Amateur Radio

These old radios are not nearly as valuable as people seem to think they are. and the high end Grundig Majestic 7038 USA is no exception to this rule. It is a nice set to be sure, the craftsmanship used to construct these consoles was nothing less than stunning. Unfortunately, they are terribly difficult and expensive to service or repair, which deflates their value greatly. A full blown Grundig Majestic 7038 USA Console, with both, the 4 speed record changer, and the optional reel to reel tape player along with the tilt out radio unit that has Long Wave, Short Wave, and FM capability along with the HI FI built in 6 channel equalizer, if in absolute MINT, and I mean SHOW ROOM MINT condition, with EVERYTHING working properly, tops out at about $800.00 or so. If anything at all is wrong with the unit, it is basically a door stop and is worth perhaps 100 to 200 depending on the completeness of the accessories (no missing parts), and the overall and general condition of the cabinette, knobs, et all. There were however two basic variations of this console, the HI-FI (Predicessor to Stereo) unit, and an actual Stereo version. The Stereo version is worth a bit more than the HI-FI version, and is somewhat more difficult to find. So, if your one of the lucky dogs that has the full blown high end 7038 Stereo version, that unit might top out, again in WORKING showroom MINT condition, at around 1000 to 1200. Again, anything less than showroom working mint, dings, scratches, non-working components, well, the value drops down and down very quickly.

A "ham" (amateur) radio station consists of two essential functional blocks in
addition to the licensed human operator ... a radio transmitter and a radio receiver.
The ultimate purpose of the package is 2-way communication with another
amateur station that is similarly equipped.

Except in certain few specially-authorized cases, one-way 'broadcast' transmission
is not permitted, so a typical communication follows this format:

-- By means of radio transmission, Operator 'A' announces his desire to establish
communication with another licensed ham (amateur) radio station. Operator 'A'
then silences his transmitter, and listens to his receiver.

-- By means of his own radio transmitter, Operator 'B' responds to Operator 'A',
then suspends his transmission and listens to his own receiver.

-- Operator 'A' responds to Operator 'B'. He informs Operator 'B' of his name and
location, possibly describes his radio equipment briefly, and tells Operator 'B' how
well or poorly his signal is being received.

-- Operator 'B' then delivers the same information to Operator 'A'.

-- At the mutual option of both operators, they may end their communication at
this point, or they may continue it for many hours, discussing their mutual
interests in certain technical minutiae of radio communication, their other hobbies,
their occupations, their station in life and career, their families, their vacations,
their literary and musical interests, religion, political tendencies, tastes in food and
fine wine, etc. Exactly like two individuals who meet in a bar or on a train, except
that these two may be separated by half of a world, and have met on ham radio.

And that's how ham radio works.

Amateur radio, often called ham radio, is both a hobby and a service in which participants, called "hams," use various types of radio communications equipment to communicate with other radio amateurs for public service, recreation and self-training.[1] Amateur radio operators enjoy personal (and often worldwide) wireless communications with each other and are able to support their communities with emergency and disaster communications if necessary, while increasing their personal knowledge of electronics and radio theory. An estimated six million people throughout the world are regularly involved with amateur radio.[2] The term "amateur" is not a reflection on the skills of the participants, which are often quite advanced; rather, "amateur" indicates that amateur communications are not allowed to be made for commercial or money-making purposes.

In times of crisis and natural disasters, amateur radio is often used as a means of emergency communication when wireline, cell phones and other conventional means of communications fail. Unlike commercial systems, Amateur radio is not as dependent on terrestrial facilities that can fail. It is dispersed throughout a community without "choke points" such as cellular telephone sites that can be overloaded. Amateur radio operators are experienced in improvising antennas and power sources and most equipment today can be powered by an automobile battery. Annual "Field Days" are held in many countries to practice these emergency improvisational skills. Amateur radio operators can use hundreds of frequencies and can quickly establish networks tying disparate agencies together to enhance interoperability. Recent examples include the 2001 attacks on the World Trade Center in Manhattan, the 2003 North America blackout and Hurricane Katrina in September 2005, where amateur radio was used to coordinate disaster relief activities when other systems failed. On September 2, 2004, ham radio was used to inform weather forecasters with information on Hurricane Frances live from the Bahamas. On December 26, 2004, an earthquake and resulting tsunami across the Indian Ocean wiped out all communications with the Andaman Islands, except for a DX-pedition that provided a means to coordinate relief efforts. Recently, Amateur Radio operators in the People's Republic of China provided emergency communications after the 2008 Sichuan earthquake and US hams did similar work following Hurricane Ike. The largest disaster response by U.S. amateur radio operators was during Hurricane Katrina which first made landfall as a Category 1 hurricane went through Miami, Florida on August 25, 2005, eventually strengthening to Category 5. More than a thousand ham operators from all over the U.S. converged on the Gulf Coast in an effort to provide emergency communications assistance. Subsequent Congressional hearings highlighted the Amateur Radio response as one of the few examples of what went right in the disaster relief effort.

