Features: One of my favorites. And it intergrates with HRD. Showing log on internet (websites and various options), license plate with your call (callplate), dxccplate, various log options, iQSL (instant QSL), QSL exchange, Map analysis, eQSL and LotW integration and lots more. Really worth trying...
Features: Might be not as sophisticated as HRDlog. But is interesting due to the handy DXcluster integration. Several colors will give you a quick overview of what you worked/confirmed. The only
problem is the italian language. I quickly made a new diagram legend in both English/Dutch. The program has limited CAT reading for your logbook in collaboration with CAT control software from IZ2BKT (not free!). I tested this software and it works fine but the log implements a strange reading of the frequency (see the photo). Logged one station this way (SV3FUO). Just to test...I expected I could go to the frequency from the station spotted by clicking on it when I had CAT control but that is not the case.
I actually find this cluster thing very useful and something I haven't seen at other online loggers.
Features: Part of the famous QRZ.com pages. Logbook looks are very nice. Best options as far as I can see is the integration of LotW. You can import all LotW QSOs. You can earn some awards and show them on your QRZ page. Very clear and simple interface.
Features: Also one of my favorites. Not only a QSL exchange site but you can use it as logger as well. There are many awards/certificates you can earn and number of users is huge. If you like to exchange QSL this is your site. It is easy to setup multiple activations all within their own time frame and with their own QSLs and log.
Features: You can log online, but you can do that with other loggers too. It is wat it is and the only feature I find useful might be the log statistics. Interface is clear and easy to read.
You will not see LotW and Clublog as I only think a real online logger is one were you can log contacts live online. LotW and Clublog only allows uploading of your log. http://www.hamlogsonline.com is another one. Features: It integrates with Winlog32. Haven't got a account for it. Seems this site is only working with IE?
I've tried to register but haven't been successful. I don't know if direct logging on the internet is possible.
