breaker box.  That sounds like too much AC 
line drop to me.


You may have to do that check on all outlets on that AC circuit.  If 
they are wired with "Backstab" connections, those connections should be 
changed to move the wires under the screwheads.
Failure to do so can result in overheating a poor AC junction, and in 
the worst case a fire.


I would attend to that matter before changing the transformer tap.

If you are calling in an electrician, you might be better off to have 
him run a dedicated 240 volt line to the shack, but while that would 
solve the problem for the KPA500, my feeling is that you still would 
have a potentially hazardous situation in the AC circuit you are 
currently using.

Re: [Elecraft] KX2 v KX3 for air travel and hotel operation

Nice write up. Enjoyed knowing your experiences and totally agree about the 
differences between the two radios.  My K3s is another atomosphere  above the 
KX3.   

About the key, it is mounted in a durable plastic, I would guess  to keep it 
light, if any of it were to experience undue stress , I would think it could 
cause what you are experiencing.  I have the same key and have yet to take 
portable, waiting for moderate weather.  Mine works just fine for now.  Since I 
prefer SSB I have no intention to us anything other than my N3ZN which I 
actually prefer to use more than the two Bengali's I used to own.  It is small, 
not all that light, but the adjustments match all I could do on the B.

Subject: [Elecraft] KX2 v KX3 for air travel and hotel operation

Dear OMs and YLs,

 

   This is just to relate my experience and observations after using my

KX2 sn 1000 in Tenerife for the past week.This operation was just a side

event while travelling with my XYL - just a bit of fun.Previously a KX3

was used for such operations but for me the KX2 has advantages:

 

1) KX2 is smaller and lighter.

 

2) The battery charge is much faster taking about an hour maybe two rather than 
up to sixteen hours.

 

3) The battery can be kept outside the KX2.   I have a spare Li-Ion battery

from Elecraft.   One battery was in the radio in case airport security

wanted me to turn it on - they did not. A second spare battery was tucked 
neatly into the

KX2's larger carry case.   Airport security did not question the second

battery.  

 

4) Some people have complained about vulnerable speaker wires when opening the 
KX2 but for me the KX2 is less vulnerable to damage than the KX3

ribbon cable.  Taking the batteries in and out is easier with the

KX2 than the KX3.

 

 For twenty QSOs the battery was only recharged once this took one hour.
The power level was 5 Watts with the display light turned off.   The antenna
was an AlexLoop which I prefer to almost anything else for holiday style
portable operations when flying.It is a very unobtrusive antenna which
works far better than I ever expect.The Alexloop is light and packs into
a small case provided by the manufacturer.AlexLoop assembly is quick and
easy.   The AlexLoop was mounted on a broom handle and tied to the hotel
room balcony just placing the antenna above the wall by about a foot.One
imagines the wall to be reinforced concrete.   The QSOs were mostly around
Europe though one QSO was made with K1RM in Connecticut and the best DX was 
with WA8RCN in Ohio.

 

 I just about never bother with the QRP frequencies for such operations.
CQs are not made but stronger signals are answered.   Often I wait till a
QSO finishes before seeing if there is an opportunity.Sometimes the
signals are too weak for more that a rubber stamp QSO but other times a rag
chew developes.   I prefer the rag chew.

 

 I am not sure how things would work on SSB as CW is my mode and has great 
advantage over SSB when operating QRP into a one meter diameter antenna.

 

  The KX3 is a better radio than the KX2 and for me the KX3 receiver
with roofing filter does a better job.   One losses 160M and 6M with the
KX2.  Though TB is my band this is just not going to work out from a hotel
room balcony.   It would be nice if the KX2 had a dimple on the tuning knob
but this is a small point.The KX2 is not a radio for the base station
but the KX3 can serve this roll admirably.   The KX2 is a travel radio with
a great display which does all I need.

