[Elecraft] Elecraft CW Net Report
Good Evening, The sun popped out for a few minutes after a misty, wet day. This weather is perfect for growing ferns. Some of them are now over ten feet tall. They are filling any hollows in the terrain. Occasionally you will see one get pulled down out of the canopy. This is about the only way you ever "see" a mountain beaver. They live under the ferns creating large mounds of dirt from the holes you need to avoid. The elk and deer eat the ferns and use them for bedding. They do keep the forest floor damp, cool, and shaded. Perfect for many species of fungi. Fallen limbs are quickly recycled back to nutrients to feed the forest. Forty meters had more noise with deeper QSB than did twenty meters. During the second net the noise level increased in steps. By the end it was hard to hear my own sending. Twenty meters had less noise while propagation was a little better. I did miss a faint "V" at the end of a call. QSB was not timed effectively.

Later I was working on some code while listening to a TV show. Then a character mentioned setting up their laptop with Kali Linux. I had never heard of this so I stopped working and looked it up. Seems Kali Linux is used by white hat hackers to test the security of networks. I downloaded a copy of a virtual machine and imported it into my Virtual Box installation. This version of Linux has a large number of tools all related to penetration testing and prevention. I am learning more about my heterogeneous home network than I ever imagined. With these tools you could test the K4 for any network vulnerabilities.

Re: [Elecraft] HW-16
I actually had an HW16 for a little while around 1993. I bought it at a hamfest, complete with the HG10 VFO, and the crystal and what not to reverse the mod that moved it from 15 meters to 20 meters if I so chose. I did not so choose. It was a fun rig, and I had no trouble with it, even tuning eyes-free. Even used it when I was temporarily in a different state as my primary station for a little while.

Re: [Elecraft] HW-16
The HW-16 was a great rig back then, with silent QSK and a good crystal filter. I remember getting frustrated one night, and I cranked the PWR knob past the red mark on the plate-current meter that showed the 75-watt Novice DC input plate current limit. I had just turned 17, and worked 50 hrs at $2/hr to buy that kit. I was going to get a QSO that night even though I knew the FCC would soon be battering down my door and dragging me away in handcuffs.

[Elecraft] Subject: Using the Antenna Tuner in the XPA100
Mike, I lived in New England for about 15 years and know I'm not the first to talk to you in direct terms. Used to sail in Marblehead and know just how snotty people there can be. If you don't find my very useful and concise advice to be "constructive" that's your problem. I'm 80 and find the judgements of others less and less interesting, especially when I'm trying to help them. It's great you have antenna tuner experience, although it's pretty irrelevant to your question. The fact that you would suggest plugging the end of a wire into an automatic tuner AT ALL shows a fundamental misunderstanding of both the wire and the tuner. The autotune, has a two conductor output and you really have to use both of them! I suggested some reading topics that would help you understand what you asked about, because it's unlikely anyone here will have time to start from scratch and explain the subject to you. You say your self that the tuner is built for unbalanced coax, so why ask about end fed wires? Sure, you'll always get "replies." How much did they help? You'll mote that al the BALUN/UNUN talk involves USING A COAX, TWO CONDUCTOR line on the output of the tuner, NOT plgging a wire into it! Sounds a lot like what I was trying to tell you! Sure, you sometimes get away without an earth ground. That's because the shield of whatever feedline you hook up forms enough counterpoise to handle the current coming back to the chassis of the tuner. Don't lecture me about ham spirit. I've likely helped as many hams as you, with GOOD advice. I've also been told, in no uncertain terms, that my question really showed that I had reading to do. Yes, I meant to be a little short but I did not mean to be offensive. If you can't deal with the answer, simply ignore it. If you think people talking to you about long runs of coax and various coupling means answers your question about end fed wire in your tuner, there's nothing I can do. Did you actually think about any of the issues I raised? My time is very short, because of care I have to give to others, and you are lucky to receive any of it, since I have my own problems to solve. This note constitutes the LAST of it that you will receive and I promise the esteemed members of the list that I'm off the subject. If you want to destroy a valuable piece of equipment, go for it!

Re: [Elecraft] HW-16
Its long-term utility was limited by the one-year non-renewable Novice license of that era. It actually was a pretty good CW rig. I used it long after I upgraded from Novice. W1AW used one for their Novice station for awhile. It had true full break-in that worked perfectly. The receiver came standard with a 500 Hz crystal filter. With the external HG-10 VFO you had separate stable transmit and receive VFOs so working split was not a problem. Alan N1AL On 7/3/22 14:54, Mike Morrow wrote: I don't know what an HW-16 is.

Re: [Elecraft] COM port problems
I have not had the problem of devices “moving” on the Mac. I think the Mac uses the FDTI serial number to keep them straight. When I was using a RS-232 protocol analyzer on to chase a problem, I had 4 Elecraft FTDI RS-232 <—> USB cables hooked up. Two for the two directions of the analyzer, one for the K3 acting as test machine, and 1 for a KX3 acting as the other end of the RF link. The Mac always seemed to keep them straight, even when I plugged them into different USB sockets on hubs etc. I’ve always wondered why Microsoft hasn’t fixed this problem. And I sympathize with my friends who use Windows. 73 Bill AE6JV > On Jul 3, 2022, at 06:59:59, Dave B via Elecraft > wrote: > > I have zero experience of Apple Mac's.

