You might first want to tty a Software application called winrad it's free and would give you an idea if this well work for you. I have a couple of DSP units here if you want to borrow one to try and see if it will work out. http://www.winrad.org/Robert Parker VE3RPF ________________________________ From: Dave Casement <va3dac@xxxxxxxxx> To: karc@xxxxxxxxxxxxx Sent: Tue, March 23, 2010 4:24:09 PM Subject: [karc] Re: Audio DSP Hi Rob, Sorry if my original message was confusing. What I meant was I need a external audio DSP that will cover up to 5khz. I have not used one and not sure if they will cover more than the usual 3 from a ham rig. I need this for a work application where I need from approximately 100 Hz to 5KHz. I need it to be able to roll off above that. Does that make it clearer?