 

  Now for my gripe.   The KX2 paddle is nice and small.   I find it
handy to have the paddle attached to the KX2 when operating portable and
especially if on a park bench.When adjusted this paddle works just fine.
It is not a Begali but the AlexLoop is not a Yagi.   The trouble is that my
KX2 paddle kept going out of adjustment sometimes with a short between two 
contacts and at other times with one of the two center posts coming loose.
I am not a paddle slapper and normally operate with a close spacing and
light touch.The KX2 paddle caused me repeated problems.   I have written
the mother ship about this and will see if my paddle can be serviced.
Earlier this month, I did note someone else having similar problems.
Perhaps the Begali Adventurer paddle with KX2/KX3 mounting bracket is a
better if more expensive option.   It is also at least twice as large but
would fit easily in the KX2 carry case.  I am just not sure if my Begali 
bracket has the same problem that the original KX3 paddle bracket had with the 
KX2.

 

  So this is my story.   The KX2 is a lot of fun for CW QRP operations.
My KX3 will be kept but will not travel so much.   If you are flying and
need an unobtrusive antenna 

[Elecraft] KX2 paddle problem addressed

[Doug Turnbull]

Friends,
Elecraft got back to me and are going to take care of my paddle.   They
have made improvements.   For one thing a blue locktite which can be undone
is now being used for the center posts.   They have also improved the way
the finger pieces mate with the gap screws.

 So I am happy about these new developments.

Subject: [Elecraft] KX2 v KX3 for air travel and hotel operation

Dear OMs and YLs,

 

   This is just to relate my experience and observations after using my

KX2 sn 1000 in Tenerife for the past week.This operation was just a side

event while travelling with my XYL - just a bit of fun.Previously a KX3

was used for such operations but for me the KX2 has advantages:

 

1) KX2 is smaller and lighter.

 

2) The battery charge is much faster taking about an hour maybe two rather
than up to sixteen hours.

 

3) The battery can be kept outside the KX2.   I have a spare Li-Ion battery

from Elecraft.   One battery was in the radio in case airport security

wanted me to turn it on - they did not. A second spare battery was tucked
neatly into the

KX2's larger carry case.   Airport security did not question the second

battery.  

 

4) Some people have complained about vulnerable speaker wires when opening
the KX2 but for me the KX2 is less vulnerable to damage than the KX3

ribbon cable.  Taking the batteries in and out is easier with the

KX2 than the KX3.

 

 For twenty QSOs the battery was only recharged once this took one hour.
The power level was 5 Watts with the display light turned off.   The antenna
was an AlexLoop which I prefer to almost anything else for holiday style
portable operations when flying.It is a very unobtrusive antenna which
works far better than I ever expect.The Alexloop is light and packs into
a small case provided by the manufacturer.AlexLoop assembly is quick and
easy.   The AlexLoop was mounted on a broom handle and tied to the hotel
room balcony just placing the antenna above the wall by about a foot.One
imagines the wall to be reinforced concrete.   The QSOs were mostly around
Europe though one QSO was made with K1RM in Connecticut and the best DX was
with WA8RCN in Ohio.

 

 I just about never bother with the QRP frequencies for such operations.
CQs are not made but stronger signals are answered.   Often I wait till a
QSO finishes before seeing if there is an opportunity.Sometimes the
signals are too weak for more that a rubber stamp QSO but other times a rag
chew developes.   I prefer the rag chew.

 

 I am not sure how things would work on SSB as CW is my mode and has
great advantage over SSB when operating QRP into a one meter diameter
antenna.

 

  The KX3 is a better radio than the KX2 and for me the KX3 receiver
with roofing filter does a better job.   One losses 160M and 6M with the
KX2.  Though TB is my band this is just not going to work out from a hotel
room balcony.   It would be nice if the KX2 had a dimple on the tuning knob
but this is a small point.The KX2 is not a radio for the base station
but the KX3 can serve this roll admirably.   The KX2 is a travel radio with
a great display which does all I need.

