Wes,

Could you please summarize major points associated with your “aggravation and

[Elecraft] P3TXMON VSWR Measurement Accuracy

[Robert Nobis]

I am having a VSWR measurement accuracy issue with my P3TXMON.  I have a 
calibrated VSWR tester that indicates my antenna and feedline VSWR is 1.05:1. 
When I connect the P3TXMON and transmit, the PS display shows my VSWR is 2.0:1 
into my feedline and antenna. 

I also tried testing into a dummy load. The VSWR tester shows a VSWR into the 
dummy load of 1.01:1, whereas the P3TXMON shows a VSWR of 1.29:1.

Power level readings on the P3TXMON are within 5% of measured power levels 
using a power meter, so the P3TXMON is reasonably accurate measuring the 
transmitted power.

In reviewing the P3 manual, I do not see any methodology for calibrating the 
VSWR measurement accuracy for the P3TXMON.

Any suggestions on how to calibrate the P3TXMON for better measurement accuracy?

Thanks and 73,

Re: [Elecraft] P3TXMON VSWR Measurement Accuracy

[Robert Nobis]

Don,

Thank you.  I tested separately. When using the P3TXMON, the calibrated tester 
was not in the transmission path.  I actually did what you suggested in your 
second paragraph.

As another test, I borrowed another ham’s Elecraft W2 SWR meter.  I replaced 
the PSTXMON with the W2.  The readings using the W2 software utility were close 
to the readings from my tester, about 1.08:1. Significantly, different than the 
reading form the P3TXMON of 2.0:1.

73,

Bob

Re: [Elecraft] P3TXMON VSWR Measurement Accuracy

[Robert Nobis]

Wes,

The 1.01 is what the reading indicated. It could easily be higher. Even if it 
were 1.1:1 it is significantly different that the 2.0:1 reading of eh P3TXMON.

Re: [Elecraft] K3 Digital Voice Mode - our future?

[Robert Nobis]

Don,

To a certain extent, I agree with you. I also do not like proprietary 
technologies. However, if you look at the history of ham radio, many of the 
products and technologies we use today started out as “proprietary” 
technologies. Also, much of the history of ham radio is based on experimenting 
and trying new technologies and techniques. 

At least one of these digital technologies, DMR, is no longer really 
proprietary. There are at least 20 manufacturers of DMR radios, worldwide.  
True, DMR was not originally developed for use by hams, but it clearly is a 
product technology that many hams are now using on the VHF and UHF bands, even 
though I doubt we will ever see DMR on the HF bands.

I suspect nearly all commercially manufactured equipment for the ham radio

Re: [Elecraft] Unplugging the radio to protect it

[Robert Nobis]

Peter,

When I am away from home, I disconnect all antennas and unplug my power strip. 
When home I leave everything connected 24/7, except when there is a storm or 
threat of a storm. Then I disconnect antennas and my mains power strip. 

If that is Kenwood’s approach to customer service, I am glad I do not own any 
of their equipment.

Re: [Elecraft] K3 Voltmeter calibration ...

Joe,

How long is your power cable from the RS-35A to your K3, and what gauge wire is 
used?  You could easily drop 0.2 volts in the cable depending how long it is 
and the gauge of the wire.

Re: [Elecraft] Upgrade to KIO3B?

[Robert Nobis]

Joel,

I am using the TASCAM US-366 with both my K3 (dual receiver in diversity mode) 
and KX-3. I am running multiple instances of WSJT-X (rev 1.6). The TASCAM 
US-322 should work well also. Both are available at Amazon.com. TASCAM provides 
drivers for OS-X.

I believe newer models of these are the US-2x2 and US-4x4.

You might be correct with your statement “Sonar U7 will not enable the buttons 
and volume adjustment in OS X”.  I do not see any drivers for OS-X listed on 
the ASUS web page for the U7, nor does their manual indicate compatibility with 
OS X.

[Elecraft] KIO3B Install

[Robert Nobis]

I received the KIO3B upgrade kit for my K3 yesterday. Installation and setup 
was straightforward.

This was nearly a “plug-and-play” setup. I was up and running WSJT-X (v1.6) on 
OS-X (Mac) after minor adjustments to the audio levels, and had my first JT65 
QSO within 35 minutes of starting the installation.

