Windows 7 GodMode

Leave it to the RedmondGeeks to create a useful tool but leave it undocumented rather than make it easily available.  And a big thanks to NumberOneSon for showing me the trick.

There’s a feature for Windows 7 users called GodMode, which is simply a tool/folder that has a lot of the more useful system administration tasks grouped together in one place.  [As opposed to navigating five screens to get to them.]

All that is required to use the feature is to create a folder then re-name it.  See the link for the details or just goog up the word “godmode” for yourself.  No use re-inventing the wheel here.

[hey!  I didn’t name it…]

Installing Writelog Under Windows 7 UAC

OBSOLETE:  Versions after version 11 are much better.  Disregard if using a version of Writelog after 2011. [w4kaz, 20150101]

ENVIRONMENT: The following applies to an install of Writelog on a Windows 7 64 bit platform with User Account Control enabled.  Probably works for any Windows 7 version.  It may also apply to Vista, but that version of Windows has not found its way into my hands, so experiment at your own speed.  All installs were done under the administrators account, and testing of the application done in a limited user account.  No special permissions were granted to the limited user, nor to any of the directories.

BACKGROUND: The new BlogBox is not used down in the KazShack dungeon, but  is the day-to-day computer.  After a contest, I move the log file up to the main computer and use an install of WriteLog on that box to spew out the Cabrillo, and ADIF backup, and the reports.  For my own nefarious reasons, I chose to set the new BlogBox up with an administrative user, and do all of the day-to-day activities within a limited user account.

WriteLog is still backwards compatible with older versions of windows, and runs well even on systems with limited resources.  That is something that is a useful feature, as it allows a wide  choice of hardware platforms to be pressed into service.  Plus, I just damn well like WriteLog better than anything else.

But since Writelog was designed before the day of user accounts there are some adjustments that need to be made to get it working in Windows 7.

THE INSTALL: One approach used by many is to disable User Account Control[UAC] and run the system as the administrator.  That’s a judgment call.  Diametrically opposed to the goal here…but used with success by many.

Another approach that seemed to work is to install it under an account with  administrator privileges.  But that also falls short of the goal, which is to get it going under a limited user account.  When installed as the administrator, the user accounts were able to run the program, but not able to save the configuration settings.

The approach that seemed to work is to install WriteLog into its own directory[I named it c:\writelog_install_home].

The install went without a hitch.  The real trick is simply to find where everything is right after the install.  The important part is locating the “writelog.ini” configuration file.  For whatever reason the RedmondGeeks in Windows 7 [and maybe Vista] have an environment variable [“appdata”] that is used for hiding certain bits of data under UAC.  The term “hiding” is used deliberately since the directory referenced by the environment variable is indeed hidden.

Finding STUFF:

  • start a command prompt window, and type “set” with no other parameters.  that will display all of the environment variables. The pertinent one is “appdata”
  • In the file explorer, under “organize” –> “Folder and search options” –> “View” -> “Hidden files and folder”  check “Show files, folders and drives”
  • In Windows 7 user info/program data is generally is stored in “C:\users\xxxxxx”, where xxxxxx is whatever your user name might be.
  • Writelog creates a directory in the “c:\users\xxxxxx\documents” directory[i.e., “My Documents” under the logged on user account] for its data files, wav files, contest “ini” files, etc.

The basic install is all pretty easy once you locate the files.  The critical file is the configuration file, “writelog.ini”. In this sort of install there are actually two copies of writelog.ini.  One copy is in C:\windows.  That copy is an abbreviated version, which has what I expect are the bare minimum bits of info required by WriteLog to run.  [NOTE:After installing the program several times it is possible this copy in C:\windows could just be cruft left in place from a previous install.] It seems likely that “writelog.ini” is used to initialize the program.  Probably best to ignore that copy of Writelog.ini, and leave it undisturbed.  You will need to have admin privileges to edit it.

