ERG Gallery - GB3CMS 10GHz Beacon
The Keyer and PSU unit for GB3CMS is housed in this 1U high 19" case.
The keyer sequence is held in a 27C64 (or 27C128) Eprom. Circuit mods, new programming software and Eproms,
and new documentation were made prior to its return to service in July 1997.
The microwave section is in a separate masthead unit which is powered via an umbilical cable from the keyer.
