satnogs_bpsk: Given a High Baudrate parameter, flowgraph fails with unhandled exception

🐞 Problem

When running the BPSK flowgraph with a high frequency and baudrate, e.g. in an observation of the BPSK transmitter of db-dev: TSSK-1, it fails with the following unhandled exception:

[R82XX] PLL not locked!
[INFO] Using format CF32.
[..]
satnogsclient.observer.worker - DEBUG - Initial frequency: 1616250000
satnogsclient.observer.worker - DEBUG - Rigctld msg: 1616219269

Additionally to this unhandled exception which results in a failed observation subsequent observations will also fail. The satnogs-client is then logging satnogsclient.scheduler.tasks - ERROR - Observer job lock acquiring timed out.. Detection and dealing with this situation will be tracked in a seperate issue in the satnogs-client repo.
