Re: [Elecraft] Field Day

[Jim Brown]

Bill,

I understand the intent of the statement in the FAQ. My point is that 
these clarifications should be part of the FD RULES, not an FAQ. To me, 
an FAQ is answering questions raised because the Rules are poorly 
written or incomplete. If I were running things, I would ban all FAQs 
and tell the author(s) of the basic document(s) to finish their job!


When I first did FD in 1957, we logged on paper and kept paper dupe 
sheets. One guy operated, a second kept the log and the dupe sheet. The 
rules have not changed much since then, and to some extent, those days 
are still the mindset of both the League and many club participants.


BTW -- my question about the monitor was rhetorical, and I don't agree 
with your logic about it. It's part of the computer's user interface -- 
we humans can't operate the computer to control a radio without it.


The good thing about requiring true backup power for the computer causes 
us as hams to think more seriously about running in emergencies. The bad 
thing is that independent of the mains AND not powered by a generator is 
that most laptops now need 16-20V at their power socket, it's hard to 
find QUIET DC-DC converters, and it probably takes more power to run the 
laptop than to run a KX3.


There's the interpretation of another contesting rule that is the basis 
of "split site" operation during Sweepstakes. Two operators run one day 
from their own QTH, then trade QTHs for the second day. This was 
originated by our own big club, NCCC, and has since been adopted by 
other clubs. The RULES says that 1) each operation needs to use a 
different call (usually a Club call) and 2) a TRANSMITTER may be used 
with only one call during a contest. This means four calls and four 
transmitters. Starting out in broadcasting a few years after that first 
FD, I've always viewed a power amp as part a transmitter, but the Rules 
are not interpreted that way -- they apply it only to the transceiver!

Re: [Elecraft] KX3 - Missing ATU DATA Menu Item

[krug261--- via Elecraft]

 With thanks to Dan, K9GDQ, I now now I realize why I only noticed the "issue" 
this last time I used the KX3. The only time I look at the ATU DATA menu 
setting is when I take the unit remote. By definition, that means it is - for 
me - without the amp connected. So PA MODE defaults to OFF, and ATU DATA is 
there. This last time is the first occasion for me to look for the menu item 
when connected to the amp, so the ATU DATA menu item is suppressed.

The KX3 ATU appears to be functioning properly. It is connected to the KXPA100 
with its own ATU, but I tuned the KX3 ATU with the KXPA100 in Bypass. All seems 
well except for the missing menu item. So, what is the easiest/safest means of

1) Download my last configuration file?
2) Hit the "Send All Firmware to KX3" button in the KX3 Utility?

Re: [Elecraft] Questions about KX2 possible purchase

[Bill Lederer]

I bought the KX2 with all options save the Key paddle. I also got the
antenna and the bag. This included two lengths of ground wire.

Haven’t done sota or much remote yet. I would take handfuls of various wire
lengths in addition to the ground wire.

I did operate it from the Titan missile museum with their 80 foot Discone.

High recommend this rig

I’m not a lawyer nor do I play one on television, nor did I stay at a Holiday 
Inn Express last night….  ;-)

It seems to me that the ’spirit’ of the FD rules is that anything that impacts 
the transmission/reception/interpretation of RF communications cannot be on a 
commercial power source if the site is going to claim ‘emergency power’ as the 
power source.

So if a Local Area Network is installed to pass data between stations at the 
site for logging purposes or coordination of transmissions, or is involved with 
digital signal modes, or if there is  computer equipment, monitors, or 
ancillary equipment is used as part of the system to process information as 
part of the overall operation, then they all must be off commercial power if 
‘emergency power’ is to be claimed as the power source.  A Flex system that 
uses the LAN to communicate between Maestro, Antenna Genius, PGXL 
Amplifier,etc.  may only be running CW and SSB without a PC would have to have 
that LAN on emergency power as the LAN is integral to the setup/operation of 
their communications equipment.  If a laptop is running SSDR and has an 
external monitor, both devices would need to be off commercial power.  If a 
laptop is logging contacts or being used for digital modes, it and anything 
else attached to it would also need to be “off the grid” to claim emergency 
power status.

