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

[donovanf]

Okay, lets take Eric's lead and open an interesting thread directly 
related to an excellent Elecraft product. 



For years many of us have suffered with the odd behavior of the K3 
in CW PTT mode. There are at least two inexplicble aspects of K3 
CW PTT behavior that have forced many of us to use external 
Winkeyers rather than the poorly designed internal K3 keyer logic 
when the K3 is in CW PTT mode. 


For CW contesters, its necessary to operate the K3 in PTT mode 
to avoid unwanted VOX delay. But for some strange reason the 
K3 always applies VOX delay after external PTT is unasserted. 
I can think of no logical reason why VOX delay should be applied 
at the end of the external PTT input when the K3 is PTT mode or 
any other mode. When PTT is unasserted, the K3 should always 
immediately return to receive mode, no exceptions. 


When using the internal K3 keyer when in PTT mode, for some 
inexplicable reason the K3 behaves like its in QSK mode. The 
only way to avoid this is to use VOX rather than PTT mode or 
to use a foot switch when in PTT mode. Both alternatives 
are unacceptable. 


The band aid solution many contesters use with excellent results 
is to avoid using the internal K3 keyer and to use an external 
K1EL Winkeyer that generates both a key output and a PTT 
signal generated according to well designed Winkeyer CW PTT 
logic. 


Why can't the K3 implement logic similar to the Winkeyer to 
generate the equivalent of "Winkeyer PTT" when using the K3 
internal keyer when the K3 is in PTT mode?

Re: [Elecraft] K2 IF output

[Bob]

Hi Ron,

The filter was a 200kc wide bandpass filter so you would see all 
the signals of interest.  So may have helped with the input to the LP Pan which 
was the hot setup back then.

If you want to see spectrum on either side of the signal, you do not want a 
filter in the loop. Ideally, you would see the entire spectrum *before* any 
I.F. filtering on the panadapter.

The Cliffton Webb unit was specifically made for K2 exact signal/clean easy 
physical fit internally, and a external  IF pass band filter for a clean 
signal no matter what kind of signals are present in your shack.

Not a area of your receiver where you want to be hacking about. Just saying.

I stumbled across a K2 for sale on Ebay that I thought was rather 
"interesting".  It's one of those situations where you have no idea what you 
are really getting!

The K2 is actually described as a "CB radio"!  Wow!  Makes you wonder. 
Also, it is later described as a "K2/100", but that has to be wrong since it 
has no heat sink!  At least they do say "As IS for parts/repair".

Now, there probably is some value here, and maybe some good value, but how 
can you possibly tell?  Right now the bidding is up to $280, with a couple 
of days to go.  I'm just curious how much this thing will sell for.  If 
anyone else is curious, it is item # 162388838126.

The Clifton Labs Z1B was a general purpose instrumentation

The buffer amp at QRP projects is specifically designed for the K2.

Re: [Elecraft] KX3/PX3/KXPA100 - PX3 taking 5 minutes to come on??? KXPA100 loses mind...

[n6hz]

Hi David, 

I'd prefer to have folks that are experiencing this problem email me
directly.  That way I can determine the best resolution path. The fix
involves replacing a surface mount capacitor which is located under the
power supply board on the front panel board. 

Kindly, 

Paul

Re: [Elecraft] KPA500 fan noise

[David Orman]

Noiseblocker does too (92x92x25), which I prefer due to color. :) I have no
idea if this is the correct size for the KPA500, I don't have one, and
can't vouch for doing the mod. BlackSilentPro would be the model I've used
in past fan replacements on switches and such. Disclaimer, I have no idea
how this will influence the thermal control of your KPA500. YMMY/mod at
your own risk. Perhaps a call to Elecraft to discuss?

[Elecraft] (OT) Follow-up on CW Resonant Speaker

[stan levandowski]

Folks, I posted about having built the CW Resonant Speaker in the 
February 2017 and having problems with low audio.  This is a follow-up 
report for those with interest in this subject.


