Hamsphere: Virtual Ham Radio transceiver on your PC

Hamsphere simulates a full blown virtual Ham radio transceiver on you system. It can be operated by licensed and unlicensed DX’ers for free. If you are not having Amateur radio license, they will issue you a “call sign” while registering.

What is so great about this Ham Radio Software Transceiver?

No extra hardware needed, just your PC, a microphone, speakers and you are ready to call CQ on the virtual Ham Radio bands.

You can feel audio on Hamsphere with simulations of occasional band noise and fading, as in a real radio transceiver. The user interface looks like a real HF transceiver


If you are interested in becoming an Amateur radio operator, here is the opportunity to practice it without buying costly amateur radio gear.
Forget about building complex antennas, raising it on high mast, antenna tuners etc. All you need is an Internet connection and Java support.
Voice (SSB) and CW (Morse code) are allowed on most bands. On the lower bands we can turn on/off(noise-free) the simulation.

Digital modes were prohibited on HamSphere earlier, but are now supported on the 30m band. RRTY, PSK31, SSTV etc can be used.

Pre-requisite: Download JAVA

Download Hamsphere (Windows, Mac and Linux )

DmiDecode for Windows

The MS-Windows port of the popular Linux tool can be used in Command Line Interface (CLI) of Windows (XP onwards).

Dmidecode reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard.


Download DmiDecode

Install it, then you have to set the path

open a command line window and type

path=C:\Program Files\GnuWin32\sbin

if it is installed in C:\Program Files\

Three additional tools come with dmidecode:

  • biosdecode prints all BIOS related information it can find.
  • ownership retrieves the "ownership tag" that can be set on Compaq computers;
  • vpddecode prints the "vital product data" information that can be found in almost all IBM computers

Now you can execute commands

dmidecode –t x

where x can be

  • 0 – BIOS
  • 1 – System
  • 2 – Base Board
  • 3 – Chassis
  • 4 – Processor

Cant Open File Because of Access Permission in windows? simple solution

Today i was surfing my favorite Orkut community OUG13 as usual and i saw a very strange problem. A gus names "Agent X" was facing this problem that he was not able to open any file and it was giving error as shown in the screenshot


Many people tried to help him but finally solution given by untitled worked. The simple solution was to download this reg file and install: http://bit.ly/c0pmEs and it worked. By the way the filename is takeownership.zip . Thanks for sharing such an easy method with us 🙂

Using the Recovery Console in XP

If you cannot boot into safe mode you can try using the Recovery Console in Windows XP. This requires you to have a Windows XP CD. Knowledge Base Article 307654 has directions on how to use it. You do not need to follow the instructions for how to install it. In fact, if you have a problem like the 0×00000024 issue above, you probably can not boot from an installed recovery console anyway.

In brief, to boot from the recovery console in XP, do this:

1. Insert your Windows XP CD
2. Boot the computer
3. Select to boot from the CD. On many computers you have to hit a button to do that. On Dell computers the button is usually F12. On HP it is usually ESC.
4. The computer will work for a while and eventually you get a screen that says “Welcome to Setup”. Hit the R key here
5. If will ask you which installation you want to boot. If you have several XP installations on this computer, select the one you want. Of course, if you have several installations, and one still works, you would not need these steps.
6. Type the administrator password for the installation you need to repair.

At this point, you should be at a command prompt. The commands you can run are very limited and they are often different from what you are used to. If you have disabled the intelppm driver on an Intel-based computer and need to re-enable it, run “enable intelppm SERVICE_SYSTEM_START”.

If you need to run chkdsk you can do it from the recovery console window as well. The C: drive is the boot volume in your Windows XP installation. To run the full check run “chkdsk c: /p /r”

Simple Ways of Speeding Up Windows Vista

Windows Vista is a rather heavy operating system with many neat features, but unfortunately they come at all in price. Right out of the box it requires a pretty hefty system to run (arguably).

Before you run out and buy a new computer just so you can run your base operating system, check out these Simple Ways To Speedup Windows Vista tips to lighten the load. This is just the first in the series, so many of them may be very apparent to those experienced in tweaking.

1. Turn off UAC, or at least make it less annoying

Now, there € ™ sa lot of talk about the new user account control policy in Vista, and all I can say is: as it is, it annoys the hell out of me and slow down my normal computer usage. Just why, oh why, does it have to flash my video card to a black screen, take 5 seconds and really just make itself a royal pain in the arse?

