REUTERS/Mike Hutchings/File PhotoA nationwide petition was launched on Wednesday in South Africa with the aim of breaking the monopoly state-run electricity utility Eskom has on electricity generation in the country.Hours after the petition was launched by the opposition Democratic Alliance (DA), thousands of South Africans have signed the petition.This came after continuous power blackouts gripped the country recently. On Wednesday, Eskom, which supplies more than 95 percent of the electricity consumed in the country, implemented Stage 2 load shedding for the third consecutive day as a result of a shortage of capacity due to a number of generating units still out of service.Stage 2 calls for 2,000 MW to be rotationally loadshed nationally at a given period. This was the most serious load shedding this year. Previously, Stage 1 load shedding, which allows for up to 1,000 MW of the national load to be shed once a day, had been implemented several times.If the situation worsens, Stage 3, which allows up to 4,000 MW to be shed, will be implemented.Eskom implements load shedding rotationally as a last resort to protect the power system from a total collapse.“Power blackouts are killing jobs and making life harder for South Africans,” the DA said.The DA is calling for the adoption of the Independent System and Market Operator (ISMO) Bill which it said would turn around malfunctioning Eskom and put an end to crippling power blackouts.If the bill was passed by Parliament, independent power producers could play a bigger role in electricity generation.“We need to urgently implement the DA’s plan to break Eskom’s monopoly, and save South Africans money by giving them more options when it comes to buying electricity,” the opposition party said.Electricity generation in South Africa needs efficiency, stability and competitive pricing, the DA said.Also on Wednesday, the Business Day newspaper reported that Eskom wants the South African government to absorb about 100 billion rand (about 7.3 billion U.S. dollars) of its debt as part of a rescue plan for the state-owned utility.International rating agencies have warned that Eskom is a risk to the health of South Africa’s economy.

Comtech Xicom Technology has announced a new GaN-based solid-state X-band block up converter (BUC) that packs a tremendous amount of power into a 5.3-pound (2.4 kg) antenna-mount outdoor unit. This compact, lightweight and highly capable BUC provides 20 watts of linear output power in a 5.8” x 5.1” x 3.9” (147mm x 130mm x 99mm) feed-mountable package designed to handle tough environments and meet stringent X-band RF requirements, while drawing very little power for extended battery operation.Model XTSLIN-20X-B1 features approximately 50 Watts of saturated output power, 25 Watts of linear power using MIL-STD-188-164 definition at mid-band, and more than 20 Watts of linear power across the 500 MHz frequency band (7.9 – 8.4 GHz) over a temperature range of -40⁰C to +60⁰C. This high linear output power level is achieved at less than 120W prime power consumption across all conditions, and comes in a self-cooled feed-mount package that can handle the toughest environments.The key of this unit’s compact size and light weight is its efficiency. It operates as a Class AB amplifier with DC prime power draw ranging from 108 W at 20 W linear RF power output, down to 60W at 2W linear power output. Optional proprietary features offer even greater efficiency at lower output power levels with Battery Saver mode to extend battery life when conditions allow, making this the most flexible BUC of its kind for man pack and transportable terminals.This new X-band BUC accepts a 950 to 1450 MHz L-band input and up converts it to a 7.9 to 8.4 GHz X-band output. This all solid-state unit uses GaN transistors to amplify the signal to achieve full output power. Additional features include temperature compensation, gain control, harmonic filtering, tight gain variation and stability, a serial RS-232 digital monitor and control interface, and options for operating with +24 or +48 VDC prime power, provided over the IF line or through a separate connector.Comtech Xicom Technology manufacturers a wide variety of tube-based and solid-state power amplifiers for military and commercial satellite uplink applications. Their product range encompasses power levels from 8 W to 3 kW, with frequency coverage in sub-bands within the 2 GHz to 45 GHz spectrum. They have amplifiers available for fixed and ground-based, ship-board, and airborne mobile applications.
Sprinter, Aziz Zakari is re-looking his future on the tracks after a disappointing outing at the Beijing Olympics.Returning from a two-year ban for drugs, Aziz could only manage the heats in the 100m and 200m events and says it is perhaps time to give younger athletes the opportunity to shine for the nation.The 35-year-old told Joy Sports Ernest Koranteng that there are a couple of up and coming athletes who deserve attention and support to put in their bid for Ghana, stressing that authorities need to focus on proper home grooming for athletes.“This is the best time for Ghana to start looking at the young ones to start preparation for the next four years. Ghana has new tracks, about four or five and the young ones are there, they have to start encouraging them, helping them with financials and transportation that will encourage them to put their efforts towards the next Olympics.”Aziz recalled that the likes of Emmanuel Tuffour did a lot to encourage him while he was yet young, coming home to compete in nationals. He said Ghana must look to grow her athletes in Ghana, a factor he said was working very well for Jamaica whose athletes are encouraged and supported to train at home.Story by Isaac Yeboah
