Modern BUCs convert from the L band to K u band, C band and K a band. Older BUCs convert from a 70 MHz intermediate frequency (IF) to K u band or C band. Most BUCs use phase-locked loop local oscillators and require an external 10 MHz frequency reference to maintain the correct transmit frequency.
A single-phase, three-winding converter transformer. The converter transformers step up the voltage of the AC supply network. Using a star-to-delta or "wye-delta" connection of the transformer windings, the converter can operate with 12 pulses for each cycle in the AC supply, which eliminates numerous harmonic current components. The insulation ...
In the context of domestic PV installations, the kilowatt (symbol kW) is the most common unit for nominal power, for example P peak = 1 kW. Colloquial English sometimes conflates the quantity power and its unit by using the non-standard label watt-peak (symbol W p), possibly prefixed as in kilowatt-peak (kW p), megawatt-peak (MW p), etc.
myTuner Radio, or simply myTuner, is an Internet radio app directory/platform owned by AppGeneration – Software Technologies, Lda, [1] a development company based in Porto, Portugal founded by Eduardo Carqueja in October 2010. myTuner Radio has over 50,000 radio stations and one million podcasts from all around the world (except in the UK where only UK stations are available).

MW DX, short for mediumwave DXing, is the hobby of receiving distant mediumwave (also known as AM) radio stations.MW DX is similar to TV and FM DX in that broadcast band (BCB) stations are the reception targets.
The type of radio emission is “F1D”, frequency-shift keying.A message contains a station's callsign, Maidenhead grid locator, and transmitter power in dBm. [3] The WSPR protocol compresses the information in the message into 50 bits (binary digits).

The northern (Porto Velho) converter station is connected, via a 500 kV AC collector grid (Coletora Porto Velho), to the new Rio Madeira hydro plant complex.As of January 2013 this consisted of two generating stations: Santo Antônio, close to Porto Velho, with a capacity of 3150 MW, and Jirau, with a capacity of 3750 MW, approximately 100 kilometres (62 mi) away.