The second copy is stored under the c:\users\xxxxxx\appdata directory in the sub directory \VirtualStore\Windows.  The full path in my install was “c:\users\w4kaz\appdata\VirtualStore\Windows\writelog.ini”.  THIS is the file used to store config settings for the logged on user, and it is here that customizations should be added.

The user copy is created for each user individually and uniquely. That copy is the version that can be customized as required for the particular situation.  A lot of WriteLog users have custom versions of their config file for different situations.  Rather than maintain numerous copies of the file, it might also be appropriate to define a separate user for each situation.  Then all of the copying/management of config files could be avoided by simply logging on to the appropriate user.

That’s enough to get the program functional as far as opening logs, exporting reports and files.  Testing connectivity is to peripherals is more difficult, since the shack is not in the same location and there are no USB dongles yet in use in the KazShack.

The defaulted directories were as follows, after the user had opened the program, and done a “save config”:

[Install]
Directory=C:\Program Files (x86)\WriteLog\

[Configuration]
WaveFileLocation=C:\Users\w4kaz\Documents\WriteLog\WaveFiles\
RecordingLocation=C:\Users\w4kaz\Documents\WriteLog\AudioRecording\
DataFiles=C:\Users\w4kaz\Documents\WriteLog

[Multipliers]
Location=C:\WriteLog_install_home\Programs\

Wave files and data files are defaulted to the user’s documents folder.  Customize those as needed.

The only real curiosity is that the user writelog.ini install directory was not updated in the final install to reflect the actual install directory.  Its probably best to update that entry to reflect the actual installation directory.

Installed in this manner I have not yet run into anything that required administrator privileges, or that Writelog be “run as administrator”.  But admittedly, I have not yet tested  keying CW, .wav file audio, or rig control.  The BlogBox is not the computer used for contest logging, nor do I use any USB dongles at this point.  In the end, admin privileges may indeed be required for full featured usage that bangs away on the com ports, but in a limited use it is not required.  Best guess is that LPT keying probably is more complicated, if possible at all, and that a Winkeyer would probably work easily via USB.

CAVEAT: After I was satisfied the main program was functional, I went through the Writelog directory and executed each of the utility programs.  The  “tuning indicator and audio snapshot” program received an error window trying to edit the system registry.  That program is for use with RTTY, a mode I am not using, so it is not clear to me that the program has actually failed.  After acknowledging the error, the program appears to load and be ready for action.

UPGRADES: For these tests, Writelog v10.70c was used for the full install.  Upgrades 10.71 through 10.75 were then applied via the administrator, with no problems encountered.  The program ran for both the administrator and the limited user accounts.

And dats da fax, jack…..

ARRL DX SSB 2010 – Who Is The Competition

This year N1LN has been able to find enough operators to be able to host a M/2 effort for the ARRL DX SSB contest.  I am fortunate enough to be part of the SSB team this year, and I’m excited about the opportunity.  This is a great DX contest, as the DX stations are seeking to work the US stations.  If we are fortunate enough to have good operating conditions, it should be a blast.  Good 15m or even a chance 10m opening would just make everything better. If the conditions are anything like this past weekends’ DX CW, we are going to have a great contest and a lot of fun operating.

Looking at the 2009 results, it appears we have a real shot at creating ripples in the M/2 pond.   For 2009 the top 10 in the W/VE M/2 class were:

1	WE3C	6,019,992	4,167	484	EPA
2	N3RS	4,507,461	3,461	441	EPA
3	W4RM	3,431,106	2,857	406	VA
4	K8AZ	2,759,328	2,308	402	OH
5	NR4M	2,565,171	2,170	399	VA
6	KB1H	2,518,431	2,191	391	CT
7	NE3F	1,984,140	1,861	365	EPA
8	K0TV	1,793,412	1,623	372	NH
9	W5WMU	1,654,044	1,459	388	LA
10	NK7U	1,312,464	1,491	296	OR

Operating during the CQ WW SSB contest, we managed just over 3000 QSO’s.  In better conditions, it is likely we can do better than that.  But so will everyone else.

