WSPR-X update

Today I posted an installation file for WSPR-X v0.7 r2960:

Changes from r2948 include the following:

1. An intermittent problem with asserting PTT has been fixed.

2. Frequency reports when the Rx BFO is set to a value other than 1500 Hz have been fixed.

3. Error messages from "rigctl", the utility used for CAT control, are now relayed to the user. Perhaps this will help to isolate why some users have found CAT control not working.

Please report bugs directly to me.