It works!  It's fabulous!  It's unbelievable how great it sounds! CW 
pops out and background noise is significantly reduced.



I built it EXACTLY as described in the article and ordered the EXACT 
parts listed.  My problem was not enough audio coming from either my KX1 
or my KX2 headphone jacks.  



I purchased a fully assembled 15 watt mono amplifier - Qianson TDA2030A 
15W Mono Channel Audio Power Amplifier Board AC/DC 12V AMP Module - 
Amazon for $11.80.



With the new amp, my speaker is acoustically resonant at 760 Hz and I 
have plenty of volume; enough to fill the room.  The author had claimed 
"around 700 Hz" so it's in the ballpark.  I can verify that the 
construction article was accurate.



I wanted 600 Hz so I built a vinyl sleeve to insert into the street 
elbow and set my sidetone pitch for 600 Hz then slid the sleeve up and 
down until I got a very obvious peak in volume.



I'm still a "can fan" for serious CW operating, but it's nice to be able 
to listen to sweet CW that pops right out now that the higher frequency 
sounds are substantially subdued.



This was a really worthwhile little project.


73, Stan WB2LQF

Re: [Elecraft] P3 "Point and Click"

[Tim Tucker]

What is this "mouse" think you speak of?  I've moved on to using NAP3 or
HRD with the touch screen :)  It works really well on DigitalMaster with
the digital modes:  Touch the waterfall, start typing.

Actually, that's not entirely true...there are  just some navigation
elements that do work better with a mouse.  But not having point and click
with mouse is one of the reasons why I never did the P3, either.

[Elecraft] EFHW

[Dauer, Edward]

Same sort of experience here.  In 1957 if my DX-20 could load it, I transmitted 
with it.  I didn’t know any better. I should say, however, that when I lived in 
R.I. during the peak years of Cycle 19 and in New Haven during the peak years 
of Cycle 21, having the ocean as a neighbor didn’t hurt either.  Certainly 
better than the thick layer of decomposed granite my shack sits on now.

Hi Fred, 


When I started DXing in about 1962, Solar Cycle 19 was quite weak 
and reached its minimum in 1964, the year I made the #1 USA low 
power score in the ARRL CW DX Contest using my 20 meter Happy 
Accident Ground Plane and a variety of other wire antennas suspended 
from that same maple tree in an urban area in the city of Providence, RI

[Elecraft] Fwd: Re: k-pod data cable

[Wes Stewart]

Further to this.  At the time I wrote the previous message my K3S/100F was back 
at the factory again. On a previous visit Elecraft had installed the resistor 
need to power the K-Pod through the RJ12 connection.  So I was using my old K3 
without the mod and powering the K-Pod from an external power supply.  Couple 
that with the extension cable and I was reluctant to insist that the K-pod was 
really the culprit in the "dropped message" problem.


But since the radio has returned, I've used the K-Pod with the factory-supplied 
cable and I still get instances of a button tap activating a message, as 
displayed on the radio, but no message is actually sent.  BTW, this is with the 
TX disabled, so I don't want to hear the all too frequent, "You have RF in the 
shack and need a common-mode choke" answer.


Unfortunately, I have to keep this paperweight connected to the radio since when 
my fiancee asked what I wanted for Christmas, I said, "a K-Pod" and she bought 
it for me.


If Elecraft wants me to change my opinion on this they will make it possible to 
store the macros IN THE K-POD and play them out instead of the convoluted way 
it's done now.  IMHO of course.

1) Let's get it straight that the connector is RJ12, not RJ45. I've already
posted on using an adapter to extend the Elecraft-supplied cable from the radio
to the K-Pod.

2) I have Macro 13 (tap F5) set to activate MSG 1 (SWT 21)  As I've written
before, many times, tapping this button resulted in "MSG1" displayed on the
radio but no message was transmitted.

