Indeed, see the attached plot (from a recording I made earlier this
evening): the master signal is totally lacking the 180 degree phase
code modulation, while the slave signal does have it.

This explains exactly what I've been seeing here on the FS700s.
By default the FS700 runs in an "Auto" mode, where given a valid GRI it
searches and locks to the station with the highest signal strength, but with
both Master and Y channels now having the same amplitude this obviously
becomes a very close call.
This wasn't an issue until yesterday afternoon, but with both operational
units producing errors I eventually realised this was only when they were
trying to lock to the Master and that they would still lock ok to the Y
channel, manually selecting the Y channel resolved the problem.
Whether or not the current situation is deliberate or unintended, having
the Master present again, even in a restricted fashion, does at least
restore proper channel identification:-)
