A lot of modern AM transmitters have a envelope tracking powersupply for the output stage and this often introduce phase-shifts due to voltage dependent capacitance. It was quite noticeable when I measured it on the Danish MW 1062kHz service some years ago. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | 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 -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
