2.1.1.2 PSO Module Alternate I (Harmon AFTAC II) Frequency Data
Table 2-2 provides maximum operating distance and frequency grouping data for frequencies
used by Harmon AFTAC II units.
The maximum operating distances shown, are between transmitter and receiver track wire
connections for end-fed track circuits. For center-fed track circuits, double the distances given to
obtain the maximum receiver-to-receiver distance.
NOTE
The alternate frequencies depicted in Table 2-2 are those typically used
by Harmon equipment and are available for use with GCE. However, the
alternate frequencies use Siemens modulation patterns and are not
directly compatible with non- Siemens transmitters or receivers.
