Thanks to all that pointed me to the filter gain settings accessible with the Utility. It was set at 2 db which is the recommended value in the K3 manual. Now that I know where the parameter is, I'll experiment more with weak signals. The manual does not suggest going above 2 db claiming DSP operation would be impaired in some way.
I've also concluded that the sharp drop in noise when the filter kicks in is to be expected. I found the same instantaneous drop in noise with the 200 Hz filter is engaged. Not at all annoying; I was just trying to understand this marvelous radio. I'm primarily a CW op and will leave the Rx Eq set at +2db around the sidetone frequencies and all others -10 or better. That seems to suit my ears and my current operating skill. 73 de Clark WU4B -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Received-Signal-Drops-When-Roofing-Filter-Switched-In-tp7609366p7609423.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
