I'm less than a newbie. I have no radio or experience and am wondering what
the ins and outs are. The idea of conversing with people all over the place sounds very interested. Can someone give me some feedback on how it works, what kind of range there is, general ideas about the $$ involved, and a few things I'm too ignorant to ask? I know there is a broad range but I have to start somewhere. Thanks Eph |

Here is a good place to begin looking: http://www.arrl.org/ Steve Holland, MI Drake R7, R8 and R8B http://www.iserv.net/~n8kdv/dxpage.htm |

If the idea of "listening" to people all over the world is what you are
looking for, you are in the right place, well sorta, if you can get by all the off topic posts............. "Ephraim" wrote in message ... I'm less than a newbie.

I know there is a broad range but I have to start somewhere. I think what you're looking for is "amateur" or "ham" radio. The suggestion to start at http://www.arrl.org is a good one. In theory this newsgroup is for those listening to international broadcasts (and not talking back) but there's a lot of overlap. Amateur radio requires a license. I'm making the educated guess from your post's headers that you're in the USA. Here, a license that allows operation on the international HF frequencies requires passing a simple written test and a 5wpm (VERY slow!) Morse Code exam. The Morse requirement is likely to be deleted in the next two years (or sooner), though there are real advantages to knowing Morse even if it's not required by the government. Already, you can obtain a "Technician Class" license without passing a Morse exam. This allows operation on VHF and UHF frequencies. On these frequencies communications throughout your metropolitan area are possible; sporadic nationwide communications are possible on the 50MHz band. (and potentially worldwide but you'll have to wait for an 11-year atmospheric cycle to come around) The licensing exams are given by local radio clubs, often at annual hamfests. The arrl.org site has lists of local clubs and examination schedules, as well as outlines of the written tests. There is no fee payable to the FCC for a ham license, but there is a modest ($10 IIRC) examination fee. Range is potentially worldwide. That is somewhat dependent on atmospheric conditions and the quality/size of antenna you're able to install. Contacts throughout North America are very possible with simple antennas, poor conditions, and low power. A basic ham station consists of a "transciever", a power supply for that transciever, a microphone (and Morse key?), an antenna, and "leadin" cable to connect the antenna to the transciever. Good quality transcievers can be purchased new for as little as about $700; used gear is of course cheaper. A decent power supply will run about $150, or you can use a car battery if you have a safe place to store it and a safe way to charge it. A microphone is usually included with the transceiver. A wire antenna can be home-made from parts available in the wiring department of Home Depot for less than $50. You'll have to get the leadin cable elsewhere though (probably the same place you buy a transceiver), $50 should probably cover that too. So I'd say just shy of $1,000 to get started with new gear. You will need some space for the antenna. How much space determines how many of the frequency bands available to hams you're able to efficiently use. A 260-foot antenna may be necessary to use the very lowest-frequency band available, while 20 feet is plenty for the highest band. There are ways of getting on with something smaller (many hams operate from their cars) though they're somewhat more expensive and less efficient. -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com |

Eph:
Short wave listening (SWL) lets you listen on frequencies from other countries. Some of the content is beamed toward specific audiences on high power shortwave stations. To receive this, a decent "general coverage" receiver is usually in order, along with some sort of external antenna. You can get started with a portable and the supplied whip antenna, but they tend to receive only the strongest stations due to limitations of the antenna. There are numerous web sites that detail listening frequencies and times for specific broadcasts, or you can just tune the dial to se what's out there at a given time. Doing a Google search for "short wave listening" or "short wave frequencies" should result in some places to start reading. If you are interested in knowing what you are listening to, you should probably get a radio with digital frequency display. For portable, carry around operation, I use a Sangean ATS-909 (same as a Radio Shack DX-398). If you want to talk, you will need to become a general class ham (Amateur Radio Operator) (if you are in the US, other countries have similar radio licensing requirements), and acquire a transceiver. The General Class license will allow you to transmit on specific bands to communicate with other hams around the world. Antennas are generally more critical for transmitting, either cut to a specific band or built in a manner to cover multiple bands. You can talk around the world with 5 or 10 watts output if the conditions are right. Most Amateur Radios have variable output to 100 watts, with a few available with higher output. For those that think they have to have the strongest signal out there, Linear amplifiers allow increasing the power output, but generally, they are not needed. You can purchase a new bare bones transceiver starting at about $600 or so, or pick up a very good used one from $300 or so. Many Ham Transceivers also have "general coverage" receivers and can receive from below the US AM radio band to 30Mhz, the limit of the standard HF ham bands. US Hams work 10m 12m 15m 20m 40m 80m and 160m bands. (10m is 10 meters). If you find you are interested in becoming a Ham, you may want to purchase a transceiver to use as a SWL receiver, so you don't have to buy another radio down the road. So long as you don't transmit on it until you get your license, it is legal to own. One transceiver I own that is good is the Icom-751 or Icom 751a. Both versions are easy to use, with sensitive general coverage receivers and reasonable filtering built in. They are often seen on eBay selling between $350 and $550. To really "do it right" you will also need a good antenna (which could be as simple as a wire strung through the trees), an antenna tuner, and SWR/Power meter. Many transceivers (like the 751) have the metering built in, but I prefer an external meter. If you were using the transceiver as an SWL radio, you could just unplug the microphone, hook the radio up to a power supply and connect an antenna and you are ready to listen... As an Amateur Extra class ham, I began with SWL, and have owned a bunch of different radios over the years. Currently I operate with an Icom 746Pro into an x-9 beam on a 48 foot tower, and when mobile I use a Yaesu FT-857 into an Atas-120 antenna mounted at the back edge of the cab of my pickup. In the mobile rig, I listen to SWL stations as much as I operate as a ham. Due to the noise of the truck ignition and computer systems, the radio is not nearly a sensitive under way as when I'm sitting still, and the Atas-120 antenna is a significant compromise compared to a half wave dipole or beam antenna like I use on the home station. Good luck --Rick AH7H Ephraim wrote: I'm less than a newbie. I have no radio or experience and am wondering what the ins and outs are.

Thank you very much. Learn a bit every day
