The beauty of it is - they want you to succeed!
Think I will pick it up the next time I'm out by a Borders or other bookstore....what kind of start up costs would I be looking at to begin.....if I pass:)

I would say between 200-400$ for a good hand held radio. The Yaesu hand helds seem to be the most popular. Kenwood is also a good brand.

Here is a look at some of the models:

You can usually get some good deals at hamfests, other ham groups in your area. http://www.qrz.com has a forum which lists hamfests in the various areas.

Once you have an idea of what you want, you can check deals out on eBay.

http://www.gigaparts.com also has used radios available.

This is a good link for ham forums. ;)

The handhelds are the cheapest way to get into ham radio, as you do not need to set up a hamshack with transceiver, power supply, antennas, etc...

Hey, Turtle! Keep on studying for that General License. It's easier if you get right on it.

I took the Tech test in February 2003, and then pushed right on for the General written exam 2 months later - then took the Morse Code test to qualify for the General Lic in May of that same year. That way, I didn't have to keep re-learning it all over again.

I stopped at General w/code test. Now, you do not need Code for the General. Glad I had to pass, at least, the 5 wpm Morse Code. It was very intense and a real triumph for me to pass it! Don't think I could have ever gotten to the 13 wpm code test they had for several years before that! And the even stricter codes tests before that.

It is so much easier to get a General License now.

I may check out Echo Link. ;)

The Comet UHV-6 is Comet's 3rd generation HF - UHF mobile antenna and it's the best! Without the HF coils attached, the UHV-6 is a tribander for 6M/2M/70cm. The top of the element has a threaded socket for attaching either the 40M, 15M or 10M coil that comes with it making the UHV-6 a quad-band antenna! Want more HF bands?? Simply add an additional 1 or 2 HF coils horizontally using the threaded sockets in the ring around the top of the element! Purchase the optional elements for 80 meters (L-3.5), 20 meters (L-14) or 17 meters (L-18) as shown below. Each HF coil tunes independently to the part of the band you want to operate.
2:1 VSWR bandwidth is approximately:
40M 23 kHz
20M 55 kHz
17M 75 kHz
15M 100 kHz
10M 400 kHz

Unlike the screwdriver antennas that are expensive and difficult to mount, the UHV-6 is easy. If you have an existing antenna on your vehicle that has a sturdy mount with an SO-239 connector, simply take it off and put the UHV-6 on! You are on the air! AND, the UHV-6 is a ½ wave on 2M: 2.15dBi gain over a ¼ wave and it's 2 5/8 waves in phase on 70cm: 5.5dBi gain.

The fold-over hinge on the UHV-6 is a strong hinge protected by a threaded collar. Unscrew the collar and lift it up to expose the hinge, very convenient when entering garages, parking structures, drive-thru's, etc.
then i got the tri-pod that goes up 6ft and the telescope pole that goes up 33 feet. I aksed the store if i could mount the antenna UVH-6 on there and he said yes with a gooooood. ground. with radio it was all under $1200.00.

listening to the 7240 net meeting now on short wave. barely comming in but got just enough. back to the books......lolo

Radio Chip that Mimics Human Ear

Post by Linnea » 06-04-2009 03:33 AM

June 4th, 2009 - 3:18 pm ICT by IANS

Washington, June 4 (IANS) Indian Americans have engineered a fast, ultra-broadband, low-power radio chip mimicking the inner ear, or cochlea, one that could enable wireless devices to receive cell phone, Internet, radio and TV signals.

Rahul Sarpeshkar, MIT associate professor of electrical engineering and his graduate student, Soumyajit Mandal, designed the chip. The chip is faster than any human-designed radio-frequency (RF) spectrum analyzer and also operates at a lower power.

Mandal graduated from the Indian Institute of Technology, Kharagpur, India in June 2002. He completed his MSc in 2004 at MIT and is currently working on his Ph.D.

“The cochlea quickly gets the big picture of what’s going on in the sound spectrum,” said Sarpeshkar. “The more I started to look at the ear, the more I realized it’s like a super-radio with 3,500 parallel channels.”

They have also filed for a patent to incorporate the RF cochlea in a universal or software radio architecture that is designed to efficiently process a broad spectrum of signals including cellular phones, wireless Internet, FM, and other signals.

The RF cochlea mimics the structure and function of the biological cochlea, which uses fluid mechanics, piezo-electrics and neural signal processing to convert sound waves into electrical signals that are sent to the brain.

The RF or radio frequency cochlea can perceive a 100-fold range of frequencies — in humans, from 100 to 10,000 Hz.

Sarpeshkar used the same design principles in his cochlea to create a device that can perceive signals at million-fold higher frequencies, which includes radio signals for most commercial wireless applications.