After looking at the descriptions of some of the other stations[see links above], its a tough task to join this crowd.  All of these stations have larger antenna farms than that at N1LN. Most of the top five have towers over 120′.  WE3C has a high 80m rotate-able dipole, as well as 4-squares for 160/80/40. Most also have superior geographic situations working in their favor as well.  The promise of good conditions may also lure some stations back into the M/2 category. The poor conditions of the past few years must certainly have caused some to drop back to a single transmitter.

We can also hope that ‘other factors’ will NOT be equal.  But the chances of bad weather are probably higher in this part of the US than in these more favorable locations.  That is not a controllable factor. So it is probably best to think of things we might do to improve our performance.  Maximize multipliers.  Dig out the weak ones.   Be on the right band at the right time. Rate is king.  Butts in chairs.  A couple of cold 807’s to keep ‘YDU’s pipes going for the duration.

Should all other factors be equal, if we are to cause ripples in this pond we will need to be better operators than the other guys.  I’d like to think we can at the very least keep them looking in their rear-view-mirrors.

“No sweat!” [HA!]

2010 ARRL DX CW – What A Difference A Few Sunspots Make

The propagation conditions were better to EU than its been for quite a long while.  That made the contest a lot more enjoyable than the DX contests have been over the past few years from here in the “cheap seats”[low power into low dipoles].  I’m sure the scores at the big stations will reflect the changes.

For my own part it went quite well-even with a small station

In the week before the contest, conditions were sounding good, with good openings on 15m and 20m.  There was no real plan to put in a heavy effort here, but instead to have fun and get in some CW practice.  Check.  Mission accomplished.

Overall, with conditions so much better it was easy to stay in the chair longer than planned. 15m opened early on both days, just after local sunrise.  20m was hot in the early afternoon, and 40m and 80m both opened to Europe earlier than I usually notice.  There were even a few QSO’s on the edges from 160m and 10m.  The 160m Q’s were early in the evening, when I was hearing a few EU stations, but they weren’t hearing the dulcet tones emanating from the Kazshack.  The 10m QSO’s were very fluttery, with lots of QSB, but worth chasing anyway.

The operating plan quickly morphed from “Search and Pounce” into finding a place to try to run.  The original idea was to operate “unlimited” and play “S&P2R”.  The network connection never got connected after tuning around a bit and shifting the gray matter into run mode.  Wedging into a good spot is always a problem, but once found the good conditions had the stations lining up.  Sometimes too many – a new experience from the KazShack.  But good spots were hard to find and a lot of time running was done at lower rates up in the “nosebleed” areas higher in the band.

The runs brought in a lot of surprises.  On 40m finding and working the KH6 was a surprise, as well as being called by a TA and a ZC up on 15m .  Early on the second day I also found a JA1 on 40m, but no joy – working left coast.  Some of the surprises were unusual enough to cause the brain to balk on copying the call sign correctly – V51 in particular.  A search and pounce sweep on 10m and 15m bagged ZM1A on 15m,  as well as five of the 10m mults.

15m showed signs of signals from Europe just after local sunrise, and they were able to hear me soon thereafter.  Probably an hour or so earlier than that for the stations with good 15m antennas.  But the lack of good antennas served to limit the volume of responses rather than shut the band to use.  I was able to run stations on 15m after 1230z on the second day.  Just a couple of hours later, and 20m became hospitable for a low power run above 14100.

Being a fan of 15m, not much time was spent in the local evening hours.  Its difficult for the DX to hear the 100w stations through their local QRM and QRN.  With 15m and 20m open, that’s not the disaster it has been in the past couple of years.

It will be interesting to see the scores and compare them to those of the past couple of years.

