FM TUBE TRANSMITTERFM TUBE TRANSMITTERS/AMPLIFIERS (1000-10.000Watt / 87.5 – 108 MHz)

• 1000W (KV 1500), 2000W (KV 2500), 4000W (KV 5000), 5000W (KV 6000), 8000W (KV10000), 13.000 W (KV 15000) or 18.000 W (KV 20000) output power in continuous service: all parts used in these amplifiers are oversized to guarantee the full power 24/24 h even in hard environmental conditions.

• 87.5 - 108 MHz: the frequency of these amplifiers can be easily field tuned from 87.5 MHz to 108 MHz without any parts modification.

• Long life tube. The amplifier uses strong and reliable triodes or grounded grid triodes, widely used in the broadcast field, that assure long life and low maintenance costs.

• High efficiency cavities. A revolutionary cavity design without any sliding contact minimizes the losses, increases amplifiers efficiency and the cavities ruggedness.

• Single tube. No coupled tubes for the best system reliability

• Adjustable output power. The tube’s polarization allows the adjustment of output power simply varying the input one.

• Electronic protections with Digital Pre-heating Timer assures an affordable and stable operation protecting units against major fault conditions. Every alarm event is displayed by front panel LEDs and can be resetted by manual control and/or automatic reset control.

• Full metering. All the main parameters of the amplifiers are front panel displayed by a complete measurement system.

• Soft-start circuit control: the gradual insertion of power supply eliminate transient problems during start-up.

• Forced air cooling. An oversized cooling system guarantees regular functioning and long life for the cavity/tube set even in hard environmental places.

• Meets or exceeds international standards for safety and electrical specifications.

What's your number? http://www.retendo.com.pl/filmy/ motilium domperidone 10mg tablets Anthony has talked about coming to New York because Stoudemire made the move first in the teamâ??s rebuilding process. But the two have spent their time here mostly watching and wondering if the potential the pairing once boasted will ever come to fruition.

Could I have a statement, please? http://www.blue-lemons.com/our-mission levaquin cheap "We're not discontinuing the product," Carter said, adding that Bodybuilding.com is not returning any of the product it still has in its warehouses, while it awaits test results. "We're just simply, as a precaution, making sure these tests are done properly."

I'm at Liverpool University affection job diflucan 150 mg cena unload The initial protests successfully used a major international soccer event as a backdrop, contrasting the billions of dollars needed to host the 2014 World Cup with shortfalls in public services. Authorities hope the papal visit will not provide a similar stage.

An estimated 219 million cases of malaria occurred worldwide and 660,000 people died in 2010, most in Africa, according to the U.S. Centers for Disease Control and Prevention.

I've come to collect a parcel http://www.blue-lemons.com/our-mission levaquin buy These aren’t real losses. They’re not even operating losses. No other federal agency or private company is required to ‘pre-fund’ future medical costs. That is a special anvil tied to the Postal Service, by conservatives in congress so that it has a harder time competing with private carriers. USPS is doing just fine, when you compare apples to apples.

Kualitas Stereo di FM dan AM hampir sama  karena AM Stereo system pemodulasiannya menggunakan system Digital, karena tidak ada system lain.