Jeff makes an excellent point about long data cables. If you decide to try a
longer ribbon cable first and are not interested in making your own, buy an
RJ45 cable and F-F coupler to extend the Elecraft cable. Be sure to put the
Elecraft cable closest to the K3, since it does not have pin 1 connected,
and use the RJ45 cable for the rest of the run.

Let me repeat my earlier comment: Macros 1 through 8 are accessed by HOLDING
the KPOD switches for more than 1/2 second. Tapping (holding for less than
1/2 second) accesses K3 Macros 9 though 16. That might be what some of the
people experiencing "unreliable" switch behavior are doing and not getting
the reaction they expect from macros 1 through 8.

Re: [Elecraft] EFHW

[Morgan Bailey]

I will also testify that this antenna has worked well for us. My son above,
NS0R, has used it in favor of a beam because of a tower HOA issue with his
wife. LOL. Both of us have literally worked thousands of QSO with this
antenna. The Parallel tuner will handle most any HIGH impedance antenna,
that being 2000-5000 ohms. Having a roller inductor in parallel with a
variable cap really makes the difference. Once the dip is attained, the
bandwidth is the whole band on 20, and 15 both phone and CW will be under
2:1 or better. The hard part is getting the stray capacitance in the
construction out of the box. At times that has been problematic, but still
workable.

Re: [Elecraft] Full kits,

[Harry Yingst via Elecraft]

I've found that surface mount is not that hard just different.
Probably the same as when electronics switched from Tubes with point to point 
and big irons to PC boards with IC's and and smaller irons.
In a lot of ways surface mount is easier, (no leads to bend, reshape and trim)

I do have to agree It does seem that other hobbies are taking the lead in going 
to surface mount.

tl:dr I like to build things. Getting all the components

I have built several kits with SMD components using just a

with a cheap Radio Shack soldering iron, but I certainly don't

The basic approach is to tin the pads on the board with solder 
and clean things up so there are no bridges. Solder one 
end/corner of the device and adjust it so it lines up with all 
pads. Then go and solder the rest of the pads. This technique 
works well with 8 pin devices. I would be in unknown territory

This assumes the keyboard and mouse have separate / dedicated 2.4 GHz
wireless dongles.  There are plenty of keyboard / mouse combos which share
the same wireless dongle.  I've tested several of them with my PX3.  Of
course, the PX3 ignores the mouse HID report at the moment, however, the
keyboard HID report is interpreted just fine.

USB hub support is certainly preferred, allowing users more flexibility in
selecting their keyboard and mouse.  As we've noted in the past, USB hub
support would allow a thumb drive to be connected with the keyboard and
mouse.  For example, a unique key combination could be used to capture the
P3 / PX3 screen to the thumb drive.  The P3 / PX3 currently supports the
ability to capture the screen, however, you first must remove the keyboard
dongle and insert the thumb drive.

I suspect many (most?) users would be content with only Mouse-n-Click QSY
(no keyboard).  This wouldn't require USB hub support.

Re: [Elecraft] P3 "Point and Click"

[Ian White]

Sorry, Frank, but the claim that the K3 VFO is faster than the mouse can
only be true for small frequency changes. 

The last time I asked Elecraft about this feature, I put this to the
test by comparing the two VFO knobs on the K3 against the small knob on
the P3-SVGA, and comparing both of those against an SDR panadapter that
was linked to the K3 and tuned with a mouse. 

The time taken to tune with a knob increases with the frequency span of
the display, and with a wide display this can take several seconds of
vigorous spinning. Changing into 'high gear' using the RATE button
doesn't really help because the button-presses bring a time penalty of
their own, plus a significant risk of stabbing the wrong button.

The unweighted VFO B knob is also significantly slower than VFO A.

But if the mouse is close to hand, the time taken to point and click
anywhere on the panadapter screen is *completely independent* of the
on-screen frequency span and is never greater than 2-3 seconds. My mouse
sits right between the keyer paddles and the K3 tuning knob so it's
always easy to find, and then the hand goes naturally back to the VFO
knob for the final zeroing-in. 