The bottom line is that those that are involved with the design/installation of 
a field day site shouldn’t be looking for ‘exceptions’ to the rules but ask 
themselves whether their site setup meets the ‘intent’ of the rules. 

Or, to put it another way, if the site did have a commercial feed available and 
that feed was lost due to a power outage, would the site be able to continue 
operating regardless on the existing sources of power that they’ve installed at 
the site?  If the answer is “no” (e.g. they need to rewire/reconfigure to 
accommodate the loss of commercial power to keep operating as intended), then 
that site doesn’t qualify as running on emergency power until such time as they 
can indeed operate from start to finish without interruption.

FWIW,

[Elecraft] Second Beta of New WSJT-X Posted

[Jim Brown]

K1JT announced on the WSJT-X reflector that the second beta of the new 
release is posted on the WSJT-X website. There are bug fixes, and a few 
tweaks. Most important (for me, at least) is that Hold TX freq is no 
longer un-checked when you switch modes.

Re: [Elecraft] KPA1500 PF Keys

[Jim McCook]

Jim, I just programmed my PF keys in the KPA1500 for fan speed 0 or 1.

Connect the USB cable to your computer from the KPA1500
Turn on the amp
Open the KPA1500 Utility program
Click on Configuration, then Edit Configuration
Click on the PF Keys tab at top
To set PF1 to fan speed 1 type *^FC1
*To set PF2 to fan speed 5 type *^FC5
*Click OK

Now press/hold PF2.  Fan speed should be 1.  PF2 should ramp up to 5.

The Programming Reference isn't so bad if you scroll down to the 
function you want to change.  It's pretty well spelled out.  This 
particular function, Minimum Fan Speed, was explained on page 24.

Re: [Elecraft] Questions about KX2 possible purchase

[Don Wilhelm]

Doug,

The battery and tuner are 'options' and do not come with the basic KX2. 
This is typical of Elecraft - if you don't need it, you do not have to 
buy it, they do not include it as part of the basic package.  The 
microphone and paddles are also not part of the basic package.


Is your end-fed antenna tunable with a capacitor?  If so, then no tuner 
is required - otherwise yes.


If you want to operate 20, 17 and 15 meters with an antenna that is 
short and portable, then the AX1 may be the thing for you.  If you are 
planning operation from the home station, use resonant antennas mounted 
higher for better results.  The AX1 (and AX1E for 30 and 40 meters) does 
a good job when you have to set up quickly and operate in a portable 
situation.  The KX2 tuner is required with the AX1 antenna.


On your end-fed antennas - you do need a counterpoise of about 0.05 
wavelengths (see the W8JI experiments).


A just as good portable antenna is a BNC to binding post adapter 
connected to the KX2.  A 58 foot length of wire and a 27 foot 
counterpoise will be a good performer for 80 through 10 meters (no 
feedline).  Yes, you will need the KX2 tuner with that arrangement.
The counterpoise can be laid on the ground and the radiator thrown over 
a limb or tall bush.  One of the KX2 Field Testers who operates mostly 
SOTA has determined that those lengths work well.


I can't answer about your 80 and 40 meter end feds, if they are tuneable 
with a capacitor, then you do not need the tuner, but if they have UNUNs 
which tie the bottom of the primary and secondary together, they will 
use a part of the feedline for a counterpoise.   The counterpoise for a 
tuned end fed antenna needs to be only 0.05 wavelength long (see the 
W8JI experiments).

Don W3FPR

My questions are, does the $829.95 price include a battery and tuner. The
web site isn't clear. If a battery is included, is a second one a wise
purchase?
If the tuner isn't included, how necessary is the tuner (I have an end fed
80 and am building an end fed 40).
Is the AX1 worth it for just 20, 17, 15?
What else is not included that I should be considering?

I want to set PF1 and PF2 to set Fan Min Speed to 1 and 5. I can't find 
anything in the manual to do that. The only thing I see refers me to the

other products, I can program them from the front panel.

Are you sure about that, Jack? I've seen exactly the opposite statement 
(not directly from ARRL, but by someone quoting ARRL).

