For a rainy day. 137 years of Popular Science free for browsing. Thanks PopSci and GooG. 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…] Surfing over to the Dell Outlet last week resulted in a moment of weakness. There were several bargain buys on Inspiron 537’s, 545’s, and 546’s. I settled on a nice Inspiron 545s, boasting 4gig of ram, 64 bit install of Windows 7, and a Dual Core Intel CPU. No extra “flufware” was installed on the system by the folks in Austin. The 545s is a low profile slimline system, so there not much room to add junk into it later, but at the Outlet price it solved an itch that has been begging to be scratched for a couple of years. New Hotness. After almost 10 years, the old Dimension 4300 is really dragging on normal day-to-day usages. So it is well past time where it should be put to pasture. It runs Ubuntu Linux well enough, but I have a lot of windows applications I use frequently, so XP has been king. The 4300 has a 1.6Ghz P4, but it is memory constrained at 512Mb max. PC133 memory(its that old). XP runs a lot of things well enough despite the system constraints, but is hard pressed to run the modern antivirus/firewall packages and be able to run a modern internet browser with all of todays’ superfluous and gratuitous visual content. Bloated OS, bloated security, bloated browsers, bloated web content. Itty bitty memory. Not conducive to a good user experience. Old-n Busted. So the Dimension 4300 is going to be a great file server, Linux experimentation platform, and all around backup contest logging box. Just in case the really old and busted CPU in the shack croaks… It is hardly a shock to find that the New Hotness is pretty damn nice. Everything is relative. Windows 7 is taking some mental adjustments. Ten years of XP have worn big habitual ruts in the gray matter. But there are a few nice surprises under the hood of Win7. Anybody using/administrating Windows 7 should goog up “GodMode”, a nifty but undocumented control panel quick-list. The MS-geeks should have made it a documented feature. Also, the whole system is just blazing fast in comparison to the old. The on-board graphics are quite sharp, and seem fast enough for daily use. Probably not a video gamer’s box, but certainly fine for general usage. Ten years from now – who knows? One quirk that took a moment to adjust to was finding the directory being used for storing program data. Many XP applications defaulted to storing program data in the program’s directory. Under Win7, the application’s program directory is protected. To get around that, data files used by an older application are shunted into a directory under the current user. A bit of head scratching and cussing later, the location of that directory was found to be defined by the environment variable “appdata”. After a bit more head scratching it became clear the “appdata” folder was indeed under the user account, but it is a hidden directory. To get to it directly you can hit ‘Start’ and type %appdata% into the run/search box. Or you can just enable the file explorer to see hidden files. Grrrr. Not sure why it ever made sense to RedmondGeeks to hide the application data…… So far I’ve only run into a couple of minor problems installing software on the 64 bit OS. I decided to define a separate admin account, and set up user accounts for everybody as users without admin privileges. General applications can be installed by running the install as an administrator. This worked well for most applications. Two glaring exceptions to that generalization: Security software, and Google’s browser. The security software is understandable – that is best installed by the administrator directly. But there’s no legit reason Google’s browser should be such a pain in the ass. And pain in the ass it is. Running the install of Goggle’s browser as a user with “run as administrator” resulted in no visible installation. The install program runs, then ends without any messages/ warnings/ errors. Backing off on that, the install was run directly from the admin account. In that instance the install succeeds – almost. After that installation, the browser was available under the administrators log-in, but not to any users. The install did not offer an option to choose users. Somewhat less than satisfactory. So for the moment, Google has been kicked from the New Hotness. Banished. Shunned. Deposed. Rejected. What with IE/Firefox/Opera/Safari all working properly, its not like there are no options. On the browser front, it has been nice to be able to get back to using Firefox regularly. Firefox had become really bloated since I first used it – it is a real performance pig on the old-n-busted 4300. Having adopted Firefox early on, it was really disappointing to see it become fatter and slower than IE. Over the last 18 months Opera has been the preferred browser. Opera has been an off-and-on affair over the years, since it has in many cases been the most innovative of the browsers. In previous incarnations rendering of web pages was not always as reliable as the others, but it has always been the fastest of the group. Since the more recent editions of v9.xx and now v10, it is both fast and consistent. The Firefox performance issues on a low resource system seem to be a script related problem, although the sites with a ton of images are always slow too. All of that probably relates to the memory constraints, system paging, thrashing, and the intrusive nature of modern antivirus applications. Running without the AV software speeds it up in some cases, but the hardware limitation is a bigger problem. The 4300 box at idle uses almost half the available memory in that system. The New Hotness zips right along. Sweet. The New Hotness can support up to 8gig of ram. I expect to stuff it to the limit to allow room for tinkering with virtualization(VirtualPC, Sun’s VirtualBox, etc.), and maybe a bit of low end graphics card upgrade, if a decent low profile card is available at a bargain price. Set for another decade – maybe. The idea of a wireless headset that can be used for contesting is one that I have discussed with several folks over time.  