 

  Now for my gripe.   The KX2 paddle is nice and small.   I find it
handy to have the paddle attached to the KX2 when operating portable and
especially if on a park bench.When adjusted this paddle works just fine.
It is not a Begali but the AlexLoop is not a Yagi.   The trouble is that my
KX2 paddle kept going out of adjustment sometimes with a short between two
contacts and at other times with one of the two center posts coming loose.
I am not a paddle slapper and normally operate with a close spacing and
light touch.The KX2 paddle caused me repeated problems.   I have written
the mother ship about this and will see if my paddle can be serviced.
Earlier this month, I did note someone else having similar problems.
Perhaps the Begali Adventurer paddle with KX2/KX3 mounting bracket is a
better if more expensive option.   It is also at least twice as large but
would fit easily in the KX2 carry case.  I am just not sure if my Begali
bracket has the same problem that the original KX3 paddle bracket had with
the KX2.

 

  So this is my story.   The KX2 is a lot of fun for CW QRP operations.
My KX3 will be kept but will not travel so much.   If you are flying and
need an unobtrusive antenna consider the AlexLoop.   This antenna has done
some amazing things for me in contests with a KX3.

Re: [Elecraft] Considering KPA500/KAT500 Combo with Flex 6500

[Kevin - K4VD]

Hi Bill.

A Fluke plugged into the same outlet shows 120.0 VAC unkeyed and 116.9 VAC
(60 V internal) keyed with 190 watts out. 114.4 (55 V internal) with 500
watts out.

This is CW.

I could drop the tap down to RED (106-115 VAC). I kind of feel I'm on the
borderline. I'm trying to get a buddy to listen for my signal to see if
there's any anomalies he can identify. I'm getting a low hum at key down
but reading the book that seems about normal. Nothing bothersome.

Re: [Elecraft] Considering KPA500/KAT500 Combo with Flex 6500

[Bill Johnson]

Ken, From what I know, sounds like the line voltage may be low when keying 
down.  Measure it with the amp running if you can.  If it stays steady, you are 
ok.   I don't know your house wiring and fusing, check that.  #14 wire is good 
at 15 amps at the breaker and #12 is fused at 20 amps.  If the line voltage 
dips and nothing blows in the fuse box given these numbers, then might moving 
the tap.  The manual is clear on settings.  Depending on the line load and the 
house wiring size and fusing, then you might have to do a bit more.  My line 
voltage is closer to 125V and fused at 20, the amp stays above the 60 volts 
always and I run full power with SSB.  I left the default on my factory KPA500. 
 I think it comes set at the higher voltage.

I feel like a kid with his first BB gun. Real nervous every time I pull the 
trigger. But so far things seem to be working as they should.

I hooked the Flex 6500 through the KPA500 to the KAT500 after doing all the 
setup stuff. My supply voltage is 120.7 VAC and HV reads 73.7 until I key down. 
I used the yellow tap. It drops to 54 V which seems kind of low. The book says 
less than 60 volts with reduced output power and as low as 40.
Not sure if I should move the tap from yellow to red. I'll leave it on yellow 
for now.

A quick test of input vs. output shows around 14 A max:

inout
10190
15290
20380
25460
30520

That was on 40 meters. On 20 meters the output is a bit lower with 500 being 
reached at 35 in. I'm setting the rig's max out to 35 watts.

I'm not using DDUtils or the new USB band data stuff from Flex quite yet. I 
just have the basic setup of keying and letting the auto-band detect do its 
job. So far so good I think.

Still some testing and getting over the nerves left to do. The antenna is a 
dipole except hex on 20.

Did anyone else almost jump out of their chair the first time the KAT500 tuned 
up? I'm having a good day! :)

[Elecraft] KX2 on EA8 travels

[Doug Turnbull]

Dear OMs and YLs,

   This is just to relate my experience and observations after using my
KX2 sn 1000 in Tenerife for the past week.This operation was just a side
event while travelling with my XYL - just a bit of fun.Previously a KX3
was used for such operations but for me the KX2 has advantages:
1) KX2 is smaller and lighter.
2) The battery charge is much faster taking about an hour maybe two rather
than up to sixteen hours.
3) The battery can be kept outside the KX2.   I have a spare Li-Ion battery
from Elecraft.   One battery was in the radio in case airport security
wanted me to turn it on - they did not plus the spare tucked neatly into the
KX2's larger carry case.   Airport security did not question the second
battery.  Some people have complained about vulnerable speaker wires when
opening the KX2 but for me the KX2 is less vulnerable to damage than the KX3
ribbon cable.   Taking the batteries in and out is also much easier with the
KX2.

