John Ackermann N8UR jra@febo.com [op25-dev] op25-dev at yahoogroups.comHi Bill and Max -- I'm a little confused where the frequency is set. Are you putting the control channel frequency on the command line with "-f", and then 0 in trunk.tsv, or the other way around? I'm still struggling to get things running here.
