Re: [Elecraft] Data protection and recovery techniques

[Bill Frantz]

Being a Mac guy, I use "Time Machine". I do test it every once 
in a while when I recover a file, but having been in the 
computer industry for my career, I am generally careful enough 
that I don't have to recover files. (Knock on wood.)


I have the largest disk I could find at Costco as a backup disk 
sitting on my desk.


The real test comes when I buy an new computer and restore the 
entire backup to the new machine. That has worked through 
several new computers. The one time it didn't work, the old 
backup was so many no-longer-supported levels back, that the new 
machine didn't recognize it. However, with Time Machine, if you 
open the backup folder on the backup disk, you can dig down to a 
complete file system image that can just be copied. I like 
backup systems that are simple and don't try to do irreversible magic.


The other dimension of backup is several offsite disks. One is 
at a house nearby, and another is on the other coast. Whenever I 
travel to those locations, I make a backup. If everthing here 
goes up in smoke, I do have some recourse.

[Elecraft] Elecraft CW Net Announcement

[kevinr]

Good Evening,

   The sun just came out.  For the first time this week.  It was 
pouring only minutes ago.  What a gloomy spring.  In other news, there 
was a CME today.  Unfortunately it was from the other side of the sun.  
It could mean an active sunspot region could pass over the limb in a 
week or so.  One can never tell, the sunspots have been evaporating 
quickly lately.  This could change too.


Please join us on (or near):

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
  7047 kHz at z Monday (5 PM PDT Sunday)

   73,
  Kevin. KD5ONS

Yes.  Each morning I check to see if the backup ran overnight and if the
file size is appropriate for what it should be.  If it's Zero I start
looking why.

Re: [Elecraft] CW rise time setting

[E.H. Russell]

In computer space 4ms is an eternity. I do wonder what is going on there. And 
also hope the K4 fixes it. Thanks again for the scope shot.

The plot in the QST review of the K3S shows the delay between "key closure" 
(the KEY jack of K3S) and RF out.  My plot shows the delay between "amp relay 
closure" (the KEY OUT jack of K3S) and RF, which is more critical.

 

Most folks assume there will be no delay between KEY closure and KEY OUT 
closure, but there is an extra delay (of about 5 ms, minimum) in the K3S.  The 
same applies to PTT IN closure and KEY OUT closure; that is, there is an 
unexplained fixed 5 ms delay in the K3S, probably due to slow firmware logic 
testing for TX Inhibit or an intentional enforcement of some minimum delay in 
RF output.

 

Most radios close KEY OUT immediately upon key closure of either the KEY jack 
or the PTT IN jack.  The K3 does not; it "hesitates" before closing KEY OUT.

 

I'm also hoping the K4 will eliminate this unusual behavior.

Thanks for the scope shot and info. I compared the waveform to the QST K3S 
review, which seems to show a little over 10ms before RF appears. Is this 
because they used different settings?

 

Will be interesting to see how the new radio CW looks in time and frequency 
domains. Also how the turnaround latency is managed.

Anything published out there?

 

Ed,

 

Per your request, I am publishing this scope screen capture which plots the CW 
rise time in my K3 with the KSYN3A synthesizer upgrade.  It's about 4 ms from 0 
RF to full RF (2 ms per horizontal division):

 

https://www.kkn.net/~n6tv/N6TV_K3_Ser_1494_FW_05.64_TX_DLY_8_CW_QRQ_OFF.png

 

The vertical markers are there to illustrate that CONFIG:TX DLY nor 008  
provides only about 6 ms of RF delay after "KEY OUT" goes to ground, not 8 ms, 
and there is jitter in that delay as well (not shown).  If CW QRQ mode is 
enabled, the delay drops to about 4.6 ms and the TX DLY setting is completely 
ignored.

 

This was discussed here two years ago.  See this post for suggestions on how to 
avoid hot-switching a non-Elecraft amplifier driven by a K3 or K3S:

Re: [Elecraft] Data protection and recovery techniques

And, do any of you ever check the backups to make sure they really have 
anything there?  In the olden days of reel-to-reel tapes, the number of 
backup tapes in the library that were actually blank often exceeded the 
number of valid tapes in the library.  Lots of scrambling when you 
needed that tape.

Re: [Elecraft] Computer Monitor Recommendations

[John K9UWA]

THANK YOU K9YC Jim

I have read all the monitor solutions offered since the OP posted his question 
yesterday. 
#1 I never met a monitor yet that didn't emit RFI and at least 90% of the noise 
was 
from the no surprise here Switching Power Supply. That said I purchase two LG  
LCD monitors 2 years ago that have EXTERNAL WALL WART supplies. No I 
didn't want to go inside a brand new monitor to try curing the SMPS noise. I 
can 
replace a Wall Wart 19 volts 2 amps. Nice Lambda regulated power supply. I 
think it weighs around 20 pounds. I added #31 mix cores to the AC cord on the 
Lambda supply plus #31 mix cores on the 19v to each Monitor. 

