RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

DIRECT LINE INTERVIEW JANUARY 2003  - reprinted at the request of RF Power Exchange 

A POWER TUBE MARKET

At the doors of digitalization worldwide, most countries of the world still use tubes in their transmitters. Latin America is a part of this market where companies such as RF Power Exchange excels in charge of distribution of new and reconstructed tubes. In this opportunity Reporting line talks with David Gilden, vice-president of sales and commercialization of RF Power Exchange.

World Radio (RW): Tell us about RF Power Exchange, its objectives and how it gets to be developed?

David Gilden (DW): RF Power Exchange was formed like a result of several months of conversations with the users and the distributors of the market of the diffusion in all Latin America. As many of countries suffered difficult economies, there were two constant orders.

First, they looked for alternatives to the present suppliers in the market. And secondly, they looked for the opportunity to work with one company that could offer low prices with alternatives of high quality. And also they looked for formality and a constant answers to their necessities.

Our company is an authorized distributor for sales of new and reconstructed tubes for transmission from Econco. We offer enormous value and trustworthiness in comparison with the other brands that they are offered at the moment in the market. With Comet AG, we offer condensers with high quality and good prices and superior qualities to those of our competitors.

Also, we are working with products for RF, with the main manufacturers of transistors and modules.

Our goal is to work with the best distributors, which are in charge to provide the pieces as spare part.

RW: Which is the transformation with the greater importance that is occurring in the radial industry in Latin America?

DG: After of months of conversations with the market of radio in Latin America, one of the common questions was if it's more economical to buy a transmitter of solid state accustomed to a level of greater power to the 15 kW for FM.

With Nautel, Harris and BE which they produce transmitters of 40kW of accustomed solid state, this. With solid state there are replacements or changes of no tube, but it can exist the necessity of a new engineer with greater studies in technology regarding solid state.

As far as RF Power Exchange, we can support both options. We can provide the tubes of transmission to those who wish to remain with their transmitters of tube, and also have the transistors or the modules of solid state.

RW: What is your vision on the future of the digital transmissions in the region?

DG: Ours vision of digital technology and its impact in Latin America is more that an economical answer. In the side of the radial market there are great advantages for both standards that compete today, IBOC and DRM. The A.M. improved its sound when passing to digital to a quality like the one of the analog sound of FM. and the digital FM to the quality of a CD. This really is of interests to the end user? If we paid attention to the cost we will be able to see the following thing in Latin America. If IBOC becomes standard of digital radio favorites, we will see transmitters of solid-state digital smaller externally diplex in existing analog transmitters.

If DRM becomes the favorite standard we will see a digital front and retrofits in the existing analog transmitters. On the other hand, also the impact of the radio based on technology is expected in Latin America. For instance satellite, which can get to be expensive. I believe that the manufacturers of automobiles are going to play an important role in this change, when many of the consumers try to obtain this service in their automobiles. At the moment, the taxes are too high.

RW: Do you which to add something else?

DG: Whereas the American and Latin American broadcasters wanted to have a better sound in the case of the television and more options, I believe that the traditional analog systems still would base for the next decade. Due to this, we are going to continue supporting the spare parts necessary to maintain old technology while we got ready to continue with any digital initiative.
