I have not owned or heard a rig that employs IF DSP. I am considering getting either a Jupiter or an Argo V with their IF DSP filtering.

I had the 570 DG and have the Jupiter. Your efforts will be rewarded by controls that work unlike; /archives//html/TenTec/2004-01/msg00848.html (8,187 bytes)

[TenTec] IF DSP vs. AF DSP (score: 1): Author: "Joe" <n9vx@myway.com>; Date: Wed, 28 Jan 2004 11:29:42 -0500 (EST); Dave, I think the DSP in the Kenwood TS-570DG has to do with NR (noise reduction)and not pass band filtering. The Jupiter has DSP pass band filtering and DSP NR. I think you will finding the receiver; /archives//html/TenTec/2004-01/msg00849.html (7,237 bytes)

I did some A/B comparisons between the two and I can tell you the Pegasus DSP is light years ahead of the 570. AFAIK the Pegasus and; /archives//html/TenTec/2004-01/msg00874.html (9,556 bytes)
