That can be debated, no other OS (MacOS/Linux/*BSD) identifies it as a microphone. And why is there no clear option to enable/disable the "software pre-amp" in Windows? On the filter discussion; I have (apart from FM filter) 2.8 KHz filters and 400 Hz filters. Very pleased with that. I am not a contester so I want the full SSB bandwidth, mainly for waterfall view in digital modes. 2.8 KHz because I couldn't be bothered with filter matching in main and sub receiver... 400 Hz is kind of the smallest BW usable for digital modes anyway. If you want to go tighter than that (for CW or possibly PSK31), use the DSP filter is my advice. /Johan ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
