Program Files:
- v1.6.7 allows frequency offset from 0 – 200 Hz (equiv. audio freq 1400 – 1600 Hz)
- Default configuration file name is now “config.txt” (will also look for “commands.txt”)
- “log.txt” file shows timestamped error and status change events.
- Supports WSPR and FST4W-120 (one or the other, not mixed-mode)
- For WSPR operation, the first entry in the “config.txt” file should be “MODE WSPR” (or “mode wspr”)
- Fixes (?) file corruption problem
- In the WSPR mode the 6-meter band now allows operation over same 200 Hz range as on the lower bands.
- There is a shortcut available in the SCHEDULE command, “SCHEDULE A ” followed by the schedule options will set the schedule for all active channels.
- There are additional configuration options in this version
- This fixes a very small timing bug in v.2.3.0, in which the WSPR symbol rate was 0.0075% slow.
- V2.4.0 adds T/R Switch control capability
- Also eliminated the brief transmitter activity at initial start-up