Meanwhile, the cursor knob on the P3 came in a hopeless third. For
anyone who needs to QSY quickly, this is not a serious operating
feature.

So there really is no contest here. For QSYing rapidly across a wide
frequency range to jump on new stations, the mouse is a very clear
winner.

And that, I regret to say, is why my second K3 purchase did not include
another P3. Without the mouse feature I wouldn't even consider it.

Re: [Elecraft] Full kits,

[Bill Frantz]

tl:dr I like to build things. Getting all the components 
assembled in a kit is a wonderful step forward toward the fun part.



I have built several kits with SMD components using just a 
temperature controlled soldering station. I think I could get by 
with a cheap Radio Shack soldering iron, but I certainly don't 
want to. (I like automatic spark advance in my car as well.)


The basic approach is to tin the pads on the board with solder 
and clean things up so there are no bridges. Solder one

Re: [Elecraft] P3 "Point and Click"

[Bill Frantz]

I normally tune using the P3/SVGA monitor for tuning. For me, it 
is a visual experience. During the WPX RTTY contest last 
weekend, I set my span to about 25, so I could see both tracks 
of the RTTY signal. I could get close enough to decode using the 
KPOD knob. I fine tuned by ear, and by using the Crossed Ellipse 
Indicator/XY scope in cocoaModem. I use a similar technique to 
tune CW and can get the APF tuned by lining up the tuning 
indicator with the signal in the waterfall.


The bigest issue with this technique is the lag between turning 
the knob and seeing the SVGA display change. Using a mouse would 
make the lag less important. Where I would a mouse almost all 
the time is in the big jumps. On a single band contest, I start 
at one end of the active area of the band and S my way to the 
other end. By then, the band conditions have changed enough that 
is is worth going through again, so there is a big jump to the 
other side of the active area. There are also sometimes gaps big 
enough to be too slow with knob turning.


There may be a technical implementation problem for Elecraft. 
The last time I paid attention, the P3 didn't support USB hubs. 
They would need hub support to use both a mouse and keyboard at 
the same time.

Re: [Elecraft] K3 with switching power supply??

[Jim Brown]

The K3/K3S draws peak current on transmit, and is generally greatest on 
the higher bands (especially 6M) where efficiency of the output stage is 
lower. The KAT500 draws max current when tuning. The rest of the time it 
draws very little current. In general, any PSU that will run the radio 
will also run low power accessories like the P3 and KAT500.

Re: [Elecraft] K3 with switching power supply??

[Mike Furrey]

Looking at the specs, the K3s could draw up to 25 amps max, the KAT500 could 
draw up to 1 amp max and the Powerwerx supply is rated at 25 amps continuous 
duty. So  It "may" be ok. That would depend on how long you hold the 
key down or transmit rtty. 

You can get the Powerwerx unit that contains the built in volt/amp meter or 
purchase the external meter unit and see what the actual current draw is on 
transmit.
I don't have a KAT500 so maybe someone else here has tried that combination 
with that power supply. I have had no issues with my K3 or FT857D or IC7200 and 
the LDG 200pro antenna tuner.

Re: [Elecraft] Question about N1MM+ Logger

[Cady, Fred]

N1MM is saying you have not entered the DX station's power into the QSO entry 
window.  So when trying test qsos, type the the dx station call, hit space, 
then enter a power and hit enter to send your report or log it, depending on 
whether you are S or running.

Also, after entering stuff into the log, if you type WIPELOG in the call sign 
entry field, N1MM+ will clean the log.  Although somehow we have had problems 
with that in a sequence number contest like SS where the sequence number 
doesn't get cleared and you start the contest with a number other than 001.  
Haven't sorted that one out yet.

This is arguably OT, but I have just installed the N1MM+ logger and haven't yet

for help . . .