The Good:

  • Conditions!
  • More like fun, less like work
  • Decent runs

The Bad:

  • Problems with copy on unexpected calls
  • Pile up skills

The Ugly:

  • Possible problem with K2 KAT100 auto-tuner on Ant1, used ant2 for duration of the contest

W7IUV PreAmp in RX System

After building the 80m/160m splitter, it seemed like the signal levels from the K9AY were down a bit, probably from losses in the filters.  So after looking around at pre-amps, and procrastinating on buying the Ar2 preamp, I again landed on the W7IUV site.

W7IUV has updated his preamp schematic, and it looked easy enough.  Building the project was simple after gathering some suitable parts.

Trying the pre-amp out seemed to show that it was more or less filling the desired role quite well. With the preamp engaged, levels from the K9AY were now on par with signal levels from the transmit antennas on both 160m and 80m.  The preamp is installed in the shack just ahead of the band splitter.   Noise levels on the RX system were down about two to three S units from the TX antenna in these moderate noise conditions.

During the 160m contest this weekend, the RX system got its chance to proove itself.  Noise levels here were moderate – not as quiet as good winter conditions, but not S9+ summertime noise either.  The RX antenna with the preamp turned on was always the best choice on weak signals in these conditions.  It also necessary to switch the K9AY around a lot – signals were not always best in the expected direction because of higher noise to the north.   The southeast direction was dead quiet, but from here in central NC there isn’t much to listen to on 160m to the SSE. The actual compass direction on the SE leg is about 10 degrees south of southeast.

So the short version is that the preamp is an improvement when splitting the RX antenna for two radios.  

Future projects/curiosities:

  • Try moving the preamp out to the base of the K9AY, probably in a new K9AY switch box
  • Test the RX with the splitter removed, preamp on/off.

 

NAQP SSB January 2010 @ NC4KW

Once again N1LN and N1YXU hosted the January NAQP’s at their home, and I was happy to be part of the SSB team. This year’s crew was N1LN, N1YXU, AA4FU, and myself, W4KAZ, operating under the NC4KW call sign.

It was a lot of fun.

Given the poor high band conditions over the NAQP CW weekend, there was a general agreement that the best initial plan might be to start on 20m and 40m, with the intent of keeping an eye on 15m and 10m in case of any possible openings. That proved to be a worthwhile strategy. We once again turned up a big ‘goose egg’ on 10m, not logging a single qso on the band. N1LN was able to improve last year’s 15m qso count with a short run and some S&P on 15m during his first shift and in between 40m runs.

20m was never great, but we brought our 20m qso count up to a more reasonable level, a big improvement over Jan 2009 contest. Conditions on 20m seemed really long right at the start of the contest. The upper antenna at 100 ft seemed to always be the best choice, and there seemed to be a narrow patch of good propagation into the upper midwest. Logged a bunch of Minnesota stations, and picked up a few other odds-n-ends from Minnesota westward. The western gulf coast from Louisianathru Texas were also being heard, but their signals were only half as good as Minnesotans. At the end of the first shift n 20m, there was not a single qso from sections 1, 2, 3 or 4. A somewhat lackluster result on 20m, at least for my own time in the chair on that band.

The other bands were also all improved over the 2009 totals, with better qso counts on each band. The multiplier counts were also better. The 80m mult count was tied with our 2009 efforts, but we improved our mults on 160m, 40m, 20m and 15m.

By coincidence, I wound up taking over the chair for 80m, and later 160m atjust the right time to begin trying to start runs on those bands. The first hours on each of those bands was interesting, with decent rates. For whatever reason, the beverages were showing a high noise level in the north and northeast directions. That made working the high population areas to our northeast more difficult, especially since so many stations calling were down at the noise floor. The 8’s, 9’s, and 0’s made up some of the slack, as they were easier to copy on the west and northwest beverage directions. The noise level began to decrease after local midnight, but rates had slowed by that time.

Some of the operating highlights were opening on 80m and 160m, and seeing the 60 minute rate meter[both stations combined] over 150, working with N1LN to get the 10 minute rate meter over 200, and then trying to keep it there. Later in the contest, 1400 Q’s became the short term goal, but N1LN caught a late burst of Q’s on 80m that put us over 1450 by the end of the contest.