To turn it off, the easiest way is to go into the Control Panel and type in ‘UAC’ into the search bar. Ita € ™ ll bring up a search result of â € ~ Turn User Account Control (UAC) on or Offa € ™. Just follow the prompts from there.

To keep some of the security of the UAC, Leta € ™ s just turn off the crazy annoying blacking out screen bit. To do this:

     * Open group policy (start | run | gpedit.msc)
     * Then navigate to Computer Configuration | Windows Settings | Security Settings | Local Policies | Security Options
     * Find the policy named â € ~ User Account Control: Switch to the secure desktop when prompting for elevation € ™. Set this to disabled.

Much better, eh? You might say â € ~ But what € ™ s that got to do with speed? Â € ™ Well, as I mentioned, it prompts me a couple times at least an hour and then takes several seconds to figure itself out. My productivity goes up, so ita € ™ sa speed enhancer;)
2. Disable Aero

I personally do not do this, as I am a fan of the graphical styles, but I realize it comes at a cost. It does tend to eat up both RAM and CPU usage (as well as video card usage). While it is turned off during gaming, you can still notice its effects during normal computer usage. When it is really cranking, it can use 15% of your CPU. Ouch. Vanity comes at a cost.

If you do like it, at least turn it down a notch couple. Some performance increases have nothing to do with strain on hardware, or amount of processing. Sometimes, things are designed to take longer than they should, though maybe only a fraction of a second, but the end result to the user is a faster machine. Minimizing and maximizing does an animation. Watch closely. Pretty quick eh? Still, it does slow you down, and, really, what does it add to your experience? I am all about vanity and aesthetics, but this feature has got to go.

Relish in the fact you will be increasing your productivity by 0.2 seconds to Minimize / Maximize. 🙂

     * Open your start menu, go to Run, and type in ‘systempropertiesperformance’
     * From the Visual Effects tab, uncheck “Animate windows when minimizing and maximizing ‘
     * While you are here, might as well check out the other goodies you can disable.

3. ReadyBoost

ReadyBoost is one of the more innovative features of Vista. The idea behind it is to use solid state memory as a secondary memory cache (before hard drive caching.) It does require a certain level of speed from your USB (or other) flash drive. Do a quick search on google for just the fastest USB flash drive you can get your hands on (women € ™ t worry they are cheap) and buy one.

To enable ReadyBoost, just plug in a fast flash drive, and autoplay should come up with a dialog stating that you can use it for readyboost. If you have disabled it, you can just go to the properties for the drive and select it under the readyboost tab. Easy as cake. It is no substitution for RAM, but one can get a several GB flash drive for very little. Some sites have stated that the improvements are not as much as MS says they are, but even a minor improvement for such a low investment makes this worth your while. Do find the best drive you can for random reads / writes (the drive speed is usually rated for sequential reads which wonâ € ™ t help you much).

     * What speed drive do I need? 2.5MB/sec throughput for 4K random reads and 1.75MB/sec throughput for 512K random writes.

     * What size drive do I need? 256MB to 4GB, where as best performance is gotten at around a 1:1 to 2:1 in flash to ram ratio. So really, you should never try this with a flash drive smaller than 1GB-2GB
 4. Tweaked Indexing Service

I personally woman € ™ t the new research, too. Although pigs a large amount of resources, though. If you completely out:

       * Go to My Computer, right-click the folder C: drive, go to the General tab and uncheck Index this drive to speed up the search, select Include subfolders and files.
       * You can use any additional areas of research, so you can quickly your search to certain areas.

Personally I think the indexing of the options in the control panel and menu items to start as a blessing, so let alone. Only to find items in the tree that women actually € ™ t want to be indexed (including documents).
5. While you are in this solution the rest of your search

Often it is for me to do research in text files, as a method for use in a PHP file, or perhaps something in a file java. Whatever the situation, Windows Vista has a very limited number of extensions scored for the full-text search, which gives rise to “no results” when we know there are some.

