Hi Louie, Both CPDR and DX are settings of a Compander, which means compressor/expander. It compresses or expands as needed to increase average power and works somewhat like an RF clipper. It can add close to an S unit of average power. The human voice has an average power of only about 15% of peak power, as I recall. That means for 100W PEP, your voice might average 15W or so. The compander allows you to significantly increase talk power for the same peak output.
DX is actually a higher compression version of CPDR. It picks up about where CPDR leaves off. Note that you will need to readjust microphone gain when you turn on eather DX or CPDR. Set the gain so that the ALC meter peaks just under 0 dB for best audio. 73, Gerald Gerald Youngblood, K5SDR President and CEO FlexRadio Systems(TM) 13091 Pond Springs Road, #250 Austin, TX 78729 Phone: 512-535-4713 Ext. 202 Email: ger...@flexradio.com Web: www.flexradio.com Tune In Excitement (TM) PowerSDR(TM) is a trademark of FlexRadio Systems On Sun, Mar 13, 2011 at 8:56 PM, Louie Hanson Jr. <ah92...@windstream.net> wrote: > What exactly does the function DX (between mic and cpdr do ?
