The SP3 is reasonably flat from 100-20,000 Hz. It can reproduce somewhat lower pitches, too. It’s not a brick-wall function. A bit of EQ can be applied if the source provides it.
The SP3 is thus suitable for a wide range of material, including high-quality broadcast voice, ESSB, and even music, but not counting subsonic Earthquake mode, etc. We did not design it to be used exclusively for narrowband voice. 73, Wayne N6KR ______________________________________________________________ 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