Re: [Elecraft] K4D Receiver Question
As with most modern radios, the RF gain control is actually an IF gain control that scales the signal level mathematically at the input to the DSP. It's often used by operators who like to manually control the level of signal ahead of the DSP AGC. This is different from "hard" front-end gain adjustment, which in the K4 is handled four ways: - preamp settings - attenuator settings - *automatic* gain reduction via preamp/attenuator settings (if enabled in the menu) - carrier operated relay (COR) You have control over preamp/attenuator settings, and you can enable or disable automatic gain reduction. But the COR is handled independently. It kicks in automatically whenever the signal into the antenna jack exceeds something like +25 dBm. 73, Wayne N6KR > On Jul 3, 2022, at 7:19 AM, Roy Morris, Jr. via Elecraft > wrote: > > Considering the high noise level on the 75 meter band, has anyone had to use > both 21 db of attenuation with PRE/ATTN button and additional attenuation > with the RF/SQL encoder?

[Elecraft] FW: K3 Synthesizer, KSYN3A
Hello K3 user group: I have a K3 with the original synthesizer boards. I am looking for a pair of the new KSYN3A boards. I have spoken to Elecraft tech support and I am on their list in case they decide (Wayne, you might comment) to make a run of new synthesizer boards. The Tech Rep I spoke to didn’t know if a new run was going to happen anytime soon. So as a long shot I thought I would see if by chance any of you might have a pair that I might acquire.

FYI...
Windows users, can use these utilities to find out what is/was connected to
their PC's by USB etc...
USBview: A Microsoft (was System Internals who MS bought) tool.
The easiest way to find it is here:- https://ftdichip.com/utilities/ "Microsoft
USBView - USB Connection Viewer"
There is a link to download a zipfile that contains it:-
https://ftdichip.com/wp-content/uploads/2020/07/usbview.zip
That contains a single stand-alone exe file that is the utility. Put it in a
folder of it's own, and create a shortcut to it for your desktop.
(Also a link to a Linux version, that does work, but needs compiling from
source, and running using sudo as it needs elevated rights to read the running
configuration files to get the information to display.)
Another similar tool is USBDview
https://www.nirsoft.net/utils/usb_devices_view.html
That shows a much more detailed list of what Windows knows about, that is, any
USB device that was ever connected since windows was initially installed,
regardless of if it was ever used!
You can also delete instances of old / defunct devices easily with this very
useful tool.
(Some AV tools say it's suspect or malicious. Use VirusTotal.com to verify if
it (or anything else) is bad, on a file by file, or webpage basis. )
Note that if for whatever reason Windows (or Linux) re-enumerates things, the
linkage between a physical device and it's COM port number can (and often
does!) change. Seemingly at the will of some minor deity somewhere... That
of course, will break any software that expects some specific device to be at a
specific COM port.
Windows has the means to "Fix" that. (Known to work up to Win10, that I have
personally tested it on.) Find those details here:-
https://sourceforge.net/p/fldigi/wiki/windows_com_howto/
I wrote much of that after hours of "fun" some years ago... As above, it
works well with Win-10.
For Linux users, look up and explore the world of "udev rules". But...
They are only really easy to setup, if a USB device has a unique "something" in
it's USB descriptor, that the OS uses to identify it. Such as a Serial Number.
FTDI devices have unique sn's, but Prolific, SiLabs and others sadly do not.
So, it gets funky if you have several of the same type of device that all "look
the same" to the OS.
(Newer genuine FTDI devices also have the ability to have that serial number
(and some other settings) re-programmed! Fakes seem to take the
reprogramming, but the new data does not "stick". Don't ask how I found that
out!)
However, you can use the "connection path" between the OS and the Device, as a
deciding factor, but then you are forced into hooking everything up "EXACTLY"
the same each time. (Hub's and all...) But it does work.
Using them, you create "symbolic links" to the actual port used, so for example
my VHF radio appears as /dev/ttyFT736 Regardless of which hole I connect it's
associated FTDI serial adapter to on the PC (or via any
hubs!) Or what /dev/ttyUSB* the OS re-assigns it to if things are
re-enumerated for whatever reason.)
For example, this is the rule for my ancient FT-736
#FT-736r
SUBSYSTEM=="tty", ATTRS{serial}=="A50285BI", SYMLINK+="ttyFT736"
Flrig and most other software both accept symlinks and work well.
(For the odd software title that insists on using the full /dev/ttyUSBx for
example, they often store their settings in a file that can often be edited
with a text editor, where you can in effect force-feed it the symlink. The
fun part is finding where that is stored!)
The exact details of how to use udev rules are way to much for this list, but
as usual, there are many websites that can furnish such info, plus some
examples. Has to be said though, different "flavors" of Linux, often store
such rules in subtly different places to others.
I have zero experience of Apple Mac's. But they use a custom version of BSD as
their OS, that is more like Unix than Linux. So it is likely some if not all
of the above could work on them too. If Apple let you dig that deep and
meddle...
Hope some of the above helps, and or gives people some ideas how to tame things.

