[MRCG] RTTY

[Nick England]

Indeed - a "tone-pack" unit such as the AN/UCC-1 could squeeze 16 RTTY
channels into a 3kc voice bandwidth.
Also known as VFCT (Voice Frequency Carrier
Telegraphy) and frequency-division multiplexing.
- AN/UCC-1 RTTY channels are spaced 170Hz apart with 85 Hz shift.
The AN/UCC-1 was standard USN equipment shipboard and the AN/FCC-60 VFCT
system was used by both USN and Signal Corps at comm centers.
