The {{Title|General Radio 1124}} was available in {{catalog T}} only. It is part of a time broadcast receiver system consisting of a modified [[tekwiki:RM564|Tektronix RM564 storage oscilloscope mainframe]] with a [[tekwiki:2B67|Tektronix 2B67 time base]], and a GenRad-made receiver plug-in. Antenna connections to the receiver are routed through the rear of the modified oscilloscope mainframe. | The {{Title|General Radio 1124}} was available in {{catalog T}} only.
