Where is W1AW located?
Newington, Connecticut
W1AW is both the amateur radio call sign and the primary operating station of the American Radio Relay League (ARRL). This station, which is commonly called the Hiram Percy Maxim Memorial Station, is located on the grounds of ARRL Headquarters in Newington, Connecticut.
What frequency is W1AW?
Frequencies: Morse code: 1.8025, 3.5815, 7.0475, 14.0475, 18.0975, 21.0675, 28.0675 MHz, 147.555 MHz. Digital: 3.595, 7.095, 14.095, 18.1025, 21.095, 28.095, 50.350, 147.555 MHz.
What frequency does Morse code use?

| Frequency Range | 3 kHz – 250000 MHz |
| Mode | CW |
| Modulation | OOK |
| ACF | — |
What callsign was used by the ARRL Headquarters station before w1aw was assigned to it?
1MK
It was in about 1924 that the boys at 1045 Main Street, Hartford, put the first station on the air. The call was 1MK, applied for and duly assigned to ARRL by the Federal Radio Commission.
What is a CW oscillator?
In a radio receiver, a beat frequency oscillator or BFO is a dedicated oscillator used to create an audio frequency signal from Morse code radiotelegraphy (CW) transmissions to make them audible.
What is a code practice oscillator?
Code Practice Oscillator Kit. The T-Tone Code Practice Oscillator uses a “twin-T” oscillator circuit to provide a shaped sine-wave tone, which is much more pleasant to listen to than the 555 timer-based square wave oscillator typically found in CPOs.
Is CW Morse code?
Sometimes the abbreviation CW is used to denote a Morse transmissions. Essentially CW refers to a Morse transmission using a radio signal – the abbreviation coming from the fact that it uses a Carrier Wave, or Continuous Wave that is interrupted.
Why is Morse called CW?
International Morse code today is most popular among amateur radio operators, in the mode commonly referred to as “continuous wave” or “CW”. (This name was chosen to distinguish it from the damped wave emissions from spark transmitters, not because the transmission is continuous.)
What is a beat frequency oscillator used for?
Introduction: The beat frequency oscillator (BFO) is used for CW and SSB reception. The oscillator generates a signal which is mixed with the output of the IF amplifier in the detector to produce an AM signal that can then be demodulated by the detector.
What is a CW keyer?
Electronic Morse keyer: This term really refers to a keyer that includes the mechanical paddle as well as the electronics to create the dots and dashes. Some keyers incorporate a reed relay so that high voltages can be switched – this may be required if valve vacuum tube transmitters are being used.
Is Morse code dead?
You only have to listen to the bottom end of most of the HF bands (such as 40m (7 MHz) or 20m (14 MHz) to realise that far from being dead, Morse code is alive and well and being used by increasing numbers of hams.