Decode performance appears to be just as good, if not better than my external 
TASCAM US-366.  I will have to run this for a few days to see how well it 
decodes low level signals (-23 to -25dB) on JT65.

Also the sure helped to reduce my rat’s nest of cables.

Happy New Year.

Ian,

I have the same issue with my K3 and WSJT-X. Great care must be taken when 
making the Tx power adjustment, and it is far too easy to significantly change 
the ALC level with the slightest movement.

Re: [Elecraft] K3S and WSJT-X

[Robert Nobis]

Bob,

I have already tried that and several other setting levels. The issue, I 
believe, is that the PWR slider on  WSJT-X is very sensitive. A very small 
movement results in a big swing in actual power.

Re: [Elecraft] K3S and WSJT-X

[Robert Nobis]

Bob,

Yes, I also use the PWR slider bar to adjust the number of bars on the ALC 
indication, after I have adjusted the Line Gain on the K3.   And, yes, the 
actual transmit power output form the K3 is adjusted by the Power Level nob on 
the front panel of the K3.

My issue, is that the PWR slider on WSJT-X is extremely sensitive, but I have 
been living with this.

Re: [Elecraft] Noise from LEDs

Hi John,

Possibly the undercounted LEDs or their power supply are defective and should 
be replaced.  I have about 30 LED light bulbs of various types in my house and 
I have not experienced any issues with an increase in the noise floor.

Re: [Elecraft] Noise from LEDs

[Robert Nobis]

Ron,

I have had two CFL’s fail that were well beyond a “puff of smoke”. Both were 
actually melted and charred black. They were from two different manufacturers. 
I also have had CFL’s simply quit after a few years, and the base of them was 
brown from overheating.

That is part of the reason why I converted all bulbs in my house to LED.

Re: [Elecraft] Balun Questions

[Robert Nobis]

I have used RG303/U for chokes.  A bit smaller diameter than RG400 (0.170 
versus 0.195 inches). RG303/U has a solid copper center conductor that is 
silver plated.  The shield for RG303 is also silver plated copper. The jacket 
is Class 9 Teflon. Also the dielectric material is teflon.

After reviewing specs from several manufacturers, the “recommended” minimum 
bend radius for RG303 and RG400 is essentially the same at 1.0 inches.

Re: [Elecraft] Balun Questions

[Robert Nobis]

Mel,

I have seen comparable specs on RG303 versus RG400, however, some cable 
manufacturers have specified a larger bending radius for both cables. Not sure 
why?

I wonder if anyone has actually run tests of coax showing the real impact of 
bending with a small radius, comparable to what one would see in a typical 
common mode choke?

Re: [Elecraft] Balun Questions

[Robert Nobis]

Hi Guy,

Thank you.  It is interesting that the ANSI test is based on physical “outer 
surface" deformity, rather than electrical (rf) performance. Although there is 
probably a degree of correlation between physical deformity and electrical (rf) 
performance. I agree the ANSI spec outlines a rather crude test. 

The data I provided came from several manufacturers of coax. I just wanted to 
point out that the manufacturer’s specifications for both RG303 and RG400 are 
the same at a 1.0 inch static bending radius. They did not indicate how they 
came up with these specifications. I believe there is plenty of margin in these 
specified values that may be required for use in military applications, since 
both cables are MIL spec rated. However, for ham radio purposes, I believe 
these specs can be safely ignored, within reason. Although, I probably would 
not try to bend either RG303 or RG400 any tighter than maybe 0.40 to 0.45 
inches. 

I have used RG303/U because that is what I had. If I had RG400/U, I would have 
used that. In my case, I have seen no measurable performance issues with the 
tightly wound chokes that I have made with RG303/U.  If care is taken in 
winding the chokes, I feel either type of coax will do the job. Maybe if I find 
some RG400/U at the next hamfest I attend, I will buy some and try it. I could 
then compare results.

It would be interesting to do some actual tests of the electrical impact of 
bending coax at radii needed for 2.4 inch OD cores, either single or stacked.  
Possibly some type of TDR test could be done to see if any deformaty would 
impact performance of the coax used in chokes, over the HF ham bands.

Again, thanks for sharing your insight and experience.