Kicking around ideas, none of the Bluetooth sets seemed suitable.  Battery life and charging options with most Bluetooth headsets seem too limited for use in a contest setting. So, where might something more suitable be found? It would appear that the online gamerz have a similar need, and at least one vendor is going to scratch their itch.  Creative Labs has a headset being marketed to the “WoW” crowd*. It is called the “Creative Sound Blaster Wireless WoW Headset”.  The “Tom’s Hardware” computer site has a short review. The review indicates it is a comfortable headset, uses USB for computer interface/charging, and is 2.4Ghz wireless technology rather than Bluetooth.  The Creative spec sheet shows a 112db SPL in the cans, and there is a volume control on the headset itself.  It would probably make an ideal wireless set for the contest operator – except for the $160USD price tag(listed$159 @TigerDirect).  But these gaming headsets have a tendency to drop in price over time, and if another vendor follows suit that price will likely drop. I’m assuming that many “WoW”  gamers remain attached to their entertainment nearly as long as a contest operator keeps his Butt.In.Chair. The features description indicates the headset can operate while attached to the USB charger.  It should be a trivial hack for a ham to rig an outboard battery pack to supply the same 5v that would be supplied by a USB dongle.  Then it would also be simple to use with a logging program in a station set up to voice key via the computer.  There is also a dongle for a PTT footkey, that can be mapped to the keyboard. It even has runes inscribed into the sides of the cans for that bit of supernatural DX’r mysticism, guaranteed to have that rare DX hear your 5w SSB signal when fed to the bedsprings. *NOTE: For all you old geezers, “WoW” is an acronym for World of Warcraft, an online video game played by millions of gamerz world wide. The Who Dats rejoice.  Bag Heads no mo’. [at least until August] ….Billy Kilmer….Tom “Gut” Dempsey…Archie Manning….Danny Abramowicz….Ricky Jackson……Sam Mills….Bob-bey…..Fears-Stram-Phillips-Mora-Ditka-Haslett-Payton….vs.Rams_vs.49’rs_vs.Falcons……Campbell-Rogers-Hilliard-Gajan…,,Superfoot, Morten Anderson…..Lots of interesting players, and interesting moments.  And all too many moments best forgotten. And after only 43 years, an entire year of highlights all in the same year. … Close call. The end of December was a maelstromof new sunspots when compared to the previous 24 months. Hope springs eternal. The activity in the last couple of weeks of the year were enough to preserve 2008’s second place ranking in the list of “most spot free” years. But 2009 is in firm grip as number three on the list. If the spot trend were to continue unabated, that would put the minimum somwhere around January 2009 – though without more research, I can’t recall if that iswhen the first cycle 24 mini-spots appeared. Seems about right. The 3 month moving average is also going up, another bit of good news for the radio geeks. Plots of cycles 1 through 23 indicate the numbers ramp up at a higher rate than they drop off, but that is more pronounced in the cycles with high peak numbers. Given how poorly the prognosticators did with predicting the minimum, I suspect the next peak will also be hard to predict. My own W.A.G. is a peak of around 90 sometimes in 2013. O’course, a Wild Guess ain’t none too scientific. But there ain’t a whole lot of data gathered on a system as complex as the ginormous fusion bomb going off 24/7/365 over the last four billion or so years, only “one AU” away. So I stand by the guestimate proudly, without hesitation. O’course, I must admit to being distracted byWired’s link to nerdeye candy over on their web site. Yikes. Or in nerd-speak, “OMG!”. Sometimes procrastination pays off. On W7IUV’s web site, he has a link to his “W7IUV preamp”. The document was revised a few months ago, and it includes schematics and parts lists for both versions, as well as a general discussion on the preamp. It appears that no suitable surface mount parts were found to replace the transistor. Not like I want to play with surface mount components anyway. 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? These items washed ashore on the most recent web surf. Not really related to anything I generallylog regarding the KazShack activities, but some of it caught my interest enough to save the links here rather than get lost in the BookMarkMultiverse. A useful chart of the evolution of storage. It unfortunately omits Hollerith punch cards,cassette storage, the 8 inch floppy, tape drives, or the old mainframe removable spindle drives. Gotta draw the line somewhere. This is just plain cool, and its available as a kit. The LED Bulbdial Shadow Clock from EvilMadScience. Way cool. These would just be fun to slap on a jewel case of any program. Originally issued for Vista I suppose, but fun to slap on the kid’s PC games – just to see if they react. Be great back on the floor of tech weenie cubicals too. DAMN! Somebody stole another one of my ideas. Well, OK, I suppose they arrived at the same mental junction independently, but if I still had access to a welder, I’d have made some already. 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. |