The device demonstrates what can happen when researchers take inspiration from fields outside their own, says Sarpeshkar, according to a MIT release.

Their research is slated for publication in the forthcoming edition of the IEEE Journal of Solid-State Circuits.

Yes! The world is chock full of analogies that can be exploited in what seems to be unlikely ways. Cross comparisons of ideas from different fields might raise a few eyebrows, but they can sometimes come in very handy.;)

2009 Sees Surge of New Amateur Radio Licensees

Post by Linnea » 01-07-2010 04:32 AM

from ARRL dot org:

This past year was a banner year for new Amateur Radio licensees. According to ARRL VEC Manager Maria Somma, AB1FM, the FCC issued more than 30,000 new ham radio licenses. "In 2009, the demand for Amateur Radio exam sessions remained elevated and is still running at a higher rate than before the FCC's restructuring of the license requirements in 2007," Somma said. "This high level of exam session activity has produced an elevated influx of new applications, far outpacing recent years."

A total of 30,144 new licenses were granted in 2009, an increase of almost 7.5 percent from 2008. In 2005, 16,368 new hams joined Amateur Radio's ranks; just five years later, that number had increased by almost 14,000 -- a whopping 84 percent! The ARRL VEC is one of 14 VECs who administer Amateur Radio license exams.

"When looking at the statistics over the last 10 years, these are some the highest numbers we've seen," Somma explained. "Additionally, our total number of licensees across all three classes has grown each year." Currently there are 682,500 licensed Amateur Radio operators in the US, an almost 3 percent rise over 2008. In 2008, there were 663,500 licensed amateurs; there were 655,800 in 2007. Broken down by license class, at the end of 2009 there were 17,084 Novices, 334,245 Technicians, 150,970 Generals, 60,795 Advanced and 119,403 Amateur Extra licensees.

"The ARRL VEC has been busy meeting the needs of the Amateur Radio community by helping people to become radio amateurs or upgrade their existing licenses," Somma said. "In 2009, ARRL VEs administered 44,595 exam elements at 6369 ARRL VEC-sponsored exam sessions. The number of amateurs who want to be Volunteer Examiners and who want to teach Amateur Radio classes is also going up -- we've seen a spike in the number of applications from General and Extra class radio amateurs who want to give back to their community by serving as ARRL examiners and instructors."

Somma applauded all the volunteers whose "hard work and contribution of countless hours of time helps to ensure the future of Amateur Radio. The ARRL VEC thanks our 32,411 VEs from around the world whose dedication and service helped to contribute to the success of Amateur Radio. I am delighted by these important achievements. 2009 was a very good year for Amateur Radio and I am excited by the promise of 2010."

does anyone out there know where i can get the rules governing citizen band radio's. I've looked everywhere and on FCC.gov that was to scary. lots of good people here in quartzsite use the CB to communicate back on forth. generally we stay on channel 30. but some of the guys go to 19 and talk to truckers. like my better have and i like talking to truckers. now you know this is cb and there are a few big radios out there. we tease the truckers and they tease us. i should say (not me because I'm a Ham and i do not want to go down that road. I'll talk no teasing)

but we have one CB shop out there by the name of hard drive. Mark Sherman is his name. he has taken over channel 19 for advertising his business. he tweak and peeks radios.

he said he can advertise all he wants. he offers his services and his products. now it is CB so i just let it go in one ear out there other but now he chasing others off the channel. So now if anyone gets on there he bullies them off by calling them names, and telling them this is an emergencies frequency for travelers communication and truckers only (by the way by FCC rules ...its 9).

anyway i just need the rules governing CBs. i have rules at home but didn't bring them.

Hiya Turtle!

Post by Linnea » 03-06-2010 07:50 PM

Here are CB rules:

FCC Rules for using the CB Radio

RULE 1 - Descriptions -
The Citizens Band Radio Service (CB) is a private, two-way, short-distance voice communications service for personal or business activities. The CB Radio Service may also be used for voice paging.

You must comply with these rules when you operate a station in the CB Service from:
{1} Within or over the territorial limits of places where radio services are regulated by the FCC.
{2} Aboard any vessel or aircraft registered in the United States
or {3} Aboard any unregistered vessel or aircraft owned or operated by a United States citizen or company.

Your CB must comply with Part 95/Subpart E [Technical Rules].

Where the rules use the word "you", "you" means a person operating a CB station. Where the rules use the word "person" the rules are concerned with an individual, a corporation, a partnership, an association, a joint stock company, a trust, a state, territorial or local government unit, or other legal entity. Where the rules use the term "CB station", that means a radio station transmitting in the CB Radio Service.