73,

Hi Bob McGraw,

I agree, except on one point: I’s say 90%, rather than 75%, of the stuff we use

[Elecraft] Best Coax for Jumpers and Interconnections for SO2R operation with K3 & KX3

[Robert Nobis]

I am in the process of setting up my shack for SO2R operation with my K3 and 
KX3.  Just wondering what the best coax type to use for jumpers and 
interconnections within the shack?  I want to make sure I have the best 
possible isolation between the two rigs.

Jim,

Thank you. I have heard of Davis RF BuryFlex, but have not seen it offered by

concur with using Amphenol connectors. 

Thank you.

Thank you. RG223 looks like reasonably good cable.  Not sure about LMR-240.  I

Re: [Elecraft] OT: K3 and High Tension Wires

[Robert Nobis]

I have a 300KV distribution line about 0.5 miles from my QTH, and have not had 
any significant issues. About every month or two I walk along two miles of the 
power line with my KX3 checking for increased noise on various bands that I 
normally use. Only once in eight years did I hear anything and it was only 
about 3 to 4dB above my normal noise levels. A week later I checked and didn’t 
hear it. Could have been the power line or could have been something else.

Re: [Elecraft] Operating temperature range ( second attempt)

You should directly contact the Elecraft factory for this. However, as I 
recall, the K3 and KX3 are designed to operate over an operating temperature 
rating: 0 – 50 °C.

Re: [Elecraft] What's best Soundcard Interface for KX3

[Robert Nobis]

For portable operations with my KX3, I use the SignaLink USB, mainly because of 
its small size.  There are better performing sound cards, but for compactness 
and ease of use the SignaLink works for me when I travel.

Re: [Elecraft] What's best Soundcard Interface for KX3

[Robert Nobis]

George,

Many laptops do not have a good quality built-in sound cards. Their performance 
for very weak signals typically is not as good as using an external sound card. 
 You might want to test your internal PC sound card before you go to Brazil. If 
your internal sound card is able to consistently decode JT65 signals at levels 
below -19dB (for example -20 to -26 dB) it is probably acceptable.

You might wish to review Jim Brown’s (K9YC) Tutorial on sound cards:

Re: [Elecraft] What's best Soundcard Interface for KX3

[Robert Nobis]

George,

That is great. -24 dB is good for a built in sound card. By the way what 
version of JT65 are you using?

Note that your transmit signal level is usually critical for JT65 and JT9. 
Also, I always use VOX to key the transmitter.

Re: [Elecraft] What's best Soundcard Interface for KX3

[Robert Nobis]

George,

Not sure how to set up VOX using an internal sound card.  For use with my 
SignaLink USB, I simply adjusted the output level of the sound card until it 
properly keyed the transmitter.  

Also Chapter 6 in the Elect KX-3 manual covers VOX setup. See page 66.

I am also using USB rather than Data mode for decode with WSJT-X v1.7.0 dev.  I 
have been able to consistently get decodes down as low as  -26 to -27dB.

Re: [Elecraft] How does one get Elecraft's attention?

Ron,

The Elecraft people are normally very responsive. However, they are also very 
busy. Also, I believe they only have one person that is very knowledgeable with 
the K3/0 Mini. He may be temporarily away from the office. Also, not sure how 
quickly you expected someone to get back to you as you didn’t explain that 
small detail.

Andy,

I also order one of these nearly one year ago, and still have not received it. 
I recently sent them an email, and they apologized for the delay and referred 
me to their web page for details. Unfortunately the details on their web page 
are a bit vague and offer no information on when these will actually ship.

Hi James,

I use a TASCAM US-366 with my Mac and have the sample are set to 48,000 Hz with 
no issues running WSJT-X versions 1.4 and 1.5. I use VOX control. You might 
have to go in and week the K3 VOX Gain and Line In Gain menu settings, however.

[Robert Nobis]

I am no longer able to operate portable, so am selling my factory built

updated with the latest firmware (MCU 2.76/DSP 1.50) at the Elecraft factory. 
Used on two field trips to Japan. No smoking environment. The equipment is 
configured as follows:


KX3-F Factory Assembled KX3 (ser # 7486 )
KXAT3-F Internal 20W ATU
KXBC3-F Internal NiMH charger with Real-time clock
KXFL3-F Dual Passband Roofing Filter
KX3-PCKT Accessory Cable Kit

Re: [Elecraft] OT: 2017 Chevy Silverado 1500 power outlets

[Robert Nobis]

Hi Vic,

Just wondering, what is the probability that the ground cable would become 
either partially or completely disconnected?  In the unlikely event this might 
happen, simply put an appropriately rated fuse in the ground line, in addition 
to the one in the positive voltage line.

