WThe Gonset Communicator was a series of vacuum tube VHF AM radio transceivers that were widely sold in the 1950s and early 60s. They were designed by Faust Gonsett and manufactured by the Gonset Division of L. A. Young Spring and Wire Corp. Models were built for amateur radio, aircraft radio and U.S. Civil Defense use. The Gonsets were among the first commercial radios available for the post-World War II amateur bands and helped popularize VHF for amateurs.
WThe OpenHPSDR project dates from 2005 when Phil Covington, Phil Harman, and Bill Tracey combined their separate projects to form the HPSDR group. It is built around a modular concept which encourages experimentation with new techniques and devices without the need to replace the entire set of boards. The project has expanded from the original group, and several additional people have been involved in recent HPSDR module designs.
WThe Paraset was a small, low-power, thermionic valve CW morse code-only radio transmitter-receiver supplied to the resistance groups in France, Belgium and the Netherlands during World War II.
WThe SCR-284 was a World War II era combination transmitter and receiver used in vehicles or fixed ground stations.
WThe wireless set No. 11 was a wireless radio transceiver used by the British Army during World War II.
WThe Wireless Set No. 19 was a Second World War mobile radio transceiver designed for use by armoured troops of the British Army.

WYaesu FT-101 is a model line of modular amateur radio transceivers, built by the Yaesu Corporation in Japan during the 1970s and 1980s. FT-101 is a set that combines a solid state transmitter, receiver and a tube final amplifier. Its solid state features offer high-performance, low-current characteristics and its tube amplifier provides an almost mismatch-resistant transmitter and tuner stage. FT-101’s were made with plug-in circuit boards that could be sent to the dealer or factory for replacement or repair. Until then, modular design was unprecedented in the amateur community. This also explains the fact why so many FT-101's are still in use today. The rig was sold worldwide as Yaesu FT-101 and in Europe as Yaesu FT-101 and as Sommerkamp FT-277. Because of its reliability it earned its nickname "the workhorse".
WThe Yaesu FT-450 is an entry level amateur radio transceiver made by Yaesu. It transmits on eleven amateur bands, from 160 meters through 6 meters. It also has a receive frequency coverage of 30 kHz to 56 MHz. The FT-450 features an IF-DSP, which is uncommon for its price range.
WThe Yaesu FT-817 is one of the smallest MF/HF/VHF/UHF multimode general-coverage amateur radio transceivers. The set is built by the Japanese Vertex Standard Corporation and is sold under the Yaesu brand. With internal battery pack, on board keyer, its all mode/all band capability and flexible antenna, the set is particularly well suited for portable use. The FT-817 is based on a similar circuit architecture as Yaesu's FT-857 and FT-897, so it is a compromise transceiver and incorporates its features to its low price.
