A 10kW (+70dBm) BCB station a few miles away sitting just below the 160m band is going to be pretty darned tough to get rid of using just the standard 160m bandpass filters. And I know that we tend to think of overload as being a threshold thing, i.e. the offending signal has to reach a certain level before we start seeing IMD products but that is not entirely true. It begins to effect receiving performance long before you reach the level where it begins to produce compression. Getting rid of undesired cruft before it can reach any of the active, non-linear components is always a good thing. I have to admit that the Heros Tiny SCR preselector mated with the F5K looks like a real treat. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN) _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