Re: [Elecraft] P3 product suggestion

[n9tf]

I also would agree with this suggestion for a mouse function to the P3 for ease 
of QSY. The marker/dial and tap (push) button function on the P3 is OK for 
casual QSYing. But in a contest situation, especially CW, pointing and clicking 
on a signal would be much faster and I would think far more accurate. I know I 
would use this a lot. 
I thought I read another post earlier that from a firmware standpoint it would 
require some additional lines of firmware. If that's the case, sounds like a 
relatively quick enhancement?

I fully agree, a mouse click qsy would be wonderful, been waiting for this 
for over a year now..  Jim K4JAF

I too would like to see a mouse click QSY, for reasons others have mentioned 
plus one.  It would be far faster, and it could be more accurate.  The knob 
on mine is cruder than the K3's own encoder, requiring a bit of fiddling to 
get it right on.  In addition, when I press the knob sometimes the whole P3 
moves backwards.  I suppose I could strap a brick on top, but a wireless 
mouse would look better.

Hi,

I am using the Winkeyer USB since I bought my K3S last year. Really enjoy it 
and well supported my all major softwares.

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[Fred Jensen]

This is getting harder to understand than organic chemistry was.   See 
interspersed questions and results of trying to duplicate. Somehow, 
keying an external amp has come into this, the issue I've been trying to 
duplicate for you was excessive delay in going back to receive.


On 2/14/2017 10:22 PM, donov...@starpower.net wrote:

Hi Fred,

CW PTT is the K3 CW operating mode when VOX is off and
QSK is disabled.
With VOX and QSK off, I can step on the footswitch [or plug the Winkey 
PTT output into the K3 PTT jack] and transmit.  When done, either 
reverts to RX essentially instantly.  The Winkey may hang just a tiny 
bit, very hard to tell.  I will fire up the WK3 Tools program and see if 
there's a delay programmed in.


Two distinct categories of messages are sent during CW contests:

-- prerecorded messages (CQ, exchange and end of QSO messages)
They're usually stored in an external computer so that they can
be instantly started and prematurely stopped by the contest
logging program if necessary.

-- real time operator originated messages, keyboard or paddle sent
Yes, I operate a lot of CW contests and events, both manually with 
pencil/paper logging [just to add some interest to what otherwise 
becomes mechanical], and with N1MM+ [when I care about a score].  I'm 
somewhat familiar with the protocol.


If CW PTT is selected by the operator, unfortunately the K3
actually sends the message in QSK mode. If the operator selects
CW VOX mode, a very short VOX delay will result in VOX
dropouts between every character and word. If the operator
increases the VOX delay to at least 250 milliseconds to avoid
inter-character and inter-word dropouts, the 100 millisecond
transmit-receive switchover for real time messages cannot be
achieved because unfortunately the K3 adds a VOX delay to
the end of the computer generated PTT when the K3 is in VOX
mode.
I can't make this happen on my K3.  VOX off/QSK off, the K3 reverts to 
receive as soon as I release PTT. I use the footswitch on SSB and I've 
used the CW+SSB option occasionally.  Works exactly as advertised.


A very effective solution is to use an external K1EL Winkeyer
and not use the internal K3 keyer because of  its unacceptable
behavior for contest operation.
Hmmm ... "unacceptable behavior for contest operation?"  There are 
several thousand K3's out there, many in contests, and a number of 
DXpeditions have used them.  That's a fairly broad assertion considering 
how common they are and how long the K3 has been around.


