Période

1950'S to 1980'S

Canada

Canada includes regions where, prior to the introduction of satellite technologies, long haul communications links were more challenging to establish - such as the far north. This klystron was used in the systems used to overcome the geographical challenges. There is a strong possibility that this klystron was used in Emeril, a small town in Labrador where an antenna for the tropospheric scatter system used by Bell Canada was installed.

Fonction

Used as an oscillator or amplifier to produce ultrahigh frequencies. The electron beam produced is velocity modulated (periodically bunched) to accomplish the desired results.

Technique

Prior to the introduction of satellite communications systems, UHF tropospheric scatter radio links, with multiple hops, were set up to serve areas where the cost or the environment prevented the construction of the long distance telephone circuits used elsewhere. This type of klystron was used in such systems. This type of tube saw extensive service in a system called 'scatter' or 'over the horizon' radio in the Canadian North (see description of system in S.I. file)/ Appears to be similar to the EIMAC 4KM3000LQ two KW Klystron, if not actually that model/ 10,000 watt transmitting tube originally from 'Emeril'/ Source: via R.H. Spencer, historian.
