Re: [Elecraft] Possible phase noise question...

[Bayard Coolidge, N1HO via Elecraft]

One issue that someone obliquely mentioned in the various
replies that I feel requires greater emphasis, is that the
SignaLink USB box is, first and foremost, a sound card
and as such requires a great deal more current than a typical
USB device and should be plugged into a *powered* USB
hub. Granted, the power supplies for various powered USB
hubs are likely to be noisy (from the perspective of us hams,
anyway), and may need further treatment (chokes, bypass
capacitors, etc.). But if your SignaLink USB is plugged directly
into your laptop or desktop, know that it's drawing more current
than the USB (3.0) spec allows, and that may be a significant
contributor to the noise problems being reported in this thread.

Re: [Elecraft] Synchronized and stable GPS phase lock for KX3, K3 and XV transverters

[Bayard Coolidge, N1HO via Elecraft]

The newer Trimble Thunderbolt requires +24VDC, but some of the
older units on E-Bay, etc. may require +5VDC, +12VDC and -12VDC,
which can be obtained from a simple/inexpensive power supply.
(I used a Meanwell NET-35B). It outputs a 10MHz sine wave (which
plugs into the K3EXREF) as well as 1pps logic signal. Trimble also
makes/made an active antenna, which I also found on E-Bay, which
is a small square about 2 in/5 cm square and has an internal preamp
powered by +5V supplied on the Thunderbolt's antenna jack. I've
been running one for about a year now, and it maintains the 10MHz
to within about 30 parts per trillion, depending on how many satellites
are regularly visible - I usually see 8 or 9 in south Florida and 5-6
in the mountains of western North Carolina.

Re: [Elecraft] KTCXO3-1 TCXO 1 PPM

[Bayard Coolidge, N1HO via Elecraft]

  Is it actually that easy to install?

Yes, it is. Just remember, you really do want to use a
static mat and wrist strap whenever you open up your K3 to
work on something internal to it.

I ran with the KTCXO3-1 from the time I built my K3 two years ago,
but then added the K3EXREF and a Trimble Thunderbolt this spring.
However, should there be a problem either of the latter, I know I can
quickly and easily revert to the KTCXO3-1 as needed. It's a heady
experience to know that when I set the frequency on the K3, it's
accurate to the last Hertz - a far cry from the 75A-3 I used as a Novice.

Re: [Elecraft] K3 External Frequency Reference Questions

[Bayard Coolidge, N1HO via Elecraft]

I installed a K3EXREF and set up a Trimble Thunderbolt a few months
ago, and I've been very happy.

The K3EXREF was very easy to install - just remember that it's a very
good idea to use a static mat and wrist strap whenever you dive into
the inside of a K3. The instructions were quite clear, and since I'd built
my K3 from the kit, it was an easy procedure.

I don't have any experience with rubidium disciplined oscillators, but
I would suggest you take some time to read through the Time-Nuts
mailing list; the archive is at

time-nuts Info Page
  
 
time-nuts Info Page
time-nuts -- Discussion of precise time and frequency measurement   About 
time-nuts   
View on www.febo.com Preview by Yahoo  
  

I was able to get a lot of good information there, and although I didn't 
subscribe
and therefore don't know about any recent discussions, there is a treasure trove
of details about the use of various disciplined oscillators, including 
rubidiums.

In addition, I know that Down East Microwave has, among a lot of other things,
a distribution box for 10MHz signal sources so that you can feed the K3 from
one port and feed the LO for a transverter off of another, and they also have LO
modules that incorporate PLL/VCOs that can sync to external 10MHz references.

And, yes, it's a heady feeling to know that, at least on HF, your K3 displays
your frequency right down to the nearest Hz. There is a write-up in the K3EXREF
documentation that explains that it's a real good idea to jot down the frequency
of the master oscillator so that if your external reference fails, you can tell 
the K3
what you want it to set itself to, so that it doesn't jump to some arbitrary 
frequency.

Re: [Elecraft] A new Elecraft product?

[Bayard Coolidge, N1HO via Elecraft]

I've been running with a Trimble Thunderbolt GPSDO and the Elecraft TCXO for
over a year now. I'm in a position to keep the Trimble powered up continuously,
but I can certainly understand the angst of those who can't. It's a trade-off. 
I also
keep an old laptop running, and have Lady Heather running on it to keep an eye
on things. Do I really *need* that level of precision? Probably not, for my 
current
operational needs (ordinary/casual HF operations, no VHF/UHF transverters, 
etc.).
Bear in mind that the GPS receiver decodes the signals from the various 
satellites
that can be seen at any given time, and then generates an error signal to its
internal TCXO running at 10MHz, which then spits out both a 10MHz signal, which
we typically feed to the K3EXREF, and a 1 pulse per second square wave (which
I'd love to feed to a wall clock). The issue is the 100 second warm-up time for 
the 
Trimble's TCXO, not the GPS receiver, although the latter usually needs, like 
any
other GPS unit, a few moments to listen for, and synchronize, to satellite 
signals. 

