WBCQ The Planet Announces New Showcase Radio Facility

Plymouth Meeting, PA:

WBCQ The Planet announced today that it is building one of the most powerful and versatile radio stations in the world. WBCQ’s new shortwave radio station, now under construction in Monticello, Maine, features a new 500-kilowatt transmitter from Continental Electronics and a state-of-the-art antenna system from Ampegon Antenna of Switzerland.

The new station, funded by private investors, will be able to direct a powerful shortwave signal to any country on Earth. Our new facility is planned to be a showcase for the radio world and is dedicated to our free speech mission.

The new station is planned to commence operations in fall 2018.

Obviously, the investor has deep pockets and I understand is affiliated with a religious organization. The new antenna and transmitter building is being built on land adjacent to the existing transmitter site.  WBCQ actually broke ground last summer and the massive antenna’s foundation is already in place. The antenna is on site now, but has not been assembled. Most of the construction is on hold during the winter, but WBCQ plans to have this 500 kW station on the air by Fall 2018.

Ampegon says it is about to deliver and install its first rotatable shortwave high-power array antenna on the North American continent.

The system, which will be installed WBCQ in the United States, is designed for the transmission of shortwave signals of up to 500 kW, the high-power antenna offers different radiation patterns, an antenna gain of up to 23 dB and uses a technology characterized by a single-shaft structural design.

Ampegon introduces new folded SW and MW antenna system for broadcasters

Ampegon Introduces New Folded Monopole Mediumwave Antenna System

IBC 2015, September 10, Amsterdam. Ampegon, leading supplier of full range mediumwave equipment up to 1200 kW is introducing a folded monopole 50 kW antenna system with new design concept and optimized antenna structure that brings many benefits to broadcasters.

The folded monopole antenna is fully grounded with no need of a base insulator for the placement of the antenna. This is an advantage for the antenna setup; maintenance of components and auxiliary systems installed on the antenna structure is simplified. For example, no isolated energy transformer is required to power the air obstruction light; the light on the antenna structure is supplied directly.

Constructed as a single unit, the folded monopole antenna consists of the mast and the radiating element. The guy ropes supporting the mast are each divided by a single insulator. The upper section forms the “antenna cage”, which is connected to the mast on one side, and by ropes to the insulated feed point at the base of the antenna. As a result, there are no floating potentials in the ropes or in the steel structure, which might cause electrostatic discharges or flashovers. A minimum number of insulators are installed and consequently the maintenance requirements are simplified and minimized. The newest type of insulator used in Ampegon systems features silicon protection and demonstrates an outstanding ruggedness towards environmental influences, such as air pollution.

Ampegon Introduces New Folded Dipole Shortwave Antenna System

IBC 2015, September 11, Amsterdam. Ampegon, leading supplier of shortwave equipment up to 500 kW is setting new standards in antenna construction. A new antenna design concept and an optimized antenna structure is used for the introduction of the single band folded dipole antenna system, available in the RF power range up to 50 kW and developed for economic and efficient domestic shortwave transmission. The 50 kW system is designed with proven and reliable Ampegon components and optimized to low power specifications, which results in significant simplification without any loss of performance.

The antenna system has outstanding key performance indicators like VSWR ? 1.5 in the operational frequency band (Z0 = 300 W) and a gain of 8 dBi.

The highly cost efficient design has tubular structures for suspension of the dipole, no on-site welding is necessary. It is designed for a wind speed of 160 km/h (survival) according to American Standard EIA-222-F with glass fiber reinforced guy ropes for minimal interference with antenna radiation.

Bucking the trend, Taiwan invests in shortwave infrastructure

While countries like Canada are preparing to tear down their state-of-the-art transmission site, Taiwan appears to be investing in theirs.

Thanks to Andrea Borgnino for sharing a press release from the Swiss manufacturer, Ampegon, who has been contracted by RTI to upgrade two shortwave radio transmission sites in Taiwan.

Ampegon will “manufacture, install and commission a total of ten 300 kW DRM shortwave transmitters and twelve rigid dipole broadcast antennas HR2/2/0.3 securing low and efficient maintenance works.” Ampegon boasts that this is “the world’s biggest SW modernization project.”

Ampegon’s continues in their press release:

The transmitters are manufactured in Turgi, Switzerland while the antennas are designed in and delivered from Schifferstadt, Germany. At the first site near Taipeh four transmitters and two antennas will be installed, at the second site six transmitters and ten antennas. The new infrastructure is partially on air since May 2013 with two most modern transmitters and antennas and planned to be completed in several steps until autumn 2014.

Chi-Ming Wang, Director Engineering at RTI, is extremely satisfied with Ampegon as partner for the project: “Ampegon is very experienced and has delivered shortwave transmitters for us thirty years ago that still work to our full satisfaction. Ampegon offers a complete solution approach including transmitters, antennas, control systems and DRM integration. In addition Ampegon provides the best price/performance ratio”.

Significant benefit for the customer is a reduction in energy consumption by replacing the old equipment which leads to operation at higher efficiency rates. Savings in other operational costs are reached by a fully automated transmitter based on StationMaster Plus control system and because of a decrease in the amount of spare parts due to the market leading technology selected.

The challenges of this project are short delivery periods and the management of local logistics including building and feeder line modifications, while keeping existing old transmitters and antennas on air.

This is the largest contract for Ampegon since execution of the name change in November 2012. It means a significant factory load through 2014 for the locations Turgi and Schifferstadt. The project highlights that AM / DRM radio broadcasting keeps its important role in Asia and other areas of the world.

Radio Taiwan International is obviously not pulling out of shortwave. Neither is neighboring China Radio International.

Note that RTI is not the only Taiwan-based broadcaster investing in shortwave radio; PCJ International has recently completed a series of test broadcasts from their new (still under construction) transmitting station.
