Capacity for 8000 bits in 8 read/write plug-in memories. Each memory can store either a single message or a number of sequential messages. Features near-full and overload alarms, "message stop" for character insertion, and full control weight ratio.
There is also a message interrupt switch, variable transmit delay, and options for an additional 1000 bits of memory.
Messages in memory can be interrupted during transmission to insert impromptu additions - all without a discernible change between the transmitted code speed of the recorded message and the added comment.
Memories are plug-in with both 500 and 1000 bit memories available. Additionally, the unit can send any message in memory automatically at fixed intervals as needed, for example, in meteor scatter communications. These intervals are clocked by the 60-Hz line current and can be synchronized to WWV.
A switch on the keyer can turn off the dot and/or dash memories with or without automatic character and word spacing - proving as fully automatic or as partially automatic operation as desired.
The unit also has variable dot to dash weighting, two tune positions including "dot tune" for SSB transmitters, self-test, and off-the-air testing capability, provision for use with many types of keys, a built-in monitor and speaker and a built-in 117/220 VAC power supply.
