Salvo, Including you, many others have discussed the short comings of running ASFK RTTY with PowerSDR. There have been some "Band-Aids" done in the past, but what is really needed is a more functional implementation ASFK RTTY mode. As the first step to that end goal of making PowerSDR the ultimate digital mode radio was the recent enhancement to center DIGx mode filters to be at the ClickTune Offset value and refactoring the filter widths, but more needs to be done. To that effect, I have written a "User Story" (US) for FlexRadio defining a more usable ASFK RTTY mode for PowerSDR that includes the suggestions you have made here. It would in essence replace DIGL. Defining a US is the first step in a program change/enhancement in PowerSDR, so the initial ground work has been accomplished. Hopefully it will rise to the top of the feature list in a future PowerSDR release. I may be able to help it along by doing some of the coding when I find the time, but I am a NOVICE C# programmer and I am learning as I go, so don't count on anything in the near future.

With the biggest respect to the experiences and the personal opinion of everybody I would suggest to use MMTTY. Its internal filters are far superior to the those inside FLDIGI. That's all, IMHO. All but not enough for sure. Just to say more about my personal experiences and views I would try to write here some more deeply about my RTTY activities. Just for QSO or exotics modes DM780 and FLDIGi may have some attractions, but no way if you want to do something of relevant in RTTY. For relevant I mean not only some RTTY QSO, but also extenuating RTTY pile ups and, why not, those roaming RTTY contests. The combo N1MM+MTTY is unbeatable, even AFSK: filters and great automation, Filters by MMTTY and automation by N1MM. {(ALT-F7 +1) it's a wonderful, even if manual, SPLIT command when you listen '1 UP'} The Logger side of HRD is also useful to maintain and to give relief for the LoTW and eQSL management. Load it exporting from N1MM to have electronic QSL submission and checks. First of all remember to have a TX filter defined in POWERSDR(tm) for any mode you will use, just not to spread too much signal out of the needed hundreds Hertz pass band. Then have some macros, thanks FLEX for a very well declined CAT commands set, useful to change filters, set offsets and so on. For POWERSDR(tm) remember to place some offset values, those right pse, so when you will spot anybody the spot would be on the right QRG. This will be also useful to have point and click tuning fully automated well inside the TX filter bandwidth. Than you will have a single logger well suited for several radios just changing the macro set for each one, the same environment to drive in the same way with any vehicle you have. I already done this for a PROIII, a 7600, a 7700, a FT-950 and my love a FLEX 3000. All the radio have filters and more driven by the computer. The logger is the focus, in QSO, in the pile up and in contest. Well the 3000 with its panadapter does't need large MF filters out of the 250/200 Hz one, you will see the anyway any potential correspondent in the pan-adapter: just point and click to have inside the MMTTY waterfall also. BTW this will work for any audio/CAT interface, from the home made one, to the MicroHam and even to the ICOM USB (AFSK only, sigh!). N1MM is the only logger that I know that have 24 user definable macros out of the QSO input windows with it's own macros. The trick is to learn a logger, N1MM, doing normal activity to become really acquainted to it for any contest. How to learn a logger, easy: have it in everyday usage. How you could use a tricky logger for the everyday use, more easy: having one of this beasts that looks friendly and not a 3270 dumb terminal. Take care to have MMTTY 1.68A and it's profiling file for filters and decode choices. Some are to be modifies, as to get rid of NET or ATC or AFC, be advised. Be advised also that some combined effects of the MMTTY AF filters may seems to be way too much tied to be useful. Time and learning will help to use and judge. DM780 was my first choice, but I switched to MMTTY to have FSK, N1MM was a must doing my small contest activity. But it's also the main choice, together with FLEX, for IQ1RY RTTY 24H contests and we win something last years. Thanks to all on bands and there. I think it's a good point. The radio macro set was the same, the radio changed, but nobody cared about ... well ... almost: HI! The first operator, IK1HXN, never used a FLEX before: his first run in a 24h contest went to a win. As the N1MM and macro commands was well know by him. With the FLEX it went more easy and effortless for the 2010 DL-DX than for the 2010 Volta, that was played with a traditional radio! There will be much more to explain in between those points to glue all together and to make a full blown working picture, but it would be too much here and I don't want to stole more space. A usual, I hope that my language was clear enough to be readable. 73 de iw1ayd Salvo _______________________________________________ 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/ _______________________________________________ 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/