There are a couple of system design issues inherent in this, however. First, the
Trimble requires a triple-voltage power supply: +5V, +12V, and -12V. I'm using a
cheap commodity power supply that is in itself powered from AC mains 
(117V/60Hz).
So, if I lose AC mains, I lose the Trimble, and have to hope that the K3 and 
its TCXO
will stay accurate enough while I'm operating it off of a battery. For those 
purposes,
a few Hz isn't going to get me kicked out of an amateur net, but if I were a 
MARS
member (which I'm not), it might be dicey - I'd have to do an analysis.

The third issue, which has not been touched on AFAICT, is that the Trimble (and
probably its competition) really likes to have an external antenna. In my case, 
I was
lucky to find the actual Trimble antenna (which includes a preamp), and it's 
served
me well at both of my QTHs (So. Fla. and western NC), which is a square puck
about 2 inches/5 cm on a side with a magnetic base and 25 feet of RG-174/U coax.
It works, and it was cheap on E-Bay, so I'm happy so far.

So, a potential add-on product for the K3 could involve one of the newer 
single-board
GPSDOs (e.g., Sematron GPS-1000 or one of its competitors), feeding the K3EXREF
board internally and using the K3EXREF's input port on the back panel of the K3
for its antenna port. However, I haven't even priced one of these units, never 
mind
purchased and evaluated it, much less actually attempted to install it in my 
rig. So,
far, it's just an idea or springboard for further discussion. Brian makes an 
excellent
point about the overall temperature requirements, as well as the behavior of 
the K3
running with its TCXO synchronized to a potentially unsuitable reference 
signal. These
can be tricky design issues, and I'm sure Wayne and Eric have enough other 
things on
their list to tackle at this point, without a digression into this quagmire.

Just my 20 millidollars' worth,

Re: [Elecraft] Fwd: [TowerTalk] Elecraft package for sale

[Bayard Coolidge, N1HO via Elecraft]

I realize that this topic has been beaten to death, but I wouldlike to point 
out one factoid. Down here in Florida - I'm down inthe southeastern part, and 
AK4EH is way up in the Panhandle -there have been a number of instances in 
which homeownerswere unpleasantly surprised to discover that their properties 
werebeing offered for rent (or, even, sale!) by unknown/unauthorized third 
parties.
There's been a huge upheaval in the real estate market here, generallyspeaking, 
and a lot of people have been buying properties for cashbecause they don't want 
to endure the hassles of getting a mortgage.Problem is, they're not performing 
what lawyers (and business owners)call due diligence, and end up at closing 
to discover that they'rehanding money over to someone who doesn't own the 
property. Oops.Same sort of thing is happening with rentals - folks put down a 
deposit,and start to move in, only to be faced by the local constabulary witha 
drawn firearm, at which point they realize that that great deal they goton the 
Internet was totally bogus.
So, yes, there is always room for suspicion, sadly enough, and for thereasons 
that others have voiced in this thread, as well as other reasonsthat may not 
have come to light yet.

Re: [Elecraft] K3 and HRD: MAC using VMWare + HRD, no waterfall display

[Bayard Coolidge, N1HO via Elecraft]

I'm not familiar with VMWare, but under Parallels, youhave to make sure that 
the various devices, e.g., theserial lines and/or audio codecs, that you need 
for HRDhave been assigned to Parallels (and Windows) so thatWindows can legally 
access them. It sounds like you've gotthat much at least partially configured.
I'm assuming you have HRD 6.2.9.354 (which I have) or later.
Does the HRD Rig Control come up properly, and does itfollow your VFO when 
you turn the main knob on your K3?
On DM780, go into Program Options - Soundcard anddouble-check that it's 
looking at the audio device you thinkit should be looking at. (I use a 
SignaLink USB, so it showsup as USB Audio Codec; YMMV, and yes, I know 
better, but...).
Also under Program Options, you might want to investigateSoundcard 
Calibration. I'm not convinced that that alonewould fix your problem, but it 
might give you a better idea asto which tree to bark up next.
On the main DM780 window, click on Soundcard, which shouldbring up a couple 
of vertically oriented bar graphs - see ifthe receive one is behaving 
appropriately; you may need toadjust an input level on your Tascam or other 
device if it'sin Overload or barely bumping the thermometer. BTW, thereare 
some helpful tips in the info area in the lower right-handcorner of the 
Soundcard window.
You might also need to go into the OS X settings to double-checkthat it isn't 
(also) trying to grab the Tascam and/or the K3's serial line,even if VMWare and 
Windows think they own them.
I haven't looked at the HRD forum lately, but you might take a lookover there 
just in case someone with this particular configurationhas encountered this 
problem before.

