[digitalradio] QRP-viewpoint (5 digital modes you need, the only 5.)
The DigiQRP viewpoint other. 1. The RTTY is discrimination mode, not for QRP. We need something other for contests. 2. MFSK16 is good compromise with pic-capability. more info http://www.edutee.net/digiqrp Test results: PathSim Tab, below pdf-file Jaak es1hj/qrp Andrew O'Brien wrote: With the varying discussions about the performance of specific modes , and the comments about lack of activity for some modes, I present the following list of 5 modes the digital mode ham should have...and probably all you really need. 1. PSK31 (and other variants up to PSK250) , plenty of activities both brief and rag chew , activity 24 hours per day. Use PSKmail to send email if you wish. Consider QPSK for tougher conditions . ARQ PSK available in FL-digi for emcomm work (available for free via Winwarbler. FL-Digi , DM780, Multipsk, Pocket PSK and MMVARI. 2. RTTY still DX to be had via this mode and contesting if you like contests ((available for free via Winwarbler, FL-Digi , DM780, Multipsk, MMTTY, and MMVARI. 3. JT65A. If low power DXing is you thing, this is your mode. Brief exchanges of signal reports and location, no conversation mode (available for free via WSJT, Multipsk, and soon to be released JT65-HF) 4. Olivia , weak signal capable plus keyboard conversations.Wide and narrow versions to vary with conditions ((available for free via FL-Digi , DM780, Multipsk, ) 5. Feld Hell. Good speed, surprising robust, a fair amount of activity, easier on your duty cycle that other modes, not good after a couple of beers. ((available for free via FL-Digi , DM780, Multipsk ) That's it, all you need. Yes, I left out MFSK16 despite it being a good mode. It is too fusy at times and most things you can do with MFSK16 ,you can do with an Olivia variant. MT63 is effective but just too much of a bandwidth hog, hardly any activity. If you don't want the super robust brief exchanges of JT65A, you could substitute DominoEX but you could go a week without hearing anyone else. MFTT at quarter speed seems useful, has promise. I won't count ALE as a specific mode but will still argue that all hams should be ALE capable. Still a great concept. Pactor..well great at P3 but costs too many Euros. The rest can be great fun, but if you want just five, the above are what you need. Andy K3UK -- Kirjutas ja tervitab Jaak Hohensee

Agree. QRO RTTY contesting is a plague. LA5VNA Steinar Jaak Hohensee wrote: The DigiQRP viewpoint other. 1. The RTTY is discrimination mode, not for QRP. We need something other for contests. 2.

[digitalradio] Finding QSOs: A word about HRDlog Net
While myself, Sholto, and others have put a lot of time in to developing spotting pages and sked pages to help the digital mode users find QSO opportunities ( see http://www.obriensweb.com/sked/or http://www.hamspots.net/ ) I wonder if the methods behind HRDLOG NET are perhaps the best ? HRDLOG NET integrates with the new Ham Radio Deluxe logbook and, when enabled, it reports your status (on air, or not) and where you radio is tuned. e.g. 2W0RUH is on air 14,230,000 USB K3UK is on air 14,076,000TS-2000 In addition, you can also view a person's log book and see who they may have just worked. e.g Station Start Time BandModeRSTsRSTr KN4SA PA0LEG 2009-04-24 05:0440m SSB 59 59 KN4SA AL7DB 2009-04-24 04:3640m SSB 58 58 KN4SA YU1QW 2009-04-22 04:2540m CW 559 579 The list of who is on air is via call districts and can easily be viewed at a glance. There are not a lot of on-air stations at this moment but it seems to me that this may be the way to go in the future. Automatically posting where you are monitoring, no need to log on to a web page and announce your QRG. Hrdlog net is interfaced with Facebook, so you also use Facebook for buidling friends that you can develop into a special list . You can then view your friends list in hrdlog net and see if they are on air, and where .eg. Friends list Frequency ModeStatus KC8NZJ 144,200,000 CURRENT OPERATING FREQUENCY KC2SCY 14,247,999 You can find HRDLOG via http://www.hrdlog.net/

Re: [digitalradio] Finding QSOs: A word about HRDlog Net
Hi Andy, Let me know what you would like, I'll pass suggestions to Claudio. Maybe other logbook writes would like to integrate with HRDLog.net - it's quite easy. My original idea was simply a web-based logbook status thingy...

Re: [digitalradio] Final results to EA PSK31 CONTEST
A quick review of the results shows just 9 North American entrants out of 163 non-EA entries. Does this simply reflect the band conditions or illustrate a lack of interest in PSK as a contest mode ?