Re: [Elecraft] consumer-grade audio equipment / RFI suppression,

[HP]

Last summer I kept hearing noise bursts on 6 meters on my K3 that seemed to 
follow a beat - 
Neighbors behind me were playing "music" with lots of bass notes on outside 
speakers. 
I went out with my trusty Icom R10 handheld rx and sure enough the noise bursts 
coincided with the bass beats . It was oscillating on 6 meters on bass 
peaks That was only one afternoon 
and apparently it blew itself up -or they re routed speaker leads or whatever 
-still hear the audio 
from time to time quite a bit lower level but no 6 M spikes.

Most end-fed antennas need a COUNTERPOISE to serve as a return for the 
current (and the field) produced by the antenna. An earth connection is 
NOT a good counterpoise, because the earth is really a big resistor, so 
it burns most of the transmitter's power if that's the only 
counterpoise. Instead, smart operators provide some intentional 
counterpoise connected to the BNC shield, like multiple radials or a 
single wire running in some direction other than the antenna. If the 
wire or the radials are laying on the ground, they will couple some of 
the earth's resistance and burn some TX power. This can be reduced by 
elevating the wire or the radials. When operating portable, I've draped 
a single wire counterpoise over the tops of low brush.

My questions are, does the $829.95 price include a battery and tuner. The

I bought mine with the internal battery and charger, and the ATU.  That  
way, let the factory install them and check them out.



If a battery is included, is a second one a wise purchase?


I have done a few SOTA summits and many QRPTTF and the like field  
operations.  The cited 8-hours on the battery is very accurate.  I have  
found no need for a second internal battery.  You just seldom sit on a SOTA  
summit or a field event for 8 hours.  Even running at 10W, you get a good 6  
hours.


The KX2 has a barrel jack for external DC power, which it can be run off of  
in the shack, or for an external battery in the field if desired.



If the tuner isn't included, how necessary is the tuner (I have an end fed
80 and am building an end fed 40).


I would recommend it.  I have built no-tune antennas for portable use, only  
to find a higher than I want SWR once I get to the field or the SOTA  
location.  There is no electrical ground to speak of on a mountain peak, so  
an antenna will tune different there than your back yard.  The ATU is so  
convenient compared to piddling with wire lengths and radials in the field  
to get it tuned and low SWR just to get on the air.



What else is not included that I should be considering?


The KXPD2 paddles are also very convenient.  No need to haul around  
separate paddles for field operations when you have one right on the front  
of the rig.  The paddles, plus the front panel SPEED control, makes it  
snappy to change CW speed when needed.


I bought mine when first released.  It works like new, as advertised, and a  
hearty rig even for SOTA and other less-than-ideal situations.


GL with yours.

I strongly recommend the tuner for your uses.



Is the AX1 worth it for just 20, 17, 15?


That depends on what other options you can buy that best suit your plans 
for each location, and will certainly vary from one QTH to another. It's 
a very nice light weight, super-portable antenna designed by Wayne 
himself, who is a serious backpacker, but it's really designed for 
pedestrian/bicycle mobile operation.


> What else is not included that I should be considering?

Mic, paddle, computer, one or more cable adapters if you want to work 
WSJT modes.


For longer operating events, one of these outboard batteries or a second 
internal Elecraft internal battery.


https://www.bioennopower.com/collections/12v-series-lifepo4-batteries

When comparing rigs, consider that Elecraft backpacking rigs include a 
very good receiver and preamp, and draw FAR less current on receive than 
the JA rigs -- ~150mA for the KX2 and KX3, compared to 1A or more for 
the others. This greatly extends battery life. The KX2 has a built-in mic.

Re: [Elecraft] Field Day

[Jack Brindle via Elecraft]

From the FAQ:

"You must operate all transmitting and receiving equipment from emergency 
power. If you use a computer for digital modes, and/or to control or operate 
the radio, it also must use emergency power. If the computer is used only for 
logging and is not keying the transmitter, it does not need to be emergency 
powered.” 

Now this is an answer to a question about the 100 point emergency power bonus, 
but we have been told it applies to normal operation as well. The key is 
“controlling the transceiver”. If it even changes bands or causes transmission, 
then it must be operated on emergency power.