Re: [Elecraft] New K3/K3S Beta Firmware, rev. 5.26: Support for K3S and upgraded modules

it did in the previous release as tested/released

There are no documented changes for the K3, therefore
you should not see any difference in the behavior of a

If you do not wish to test a beta deployment of an

Re: [Elecraft] 10 mHZ external reference VS the K3S's optionalKTCXO3-1

[Bayard Coolidge, N1HO via Elecraft]

We're talking about extreme precision here, but in somecases, it might be 
needed for MARS. I am not a member of MARS, soI am not privy to their current 
frequency tolerance requirements.But, at 1PPM, we're talking 10Hz at 10MHz.

I'm running a Trimble Thunderbolt GPSDO, and according to LadyHeather, I see a 
1 tau accuracy of 10 to the minus 13. Is thatextreme? Perhaps, for normal 
amateur use, but I think that it wouldprovide a decent "safety" margin for a 
MARS operator who needsto meet a certain frequency tolerance on a repeatable 
basis withno notice - i.e. instantly QSY to another frequency as needed, 
withoutworrying about how long it's been since the last formal calibration.

(And, to be even more inane, the correct abbreviation is "MHz." -capital M for 
Mega, capital H/lower case Z for Hertz, since it's aunit named for a person, 
and is therefore capitalized. Lower caseM is for milli, which in this case 
might describe how far off thedesired frequency a signal might be if it were 
sync'ed to an externalsource with the degree of accuracy under discussion 
here...)

Re: [Elecraft] Can not connect KIO3B USB with my MacMini

[Bayard Coolidge, N1HO via Elecraft]

Open up a terminal window and type:
ls -l /dev/tty.usb*
You should see something like this: (the serial number will differ)
crw-rw-rw-  1 root  wheel   19,   0 Feb 25 13:13 /dev/tty.usbserial-A567JW3P

If you're seeing that, then you should then be able tobring up the K3 Utility 
and "talk" to the K3. I just installedmy KIO3B about a month ago, and I'm 
running MacOS Sierra 10.12.3on a early 2015 13" Retina MacBook Pro. Under my 
"System Report",I see my USB disk (used for Time Machine) and the built-in 
BluetoothController plugged into the "USB 3.0 Bus", and then below that, Isee a 
"General Purpose USB Hub" as the next item plugged into the 3.0bus, and 
attached to the GP bus, I have a USB Audio CODEC and anFT232R USB UART.
The CODEC is a TI device and it's reporting that 500mA is availableto it, and 
it's requiring 0mA. The FTDI FT232R UART is likewisereporting 500mA available 
to it, and it's drawing 90mA. Since the"hub" is inside the KIO3B and being 
powered by it, it should notbe causing the USB power complaint you're getting 
on the Mini. BUT,since the Mini is an older device, it is probably USB2, not 
USB3,and can't source as much current, etc., and its circuitry *may* besomewhat 
intolerant of sudden changes. (I've had problems with blowingexternally powered 
USB2 hubs, apparently caused by hot un/plugging,resulting in MacOS reporting 
devices seen that Parallels and Windowswould/could not talk to. I've now 
switched to the KIO3B and I'm notgoing to do any hot un/plugging, just to be on 
the safe side.)
In fact, you might want to see if you can troubleshoot your problemby shutting 
everything down and powering it all down, configuring yourcabling, and then 
powering it all back up and booting it up. I knowit sounds like a nuisance, but 
it may give you a valuable indication.

 Subject: [Elecraft] Can not connect KIO3B USB with my MacMini
   
I am unable to connect the USB on my K3, modified with a KIO3B set of boards, 
to my MacMini, running OS10.9.5. I am not able to connect it to my MacbookPro 
running Sierra, 10.12.3, either. My Macs simply do not see the USB port. If I 
look at the “About This Mac” report on the Macs, I see that a “General Purpose 
USB Hub” is connected when the USB cable from the K3 to the Apple products is 
connected. I have made sure I have the latest drivers. I have tried different 
USB cables. I have Googled and can not find an explanation or a solution. I 
have done several system resets. Occasionally when I plug the USB cable into 
the Mini, but not the Pro, I get a message “USB Devices disabled - please 
disconnect the device drawing too much power” - doing that seems to do nothing. 
But I understand the KIO3B draws only 90ma and the Mini puts out 500ma.

Elecraft has told me that they have users who have Macs and KIO3B working.

Has anyone have a suggestion what I should do to fix this? The KIO3B boards 
were installed by Elecraft so I assume it left the factory working, although I 
have not ruled out a short or defect in the board that may have occurred
.

I have not tried the K3/board with a Windows computer but the same thing 
happens when I try to find the ports on Windows10 in Bootcamp.

Thanks in advance for any help.