Re: [Elecraft] KPA1500/PS SPACING
My boyhood neighbor and "Elmer", Lee, W7UVR (see my QRZ page) fell into a trust fund income and had all of the toys. He enlisted a local ham, who was a tool and die maker and great builder of equipment, to build the mechanicals of a CW rig using a Geloso VFO driving an HK57. I begged him to let me buy and finish the rig. He said, no doubt correctly at the time, that this would be beyond me, but his brother, W6GMC, had a DX100 that he built but no longer wanted, and that would be the ideal rig for me. IIRC the kit sold for $189 and he would sell the assembled rig for the same amount and I could pay him $5/week. The deal was struck and he drove to CA to pick up the DX100. That and my BC-342-N was the station. When I got interested in two-meters in the 1960s I did build quite a few amps; one of them used an 829B and I "stole" the modulated B+ from the DX100 to run it on AM.

"Microsoft USBView - USB Connection Viewer"
There is a link to download a zipfile that contains it:-
https://ftdichip.com/wp-content/uploads/2020/07/usbview.zip
That contains a single stand-alone exe file that is the utility. Put it
in a folder of it's own, and create a shortcut to it for your desktop.
(Also a link to a Linux version, that does work, but needs compiling
from source, and running using sudo as it needs elevated rights to read
the running configuration files to get the information to display.)
Another similar tool is USBDview
https://www.nirsoft.net/utils/usb_devices_view.html
That shows a much more detailed list of what Windows knows about, that
is, any USB device that was ever connected since windows was initially
installed, regardless of if it was ever used!
You can also delete instances of old / defunct devices easily with this
very useful tool.
(Some AV tools say it's suspect or malicious. Use VirusTotal.com to
verify if it (or anything else) is bad, on a file by file, or webpage
basis. )
Note that if for whatever reason Windows (or Linux) re-enumerates
things, the linkage between a physical device and it's COM port number
can (and often does!) change. Seemingly at the will of some minor deity
somewhere... That of course, will break any software that expects some
specific device to be at a specific COM port.
Windows has the means to "Fix" that. (Known to work up to Win10, that I
have personally tested it on.)
Find those details here:-
https://sourceforge.net/p/fldigi/wiki/windows_com_howto/
I wrote much of that after hours of "fun" some years ago... As above,
it works well with Win-10.
For Linux users, look up and explore the world of "udev rules". But...
They are only really easy to setup, if a USB device has a unique
"something" in it's USB descriptor, that the OS uses to identify it.
Such as a Serial Number. FTDI devices have unique sn's, but Prolific,
SiLabs and others sadly do not. So, it gets funky if you have several
of the same type of device that all "look the same" to the OS.
(Newer genuine FTDI devices also have the ability to have that serial
number (and some other settings) re-programmed! Fakes seem to take the
reprogramming, but the new data does not "stick". Don't ask how I found
that out!)
However, you can use the "connection path" between the OS and the
Device, as a deciding factor, but then you are forced into hooking
everything up "EXACTLY" the same each time. (Hub's and all...) But it
does work.
Using them, you create "symbolic links" to the actual port used, so for
example my VHF radio appears as /dev/ttyFT736 Regardless of which hole
I connect it's associated FTDI serial adapter to on the PC (or via any
hubs!) Or what /dev/ttyUSB* the OS re-assigns it to if things are
re-enumerated for whatever reason.)
For example, this is the rule for my ancient FT-736
#FT-736r
SUBSYSTEM=="tty", ATTRS{serial}=="A50285BI", SYMLINK+="ttyFT736"
Flrig and most other software both accept symlinks and work well.
(For the odd software title that insists on using the full /dev/ttyUSBx
for example, they often store their settings in a file that can often be
edited with a text editor, where you can in effect force-feed it the
symlink. The fun part is finding where that is stored!)
The exact details of how to use udev rules are way to much for this
list, but as usual, there are many websites that can furnish such info,
plus some examples. Has to be said though, different "flavors" of
Linux, often store such rules in subtly different places to others.
I have zero experience of Apple Mac's. But they use a custom version of
BSD as their OS, that is more like Unix than Linux. So it is likely
some if not all of the above could work on them too. If Apple let you
dig that deep and meddle...
Hope some of the above helps, and or gives people some ideas how to tame
things.

Re: [Elecraft] KPA1500/PS SPACING
Thanks for the responses. The KPA1500 manual says just 1" on the sides of the RF deck and PS is adequate, so I think I'll be OK--as will my HW-16. 73 Eric WD6DBM On Sat, Jul 2, 2022, 6:01 PM jerry wrote: > On 2022-07-02 15:35, Jim Brown wrote: > > > > I bought my first amp in 2004. > > *** And I built my first amp in 1971.
