No. I am using BPSK31 for the most part right now, and did not find much info on digu or digl in the manual (page50), but may have missed it. Where would I find more info or theory of operation details? Use DIGU for everything (in most cases). Depending on the program you may find RTTY uses DIGL and then it will use DIGL for all bands. But the most common digital programs, e.g. fldigi, HRD, etc., will use DIGU for everything. Bottom line -- read the fine print for the program you are running but use DIGU by default. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
Re: [Flexradio] DIGL and DIGU - what processing is done in ver 1.8 (andlater if different)

In the Modulation and transceiver mode panel's AFSK sub-panel, select the LSB entry, set its Xcvr Mode selector to RTTY, set its Mark Offset to 0, and set its Optimal Offset to 2210. My question is do I set up PowerSDR in DIGL or DIGU? Tim It only matters depending on the mode. Foe example, PSK31, you can use either USB or LSB and still copy fine. The bigger question is what processing does PowerSDR do in these digital modes that is different from USB or LSB in ver 1.8 (and later versions if different) Tim DIGIx modes bypass all audio processing and turns off the mic so you do not QRM accidentally if you select to use VAC for digital modes (in the VAC setup). This didn't change in 1.9.1 Tom, N4WBS If it moves and it isn't supposed to - duct tape it. If it doesn't move and it is supposed to - WD-40 it. If it's hardware and you want software - FPGA it. ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/ ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/

The bigger question is what processing does PowerSDR do in these digital modes that is different from USB or LSB in ver 1.8 (and later versions if different) Tom, N4WBS While it leads to some extra effort in the original setup, I always use DIGU. This is better for using the panadapter to chase DX. As I recall, USB is wrong for RTTY, so you have to tell your software, one way or another, to run reversed. I don't think this is a particular problem in the end (someone may show that this is less than ideal), but it certainly enables me to work RTTY pileups better in terms of practical operations and it does seem to allow communications. DIGU doesn't seem to affect PSK31 or the other modes, in PSK's case be cause, technically, IIRC, the one value is done by the transition between the two tones, so there is no real issue about mark and space. I don't remember having to do anything special for other of the various modes either. Just RTTY, but maybe I did. Like RTTY, it would presumably be just setting a reverse mode. Setup is getting to be a long time ago! Larry Wo0Z PS, as far as I know, DIGU is USB and DIGL is LSB with most of the various features of voice communications _turned off_.

Larry, I'm wondering if I am missing a trick that I should know. Why is USB better for chasing DX Mark NU6X Intrinsically, it isn't. It has to do with the way the panadapter works. DIGU will have the panadapter display going up instead of down and you end up, of course, listening up for most DX, at least if it isn't on frequency. Now, it's just possible you can work it all from your 3rd party software without reference to the panadapter at all. If you can do that, then it doesn't matter. But, I've always used both the panadapter and the 3rd party code's display (MixW in my case), so DIGU is the way I go. I do CWU for the same reason. DX listens up.
