Yes. We're pleased to see some excellent test results, including 106 dB of IMDDR3 at 2 kHz for both the 200- and 400-Hz filters. (The K3 came in at 104 dB for the 400-Hz filter. The 107-dB reading is within the usual +/- 1 dB lab/tech repeatability figure.) Also worthy of note: sensitivity of -145 dBm for the new Preamp 2 on 10 meters. This preamp is also used on 12 and 6 meters. I checked with Rob, and that blocking dynamic range number (>154 dB) is *not* a typo. He said he saw less than 3 dB phase noise degradation at 100 kHz with +19 dBm fed into the radio, and stopped at that point. I guess there's no point in melting the signal combiner :) (By the way, Rob's K3S BDR test level of +19 dBm is exactly 10 dB *higher* than the preamp-OFF ADC clipping level of the 6700. With preamp ON, it would clip at an estimated -11 dBm.) 73, Wayne N6KR ______________________________________________________________ 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]
