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 14,076,000 TS-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 Band Mode RSTs RSTr KN4SA PA0LEG 2009-04-24 05:04 40m SSB 59 59 KN4SA AL7DB 2009-04-24 04:36 40m SSB 58 58 KN4SA YU1QW 2009-04-22 04:25 40m 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 Mode Status KC8NZJ 144,200,000 CURRENT OPERATING FREQUENCY KC2SCY 14,247,999 You can find HRDLOG via http://www.hrdlog.net/