RULE 3 - Eligibility To Use CB -
You are authorized to operate a CB station unless:
{A} You are a foreign government, a representative of a foreign government, or a federal government agency.
{B} The FCC has issued a cease and desist order to you, and the order is still in effect.

{C} You must, at all times and on ALL channels, give priority to emergency communication messages concerning the immediate safety of life or the immediate protection of property.
{D} You may use ANY channel for emergency communications or for traveler assistance.
{E} You must share each channel with other users.
{F} The FCC will not assign any channel for the private or exclusive use of any particular CB station or group of stations.
{G} The FCC will not assign any channel for the private or exclusive use of CB stations transmitting single sideband or AM.

RULE 8 - Antenna Height -
{A} "Antenna" means the radiating system (for transmitting, receiving or both) and the structure holding it up (tower, pole or mast). It also means everything else attached to the radiating system and the structure.
{B} If your antenna is mounted on a hand-held portable unit, none of the following limitations apply;
{C} If your antenna is installed at a fixed location (whether receiving, transmitting or both) it must comply with EITHER one of the following:
[1] The highest point must not be more than 20 feet (6.10 meters) higher than the highest point of the building or tree on which it is mounted;
[2] The highest point must not be more than 60 feet (18.3 meters) above the ground.
{D} If your CB station is located near an airport, and if your antenna structure is more than 20 feet (6.10 meters) high, you may have to obey additional restrictions. The highest point of your antenna must not exceed 39.37 inches (1 meter) above the airport elevation for every 109.36 yards (100 meters, 1 hectometer) of distance from the nearest point of the nearest airport runway. Differences in ground elevation between your antenna and the airport runway may complicate this formula. If your CB station is near an airport, you may contact the nearest FCC field office for a worksheet to help you figure the maximum allowable height for your antenna.
WARNING: Installation and removal of CB station antennas near power lines is dangerous.
For your safety follow the installation directions included with your antenna.

RULE 9 - Equipment -
{A} You must use an FCC type accepted CB transmitter at your CB station. You can identify an FCC type accepted transmitter by the 'type acceptance' label placed on it by the manufacturer. You may examine a list of type accepted equipment at any FCC Field Office or at FCC Headquarters. Use of a transmitter which is not FCC type accepted voids your authority to operate the station.
{B} You must not make, or have made, any internal modifications to a type accepted CB transmitter. <*read Rule 25> Any internal modification to a type accepted CB transmitter cancels the type acceptance, and use of such a transmitter voids your authority to operate the station.

RULE 10 - Power Output -
{A} Your CB station transmitter power output must not exceed the following values under any conditions:
AM [Amplitude Modulation] - 4 watts carrier power [CP]
SSB [Single Side-Band] - 12 watts peak envelope power [PEP]
{B} If you need more information about the power rule, see Part 95/Subpart E.
{C} Use of a transmitter which has carrier [CP] or peak envelope power [PEP] in excess of that authorized voids your authority to operate the station.

RULE 11 - Linear Amplifiers -
{A} You may not attach the following items (power amplifiers) to your type accepted CB transmitter in any way:
[1] External radio frequency [RF] power amplifiers, also called linear amplifiers, or linears;
[2] Any other devices which, when used with a radio transmitter as a signal source, are capable of amplifying the signal. {B} There are no exceptions to this rule and use of a power amplifier voids your authority to operate the station.
{C} The FCC will presume you have used a linear or other external [RF] power amplifier if-
[1] It is in your possession or on your premises;
[2] There is OTHER EVIDENCE that you have operated your CB station with more power than allowed by CB Rule 10.
{D} Paragraph C above in this section does not apply if you hold a license in another radio service (HAM, etc.) which allows you to operate an external RF power amplifier.

RULE 12 - Permitted Communications -
{A} You may use your CB station to transmit two-way plain language communications. Two-way plain language communications are communications without codes or coded messages. Operating signals such as "ten codes" (10-4, etc.) are not considered codes or coded messages. You may transmit two-way plain language communications only to other CB stations, to units of your own CB station, or to authorized government stations on CB frequencies about-
[1] Your personal or business activities, or those of members of your immediate family living in your household;
[2] Emergencies;
[3] Traveler assistance;
[4] Civil Defense activities in connection with official tests or drills conducted by, or actual emergencies announced by, the Civil Defense Agency with authority over the area in which your station is located.
{B} You may use your CB station to transmit a TONE SIGNAL only when the signal is used to make contact, or to continue communications
(Examples: tone operated squelch, selective calling circuits).
If the signal is an audible tone, it must last no longer than 15 seconds at one time. If the signal is a subaudible tone, it may be transmitted continuously only as long as you are talking.
{C} You may use your CB station to transmit one-way communications (messages not intended for two or more CB stations) only for emergency communications, traveler assistance, brief tests (radio checks) or voice paging.