Perhaps the most desirable solution is to correct the shortcomings
of the current K3 internal keyer and eliminate the unwanted
VOX PTT delay so that K3 behavior is similar to the Winkeyer.
When keying the K3 using RTS/DTR from N1MM+, Windows will very 
occasionally lapse into 90 WPM Klingon, almost always at exactly the 
worst time, of course.  That's why I went to the WinkeyUSB.  I'm 
left-handed but I normally send right. However I have a second paddle on 
the internal K3 keyer on the left and I switch often in a contest 
depending on which hand is free.  They seem to work exactly the same for me.


I thought I might be able to help but that does not seem to be the case 
here.  I'll defer to others who understand what's going on better than I do.

Re: [Elecraft] winkeyer

[Jim Brown]

I don't think the suggestion is to emulate a WinKeyer to contesting 
software, but rather for the internal keyer to have the same logic as 
WinKeyer when you send with a paddle and for the amp keying line to 
behave like the WinKeyer when sending either with the paddle, or from 
the computer via the straight key jack or the DTR line.


Right, Frank?

[Elecraft] Looking for un-loved HEX beam or similar

[Niel Skousen]

Good Morning Gang,

I'm looking for a used or out of service hex beam or similar light weight 
20m~10m hex beam or similar.

I have a mast up, and a rotor, and have been looking at building a W8JK beam, 
but thought I'd just ask if there was anything out there that needed a new home 
before starting another project.

Thanks & 73
Niel

Re: [Elecraft] Feature Request: improved internal keyer and CW PTT behavior

[donovanf]

Hi Richard, 


The K3 and external K1EL Winkeyer is a great combination, it corrects 
most of the deficiencies of the internal K3 keyer and PTT VOX delay. 


Hopefully the next next upgrade of the K3 internal keyer will at least 
make it better, if not perfect! The biggest faults are: 
- VOX delay added to the tail of the PTT signal when in VOX mode 
- inability to use the internal keyer in CW PTT mode, it always reverts to QSK 


Thanks for your wise observations!

behavior 


Frank, 


In a nutshell, what you would like is PTT control when the CW comes from the 
computer (via the straight key jack), and VOX when the paddles are used (via 
the paddle jack). 


OK - but it may not be quite as simple as it seems. Not that it cannot be done, 
but it might not be quite so easy to program and debug. 


First off, some users might want VOX from both inputs (in particular, someone 
using QSK probably would). So, this looks like a new configuration option - VOX 
from the paddle input only, but not from the straight key input, vs. the 
standard option with VOX enabled on both inputs. OK so far. 


Suppose you are using the paddle and want to continue directly with a computer 
message. If you hit the function key before the VOX has dropped, the computer 
will assert PTT and the rig will stay in the transmit state, but you will want 
the VOX delay to be disabled for the duration of the computer message, i.e. the 
firmware has to remember not to impose the VOX delay, whereas it would have 
done so if you had not hit the function key. The state machine is getting a bit 
more complicated. 



Now, what happens if the operator wants to interrupt a computer message by 
touching the paddle? Using a Winkey, touching the paddle aborts the 
computer-generated CW. If you want to be able to do this, then touching the 
paddle will have to turn the VOX delay on and temporarily disable the straight 
key CW input. Meanwhile, the computer has no way of knowing what has happened, 
so it has not dropped PTT. If the paddle input plus VOX delay ends before the 
original PC message is finished, the computer will still be asserting PTT and 
toggling the CW line. You will want the rig to continue to ignore the straight 
key input until the computer releases PTT - but in the meanwhile, do you also 
want the rig to be ignoring the hardware PTT from the computer and switching 
back to receive, even while the computer is still "transmitting"? This could 
get messy. Maybe the easier choice would be not to allow paddle input to 
interrupt the computer keying, so you have to hit the Esc key before usin
 g the paddle. Simpler to implement, but not nearly as convenient as using a 
Winkey. 


Add to this the fact that the interaction between CW and PTT in the K3 has 
always been somewhat problematic (witness the CW problems when the TX Delay 
setting is changed from the default 8 ms); throw in the fact that somehow this 
has to work even when computer PTT is done via software commands rather than a 
hardware signal (this has historically been a significant problem area for the 
K3 that was addressed in F/W revision 5.46 after significant testing effort); 
and maybe programming and debugging this might just turn out to be harder than 
it looks. 