The Test?  Transistor scanning radio that scans from LW up through VHF. While 
listening to the monitor and yes I can hear it a couple inches from the LCD 
screen 
but no farther than that. And Zero RF noise when listening to the DC line to 
the 
monitors or the AC line to the Lambda 0 to 20v supply.

[Elecraft] Data protection and recovery techniques

[kevinr]

Good Afternoon,

Recently there was discussion on backup strategies.  Here are my current 
methods.


I use three data protection strategies. The first is possible because of 
the way I design my computers. I use a small solid state drive for the 
OS and for all of the applications I use. Once everything is installed 
and all the settings massaged I make an ISO image of the drive and save 
it on my server. Then I clone a drive from that ISO and put it into a 
drawer. If I ever have a major OS crash I can pull that drive out of 
storage, install it into the box, and be running again in a few minutes.


The second method I use for data protection requires a versioning 
application. I use Subversion. When a set of folders with their 
attendant files is ready I create a Subversion repository to hold them. 
This repository is a database of files. Files can be of any type I have 
tried: C code, text files, CAD files, SPICE files, circuit board 
layouts, bills of material, etc. While I am working I commit my changes 
many times a day. If I need to recover a file from a week ago I can type 
svn update XXX and roll back my file system to when the XXX snapshot was 
current. I can also check out the repository to another computer and 
work on it. The first thing I do, when I start working on any of my 
computers, is type svn update. This pulls any changes from the 
repository and brings my files up to date. Then I write code, prose, or 
CAD committing the changes as I work. By typing svn update I bring each 
of my laptops and work computers up to the same revision number.


The third method of data protection is more common. I make copies of my 
files. I have found backup schemes which use compression or encryption 
get in my way. When I want to recover something it is not normally the 
entire system; I only need a small subset of the whole. So my backups 
consist of exact copies of files in the folder structure I built. If I 
need to, I can move entire chunks of the file hierarchy to recover from 
a major crash. For the most sensitive data I make a copy on the same 
computer but on a different drive and again on a separate machine.


The tool I use for this third method of data protection is a command 
built into Linux but available to Windows and Mac users too. Rsync lets 
me ‘push’ data from where it is to a remote location or ‘pull’ from a 
remote location to a local file. Rsync works across a network or across 
the Internet so you can have your files anywhere you have access. Linux 
provides me with another valuable command called cron. It is used to 
perform a task periodically, hours, days, weeks, months, etc. Once I set 
up a cron job I don’t need to worry about backing up my files. It all 
happens behind the scenes at whatever time of day I choose.


The first time you run rsync on a set of folders it copies the entire 
set. The next time it runs only the modified files are copied. Normal 
backup commands make compressed copies of all of the files in the chosen 
set of folders. Over time they build up a large set of files which are 
not readily accessible by humans taking up an inordinate amount of 
space. Rsync creates a mirror image of what your file system looks like 
right now. If you need one data file from the middle of that pile of 
files you can find it using your normal file system search mechanism. 
You do not need to decompress or decrypt anything. Everything is in 
front of you, easy to read.


I know this may seem Linux specific but it is not. That is just where I 
learned how to do this. Subversion, rsync, and a cron equivalent are 
available for both Linux and Windows systems and I suspect there are Mac 
versions too. The modern Macintosh OS is a flavor of Linux if you 
scratch beneath the surface. My first method of data protection is 
specific to how I build computers. Keep the OS and applications on one 
small drive while keeping all of the user created and collected data on 
a second, larger drive (or in my case across the network on the file 
server). The OS and application set do not change very rapidly so you 
can make a copy for later. The data changes on a regular basis so you 
need another method to preserve it.


Hopefully, these suggestions will help you keep your most precious data 
intact.


73 & GL with any hardware crashes,

Re: [Elecraft] Computer Monitor Recommendations

[Lyn Norstad]

The main computer in my shack is an HP Z800 Dual Xeon workstation with 2
Nvidia Quadra cards.  Originally I had it set up with 2 HP ZR2440W 24"
screens at keyboard level, and 1 Viewsonic 28" screen above (on a stand).
The Viewsonic died a couple years ago, and I replaced it with an LG 49" TV
(4K UHD - model UJ6300).  I split the 49" up into 4 logical 2k 24" windows,
so I now have the equivalent of 6 x 24" screens.  I can use it for multiple
purposes, including watching sports on the 49" screen (remember the days
when we had sports??).

The only issue I have is that one (just one ...) of the 2 HP ZR2440W
radiates a spike on 17 meters.  Not too serious, but rather weird.

On my 2 other computers, I am using 24" screens from "V7" a house brand of
Ingram-Micro.  No problems with either of them.

I recently had to replace my 6-year old failed monitor and I settled on
a 27" LG HD monitor  (the largest size that could fit on the desk)
because I didn't need 4K.  $159 at Costco.  It was the next-to-last on

Phil,

Did you unplug the  wall wart (or the monitor) from the wall? That PSU, 
whether external or built into the monitor, usually a major noise source.