Phil, W3HZZ

Re: [Elecraft] Multiple rig control and logging using a single Macbook Pro

[Bayard Coolidge, N1HO via Elecraft]

I'm running a mid-2015 MacBook Pro, but have just one K3 and one P3.However, I 
do have a powered USB hub to which I've attached an externalsound card (Asus 
Xonar U5) and three serial lines. The one cute thing aboutthose serial lines 
(which use the "real" FTDI FT232R devices) is that theyeach display a unique 
serial number, which can be viewed under the USBDevice Tree page under System 
Information which you dive into from the"About This Mac" GUI by going to 
"System Report". I've found that to bevery useful for troubleshooting, because 
I don't have to sort out device namesin "/dev", etc. (The 3 serial lines are 
for the K3, a Trimble ThunderboltGPSDO, and a Kantronics KPC3+, all of which 
run at different speeds).
I typically run WSJT-X under MacOS (Sierra, 10.12.1) using the K3's serial 
lineand the Xonar, but I can also run RUMlog and Fldigi. But, occasionally, 
I'll bootWindows 10 (under Parallels 12.1.1) to run HRD, Lady Heather, Winlink, 
Outpostand/or EZNEC+. I usually maintain the K3/P3 firmware using the usual 
utilitiesunder MacOS, but I can also do them under Windows if need be. Note 
that theP3 and the K3 utilities *do* allow you to select (under "Port") which 
serial lineyou wish to use. I don't know anything about MacloggerDX.
As I mentioned above, I am using an externally powered USB2 hub becauseI need 
to power the Xonar. I had a fair number of problems stabilizing 
thisconfiguration under Windows (7, then 10) because the GPSDO runs at 4800 
baudand Windows insisted it was a USB mouse. I alleviated it by rebooting 
Windows,sometimes 2 or 3 times in a row. Although the MacBook Pro is USB3 and 
the USB3spec stipulates that a USB3 port must supply more than enough current 
to supportthe U3 (I forget the exact numbers off the top of my head), it still 
didn't solve theproblem of multiple serial lines, coupled with the fact that 
the backup drive isattached directly to the (only) other USB port. One trick is 
to mark the cables carefullyand keep them in the same physical USB hub slots. 
Another is to avoid hot plugging,which despite manufacturers' propaganda WILL 
blow hubs; I keep a spare handy.
HTH, and 73 for a Happy Thanksgiving,

Re: [Elecraft] [K3S] WSJT-K 1.80rc 6m DATA A on LSB

[Bayard Coolidge, N1HO via Elecraft]

You may want to consider posting a message in the WSJT Yahoo! Groupbecause 
there have been a number of issues with WSJT-X 1.8-rc1 andthe Hamlib library 
which the development group has been plowing through.I was able to get a 
special build to test, which avoids the crash that I encounteredwhen first 
starting it on my K3, but I gather that they are seeing a lot of othersmall 
problems, so I suspect they'd like to swat your bug while they're at it.
I hadn't noticed that particular problem with my station, but I'll try to take 
a look for it,perhaps later this afternoon. That's not to say that perhaps 
there's a parameteron your rig (or a setting in your WSJT-X Configuration) that 
needs to be changed, however.

I'm running WSJT-X on FT8/JT65 just as of yesterday. Oddly, it seems to set
6M on DATA A in LSB. How might I fix that back to USB?

Re: [Elecraft] [K3S] WSJT-K 1.80rc 6m DATA A on LSB

To clarify my situation, I'm running a K3 with the new KIO3B with the integral 
sound and USB interface, and it was running properly using WJST-X V1.7. The 
Hamlib library problem that I encountered also affects certain Kenwood users as 
well, and the development team is well aware of the issues. I have used an 
external sound interface (Asus Xonar U5) in the past, but opted to simplify 
things when the KIO3B became available.

FWIW, I and many others have been using the posted compiled version of 
WSJT-X 1.8-rc1 from the official WSJT-X website with a K3, and without 
problems. I'm not using a lot of "bells and whistles" -- I'm using a 
vintage K3 with an outboard USB to serial converter from computer to 
rig, a Tascam US100 USB audio interface for the computer, and VOX with 
the K3 in DATA A mode. I'm doing almost no rig control -- all the USB to 
serial interface is doing is read and control frequency.  On the  
tab of   select the K3 under Rig, set the serial port that the 
computer has assigned to your USB to serial converter, set PTT method to 
VOX, set Mode to None, and set Split Operation to None.

The Tascam US100 is simply a very good vintage USB to analog stereo 
audio I/O designed for home semi-pro recording studios. There's lots of 
comparable stuff that works. It ONLY handles audio, no control functions.

Re: [Elecraft] Eclipse logistics and em-comm nets?

[Bayard Coolidge, N1HO via Elecraft]

>>> If you know of any specific networks that are planning to activate for this 
>>> event, please post that info here (and elsewhere).

