Iain, I'm going to forward your comments to Laurent at TRX Manager. Thanks. John.

It'd be nice if the NORMalise function for SSB mode could be configurable, and if selecting other filters could, perhaps, adjust the shift so that, effectively, the LO-cut stays the same. Personally, I have a 1.8kHz filter, and use 1.8kHz all the time for SSB - I see no need to let any more than that though to my ears... but I'm not an SSB rag-chewer...... ~iain / N6ML On Thu, Apr 14, 2011 at 11:36 PM, Guy Olinger K2AV <olin...@bellsouth.net> wrote: > Oh, remote controlled...