       * Open Control Panel and type of “indexing” in the search field (or you can do in the Start menu, but many people off).
       * Select Options for indexing ”
       * Select the Advanced button
       * Select “File Types” tab
       * On this list you’ll see a list of extensions. If you click on the majority of them, the bottom button from the index only properties or properties and index the contents of a file ‘
       * Frankly, index-only properties is fairly useless so most people use for research (which is to say, actually just a search by date).
       * Remove an image that you removed from the search. This can be done for a series of extensions that honestly, issued € ™ t want to know anyway. Is it really help your score.
       * Change button in the index of the properties and contents of a file “because these types of files included in the research (should be established for Word documents, and any other text-based search in the archives)

6. So the sidebar

On declares itself. Ita € ™ s a heavy and ugly. If you use it, great, if you are a woman € ™ t something desktop space. Setting the google. Or Yahoo.
7. Ombudsman has a use?

Yes, Windows Defender actually has a purpose!

       * Opens
       * Click on Tools
       * Click Explorer software
       * This will allow you to select groups of items, the default is to start programs. Now you see that oh, OpenOffice is fast, and you can just turn off.

The items on this list is very likely that the programs that run at 100% of the time that your computer is on, so if you can live without them, kill them.

8. Fine-tune their services

Well, this is a debatable. Many sites preach the service information to adjust the end of all institutions, and Vista has a lot of services (like 130). However, a good portion of them are configured for manual or default. Manual only started the service when the operating system thinks it needs to use this program. However, Vista has a lot of services set to Auto by default, which are not necessary for many people. Of course, which normally for sleeping, that does not use CPU, and whether the use of space, usually in paged to disk very quickly. But, regardless, it is reasonable to make fast, and gain some improvements.

Firstly, how to say what should be really worried. A new feature in Vista is the â € ~ Go to Service € ™ feature in Task Manager (or at least I’ve never noticed that before). Open Task Manager, Processes tab, right-click a particularly heavy and select a € ~ Go to Service (s) â € ™. This instead of the Services tab and select all services carried out under this process (which are usually multiple svchost.exe runs, many of the other only on a map service).

It also works the other way (select service, right click and go to trial) I have something to 75 servers working at the moment. Most of them are exactly zero for use. I do not have a printer, but print queue is implemented and the use of a huge range of my 1 MB RAM at the time. There are more examples, but even if you get 20 of these, it’s your time worth? Well, yes and no. As I said, many of them are already paged, so really scenario € ™ t that affect their system € ™ s memory. Do not include overhead costs, because the developer has yet to master, but I can not for the life of my record the way it does in Windows.

In general, perhaps minimal, but if you go for every ounce of change Ness, give it a chance. IA € ™ d recommend looking Tips Speedy Vista registration pages or files, so you can keep a copy of the standard services around when / if the current rail systems and the need to return to the default page.
9. How can you find out what the area of improving â € “tweaked their programs

Well, youâ € ™ s received the operating system to some extent, what € ™ s next? Well, guess where the bottlenecks still! There € ™ s probably a kind of software on the computer and only kills the implementation (or 6.7 of them). Mrs. € ™ t really blame MS yet. But fortunately for Windows Vista has a simple device, including to help identify and resolve the problem quickly.

       * Open Task Manager (many ways to achieve, the easier it is CTRL + ALT + DELETE and select Start Task Manager)
       * Click the Performance tab
       * Click Monitor Resource
       * Expansion of the disc and order by a read or write the column.

You can also take a look at the CPU, memory and network usage in the same way. Now you have probably noticed that your virus scanner is the use of resources 20x Aero, as it insists on the exploration of its RAM all the time, and cursed scans every file that read, write or run. But what can you do? Looking for a few programs that are coveted, or run when they have no reason to take action (for example, iTunes has a couple of installation canceled services that run constantly. Why? IA € ™ ve no idea to which services 2.3 and multiple threads just looking for himself could connect your iPod, because the functionality is already included in Windows). Office also has a preloader € ~ â € ™ fast start services (such as OpenOffice) to make sure things work € ~ â € ™ bettered for you. Even though you get super it should do so automatically, without the need for additional memory.
10. In fact, nobody, but tune …

Ok, # 10 ISNA € ™ t really a speed of the story, but Italian € ™ s € ™ IA something I’ve always found annoying on many operating systems. Many of us have 2 LCD monitors, and oh € ™ t would be nice to be able to make various sources of both? There are programs here do, but here € ™ sa way to do this only within the windows.

       * Right-click the background and select Customize.
       * Click on the desktop background
       * Choose a background image that is at least as wide as the whole of the resolution of the two monitors (or the scale of the image until it is large enough, what you get .. tiling to be an adjustment in order to let your photo editor for your choice.
       * Select the image tile positioning option as shown below. This is the only option for the background image for multiple monitors