Maybe the easiest solution is just to use a Winkey after all! 


73, 
Rich VE3KI

Re: [Elecraft] Tracking Elecraft Feature Requests

[Bob N3MNT]

In a competitive business environment  especially where you are viewed as an
innovator, having a public prioritized list of potential new features could
negatively impact a company.  I think Elecraft has done a much better job of
responding to customers requests than most all Amateur radio suppliers.

Re: [Elecraft] P3 Product suggestion

Yeah after hitting send on the original post, I had the same thought about
HDMI instead of SVGA. Absolutely.
I also thought about the touch screen idea, but that's readily handled by a
touch screen with mouse emulation.
I think my biggest problem with the concept that I haven't completely
thought through is the fact that now I'd have TWO mice next to my keyboard,
in addition to the paddles and maybe someday a kpod. It's getting crowded
and with two mice, my chances of grabbing the wrong one would be
approaching 90%...
I'm willing to live with it :)

[Elecraft] Wow! Early Morning QRPing on 80 Meters

[Pete Meier]

Hi all,

While Ed AB8DF is on vacation I am stepping in until his return at the end of 
the week to keep this great thing going and growing.

Today was an Great day even though conditions were noisy with QRN. I worked 4 
stations from my qth in Manitou Springs, CO and only called CQ once. What fun!
Today I used a newly acquired mcHF SDR QRP Transceiver Kit by M0NKA built by 
Steli, AE6OR. I ran 5 watts into an end fed half wave up about 30 feet.
Check out the mcHF at http://www.m0nka.co.uk 

I worked:
W3KCCHARLES in DAMASCUS, MD
K5PDPETE in SUNNYVALE (DALLAS), TX
W4MJE   JIM in MOBILE, AL
KD9VT   DAVE in SILVIS, IL

I appreciate the skills and patience of all the station operators who contact 
me. It makes getting up so early here worthwhile. 

Like Ed I will be hanging out on 3.560 most weekday mornings from 1200z to 
1300z 
while I have my morning coffee. Just might be the way to survive the sun 
spot lull.

Pete WK8S

Re: [Elecraft] Tracking Elecraft Feature Requests

[Bo3b]

Asked Elecraft Support, and Wayne directly, some weeks ago about a company
maintained "public" Product Feature Request list - No specific reply so I
assume company not interested in making information on suggestions they
receive available. Any feedback collected via this forum might be helpful
but a Customer/Company reconciled and consolidated list would most likely be
best.

Also mentioned that a similar database for known firmware defects would be
useful. I reported at least 3 possible issues related to the KX2 and know
from professional experience that to accurately document and report
suspected issues can take significant time - An ongoing, up-to-date list of
Elecraft acknowledged problems would help Users avoid wasting time
investigating perceived problems. And make Customers more prone to report
potential issues - Everybody wins. And BTW, this includes documentation.

Additionally, a firmware upgrade/fix release schedule for known defects
might also prove useful.

Bob

Re: [Elecraft] [OT] end-fed halfwave antennas

[Gil via Elecraft]

Hello,

I wouldn't bother with a J-Pole type antenna for HF. The only one I made
remotely close was a Slim Jim for 6m, with ladder line. It worked well.
Making an UNUN for an end-fed is much simpler. All it takes is one
toroid and one capacitor if you want it to be adjustable.

My favorite portable antenna now is a 9:1 EARCHI UNUN, a 19ft wire and a
6m fishing pole. It's not a half wave but it works well down to 40m. If
I can find a tree then I throw a half wave wire and tune it with my
Ilertenna end-fed tuner. There is only one "tie-up" point, very
practical and gives me a low radiation take-off angle.

Except for 80m I'm done with horizontal antennas, especially in the
field. It's just too hard to get them high enough and the results are
never as good as an EFHW.

The only instance I would use a counterpoise wire with an EFHW is if my
coax cable (RG-174) is shorter than 25ft. Otherwise it doesn't make any
difference that I can tell.