Setting the program up for the ARRL DX Contest CW, when I try to enter made up

Manual says that when that message appears, it means there is some element in 
the exchange that is either missing or invalid.  When starting the new log file 
I entered "medium" for power, and entered as the exchange only "CO" for 
Colorado.  Actually, CO was already populated.  The ARRL rules provide that DX 
stations should include their TX power in the exchange, but that W/VE stations 
do not.  My U.S. QTH in the configuration file is correct.  So I am confused - 
anyone know why I am getting this error message?

Ameritron does not make a band switching cable for this combination.  Does
anyone have information for me to make or modify a cable?  The combination
works great but I sure miss the automatic amplifier band switching.  I have
the KX3 and the KXPA100 (using the KXPA100 utility command tester) both set
at 9600 baud because the ALS-1306 only accepts 9600 baud but I don’t
understand serial cables very well and the ALS-1306 does not use a standard
straight through cable or a null modem cable either.  It uses custom
proprietary cables for different radios.

Re: [Elecraft] K3 with switching power supply??

[Joe Subich, W4TV]

> I am on the way to change my old Astron RS35M power supply

Why would you change out an Astron RS35M?  Unless you need to
make the K3 station portable where the weight and size of the
Astron is an issue, the RS35M will be both much more quiet and
much more reliable than any switcher.

Even if the Astron is getting a little unreliable, an overhaul
(replacing the diodes, pass transistors and possibly filter cap)
is likely to be more cost effective than purchasing a switcher.

For repair/overhaul information see: 



or for a more in-depth modification/overhaul that replaces the 723
regulator see:

Re: [Elecraft] EFHW

[donovanf]

Hi Fred, 


When I started DXing in about 1962, Solar Cycle 19 was quite weak 
and reached its minimum in 1964, the year I made the #1 USA low 
power score in the ARRL CW DX Contest using my 20 meter Happy 
Accident Ground Plane and a variety of other wire antennas suspended 
from that same maple tree in an urban area in the city of Providence, RI 


http://www.sws.bom.gov.au/Images/Educational/The%20Sun%20and%20Solar%20Activity/Solar%20Cycle/Solar%20Cycle%2019.png
 


My antennas are a little better now...

Re: [Elecraft] K2 IF output

[David Anderson via Elecraft]

Ken,

Sorry to be the bearer of bad news, but G4HUP died last week at the age of 68, 
a great loss to the community.

We have no word on the future, if any, of his excellent products.

Re: [Elecraft] K3 with switching power supply??

[charlie carroll]

Well, here I am packing my bags for a trip to VP2M.  I think I will 
leave my RM35 home and take along the power werk switcher. I'll tolerate 
the few birdies I hear from the switcher for the difference in 
size/weight.  The answer to the question really depends on your situation.

Re: [Elecraft] EFHW

[Fred Jensen]

Well, the KFBK Franklin is two vertical 180 deg co-linear elements 
center fed [in-phase, I think], so I guess it would be about 1,600 ft 
[almost 500 m].  A couple of the TV towers in Walnut Grove down in the 
Delta are 2,000 ft [600 m], but they're not center fed. [:-)  I think 
most "half-wave" BC verticals are close to but not exactly 180 deg.  
IIRC, KFI [640 KHz] in Los Angeles has a 725 ft tower which is almost 
exactly 180 deg  but has a capacity hat that extends it to an effective 
195 deg or so. When you drive by it on I-5, it is one very tall tower.

ANY switching power supply is a potential noise source, and even the 
best can be heard in antennas that are close enough to it. The one 
Elecraft sells is pretty quiet, but I heard it in a 160M vertical that's 
25 ft from it.

Re: [Elecraft] P3 "Point and Click"

[Joe Stone (KF5WBO)]

Paul Saffren (N6HZ) can help us understand why we still haven't seen
Mouse-n-Click QSY support for the P3 and PX3.

