Re: [digitalradio] PSK/ digital mode SDR software ?
Andy, By default, for digital RX/TX, you don't strictly need to hear the sound. When you pushed on I/Q interface "Direct via the sound card", you could RX/TX just selecting the desired signal on the waterfall. Now if you want to hear the received sound (the base band demodulated one, not the SdR one), push on "+Speaker" and select the Auxiliary Sound card (to Speaker)". You need a second sound card for this: * a SWL could use the same sound card to RX SdR and listen to the demodulated sound, * as a Ham, you must use a first (good) sound card to RX/TX and a second one (standard) to listen to the demodulated sound. 73 Patrick - Original Message - From: Andy obrien To: digitalradio@yahoogroups.com Sent: Saturday, January 23, 2010 12:13 AM Subject: Re: [digitalradio] PSK/ digital mode SDR software ? I'm sorry I don't understand Patrick. How do you "start" the SDR's reception in Multipsk ? The SDR I have is not playing audio until usual SDR software starts the receiver and audio flows . I do not see that in Multipsk ?

You don't need another SdR (and surely it would be a mess to work with two SdR programs doing the same thing). Simply, indicate in Multipsk which sound card (or sound cards if a speaker is added) to work. That's all. 73 Patrick - Original Message - From: "Andy obrien" To: "digitalradio" Sent: Friday, January 22, 2010 10:58 PM Subject: [digitalradio] PSK/ digital mode SDR software ? > My shack PC has some resource issues when using the only software > that I know of that has some digital mode SDR support, Multipsk.
