Short is good, in particular if there is no major variable water (lakes or groundwater) between you and the transmitter. The only downside to really short distance is that the sky-wave comes crashing down in no time, so tracking on the 3rd zero-crossing is very important. I have an animation showing typical skywaves at around 200km distance from Sylt here: http://phk.freebsd.dk/AducLoran/animation2.gif When skywaves are bad, they are as high or higher amplitude as the grounwave and arrive earlier than usual, but I have not managed to capture that and the capture process I use is to resource intensive to run constantly. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