In hindsight the total of 1469 qso’s logged is a new personal milestone. It is the first time I’ve been part of an operation that averaged over 60/hr for the duration of the event. [1469/(2*12)=61.2/hr]

Sweeeeet!

2010 NAQP CW – January

Nothing great, but not too shabby. 352 Qsos total.

Conditions and observations: Early in the contest conditions seemed poor to me, but perhaps I was just in the wrong place at the wrong time. At the start, I tried to get a run going on 20m and use the second radio for S&P, but neither was working well. The run radio was slow on the 20m dipole. I guess all of those tri-banders out there have the advantage. 20m seemed long from the start, as I was called by a strong AL9A. Alaska is unusual so early in the afternoon on my dipole.

The S&P on 15m was none too productive either. There were a few stations there, but lots of QSB. Most seemed to give up calling on 15m pretty quickly[or vanished due to changes in propagation]. Nothing heard on 10m, but not a lot of time listening there either.

It is also obvious that I’ll need to become a much better operator before using the second radio during a run is practical. Even a slow run. But the NAQP’s are the perfect contests to use as a test platform for learning SO2R techniques.

On the other hand, S&P with two radios was a lot more productive than S&P with a single radio. Better than using a single radio and loading the band map. With two radios, the utility of the second band map also comes into effect. The rate went up as soon as I switched from running to all S&P. I didn’t hit my goal of 60/hr while S&Ping, but it is a goal within reason, and it was easy to keepa 40 to 50 rate with two radios without much stress.

Thats the first couple of hours. The late afternoon was broken up into S&P fragments, capped with a hour long 40m run from 2220z to2320z. Then another gap peppered with a handful of quick S&P Q’s and a break for a sandwich.

Shifting down to 80m, I S&P’d my way to a mostly clear frequency at 3563.75, and thenheld a two hour run there from 0100z to 0300z. While the rates were meager for somebody like Bigg Gunn Kontester over at the Fi-Ni Report, both those hours on 80m were over 60/hr. I gave it up soon after W4HSA called me, and I just could not get his call correct, even when he resorted to sending his call suffix at about 5wpm. Such is life in LidVille. Duh-OH!

Still short of 300 Q’s. Tuning around 40m was discouraging, as the band sounded really long and there were not a lot of stations calling. 80m seemed like mostly dupes, so on a whim it seemed time to check conditions down on 160m.

The 160m antenna was playing well again. There were only three stations that were called with no answer. Soon enough stations were S&P’d to get to 340 Q’s in the log.

A few more passes on 80m and 160m, and the plug was pulled at around 0400z withjust over 350 logged. The total time on the clock was about 9 hours, but a lot of that was spent away from the radio in increments more than 5 minutes, but less than 30.

The Good:

  • Just over two consecutive hours with rates over 60/hr. First time I’ve had two such hours back-to-back.
  • 160m antenna continues to function well

The Bad:

  • A moment of Murphy when switching to 80m. The kludged-together band pass filter switching resulted in a few moments of angst filled debugging when it appeared the 80m antenna was showing a high SWR. [Operator Error.]
  • No productivity early in the contest.
  • 20m slow.

The Ugly:

  • Total mental shutdown trying to copy W4HSA. Too bad it can’t be blamed on being exhausted or a weak signal. Nope. Just a lid moment here in the KazShack.

Recycled Radials

Finally figured out what to do with burnt out strands of Christmas lights. Scavenged about 100 ft of wire in 20-25 foot long hunks and used it to augment the radial system on the K9AY.

The K9AY RX antenna itself is in need of replacement. It is constructed of 18ga wire, and has had several breaks in the past couple of years. Right now it has five or six splices where repairs were made. Probably time to replace it with 14ga THHN, now that copper prices are down again. A 500ft spool of 14ga stranded THHN housing wire was $35.00USD yesterday at the local BigBox retailer.

