Rick, Welcome to the club!
What are your audio, hardware and DSP buffer settings and what sampling rate are you using? All of these effect latency. I run @ 96 KHZ sampling rate, RXdsp=4098, TX dsp=2048, Audio buffer=1024 and hardware (Firewire) buffer = 1024 (the last two should be the same no mater what value you use). The latency in my headphones is ~50 ms as best as I can tell from my days setting up flange and delay effects. There is a good discussion on how all of these parameters interact in the FLEX-5000 Owner's Manual, Appendix A. It can also be a CPU core context switching thing too. Placing PowerSDR on a single core may make a difference. -Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Markey, KN3C Sent: Tuesday, December 18, 2007 9:07 PM To: flexradio@flex-radio.biz Subject: [Flexradio] TX Monitor - Newbie Question Am in the process of setting up and learning my way around my new 5000A. This is my first Flex. Very cool but lots to learn I am primarily a phone operator. With my previous radios I have become accustomed to operating with headphones, and with the TX monitor turned on. I tried that with the 5000A and the latency in the TX monitor was so excessive as to be unuseable. Before I go playing with settings, I thought it best to ask if the amount of latency I experienced is typical or is it something that can be tweaked. I looked through the FAQ's but did not see anything relevant. I am using the default settings, and the computer is an AMD 6000+ dual core that doesn't appear to be breaking a sweat running Power SDR. CPU useage is typically less than 10%. Tnx, de Rick, KN3C No virus found in this outgoing message. Checked by AVG Free Edition.