I'm at my summer home in the mountains of western North Carolina, near 
Hendersonville,and we're expecting 99.9% totality at this QTH.
From the reports in the local news media, a huge influx of visitors is 
expected, which will basically saturatethe region, including (especially) the 
Great Smoky Mountains National Park (which spans parts of bothNC and TN), as 
well as the lower part of the Blue Ridge Parkway. Local EM officials are very 
concernedabout response times for emergency response units because the roads in 
that area are narrow (very fewof which are 4 lane), and very winding, with many 
switchbacks, blind corners, and steep drop-offs.
Buncombe County ARES (greater Asheville) has been enlisted to provide 
additional communications toaugment normal first response communications 
facilities.
Other counties have not, as yet, to my (admittedly limited) knowledge, formally 
called up local ARES groups.
I'm reasonably certain, based on personal experience with holiday traffic, that 
Interstate 40 in western NC,and Interstate 26 in western NC and upstate SC (and 
probably all the way down to Charleston) will bevery, very crowded/jammed. Both 
of them are mostly 4-lane, albeit with some hill-climbing lanes for trucks,but 
tend to get very crowded, even on "normal" weekends.
There are several 630m experimental stations in the immediate vicinity who are 
planning WSPRtransmissions throughout the event, and reception reports are 
always appreciated.
Luckily, it's a short walk (~1/4 mile) for my XYL and I to the local community 
park from which we can observe.

Re: [Elecraft] K3 Serial Comms with Apple Mac ?

[Bayard Coolidge, N1HO via Elecraft]

 I am not sure what you're planning to do with "Serial" but when I'm using my 
K3/KIO3B withWSJT-X, I have the program configured for CAT Control on 
/dev/cu.usbserial-A5x at aBaud rate of 38400, 8 data bits, 1 stop bit, 
Handshake set to 'None', and PTT Method of RTS(set to the same 
/dev/cu.usbserial device), Mode Data/Pkt, Split 'Rig', and a 1 second Poll 
Interval.CONFIG:KIO3B is set to 'nor'.
Permissions for the port device file are set to 666 and owner/group is 
root/wheel.
You might also want to double-check About My Mac -> System Report -> Hardware 
-> USBto see if the K3 is showing up - mine is a 'General Purpose USB Hub' with 
a TI vendor IDwhich has a USB Audio Codec (Burr-Brown) and an FT232R USB UART 
whose serial numbermatches the device special file that WSJT-X is talking to.
Also, go to System Preferences -> Network and make sure that that port is not 
configured.(It most likely is not, but Murphy does very strange things at 
times!)
It wouldn't surprise me if Serial might have a permission problem/setting 
that's fouling you up,but that's just a SWAG on my part. I'm running Lady 
Heather through another USB line to myGPSDO without any fiddling on the macOS 
side, but you never know.

The main web site's position reporting may be outdated because, I think,that 
they're relaying their position via satellite (Iridium, perhaps?) whichcan get 
pretty expensive. Given the length of the journey, it's probablynot worthwhile 
providing hour-by-hour position updates. They'll get therewhen they get there, 
and they'll get on the air after they get things set up.

Re: [Elecraft] FT8 on PX3? Logging FT8 contacts on a Mac?

[Bayard Coolidge, N1HO via Elecraft]

The macOS version of WSJT-X logs contacts in the same way as the Windows and 
Linux versions.
I assume the version of macOS you are running is reasonably up to date, 
preferably Sierra orHigh Sierra, and that you installed WSJT-X as a user.
If you are having problems logging, check WSJT-X ->  Preferences to make sure 
you have things setup the way you want/need.
If you want to review recent QSOs, then you can go to WSTJX -> File -> Open log 
directorywhich will bring up a Finder window for the directory where all of the 
log files reside, which istypically /Users/yourusername/Library/Application 
Support/WSJT-X. Simply click on "wsjtx.log" andit will bring up the log file 
for you to inspect/search.
If you are looking to automatically log your WSJT-X QSOs directly into your 
logging program, youshould consult your logging program's documentation. I use 
RUMlog, published by Tom, DL2RUM,and there are a couple of settings within it 
that allow the two programs to communicate via UDPpackets within your system, 
and the integration is wonderful - I leave RUMlog running in the background,and 
operate primarily in the main WSJT-X window (while watching the waterfall on 
its window, primarilyto pick a clear transmit frequency), and when I actually 
make a QSO, and WSJT-X prompts me tolog it (because I have set my WSJT-X 
Preferences to do so), and I click on the "Log It" box, it sendsthe information 
to RUMlog, which then logs it as if I'd entered it myself. The only thing I 
have to dofrom there, manually, on RUMlog is to ship the QSO up to LoTW if I so 
choose.
Support for WSJT-X is available on the Yahoo! Group as documented in the Help 
files, and theyare very responsive.
Apologies if the formatting of my message looks weird on the mailing list - 
it's a Yahoo! problem,which tends to mangle line endings and paragraphing.