Time to stockpile before hyperinflation kicks in?

Empirical Evidence On Longevity Of Bare AL Radials

Finishing up on the yearly mess of litter generated by the biological antenna supports was much more painful this year[literally]. The wet weather makes dragging large quantities of sopping wet leaves a real chore. Messy too. Using a leaf blower here is equivalet to bailing the Titanic with a teaspoon. Futile. The massive quantity ofvegetative miscreants combined with a gentle uphill slope renders the leaf blower useful only for clearing small areas. Maybe a chainsaw…..

During the process, two of the radials on the K9AY were “discovered” to be broken. [Ooops!] The radials were simple 17 ga. AL electric fence wire, purchased for a pittance in 1/4 mile quantities from the local farm supply. These radials were in direct contact with the soil. Soil testing a few years back showed the PH to be about 5, slightly acidic. No real idea of the chemical/mineral content, which I expectis probably a bigger factor than the acidity.

These radials have been in place for about four years. I broke both of them while raking leaves. A closer examination showed that the portions of the wire in direct contact had become quite brittle. It took little pressure to break them this year, although they withstood similar abuse over the past three seasons. A closer look showed the aluminum to be getting flaky in spots, and it had zero ductility. Even an easy bend was enough to break the wire in those areas of heavy oxidation.

Not too shocking a discovery, but worth documenting. Aluminum radials are good for about three or four years on the soil surface – in this yard.

Conversely, the three year old elevated radials on the inverted-L were inspected just before the 2009 ARRL 160m contest. These seemed to be in fine shape, with no visible signs of oxidation and no new breaks despite catching a few falling branches over the past year.

Sothe K9AY radials will be replaced with chunks of the equally cheap WD-1A surplus “field wire”. May as well see how long that lasts too.

2009 ARRL 160m

Got a chance to work on the matching network for the inverted-L, adding in series capacitance, a choke, and balun. This gave me a good match at about 1840, and the SWR was decent from 1815 up to about 1860. The results seemed to be an improvement in the chances of being heard by most stations. That’s with just 100w. Decent results, given the low power and inefficient antenna.

Got in three really nice runs. The first was disrupted by another station sliding in. That was annoying, because the 10 minute rate was up over 100. After I moved, I settled into a nice 40 minute run that finally pooped out of its own.

There was only a limited amount of time available, so the periods from 2300 local “until” were chosen from both evenings. There seemed a whole lot less activity on Saturday evening. Logged about 3 hours and 130 Q’s Friday night but only 2 hours and 70 Q’s Saturday.

Found KH6ZM working a big pile-up on Friday night. Listened to that for a while, but I only heard him work a couple of east coast stations. The west coast and mid-west were pretty thick, so I didn’t waste time. Tuning up the band I found HI3 calling with no pile-up. Also worked a G3 and a few Caribbean stations.

The K9AY made the difference on several Q’s. The noise wasn’t bad, but There were a couple of relatively weak stations that really peaked on the K9AY but were in the noise floor and not copiable on the inverted-L. Armchair copy on the K9AY. Interesting. Many others were easier copy on the xmit antenna. Also interesting.

The matching network is another great application for a relay box, so I can have a good match at selected parts of the 160m band. With low power, the 3KV panasonic capacitors seemed up to the task, and I saw no signs of the SWR shifting when running, so I presume they are able to handle the 100w level. With several in parallel they seemed to handle the current. Given the bandwidths I am seeing, resonance points at 1815, 1840, 1865, 1900, and 1930 should serve the purpose.

Station:

  • Elecraft K2, 100w, into inverted-L and four direction K9AY rx array

The Good:

  • The matching network changes worked.
  • The inverted-L improvements seemed to help the station to be heard, but there’s no easy way to quantify that.
  • Rain shield added to cover feedpoint held up to nasty WX.

The Bad:

  • Not enough time available to operate.
  • Missed the start of the contest.

The Ugly:

  • None!
