Do you change the settings in the "Global Settings" that is labelled Sample Rate? I have questioned that my 5000A filters are not as sharp as the 3000 I had a year or so ago, what is the best settings for sharp SSB filters? Is it correct that the RX Buffer Size in the DSP menu effects filter sharpness? I set mine to 4096 (max).
Joe N9VX ------------------------------------------------------------------------------------------------- You did not assume incorrectly. Those are exactly the benefits of using lower sampling rates; lower latency and sharper filter skirts (assuming the DSP buffers stay the same). The downside is that you cannot "see" as much of the RF spectrum due to the lower sampling rate. I routinely use 1024 x 96KHz on my FLEX-5000/3000 because it provides the best compromise for phone & digital modes which is what I primarily operate. -Tim -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of David Walker Sent: Monday, October 11, 2010 4:32 AM To: [email protected] Subject: [Flexradio] 48000 v 96000 Sample Rate Hi folks, Is there any benefit to running 48000 kps over 96000 bandwidth on the flex. My current settings is 1024 x 96000. I would assume (maybe wrongly) that 48000 would provide less latency and perhaps better filtering?
