The {{Title|General Radio 1124 | 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 instrument came with five receiver circuit boards for RF frequencies of 2.5, 3.33, 5.0, 7.335, and 10 MHz, respectively, any two of which could be installed in the receiver module at the same time, in addition to a Loran-C (100 kHz) receiver board and an IF amplifier board that occupy two more sockets. | The instrument came with five receiver circuit boards for RF frequencies of 2.5, 3.33, 5.0, 7.335, and 10 MHz, respectively, any two of which could be installed in the receiver module at the same time, in addition to a Loran-C (100 kHz) receiver board and an IF amplifier board that occupy two more sockets. | ||