Re: [Elecraft] Mac Clock Question

[Bayard Coolidge, N1HO via Elecraft]

 I run my iMac 24x7, and do have it configured to use the ntp.org pool servers, 
and it appearsto do the trick for the various WSJT-X modes that I use on HF. 
However, even when I doreboot occasionally, any transient loss of sync to the 
NTP servers doesn't seriously affectme when I use WSJT-X. OTOH, since I spend a 
lot more time listening than transmitting,while searching for "new ones", NTP 
has plenty of time to sync back up :-)
I suppose if you want to really go overboard, you could get yourself a GPSDO 
and theninstall gpsd (GPSd — Put your GPS on the net!) and NTPsec (Welcome to 
NTPsec)and then you'd not only be good-to-go for the WSJT-X modes, but you 
could then serveup a reference for the rest of us. Both of those can, AFAICT, 
be built for Windows,Linux and macOS, assuming you have the software 
development tools (compiler,linker, libraries, etc.) installed.
BTW, NTPsec is a new/rewritten implementation of NTP that is far more secure 
and robust,and does not need gpsd or a GPSDO to use. If you're concerned that 
your currentOS/computing environment might not be behaving as well as you'd 
like with respect to NTP,it might be worthwhile to take a look at NTPsec.

(105Ah)AGM SLA battery charged, and that feeds a RigRunner. I adjusted the 
RS-35A to14.1 V on the RigRunner (on receive), and it dips to 13.5 or so on 
transmitwhen running the K3 at 100W out.
As others have mentioned, it is a case of using large wire - #10 or #8 - in the 
shortestlengths possible, and the heavier-rated APPs throughout.
There are numerous articles out on the web and in the archives of this mailing 
list aboutamendments to Astron power supplies and depending on the age of 
yours, you may needto investigate what the root cause of the buzzing is, be it 
simply loose fastening hardwareor perhaps a filter capacitor that's well past 
its prime.

Re: [Elecraft] Mobile high power

[Bayard Coolidge, N1HO via Elecraft]

 There are implications for fixed-location operators as well. I can only run 
about 175W into my (very) shortinverted-L on 630m - above that, I trip the car 
alarm on my upscale European-made SUV parked in the driveway.I'm in a fairly 
crowded neighborhood - house lots are on the order of 1/5th of an acre - with a 
condo complexnext door to me, which generates a lot of slow speed traffic, so 
it's quite likely that an RF-susceptible vehiclecould have an interesting 
experience if I should happen to key up on JT9 while it's rolling by the 
house.(My EIRP is about 1.25W, 6dB below the legal limit).

Re: [Elecraft] WSJT-X using KX3 + MacBook Air

[Bayard Coolidge, N1HO via Elecraft]

 Can you fill us in on exactly what versions of macOS and WSJT-X youare trying 
to use?
Also, did you pay attention to the release notes for WSJT-X and use the correct 
values in /etc/sysctl.conf?(I was bitten - badly - by that myself!). I'm still 
on Mojave (10.14.6), so if you're on Catalina, YMMV.
Go into (black Apple icon) -> About This Mac -> System Report -> USBand make 
sure that it sees/enumerates the General Purpose USB Hub, the USB Audio 
CODEC,and the FT232R USB UART that are connected to your KX3. I'm using a K3 
withthe updated KIO3B, etc. so I don't specifically know if the KX3 is 
configured in exactlythe same manner, but I would think that it would be 
somewhat similar overall; I donot need any other connections, such as the mic 
input jacks. Also, make sure tonote what the serial number of the FT232R is, as 
there is a device special file,e.g. /dev/tty.usbserial-A1234567, that is 
created for that particular device, and thatis what you should be specifying to 
WSJT-X->Preferences->Radio for your rig controls.The WSJT-X->Preferences->Audio 
should, of course, be set to "USB CODEC" BUTWSJT-X may/should initially ask to 
allow connection to the mic input and you shouldanswer "YES". (Yeah, that was 
kind of counter-intuitive to me, too...)
There had been a lot of discussion about this in the WSJT-X Yahoo! Group but 
they just (finally)shifted over to a Groups.io group and I suspect/fear that 
much of this sort of informationhas been (temporarily?) lost.

Also, IC7300 requires only cable for rig control and audio tx/rx. Is that

Re: [Elecraft] K4 Power Supply Recommendation

[Bayard Coolidge, N1HO via Elecraft]

 The power system for my K3/P3 consists of a large SLA AGM battery that is 
float-charged froma West Mountain Radio PGS-40 and an Astron RS-25, which I 
adjusted to 14.2V to accommodatethe drop through the wiring, the PGS-40 and the 
RigRunner. This has kept things very quiet for me,and also keeps me on the air 
through any AC power interruptions, and I use it at both my primaryQTH in south 
Florida as well as my summer residence in western NC. This should fit your

Subject: [Elecraft] K4 Power Supply Recommendation

Hello everyone!

Like most here I am waiting for my K4.  Currently I am running the Power Werx 
SS30DV from the Elecraft site for my KX3 and Kxpa100.  I was planning on buying 
another for the K4 but thought I would ask opinions first.  I am assembling my 
first real HF station and going the cry once route.  I would rather pay a bit 
more up front and get something solid rather than saving a few bucks now only 
to upgrade later.  

Given what I intend to spend on the K4, I don’t want to skimp on its PS if 
spending a bit more will improve performance.  My budget is let’s say $500 and 
my question is would buying a bigger switching or linear PS for the K4 make 
sense?  My KX3 PS has caused me no issues and if that is the way to go I am 
groovy.  