If anyone questions the charging requirements, section 6 “Miscellaneous Rules:” 
states:

"6.9. Batteries may be charged while in use. Except for Class D stations, the 
batteries must be charged from a power source other than commercial power 
mains. To claim the power multiplier of five, the batteries must be charged 
from something other than a motor driven generator or commercial mains."

Very clear.

73!

Re: [Elecraft] Field Day

[Walter Underwood]

Don’t guess, look it up.

Q. What equipment at our Field Day site must be operated off of the emergency 
power in order to claim the 100-point per transmitter bonus?

A. You must operate all transmitting and receiving equipment from emergency 
power. If you use a computer for digital modes, and/or to control or operate 
the radio, it also must use emergency power. If the computer is used only for 
logging and is not keying the transmitter, it does not need to be emergency 
powered.

http://www.arrl.org/files/file/Field-Day/2019/2019-FD-FAQ-RevA.pdf\ 


Also, batteries may be charged from commercial power, just not during Field Day 
operation. It does make sense to get a simple charger if you are going to buy a 
big battery.

[Elecraft] Questions about KX2 possible purchase

[Doug Daniels]

I'm looking at the potential purchase of a KX2. It's primary use will be
SOTA, and other hiking ops. I've narrowed my choice down to this and one
other rig. I want to make sure of what is included and what is not, and
what needs to be added to the base rig and price.

My questions are, does the $829.95 price include a battery and tuner. The
web site isn't clear. If a battery is included, is a second one a wise
purchase?
If the tuner isn't included, how necessary is the tuner (I have an end fed
80 and am building an end fed 40).
Is the AX1 worth it for just 20, 17, 15?
What else is not included that I should be considering?

Re: [Elecraft] Field Day

Be careful following this one. His suggestions will leave you in class D. Why? 
Two things - if the computer controls the radio (and it should for logging and 
sending exchanges), then it must also be run on emergency power. Second, the 
addition of a wall charger for the batteries puts you firmly into class D. You 
can charge the batteries off solar panels to remove this restriction.

Field Day at WVARA station K6EI consists of many QRP stations all running off 
battery, and all are charged by solar panels. For SSB, my 20/80 meter station 
will run the entire event from a single Marine battery (bought at Costco for 
$75). That powers K3S, P3, Computer (15” MacBook Pro) and lighting. It is 
charged during daylight by a 100 watt solar panel. By the time we break down on 
Sunday, the battery is fully charged. That solar array is a game-changer, 
turning this from a multiple battery event into one handled by a single 
deep-discharge marine battery.

Unfortunately, it appears we won’t be doing FD this year from the great vista 
overlooking the San Francisco Bay area (really a spectacular view), although we 
haven’t been told the definitive no just yet.

Be sure to read the full Field Day rules for what is legal and what isn’t. They 
tend to be rather strict.

[Elecraft] K3 configuration printing?

[w4sc]

Windows NotePad will open, and you should be able to print.  Don’t change any 
settings/info and save because if you do the K3 utility probably will not open 
if you attempt a  reload to the K3.

[Elecraft] K3 configuration printing?

[Tom Doligalski via Elecraft]

Several years ago I recall a thread about how to print out the settings used in 
the K3. Thought it might be handy to have, as I patiently await my K4 (so, 
obviously, no hurry!). 

Anyone recall how to this?  As I recall, it’s not innate to the Utility 
program.

Re: [Elecraft] [K3] KAT3 not functioning on 6m

[w4sc]

Bill

Upgrading to KSYN3A, you should run the High Power TXGAIN  Calibration 
according to the installation instructions.  Actually, I had to run the 
WATTMETER,  and BOTH the LP (5W)  and HP (50W) calibrations to “cure” the same 
issue you are observing.

Installing the KSYN3A in a K3 results in lower output on 6M when the KPA3 is 
active, i.e. the requested power is greater than 12W. When the power requested 
is less than 12W, the KPA3 is inactive (bypassed),  the output power is within 
measuremt accuracy on an external wattmeter to what is requested by the K3 
power setting control.

When the power requested is greater than 12 W, i.e. 100W for example,  what I 
have observed is at 52.000MHz the external wattmeter reads 85W, and at 
50.500MHz only 63W is realized.  There is little difference in the output power 
measured in each case with/without KAT3 tuner “bypassed” or “enabled and 
matched” at the operating frequency’s outlined above.  