If you are talking about the fraction bar in mathematics, the "fraction bar" is the real name. It is sometimes called a vinculum (although this is a misuse of the word). The fraction bar in amateur radio, also known as the forward slash is officially known as the "fraction bar."

The length of a quarter wave for constructing one end of a dipole is:

234/MHz = feet of wire.

For instance if you have an 80 meter ham radio transceiver and want to construct a dipole to match a frequency of 3.56 MHz (the low power calling frequency) then

234/3.56 = 65.7 feet

Next buy a spool of speaker wire, mark off 65 and 3/4 feet, and pull apart the two wires until you reach the mark. Now you have a half wavelength dipole that resonates near 3.56 MHz.

Start broadcasting in Morse code and I will meet you on the air!

Radios are radios . . . some are used by broadcasters, some are used by the military, some are used by ordinary people, and some are used by amateur radio operators (Hams).

They are a form of communication giving us entertainment, news and other tidbits of interesting information. Radios also create jobs for people.

Radios are useful to hear news broadcast and such you can hear your favoite song or such not questions like these have many possible answers pretty much for the same reasons books are to entertain or inform

In Amateur Radio, PEP stands for Peak Envelope Power. This is the power of the radio wave at the top and bottom of each of it's cycles. For example, if the PEP of a wave is 100 Watts, then at the top of the wave the power is exactly 100 Watts. At the bottom of the wave, things get a little bit weirder, as the power is -100 Watts. I know it's a little hard to wrap your brain around. At the exact middle of the wave, the power is 0 watts.

Disconnect the battery. Take out the centre console and the cover from the gear lever. Remove the ashtray and cup holders. 2 screws hold in the stereo from underneath. they are inserted vertically. Once these are removed the unit slides out.

The government itself does not use amateur (ham) radio. There are thousands of licensed ham radio operators who volunteer to help when the government asks for help. These hams have expensive portable radios, antennas, antenna tuners, batteries, and so forth, that they purchase with their own money

What a mixing console or "desk" does is allow several audio sources to be "mixed" into one. It's called a "summing" circuit. Let's say you were trying to record your friend playing a guitar and singing. You've got a cable coming out of her microphone and another coming out of her guitar. If you were to just cut the ends off the two cables, twist them together, solder a plug on the end and hook them to your tape deck, the sound would be all distorted and nasty. But if you use a mixing console aka mixer it will sound better.


The device described above is a mixing "console" which is a mixer with other things in it, like reverb, limiters, equalizers, delay lines...a mixer is part of a console. The person called a sound mixer runs the mixing console.


In a live concert setting, the person known as the sound mixer, also called the Front Of House Sound Engineer, is the person who combines all of the microphones on stage into a balanced mix for the listening audience.

In a recording studio, the sound mixer is responsible for recording the music onto digital or analog media and then remixing the music into a final mix for release to the listening public.

In film and television production, the sound mixer, also called a sound recordist, is the person on set who records the dialog and sound effects that will be used in the movie or television show.

The first radio used visible coiled wiring and a large circular wire antenna. It did not have a case or speakers built into it and did not look like what a person of today might expect a radio to look like. The first designs of a functional radio were created in 1888 by Heinrich Rudolf Hertz after spending two years studying James Clerk Maxell's theory on electromagnetism, a theory that proposed the existence of electromagnetic waves. Hertz's design was the first properly functional radio transceiver which could send and receive signals, although these signals weren't informative. It would still be decades until we developed this technology to resemble the humble radio we know and love today.

A long time ago, I saw the figure of 460,000 licensed amateur operators worldwide. But trust me, that was really a long time ago. Check out the website of the American Radio Relay League for more up-to-date information.

The government did not take up seriously the licensing and control of amateur and commercial radio operators- all this was in Code then, until about l00 years ago. There was something called the Roberts Bill. Popular electronics writer- and also a Science fiction man- Hugo Gernsback manufactured amateur radio gear and took up the cause of the Amateur- in a very real sense he can be called one of the founding fathers. Naturally, he used his magazines ( Modern Electrics, was one) as a , well repeater circuit. this was around l9ll or so. It fell under the department of commerce- the maritime section- as there were and are many Marine operators- catapulted into the news by the Titanic disaster a year or so later! It should be noted- emergency prepardedness aside- Ham operators were NOT directly involved in the Titanic disaster or rescue attempts and message traffic connected with it. SOS indeed!

The cost of repairing drywall damage would depend on how much damage is done. If you were to buy the drywall it ranges from $10 to $30 a sheet. Plus if you hired someone then it would cost more for labor then it would if you did it yourself.