Thanks!

Re: [Elecraft] Mac vs K3s - Again

[Bayard Coolidge, N1HO via Elecraft]

 Given that you are running generally older hardware and system software, you 
probably don'tneed to worry about how "out of date" your FTDI driver might be. 
(I'm running a 2017 iMac withBig Sur installed and working beautifully). I 
assume that your USB hardware really is FTDI andnot one of the infamous clones 
that have been discussed to death here and in other forums.If it really is 
FTDI, then D2XX Drivers - FTDI lists version 1.4.22 as having been released 
on21 January 2021 (!) and is suitable for Mac OS X 10.4 Tiger or later, which 
should be OK for you.

Re: [Elecraft] K-Line / ZeroFive Antennas

[Bayard Coolidge, N1HO via Elecraft]

 Hi, Jim -
I don't have a KAT500, but I do have an upgraded K3 (near-K3s) with the 
internal tuner that I run barefoot to a ZeroFive 30m quarter-wave vertical with 
a wire attached to its tip, running about 40 feet to the north to the top of an 
avocado tree. My radial field is putrid - just a couple of quarter-wave wires 
for each band, because our house lot in south Florida is 1/5 acre, and I have 
7.5 kV 3-phase power lines running down two sides of the property. However, it 
(and its predecessor, a Zero-Five 20m quarter-wave vertical) has held up very 
well in the salt air, and performed beautifully. In fact, I also have a large 
coil that allows me to tune it on 630m. When using it without the 630m coil, 
the internal tuner matches up beautifully on all bands from 80m through 10m. 
I've always been very impressed by the construction of these antennas - 
beautiful machine work, precise fittings, and very durable, so I highly 
recommend them from that perspective.
I augmented my radial field with three 8 foot ground rods pounded into the sand 
angled downward away from the base, plus I ran some #000to the ground screen 
under the swimming pool. Typical ground resistance at resonance is about 25 
Ohms.
I'm not subject to HOA/CC restrictions, and our city does allow amateur radio 
antennas to a certain extent (60 ft max for the first tower, oneadditional 
tower at 40ft), but considering we're right on the Atlantic coast, that's 
pretty understandable.
(And, Florida Power & Light is in the process of moving all of the HV and 
household feeders underground, so really, at this writing, I have 3-phaseHV 
lines along only one side of the property, and those might have been 
de-energized at this point as well; I will perform another round ofnoise 
measurements when we return in November, but the noise was about S9 this winter 
before they started working on the lines).

Did you have the KAT500 on your desk, or remote at the antenna base? These

that seems to indicate that these very expensive verticals might be a viable

Re: [Elecraft] K3 Utility vs macOS Monterey?

[Bayard Coolidge, N1HO via Elecraft]

 Does the USB port show up when you go to 'About This Mac' and then to 'System 
Report' and then to 'Hardware:USB' ?
Assuming you are using a quality USB cable (from either Elecraft or Sabrent) 
that uses the FTDI chip set, and not someother cable that uses a Prolific chip 
set. (I have several USB devices on my Mac, and I keep careful track of which 
iswhich by tracking their serial numbers as denoted by the /dev filenames in 
addition to what 'About This Mac' displays,as I've run into problems in the 
past, particularly when using Windows under Parallels, given how picky Windows 
isabout device ports and ordering).
Does the port show up under another program, such as WSJT-X or JTDX? Were 
either of those programs (or othersthat may be trying to use the particular USB 
port) still running when you invoked the K3 Utility? I don't control my K3using 
RUMlog (which I do use for logging), but it does have some rig control 
capabilities, for example. I'm not familiarwith the other Mac logging programs 
out there, so I can't comment on what effect they might have in your situation.

Re: [Elecraft] Mac Logging Software

[Bayard Coolidge, N1HO via Elecraft]

 I've been using RUMlogNG for years, and it's worked beautifully for me, and 
it's well-maintained. It integrateswith LoTW beautifully, as well as other 
databases. There are numerous rig control features available that Idon't 
personally use, since I tend to use WSJT-X or JTDX, and it does cooperate with 
those two programs sothat when you finish a QSO, the data is sent from them to 
RUMlogNG and is plopped into my log automatically.For example, it will track 
the frequency data from a K3 or K4D, and some ops use it to directly key it on 
CW.For manual (i.e., non-digital) modes, QSO entry is simple, straightforward 
and intuitive.

It's available directly from the AppStore or you can go to DL2RUM's website 
directly, and is free.

I also use it for contest logging - there is a pull-down menu that sets up a 
separate logging interface configuredfor the specific contest you're working, 
to present real-time scores, missing multipliers, etc.

