SSB reception through this filter also makes sense to me.
At present, if you don't have the AM 5khz filter, the 2.7 khz filter is used on receive and there is no AM transmit. The FM filter is supposed to be ready by the end of this week, don't know if it will be or if the firmware is ready for FM, my cat control program cannot set the FM mode yet. All of these are fine tuning details, the radio is absolutely worthy of getting serious about!!! [Elecraft] K3: KBPF3 and KFL3A-6K Roger Marrotte rmarrotte at verizon.net Mon Feb 11 20:38:21 EST 2008 I'm finally getting serious about buying a K3. Up until now I have not paid much attention to all the details, especially those concerning "the filters". For now I'll not get the 2nd RX. It's not available yet, so maybe I'll get it later on. I'll get a couple of CW filters for now. I do mostly CW. I'll get a narrow 1.8KHz SSB filter. I do get on SSB sometimes. I sometimes like to listen to AM but will probably never transmit on AM. I've read the archives but I'm still not absolutely clear about the need for the KFL3A-6K filter in addition to the KBPF3 filter for AM listening. I see the need for the KBPF3 for AM listening outside the ham bands. What will the KFL3A-6K filter do for a casual AM listener? Will there be a noticeable narrowing of the AM signal without it? If the AM will sound better and/or be better filtered with it, I might as well get it. I'm cheap but not that cheap. Roger, W1EM +++++++++++++++++++++++++++++++++++ I believe the only real issue with the FM filter in AM mode is in transmitting and risking out of bandwidth transmission. The DSP would need to hold the AM XMIT to the legal limit if the XTAL filter doesn't. Al WA6VNN **************The year's hottest artists on the red carpet at the Grammy Awards. Go to AOL Music.
