  2. Amateur radio homebrew - Wikipedia

    en.wikipedia.org/wiki/Amateur_radio_homebrew

    Homebrew is an amateur radio slang term for home-built, noncommercial radio equipment. [1] Design and construction of equipment from first principles is valued by amateur radio hobbyists, known as "hams", for educational value, and to allow experimentation and development of techniques or levels of performance not readily available as commercial products.

    Smaller in size than "boat anchors", "glowbug" is a term used by US amateurs to describe a simple home-made tube-type radio set. The majority of glowbug transmitters are designed to be used in the CW radiotelegraphy mode. [21] Glowbug transmitters having simple, tube-based designs were part of many beginner ham stations.

    It can use SSB, FSK and CW on all bands. [33] The TS-820S' power consumption is 57 watts (with heaters on) when receiving and 292 watts when transmitting. The transceiver's peak envelope power output on SSB and CW is about 100 watts, and about 60 watts on FSK. Its tubes are tuned manually, using the transceiver's drive, plate and load controls.

    Usually a WSPR station contains a computer and a transceiver, but it is also possible to build very simple beacon transmitters with little effort. For example a simple WSPR beacon can be built using the Si 570, [5] or Si 5351. [6] The Raspberry Pi can also be used as WSPR beacon.

  7. QRP operation - Wikipedia

    en.wikipedia.org/wiki/QRP_operation

    Example of transceiver optimized for QRP CW operation: Elecraft K2 Many of the larger, more powerful commercial transceivers permit the operator to lower their output level to QRP levels. Commercial transceivers specially designed to operate at or near QRP power levels have been commercially available since the late 1960s.

  9. QSK operation (full break-in) - Wikipedia

    en.wikipedia.org/wiki/QSK_operation_(full_break-in)

    QSK operation is a technical challenge: It requires very fast T/R RF switches at the high power and voltage side of the radio transceiver. Such switches must be controlled automatically by the telegraph key, and as such they must be rapid enough to be perceptually undetectable by the telegraph operator.
