I ran SpecLab this evening so see if I could detect the carrier of 740 kHz Radio Sociedade da Bahia (Salvador, Brazil) and it came up beautifully, almost as if it had been switched on, at sunset in Salvador:
Copy of trace: http://paulc.mediumwaveradio.org/images/740.jpg Time on the trace is BST (UTC+1). Sunset in Salvador was at 2028 UTC and the yellow trace shows random 'peak frequencies' until 2026 UTC when a carrier is detected at 10 Hz above the nominal frequency of 740 kHz The green trace shows the strength of the signal rising above the noise (red) Paul Troon, Scotland _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