ALWAYS, when offering (or evaluating) advice about whether some device 
is noisy, consider the possibility that the noise it produces is covered 
by noise from other sources in your home and in your neighbors's homes. 
Also consider proximity to ANTENNAS, not to the shack.


I work a lot of FT8 on 160M to work DX and on 6M to work new grids. The 
signal report is the signal to noise ratio. I run legal limit to very 
good antennas on both bands, and I regularly receive reports that are at 
least 10 dB worse than I give, telling me that most hams have horrendous 
noise levels.

Can you change the monitor/sidetone level?  How about the RF Gain?
If not, check the ribbon cable inside - unplug and reseat.
If still no solution, it is possible you have a bad encoder.

Re: [Elecraft] [KX3] Oppopsite Sideband Null question - Redux

So given that this is on a German blog site, I’m going to guess that it’s third

null depth found for each band/bandwidth combination or just run through them 
presuming everything else is hunky dory.

Re: [Elecraft] Computer Monitor Recommendations

[Rick Bates, NK7I]

I went with a 50" 4K TV (LG from Costco ~US$300) mounted to the wall 
behind the operating desk.  If your computer can manage 4K video (or 
even HD), LOADS of space to see (don't need my readers) and spread 
things out and being a smart TV, it has other features for the shack but 
I added a Dish Joey too.


I've been using full QRO, all bands, no issues in receiving, no 
artifacts on the TV and it's cheaper than a monitor plus it has speakers 
so the desk has less on it.


The new shack is still coming together, but it's looking better each 
upgrade.  (I'd send a pic but I don't think qth.net allows that, so I'll 
update my QRZ page within a day or two.)

These
are great monitors. We use them in the hospital. RF pretty much immune. No
RFI generation and great for reading and Logging programs. Plus, They come
with 3 sets of cables. HDMI, VGA, Display port. I have 2 of these mounted
on this:

. It has 6 usb ports, 3 type 2 and 3 type 3. More than enough for an SO2R
set up. 2 for radios, 1 for controller, 2 for separate keyboards and 1 for
mouse. No Usb break out boxes. Clean Setup. The Lenovo is hospital approved
for high rf environments. It is totally a metal box and works great for
logging, web streaming/browsing and light gaming, Guild Wars, EQ, WoW. It

Re: [Elecraft] [KX3] Oppopsite Sideband Null question - Redux

[Grant Youngman]

If you obtained this utility from Elecraft and used it, then you've done the 
opposite sideband null?  Did you observe any difference in the nulls at FL3 
bandwidths than you got with FL1/FL2 bandwidths?

The utility is probably one of many bits of automation ELecraft uses internally 
for test/manufacture that isn’t supported for customer use.  If I were going to 
run per-band nulling for 1000 radios it would be essential.  For one — the 
process isn’t all that bad :-)

Re: [Elecraft] Computer Monitor Recommendations

[Morgan Bailey]

https://www.amazon.com/gp/product/B075PMWCKS/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8=1
These
are great monitors. We use them in the hospital. RF pretty much immune. No
RFI generation and great for reading and Logging programs. Plus, They come
with 3 sets of cables. HDMI, VGA, Display port. I have 2 of these mounted
on this:
https://www.amazon.com/gp/product/B009S750LA/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8=1
 .
Then I took 2 band clamps to the pole and mounted this:
https://www.amazon.com/Lenovo-ThinkCentre-Desktop-i5-6500T-Windows/dp/B07QGLC4FW/ref=pd_rhf_ee_p_img_4?_encoding=UTF8=1=BPF1Q6NJ43K17FSHV78W
. It has 6 usb ports, 3 type 2 and 3 type 3. More than enough for an SO2R
set up. 2 for radios, 1 for controller, 2 for separate keyboards and 1 for
mouse. No Usb break out boxes. Clean Setup. The Lenovo is hospital approved
for high rf environments. It is totally a metal box and works great for
logging, web streaming/browsing and light gaming, Guild Wars, EQ, WoW. It
is my set up.

Best of luck in your choices.

Hi,
Elecraft have a handy little utility called RxSbNull.exe which does the whole 
process. All you need is an up to date KX3, an up to date XG3, a Windows 
computer and the utility. It works like a charm. Turn the radio volume down 
before you start it though otherwise it’ll annoy the hell out of you.

Re: [Elecraft] stripping insulation from enamel wires

[David Wilcox via Elecraft]

I have also used an electric solder sucker like this one:

https://www.ebay.com/itm/362348659918

You plug the end with the bulb and remove the nozzle.  Prop it with the opening 
for the nozzle pointing up and fill with fresh solder.  There you have a mini 
solder pot.  I bought mine for $10 or $15 back in the day and it works too. 

I still like my Knipex tweezers best but this is fast if you are doing g a 
bunch of toroids.  I would still use the Knipex tweezers to scrape the ash off 
if any is left.  Change the solder in the pot frequently.  The wire comes out 
tinned too, an added benefit.