If you use a 2.4 GHz wireless dongle which supports both a keyboard and a
mouse, the HID report sent to the P3 / PX3 contains not only the keyboard
information,

struct KBDINFO {
struct {
uint8_t bmLeftCtrl : 1;
uint8_t bmLeftShift : 1;
uint8_t bmLeftAlt : 1;
uint8_t bmLeftGUI : 1;
uint8_t bmRightCtrl : 1;
uint8_t bmRightShift : 1;
uint8_t bmRightAlt : 1;
uint8_t bmRightGUI : 1;
};
uint8_t bReserved;
uint8_t Keys[6];
};

but also the mouse information,

struct MOUSEINFO {
struct {
uint8_t bmLeftButton : 1;
uint8_t bmRightButton : 1;
uint8_t bmMiddleButton : 1;
uint8_t bmDummy : 5;
};
int8_t dX;
int8_t dY;
};

Obviously, the P3 / PX3 is ignoring the mouse information.

Basic Mouse-n-Click QSY functionality would require ~25 lines of firmware.

[Elecraft] deaf and dumb K3

[todd ruby]

Hi,
I was just operating on 15 cw working west Africa no problem, changed bands and 
all of a sudden no audio and no power out! RX ant is not engaged. Does anyone 
have any suggestions?

The radio has been fine last night and 20 minutes ago and again to restate, it 
has no audio and no power out even into a dummy load

Any help would be appreciated

thanks

todd

Re: [Elecraft] Hook up for K3, P3, KPA500, KAT500

[Mike Crownover]

Thanks Don. I finally figured that out. I also found a spare KPAK3AUX cable (I 
have no idea) in the shack. I'm up and running. 

73,

Mike AD5A 

Just a side note, I thought I ordered the KAT500-F, but I guess I ordered the 
kit. I brought the unopened box with me to a second QTH in Santa Fe, NM, where 
I was going to plug and play. Well I opened the box and realized that I had 
some work to do. I finished late and then tried to connect everything. My brain 
wasn't in high gear and reconciling the two diagrams just wasn't in the cards. 
After some coffee this morning and reviewing the drawings again, it made some 
sense. Then the fortuitous discovery of the needed cable, all is well.

Re: [Elecraft] EFHW

[Dan Presley]

I also wanted to thank Frank for a great suggestion.He hit it right on the 
nose. I always forget about the usefulness of an RF ammeter. When I was a kid 
in the ’60’s hanging around the OT’s a couple of them used these in the open 
wire lines to tune for maximum current. No concern of SWR as that wasn’t 
important with pi and linked outputs in your tube rigs! Now I just have to 
figure out a way to do this in the field…I still have some wonderful Weston 
meters one of the guys gave me lo those many years ago.

Re: [Elecraft] P3 "Point and Click"

[donovanf]

Hi Jimmy, 


I agree, point and click is a desirable feature, and shouldn't be 
difficult to implement via a mouse connected to the P3 USB port. 



Since your option doesn't exist (at least not yet), suggest you try 
my method which actually exists and works very well

Frank, 

You are drinking the cool aide. With the mouse click option you can tune all 
over the band quickly, sampling all kinds of signals in the time it takes to 
retune one new station. I complain about this at Dayton every year and am 
always told it’s not necessary. It’s not necessary any more than the P-3 is 
necessary but it sure would be a nice feature.

Re: [Elecraft] P3 "Point and Click"

[George Thornton]

I have used both.  I much prefer the P3.

The LP-Pan is tricky to set up and configure, and computers can be balky and 
unreliable.  Adjustments can be tricky and counterintuitive, and require 
specialized knowledge of how the particular program works.

The P3 is a plug and play device.  Adjustment is via various labeled tuning 
knobs and becomes pretty easy with a little practice.

In fixed mode the P3 can easily and directly tune to an interesting point on 
the band.  Just rotate the knob to bring the cursor into position and press the 
button.  Just as fast as a mouse.

Mike,

It does not include the P3, but there is a diagram for the rest on page 
5 of the KAT500 Owner's Manual.
Connect the P3 and K3 as shown in the P3 manual, These connections are 
independent of the rest of the K-line connections.

