6 Meters DX from the KATU Channel 2 analog tower

On June 13, 2009, a select group of hams assembled at the recently deactivated KATU Channel 2 analog TV tower to run 6 meters SSB from the tower. Using a Kewnood DS-60 and a 500-watt amp, we were able to work stations from Saskatoon, SK to Tijuana, Mexico.

Power Acoustik Amp, Kenwood Subs & Decibel Meter

On my last video my camera died right before I got to show you what my system sounded like. It eats batterys in like 5 mins. Like I said I'm not rich so my subs aren't hitting 140 dbs or anything but not bad for cheap 8 gauge power wire hooked up like crap. Thanks for watching. I'm getting a new camera in a few weeks so my videos will be better sounding. Please rate bad or good whatever you think. SUBSCRIBE if ya wanna see more videos maybe showing you some cheap ideas. :) The System (1) Power Acoustik Sapphire MRP 2400 - Class D Monoblock Amplifier (2) 12 inch Kenwood Tsunami Subs - 400 Watts @ 4 ohms (1) Old School Kenwood Head Unit (2) Infinity Kappa Mids (rear deck) 330W peak power (110W RMS) Cheap 8 gauge power and ground wire (Stupid for this amp)

Composter Accessories

!±8± Composter Accessories

When many people think of composting, they just think of tossing food scraps in a bin and letting them decompose. But the process can be so much more complicated than that. Composting enthusiasts often use lots of different tools and accessories to take some of the work out of the process.

A compost accessory that has become very popular is the scraps container. This is a nice-looking canister with a handle that goes in your kitchen. They can be gotten in wood and metal, among other materials. This is a great place to stash your kitchen scraps each day so they are hidden from site but easily accessible.

If you are looking for something to speed up the composting process, you can buy accessories such as accelerator. This liquid is formulated to make things break down faster and more effectively. You can also buy things like a "leaf muncher" that will crunch of leaves and other soft yard waste to make it better for adding to compost piles.

During composting, you can check the moisture and Ph levels in the bin with a meter that reads both. This makes it easy to keep the right amount of water in the bin. This will also help you keep your compost from becoming too acidic for your plants.

For applying finished compost, you can get a compost spreader. This is a great way to get your compost wherever you need it quickly and easily. There are a couple different styles, so you can pick the one you like best.

There is really no end to the list of accessories you can get to help your composting. Compost turners, books, bin screens, and other items can be found in many stores. By checking out some of these, composting will become an even easier and more rewarding process.

Advantages of CNC Machining 5 Axis For the Inventor

!±8± Advantages of CNC Machining 5 Axis For the Inventor

One of the hardest and one of the most important decisions an inventor or designer can make is how to replicate and produce their creations. For many, it seems that with the wide array of choices in countries and companies, the options just seem too intimidating and it can end in the inventor making a costly mistake, which therefore makes it the most important and hardest decision. Also, with the new advances in Manufacturing and Metalworking Technology, such as the CNC machinating 5 axis, the options have now doubled for inventors and designers.

Opposed to seeing it for the positive that it is; it is viewed as a negative, but it is quite the contrary. For instance, the CNC machining 5 axis systems offer many new benefits for the inventor and the designer alike. A few examples that are offered by the CNC machining 5 axis systems is the fact that it has the capability to mold small complex steel shapes if required, which is difficult such as a landing gear strut for a plane.

If you only want to make say 40 parts then the CNC machining 5 axis systems are perfect due to the fact that it is able to adequately produce in large quantities. All too often the price of something with very premium service is sacrificed in comparison to another cheaper yet less effective machine. Quality vs. Quantity is a common problem, but with the CNC machining 5 axis systems, there is no such sacrifice necessary. The CNC machining 5 axis systems, in all actuality, cut down on costs, and are not just as precise but somewhat more accurate than the other systems.

However, in America, there is only a hand full of companies that can provide this service, and this can be in itself much more expensive. Therefore, the best option would be to look to Chinese Manufacturing. Due to manufacturing being a major industry in China, the availability as well as the abundance of companies, leads to much cheaper options than the American Companies utilizing the CNC machining 5 axis systems, with no loss in quality.

As a final result, a tremendous amount will be saved in terms of labor costs, and shipping, as this is handled by the representative. This is the true benefit of using the CNC machining 5 axis systems as well as Chinese manufacturing services for your inventions and designs.

Digital Multimeters - A Look at Essential Parts and Basic Functions

!±8± Digital Multimeters - A Look at Essential Parts and Basic Functions

A digital multimeter is a critical and indispensable component of the electrical technician's toolbox. Companies such as Fluke, Mastech, Tektronix, and Extech to name a few manufacture popular brands of these devices.

These electrical measuring tools range in price from as little as for the most basic models to around 00 for top of the line units. Regardless of the make or cost, digital multimeters share many of the same functions. This article provides a brief overview of the essential parts and basic function of the typical multimeter.

Display

A digital multimeter generally has a large and intuitive display that is simple to use and easy to read. Most displays have a four digit display, with the first being a 0 or 1, with a +/- indicator. Some units may also have additional displays, such as an AC/DC readout.

Connections

All digital multimeters have two connections for the probe; some models may have three, four or more. Connectors are attached to leads that are flexible, well insulated, and terminate with connectors that are appropriate for the particular meter.

The main connectors on these devices include:

1. Common connector, which is used for all measurements. The negative (black) lead probe is usually attached to the common connection.

2. Voltage, ohms, and frequency connector. This connector is used for most types of measurements. This connector accepts the red probe.

3. Amperage connector. Used for measuring amps (current), this connector also takes the red probe.

The Main Switch

Every electrical measuring device needs a switch to turn the device on and off. Digital Multimeters have one main switch used for that purpose. The main switch is normally a single rotary switch that is used to turn on the power and select the type of measurement that will be made.

Other Features

In addition to the above standard parts of the typical digital multimeter, there may be many other features on specific models made by different companies, such as additional displays and controls. Some multimeters include functions for specialized applications, such as a probe for measuring temperature, scales for measurement of decibels, capacitance, transistor gain, motor windings resistance, wiring continuity, insulation tests, and so forth.

Most manufacturers keep devices fairly simple however, and offer a standard layout that is common to all their products. This standard layout has been the norm for multimeters for many years and will likely be common for the foreseeable future - barring any new revolutionary design.

In conclusion, it is probably safe to say that whatever form these essential electrical measuring devices take in the time to come, they are certain to be found in every electrician's tool kit for many years to come.