The formatting of this e-mail may've been messed up by Yahoo, and should not 
reflect on the value of RUMlogNG :-)

Re: [Elecraft] [K3] K3 MacOS M1 Mini

[Bayard Coolidge, N1HO via Elecraft]

 About a month ago, I upgraded from an old (2015?) Intel i5-based MBP to the 
new M2 MBP, and was able to migrate everything over to it seamlessly by having 
the M2 import all of my bits from the TimeMachine backup. I've been using 
RUMlogNG for years, and it works nicely with both WSJT-X and JTDX 
*simultaneously*, with WSJT-X driving the upgraded K3 (near-K3s) operating with 
the KXV3B on 630m and JTDX operating the K4D on the HF bands. I do not have 
RUMlogNG do any rig control for me, however.
I have 24MB of memory in this MBP, but I was operating with 16MB on the old MBP 
just fine. I had a 250GB SSD on the old MBP, but splurged for 1TB on the M2. 
However, I think you should be able to get by with 16/250 on an Apple Silicon 
based machine unless you're planning to watch a movie or edit video while 
you're working the bands :-) One trick that I pull is to have a separate 
partition on a large USB drive (which is primarily used for TimeMachine) to 
keep less-needed files, as well as the log files generated by WSJT-X and JTDX. 
I simply created a symbolic link in the files for those two apps to point to 
the right places on the USB drive.
Only fly in the ointment I've encountered is that I run Parallels and it 
upgraded to the latest version and then installed Windows 11 ARM for me. I 
haven't played with it yet, so I don't know how much it will bog down the 
system. *BUT*, be forewarned that Ham Radio DeLuxe is Intel-only and flatly 
told me in their support forum that they do NOT intend to make an ARM64 version 
for Windows 11. I only use HRD as a backup log program to review my awards 
standing (e.g., DXCC, WPX, etc.), and now do so on my Intel-based iMac, but I 
plan to retire it eventually. I've never used it for rig control, etc.
I also had a minor problem porting 'flaa' to the new system, and had to forage 
for an as-yet unreleased version and compile it myself. But, once I did, it 
worked beautifully. Also, I was able to use the latest versions of 
nanovna-saverwith my nanoVNA-F, by doing a 'chmod +x' one time to make it 
executable, but I do have to invoke it from a command line in Terminal, and it 
takes a while to start up, even though I have the latest Python version 
installed.
I have not updated to Ventura yet, either - simply too busy doing other/fun 
stuff - but I'll be happy to assist as best I can.

I have K4 radios at a mountain QTH and a valley QTH and either one can
connect to and use the other.

Re: [Elecraft] Mysterious K3 Symptoms - RFI?

[Bayard Coolidge, N1HO via Elecraft]

 Although I don't have an amp, and ran my K3 barefoot, and run my K4D barefoot 
as well, I do have a 100 foot CAT5E cable running into the shack from the other 
end of the house, through the attic (there being no basement here in south 
Florida!). Initially, I was seeing a fair amount of noise from it, and was able 
to quench it by winding a couple of turns around a small clamp-on choke.
That doesn't seem to affect the network performance, so I can reliably run it 
at 400MBit/second, and it seems to clean up whatever other noise it's picking 
up from nearby homes (most are on small lots of about 1/5 acre) and the 
condominium complex next door. I still have some strange noise from other 
sources coming in from the antenna, and the HVAC's air handler is very noisy, 
particularly on 30m through 15m, but I know it's not the twisted-pair Ethernet 
line. My CAT5E cable plugs into a small AC-powered router, and feeds my Mac, 
the K4D, as well as a laptop occasionally.
HTH, and 73,

One culprit I can think of is a 100-foot Ethernet cable between my 
station and my FIOS router.  I have bought a shielded replacement but 
have not yet installed it.  After reading some of the recent commentary 
about so-called "shielded" cables, I'm wondering if this is worth doing.

Any suggestions, either K-3-specific or more general, would be much 
appreciated.

Re: [Elecraft] Mysterious K3 Symptoms - RFI?

[Bayard Coolidge, N1HO via Elecraft]

 Unfortunately, with the high population density in my immediate neighborhood, 
especially with 150+ condominium apartments right next door, I have a difficult 
time getting a reliable wi-fi connection to my home network. I'm about 900 feet 
(240m) west of the Intracoastal Waterway, and have 2, 3, 5 and 7 floor condo 
buildings between me and the ICW. To the north, west and south, I have 
single-family homes. Along the south (i.e., rear) side of our house lot, I have 
7.5kV 3-phase power lines overhead, which feed the homes on the block south of 
us; we're fed by underground feeders installed 2 years ago. To make matters 
more interesting, we have a steel "ridgepole" running the length of the house, 
atop the actual conventional wooden ridgepole, which supports the curved 
concrete tiles at the top of the roof. I suspect that noise is coupling from it 
onto my TWP Ethernet line as well. I used the simple/cheap MFJ clamp-on chokes 
at both the shack end and the end in the den where it's plugged into the ISP's 
modem/router. Basically, I'm doing the best I can with what I've got.
73,
Brandy, N1HO (EL96xh)

 I recommend replacing Ethernet cables with wifi when possible, both for noise 
and rfi problems, as well as reducing the chance of lightning damage.