Re: [Elecraft] Full kits,

[George Thornton]

Constructing my old K2 was one of the most fun and challenging things I have 
done with electronics.  Before that I built a few things long ago with Heathkit.

Top end modern transceiver technology has moved beyond the K2, which is why 
Elecraft did a complete redesign with the K3 and K3s.   The K2 is a nice rig, 
but the K3s is so much more.

Modern electronics is all about miniaturization.  Nearly all the components are 
smaller, they have to be installed at the surface instead of via through-board 
solder holes.   The result is that you can now create transceivers that have 
top notch performance yet fit in the palm of your hand.  Witness the K3s and 
K2s.

To work with miniaturized surface mount components you need specialized 
equipment and specialized skills.  A simple $100 soldering station and some 
rework tools is no longer good enough for this kind of work.  There are 
relatively few amateurs who could or would tackle a kit where the great 
majority of the components are tiny and surface mounted.

I imagine Elecraft could re-engineer the K3 with non-surface mount parts.  I 
imagine the box will have to be a lot bigger.  Same performance?  Perhaps, 
perhaps not.  That will be a significantly different beast.

I think the added cost of re-engineering would probably make the kit 
prohibitive.

There are still kits around, and smaller projects are still reasonable using 
traditional construction methods and parts.  However, the era of 
solder-your-own kits is definitely in decline.

Or we could all lease some equipment and learn how to surface mount.

Re: [Elecraft] OT: be careful what you open

My two cents worth (before Eric shuts this down :)

I'm getting so many emails that ALMOST have a valid address such as

Just for fun, I hit reply and the address is now:

[Elecraft] does the K-Pod work with a K3 setup with a RemoteRig?

[Gordon LaPoint]

Wondering if a K-Pod will work with my K3 when it is using the RRC to 
control a remote K3? I would like to use some of the functions on the 
K-Pod to control the remote K3, if that is possible.

Re: [Elecraft] EFHW

[donovanf]

Hi Wes, 


The WWV half wave vertical is much like the "Happy Accident 
Ground Plane" described in January 1957 QST that uses only four 
sloping radials, sloped downward 30 degrees to produce direct 
50 ohm feed point impedance. The sloped radials make them into 
radiators, hence the feed point impedance is raised to 50 ohms with 
the appropriate slope. 



The feed points of the WWV antennas are 1/4 wavelength high, but 
I'm sure the performance would be little affected by lowering it 
somewhat. 


This antenna isn't quite a balanced half wave vertical, it isn't quite 
a ground plane, and it isn't quite a sleeve dipole but it definitely 
works very, very well. 


I used a 20 meter "Happy Accident Ground Plane" mounted 50 feet 

up in a maple tree for many years when I was in Rhode Island during 
the 1960s and worked the world with it.

>From the WWV site: 

The WWV antennas are half-wave vertical antennas that radiate omnidirectional 
patterns. There are actually five antennas at the station site, one for each 
frequency. Each antenna is connected to a single transmitter using a rigid 
coaxial line, and the site is designed so that no two coaxial lines cross. Each 
antenna is mounted on a tower that is approximately one half-wavelength tall. 
The tallest tower, for 2.5 MHz, is about 60 m tall. The shortest tower, for 20 
MHz, is about 7.5 m tall. The top half of each antenna is a quarter-wavelength 
radiating element. The bottom half of each antenna consists of nine 
quarter-wavelength wires that connect to the center of the tower and slope 
downwards to the ground at a 45 degree angle. This sloping skirt functions as 
the lower half of the radiating system and also guys the antenna 

As a side note, several years ago when my late wife and I were still traveling 
around in an RV we were near Ft. Collins. As I have done with other stations I 
telephoned the site and asked whether I could get a tour. The NIST guy was 
incredulous and said that no way did they give tours. I said, pity, I'm an 
engineer and ham and am disappointed. He thought for moment and then said, 
"Actually, we have a contractor doing some work here and the gate is unlocked. 
If you were to drive in and look around you wouldn't be bothered, but please 
stay in your car." So we did. The WWVB antenna was pretty impressive, but 
nothing like NAA in Cutler, Maine.