Re: [Elecraft] K3 badpass issue

[Robert Nobis]

You need to setup each band. The setup for each band is independent, and the K3 
remembers the setup for each.

Re: [Elecraft] Antenna switches

[Robert Nobis]

I agree, isolation is the most important factor for antenna switches. However, 
I wouldn’t use a switch unless it had at least 60dB of isolation in the HF 
band, even with Tx power of 100-watts.

Re: [Elecraft] Antenna switches

[Robert Nobis]

I use Diamond Antenna Switches originally purchased in Japan with good results. 

See http://www.diamond-ant.co.jp/english/amateur/equipment/equipment5_swi.html 
. The claimed isolation up to 200MHz 
for the two-port CX210A switch is 70dB. I have not actually measured the ones I 
have.

These are available form DX Engineering for about $50.00

Oh, I do not have any connection with either Diamond Antennas or DX Engineering.

[Elecraft] JARD Technical Standard Certification Number for K3 or K3X

[Robert Nobis]

I am planning a trip to Kagoshima, Japan in a few months and am applying
for a reciprocal license to operate in Japan. Does anyone know if the K3
and/or K3X have JARD (The Japan Amateur Radio Development Association)
Technical Standard Certification Number? This is required for operation of
the rig in Japan when operating under a reciprocal license.

73,


Bob -  N7RJN

Re: [Elecraft] JARD Technical Standard Certification Number for K3 orK3X

Jim,

I assume it requires a business decision. There may not be sufficient
enough customer base in Japan to warrant the cost of Elecraft getting the
certification for the K3 and KX3.

Re: [Elecraft] JARD Technical Standard Certification Number for K3 orK3X

[Robert Nobis]

Jim,

I suspect the issue is that Elecraft simply has not pursued getting the
certification. Possibly the ROI doesn’t justify doing this.

At any rate, there is a procedure for an individual to get a temporary
certification for use while traveling in Japan.

[Elecraft] Audio Amplifiers without Pin One Grounding issue for us with the K3

[Robert Nobis]

I also use my K3 to listen to SW broadcasts and am looking for an audio
amplifier that is immune to RFI and does not have the pin one grounding
issue for the input/output connectors. I prefer something in the range of
10 to 25-watts of power to drive my speakers. Does anyone have any
recommendations?

Thank you and 73,

Hi Rick,

Thank you. When I ordered my K3 I ordered the TCXO option, as I was
planning on eventually trying the digital modes. Just wondering, what
software do you use for the JT modes?

[Elecraft] Best VGA switch for use with P3 and a computer with a Single Monitor

[Robert Nobis]

I did a search of the reflector and didn¹t see anything covering this.  I
want to use a single computer monitor for use with my P3 and my computer.
I only have room for one computer monitor, and want to be able to switch
between my PC and the P3.  Does anyone know of a good VGA switch for this
that has good RFI immunity?

I only need to swith the monitors, not a keyboard and mouse, so the normal
KVM switch is probably overkill.

Thanks and 73,


Bob  -  N7RJN

Thank you. Unfortunately, my monitor only support one input, and that is
VGA.

Re: [Elecraft] Best VGA switch for use with P3 and a computer with a Single Monitor

[Robert Nobis]

I want to thank everyone for responding to my question on a VGA switch.

I have ordered a 2-Port VGA Monitor Switch Box from Monoprice that looks
like it will do nicely.  Price = $9.20 each.

http://www.monoprice.com/Product?c_id=101&cp_id=10106&cs_id=1010601&p_id=54
&seq=1&format=2

Here are the specs:

Switches one VGA monitor between 2 computers.
Standard HD15 15-pin female connectors for VGA video/monitor. (all
connector are female ports)
Fully shielded metal case.
Anti-skid rubber feet.
No power required.
6"w x 2 1/2"h x 4”d

They also have a double shielded VGA cable with ferrite cores at each end.

