The YAESU FT-991 transceiver is displayed at the Ham Fair Tokyo in 2014.
Leg: 44 feet Leg: 44 feet
Stub: 9 feet 6 inches (450 Ohm Ladder Line)
Coax to transmitter (50 Ohm any length)
It’s Time To Put Up The 20 Meter EDZ And Add 3-dB Gain Over Your Dipole!
This 20 Meter Extended Double Zepp (EDZ) antenna should produce a 3-dB over the average half-wave dipole. This is significant enough to try it. An automatic tuner should tune this antenna with no problem. If one should feel it necessary, a 1:1 Balun would do the job.
Basically, the Extended Double Zepp Antenna is a pair of 5/8 wave elements. The total length is approximately 1.25 wavelengths long.
For different bands and different lengths, here is a chart that is helpful. The figures are not exact with this example, but they are close enough for ham radio.
(A) One element length is:
One leg is… 598.5/F (MHz)
(B) Stub length is… 142/F (MHz)
The 12 Meter EDZ Antenna
The same principals apply for the 12 Meter EDZ. For each leg, use 25 feet 3 inches. For the stub, use 5 feet 5 inches.

I have a 32-inch Samsung flat screen TV that plays well and has great color in the picture. The speakers in the television are adequate but I want a little more audio. I just like the big sound, something more of a studio quality. This is my first LED TV so I’m getting used to the connections in the back. I’m trying to find a simple way to get better audio from this TV.
I ordered a Y adapter. It’s a TV 3.5mm to RCA F/M cable. I was intending to hook this adapter to my mixer, but I didn’t observe if there was an audio out for this cable. After I had ordered the small adapter, I then discovered that there was no audio out. The Y adapter didn’t work. Oh well. It was a cheap price.
I had also ordered 3.5mm male to male cable (StarTech.com MU15MMS 15 feet Slim 3.5mm Stereo Audio Cable – M/M), about 15 feet of it. I experimented to see if this 3.5mm would hook up to the place designed for a digital cable, which is the correct cable.
I used an adapter (LE Quality Headphone Adapter Stereo Gold Plug 1/4-Inch (6.3mm) Male to 1/8-Inch (3.5mm) Female by efuture) to go from the 3.5mm jack to the 1/4 in. jack that fits into my mixer.
Guess what? It worked! I don’t think it is true stereo, yet the audio quality is not bad at all. This will suffice until I can obtain the proper cable (AmazonBasics Digital Optical Audio Toslink Cable, 6 Feet), a stereo receiver, and some nice shelf speakers.
I’m running the cable to a Behringer 802 mixing board, which gives me the opportunity for some modest equalizing, and the convenience of the little mixer is the sweet part. And audiophiles like knobs to play with.
The speakers I recently purchased sound great, so I am trying to make use of my small, casual studio. It’s not that expensive to install a nice sounding system. Nothing elaborate here, but way better than the standard factory quality. I am satisfied with the sound.
I know. Who watches television anyway?
I didn’t have the big audio with my Google Chromecast, while watching YouTube videos. The audio was from the television speakers and now it is channeled through my mixer and speakers.

Solar cycle 24 began on January 4, 2008 and so far has been the smallest sunspot cycle since 1904. Solar cycle 24 “is on track to be the Solar Cycle with the lowest recorded sunspot activity since accurate records began in 1750.”
Solar cycles supposedly have a duration of about 11 years.
“In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Since it is not limited by the curvature of the Earth, skywave propagation can be used to communicate beyond the horizon, at intercontinental distances. It is mostly used in the shortwave frequency bands.”
Most long-distance HF radio communication—between 3 and 30 MHz—is a result of skywave propagation.
“Since the early 1920s amateur radio operators (or “hams”), limited to lower transmitter power than broadcast stations, have taken advantage of skywave for long distance (or “DX”) communication.”
