User daily time limit for HF users is defaulted to 30 minutes. The PMBO operator may change that default, or customize it for different modes (pactor 1, pactor 2, pactor 3) and different users. If you have specific larger needs, email your request to the PMBO or RMS operator (pmbocallsign@winlink.org). There are no User daily time limits associated with a RMS packet gateway or Telnet.