[Elecraft] Proper Setup of K3 with SignaLink USB for running WSJT-X on a Mac

[Robert Nobis]

I am trying to setup WSJT-X for JT65 operation on my K3 and Mac but can't seem 
to get the program to work. My audio card is a SignaLink USB.

When I try to configure WSJT-X to interface to my K3, I always get the message 
"Open Rig Failed". 

Does anyone have any suggestions on the proper setup of the K3 as well as 
WSJT-X?

Here is my K3 setup:

K3 CONFIG settings:
 AF GAIN HI
 AF LIM   nor 030
 LIN OUT nor 075 
 PTT--KEY   OFF-OFF
 RS23238400 b
 SPKRS   2
 SPKR+PHNO

K3 MENU Settings:
 MIC SEL Line In 
 MIC+LIN Not APPL(I can't change this)

Controls:
 CMP   0
 MIC  MIC LINE 20
 SQUELCH  0
 RF GAIN 50% 
 MODE USB
 NB   OFF
 NR   OFF
 NTCH   OFF
 VOX OFF
 AGC AGC-F
 ALT  OFF 
 PWR50 Watts 
 
On the SignaLink USB I have the Tx and Rx gain set for 50% and DLY set to 0.

Thanks and 73,

Jim,

Thank you.  This might be my issue. Here are the settings in my ini file:

 CATdriver=/dev/rig
 CATport=/dev/ttyUSB0
 CATportIndex=9

How were you able to determine your actual USBSERIAL name and location?

Re: [Elecraft] Proper Setup of K3 with SignaLink USB for running WSJT-X on a Mac

[Robert Nobis]

JIm,

Thanks, I found the USBSERIAL name and modified the INI file. I changed my 
settings to the following:

CATdriver=/dev/tty.usbserial-AD02DW0Z
CATport=/dev/tty.usbserial-AD02DW0Z
CATportIndex=9


I have now been able to transmit, although I noticed that I don’t get any 
readout on the ALC - Not even one bar. Must still have something set wrong.

[Elecraft] Reliable DC Power Supply for K3/P3

Re: [Elecraft] Reliable DC Power Supply for K3/P3

[Robert Nobis]

Everyone,

Thank you. It looks like using an Astron supply is the way to go.  I will
probably go with the RS-50, as I also have a Yaesu 2M/70cm rig to power.

Incidentally, this mailing list was one of the major reasons why I decided
to get the Elecraft K3/P3 instead of competing products made in Japan. I
have found the members of this list quick to respond to questions from
others, with great answers.

Again, thank you.

73,

Re: [Elecraft] PC laptop for K3/KX3 digital modes

Dave,

If you have Mac experience and still have a Mac, you should use it. The
Mac is a very stable platform for Windows when you run Windows under
VMWare Fusion on an Intel based Mac.

See http://www.vmware.com/products/fusion/

[Elecraft] Multi Turn Loop Antennas Using SGC Smartuner

[Robert Nobis]

Does anyone have any experience using multi-turn loop antennas with SGC¹s
(or other) antenna tuners?

SGC describes these in their book Smartuners for Stealth Antennas.  See
http://www.sgcworld.com/Publications/Books/stealthbook.pdf

I have a K3 and live in a HOA community with significant antenna
restrictions, so I am looking for a small antenna.

Wes,

I am in Arizona and am using an N6BT Bravo-5a vertical and it works well.  I 
have worked over 1500 stations since installing the antenna with about 30% of 
these being DX in Asia, Latin America and Europe.  Could I do more DX with a 
three element beam at 60+ feet? Probably, but since I live in a community with 
an HOA that has restrictions, this is not an option for me.

Re: [Elecraft] [K3] Sound card suggestions - TASCAM 366

[Robert Nobis]

A few weeks ago, my wife asked me what I wanted for Christmas and I said a 
TASCAM 122 USB Interface.  Instead I received a TASCAM 366. She checked on line 
and the 122 was listed as discontinued and replaced by the 366, so she ordered 
the 366.

So now I have a TASCAM 366, which has significantly more capability that I 
really need. Anyway I will try to use it with my K3 for JT65 and JT9 operation. 
I am wondering, however, if anyone on this reflector has any experience with 
the 366 and could provide some hints for proper setup and operation.

Thanks and Merry Christmas.

73,