If you’re a mild audiophile like me, then you’re looking for nirvana with some affordable speakers that fill the room up. I wanted a decent sound system to quench my audiophile thirst, and I wanted to afford to eat my lunch at the same time. I accomplished this goal when I purchased the Logitech Z313 Speaker System. For around $40 nirvana was found.
It was plug and play right out of the box. I think I had to plug the two satellite speakers into the outlet in the back of the subwoofer, which also plugs into the electrical outlet. Turn on some FM music and nirvana was there. Like magic the 25 watts of sound filled the room and I was overjoyed.
Without shelling out some $200 for the big shelf speakers, I don’t think it gets any better than the Logitech Z313 Speaker System. The speakers sound good and the subwoofer adds some big bass to the song. The bass is not overwhelming and it sure beats what you get out of those cheap little computer speakers, the ones that can’t handle any bass.
I am channeling my speakers through a small mixer board, the Behringer 802 to be specific. This allows me to add or subtract some lows and highs. It has knobs that help to control the volume and provide opportunity for some modest mixing. This little mixer makes it fun for graphic equalization. I plan to upgrade to a bigger mixer soon.
In conclusion, I am happy with this system. Anything less and I would’ve been very disappointed. These speakers sound very nice and I am picky about my audio.
One feature that I like is the volume switch that includes a headphone hookup. It makes life easier having this switch for armchair availability, even though I have volume control on my mixer. And the headphone hookup within reach is an added bonus.
I hope to enjoy these speakers for years to come and I would highly recommend them to anyone. I feel like I got my money’s worth this time.
Relax. You can run Windows XP forever, even if you have upgraded your OS software, and that includes the Linux crowd. Believe it or not, some programs still run on Windows XP. No problem. You can run Windows XP applications on Windows 7 or Windows 8 PCs or even Linux machines. Is there software that allows you to use XP on a newer operating system?
Yes. Here it is! It’s called VMWareplayer and it does what it claims to do.
From the site:
Run Windows XP applications on Windows 7 or Windows 8 PCs or even Linux machines. With Unity mode, copy-and-paste, drag-and-drop, and networking and printing that require no additional setup, Windows XP and applications developed to run on Windows XP will run seamlessly on modern hardware.
Make a note that you will need a copy of Windows XP if you happen to find one, and the product key is necessary to process it.
If you download this software and follow procedure, you will be able to feel the nostalgic touch of yesterday. Actually, many users prefer Windows XP and are adamant about using it.
It’s surprising that some software will function more properly with XP. Old habits are hard to break. We live in a virtual world now so no problem. See you in the matrix.
Is it possible to text or chat off-the-grid? The short answer is yes. Open Garden has launched FireChat for iOS. The FireChat app will work with Apple products and you do not need an internet connection in order for it to work. Using the Apple framework, the app utilizes Bluetooth or WiFi.
You don’t even need a password. It’s good news mostly but caution is recommended. Here’s the kicker. Say you’re at an event or on location somewhere, and you woul dlike to chat with friends. No problem.
The downside is that everybody that has the app can see what you’re texting. If you are in a remote location then it’s no problem. The TUAW site says that the range is 30 feet.
But you can chat or send photos anonymously. So it’s not a problem really.
Open Garden supposedly has an Android app also.
• Instantly message anyone around you on iPhone, iPad or iPod touch,
• Chat and share photos with one person or with a group,
• See what people are talking about everywhere, or create conversations that only people near you can join,
• Works even without any 3G, 4G or Wi-Fi connection,
* The Nearby mode works best within 30 feet of your location,
• Easy: no Facebook or email login, no password to remember,
• Use it at home or when travelling anywhere in the world,
• No significant impact on battery consumption,
• FireChat is designed for iOS 7.
In the United States, there are two things that do not go together; water and electricity. Well, water is heated through an electric water heater, but this is not quite the same as an electric bath. In Japan, electric baths (denkiburo) are available for the taking. Bathe at your own risk.