It appears that this anomaly occurs only on 6M,  I don’t know if there is a 
solution or fix for the above.

K3 F/W  5.67
Load 100W 30Db attenuator
Wattmeter  HP736  with 8481 power sensor  and Bird with appropriate elements.

Re: [Elecraft] Mcu ld

[Don Wilhelm]

Paul,

Refer to either the manual or K3 Utility "Force a Firmware Download" and 
follow the instructions given there.
That condition is usually the result of a communications glitch during a 
firmware download.  Always wait until the firmware load completes before 
touching the K3 or the computer.

Re: [Elecraft] K2 distorted audio on certain freq.

[Don Wilhelm]

Mike,

This is the Weird At One Frequency (WAOF) problem.  It occurs at the 
point where the PLL and VFO frequencies cross, and that usually occurs 
near 7185kHz.


First step in the cure is to flush cut every lead in the vicinity of
RF Board U4 and the VFO - so that those small leads cannot act as an 
antenna.

Then retest.
If the problem still exists, try removing C88 (soldered on the bottom of 
U4 between pins 12 and 13).  Retest again.


If still present, remove RFC15 - again on the bottom of the board 
between U4 pin 16 and the adjacent solder pad just to the right of pin 
16 - replace with a very short jumper wire.


Good luck with it - not all K2s suffer this 'malady', but unfortunately 
yours does have the problem.


Does your noise problem occur if you disconnect the antenna?  That does 
sound like some noise being picked up by the antenna.  I have never seen 
that behavior in a K2 before, and I have repaired over 1000.

Don W3FPR

Re: [Elecraft] RTTY Problems on K3

[Jim Rhodes]

Over the years I have built all of my interfaces. Started with
optoisolators but when trying to go SO2V I couldn't make them work with the
outputs paralleled.  Now I have 2 db9 serial plug with a single 2n & 1k
resistor in each, outputs paralleled into a db15hd for the acc on the K3.
PTT is via CAT. This is the simplest solution that I have found. I use I/O
usb to serial converters with 4 or 8 ports. Enough to run everything on
rs232. Only use usb for CAT and sound. This is the least number of cables
and connections I have used, and I like how it works. Am really starting to
regret selling the house and moving into an apartment building though.

Re: [Elecraft] RTTY Problems on K3

[Larry (K8UT)]

Bill,

You could begin by breaking the problem in half - test at the output of 
the optoisolators.


Front Half - Test what's coming from N1MM and MMTTY:
Put a scope or meter on the PTT line and click [TX] in MMTTY. Does the 
line go low and stay low for the duration of TX?Put a scope or meter on 
the FSK line and click [TX] in MMTTY. Does the line toggle at 15ms RTTY 
intervals? With a meter the voltage would drop, indicating lower average 
voltage - but something would be different between RX and TX.
>If this doesn't work, first place to check is the MMTTY >Options >Setup 
>TX, "PTT and FSK" and >MISC, "Tx Port"


Back Half - Test whether the K3 is sending RTTY:
Use a clip lead to short the optoisolator PTT output to ground. Does the 
K3 go to TX?While the K3 is still in TX, use a second clip lead to short 
the optoisolator FSK output to ground. Does the TX monitor tone shift?

Subject: [Elecraft] RTTY Problems on K3


I am fairly new to the K3 but have no problems setting up N1MM and  other 
software, getting things to work properly. My problem is I  cannot get RTTY to 
send/TX. I have made a homebrew interface with  optoisolators for both the FSK 
line and the PTT line. I'm going from a  separate serial port, pins 3 and 7, 
for FSK and PTT, to the Assy(15  pin) connector. To pins 1 for FSK, 4 for PTT 
and 5 for ground.

When I run MMTTY I cannot get the rig to key. If I switch to SSB or CW  and use 
the CAT line to work the PTT, no problem. If I switch to RTTY  and try to use 
the CAT line it will not key the TX. I've tried a  variety of setting in MMTTY 
and get no TX. I have a 1000MP set up with  a similar homebrew interface and 
have no issues.

Can anyone shed some help on me?