Re: [Elecraft] P3 "Point and Click"

[James Walker]

Frank,

You are drinking the cool aide. With the mouse click option you can tune all 
over the band quickly, sampling all kinds of signals in the time it takes to 
retune one new station. I complain about this at Dayton every year and am 
always told it’s not necessary. It’s not necessary any more than the P-3 is 
necessary but it sure would be a nice feature.

Re: [Elecraft] P3 "Point and Click"

Hi Ed, 


Try operating your P3 in fixed spectrum - tuned VFO mode (FixMode). 
You simply turn the K3 dial to "point" the VFO Cursor to the signal 
of interest displayed on the P3. 


Its very fast, faster than point and click with a mouse

Hook up you want for the K3, KPA500 and KAT500 is
shown in the KAT500 manual.

The P3 manual shows the K3 to P3 connection.

If you don't have the manuals, ALL of them are
available for download at the Elecraft site.

Re: [Elecraft] EFHW

[Charlie T, K3ICH]

Anybody got any idea about using a ¼λ of light weight 300Ω twin lead
feed line to a ½λ vertical wire?

This might alleviate the HI Z feedpoint and effectively make an end fed
(bent) ¾ λ Zepp.

So, for 20 Meters, roughly 16 feet of 300Ω connected through a 4:1 balun
at the radio, and  33½ feet at the other end up in a tree or pole.

The down side is that it would be a single band antenna and maybe a tad
cumbersome for 40 M, requiring about 33 feet of twin-lead strung out but
probably NOT laid on the ground.
There IS such a thing as shielded twin-lead that might be OK on the ground,
but it'd be too much extra weight for a portable set-up.

I can vouch for the EFHW.  It works great.  I built a parallel tuned

several times on 20 meters feeding a 33.5 foot vertical wire.  I use about
4 10 foot radials, which is probably overkill, and run it through a good
choke and it has been a great performer.  I have also used this box to feed
a 20 and 40 meter halfsquare.  I have ran 500 watts through both the half
square and the 20 meter EFHW with no arcing and an SWR  < 1.5 and a
reactance of 3 or 4.  No problems, works great.

The only issue I have had is that the EFHW tends to be a little bit noisier
than a traditional vertical, but I can put this antenna up and operate in
less than 10 minutes so it's worth the small amount of extra noise.

Re: [Elecraft] K3S and Heil PR10

[Thomas Donohue]

Hi to all:

I apologize for the late response. I am using a K3S and Heil PR10 here and had 
the same problem as was noted in the original post. I have found that the PR10 
will only work correctly using the HP input in the Mic settings. I use a mic 
gain setting of 12. I posted a note on this problem a while back and Don 
provided the correct response and my setup has worked FB ever since, and have 
been getting excellent audio reports on the air, which is the real test of the 
settings. I’ve had a number of exchanges with Heil re their recommendation of 
the LH setting for the PR10 and never was able to change their mind or resolve 
the issue. Just my two cents for what it’s worth.

 Best 73,
Tom/W1QU

Hi all,

While Ed AB8DF is on vacation I am stepping in until his return in 1 week to 
keep this great thing going and growing.

Today was a good day as I worked 2 stations from my qth in Manitou Springs, CO.
I am running a K3 at 5 watts into an end fed half wave up about 30 feet.

I worked:
N5GW  GENE in Vicksburg, MS
W5RESLARRY in Haileyville, OK

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.

wire cable for the KX3?  I wish to make up some cables for outboard straight
keys and bugs.  I would solder either a 3.5mm mono or 1/4" mono in-line jack
to accommodate the external key.

TNX fer any help es 72