I’m not knocking it, just saying that it seems a bit dangerous. The Japanese are some wonderful people. Whatever works for them, I’m all for it.
Stay away if you have a pacemaker inside of you. Stay clear if you have a heart condition.
Who could imagine soaking in the tub with electric current sending tingling sensations up the back. Nup, I don’t think so. I just can’t see it happening. With the accident rates, bad luck, and rivals wishing to up the voltage, this would not fit into mainstream American culture. Maybe the psycho slash movies. That’s a thought.
If you live in the United States or plan to visit, you might take a look at Bathhouse Row, located in the city of Hot Springs, Arkansas. Good luck!
If the poorly designed lamp goes bad, all it not lost my friend. Unplug the lamp first. The lampshade has plastic material that will easily peel off if you try. Try using a pair of hand pruners and maybe a pair of needle-nosed pliars. You’ll find some wire in there. Believe it or not, you have a police scanner antenna in your hands! The lampshade will serve as an antenna.
Some lampshades have an almost perfect discone shape, while others have a loop shape. Either will work fine. So you lost a cheap lamp because of a cheap switch, but now you have a scanner antenna that works fabulous. Discone or loop, we’ll take it as we get it.
This isn’t all of the good news though. The lamp that went bad will have a cord that plugged into the electric socket. Again, make sure the cord is unplugged from the socket. Then, cut that cord from the the lamp.
So there you have it. One bad lamp makes two scanner antennas.
I now need a new lamp. Oh well.
Setting up Chromecast is a simple process for the most part, and the reward is worth it. Just follow along with my guide and you’ll get your Chromecast going. If you have trouble with setup you can leave a comment and I will do what I can to help.
Note: Google will only let you use Chromecast with its Chrome browser, so make sure that you have it installed on your computer before you begin. If not, you can download it from google.com/chrome.
It’s also necessary that your computer has a wireless card or that it is connected to a wireless router interface. If not you can purchase the Edimax EW-7811Un 150 Mbps Wireless 11n Nano Size USB Adapter to make your computer wireless.
To begin, get your Chromecast and plug it into your TV’s HDMI port. If your TV’s HDMI ports are cramped together, then try using the HDMI extension cable provided with the box.
The Chromecast will then need to be powered. Plug in either the AC adapter or the USB cable to the dongle. The USB cable is the easiest route, providing that you have a USB port on your TV.
After you have it all powered up, get your remote and switch the input to the corresponding HDMI port.
If everything goes well, you will see the Chromecast startup screen.
Go to google.com/chromecast/setup to download the setup app for your Mac or PC. Alternatively, you can install the app on your iOS or Android device. Once you have downloaded the app, launch it.
There will be a code and you will need to check to see if it matches with the one on the TV. If so, press on the button that reads “That’s my code”.
You will be prompted to choose a Wi-Fi network and enter the password. Change the name of the Chromecast to whatever you like and continue.
Note: Some users have experienced trouble with getting their Chromecast to connect to the Wi-Fi network successfully. You can see a list of Chromecast supported routers here. If you are still having trouble connecting, visit Google’s troubleshooter.
If all goes well you will see “Ready to cast” on your TV. This is your cue.
You will need to install the Google Cast extension from the Chrome Web Store.
After it installs you will notice a button for Google Cast in the upper-right corner of your browser.
Now for the moment you’ve been waiting for.
Click on the Google Cast extension that you just installed and cast the tab to your Chromecast. Chrome will cast itself to the big screen.
Some services, like YouTube and Netflix, will have a seperate button on the video you will click to cast to Chromecast. After the video is casted you can still operate in the browser as usual without it effecting the video playback on your TV.
On mobile devices you will find a Chromecast button in supported apps such as YouTube, Netflix, Hulu, Pandora, Crackle, and Google Play.
The Chromecast-supported apps are always growing. For a full updated list go here.
And with that, your dumbfounded TV suddenly became smart.
