        Note that this recording does not include the interval signals from the different stations that used Woofferton that concluded the last 10 minutes or so of the program.

    Reception was fine business up in MI, USA on 15245kc. I sent a report to compass.tv to that effect.

    Wonderful hour program led off with a fine history of Wooferton transmitters and ended by repeating various vocal and musical interludes used to mark stations going off-air over the years.

    I really enjoyed joining in this celebration of the wonders of radio, a hobby I have enjoyed for nearly 50 years.

    Well I certainly hope that the segment makes it to air today TUESDAY OCTOBER 18!!! as I could not hear a thing last night which was Monday October 17 on either 17785 or DRM11725. Somebody made a mistake in saying it was to be on Tuesday 17th October, as that was NOT the correct date!
    I hope there is something tonight at midnight South Australia, which will be 1330 UTC on Tuesday (18th).

      Now I DO feel like an idiot! I could have sworn that yesterday was the 17th, and that today (Tuesday would be the 18th)! Please ignore the above post: I don’t know what calendar I was looking at.

      1. Jerome van der Linden

        And YES, it is on tonight. I’m listening and recording the signal on 17785. Better on a nearby KiwiSDR than on on my own SDR, but still very listenable.
        I may even send them a report!

    Wow! No transmissions to South America and Africa! And Woofferton (Encompass) has a good revenue from BBC Africa, which can be tuned here in southern Brasil.

    It is interesting to compare the signal strength maps above for Europe.
    The AMC signal is stronger than the DRM signal. This is because the AMC still has a carrier who’s power is dependent on the volume of the audio hence the ‘C’. The carrier power is reduced during low volume sound. Most AM broadcasters use sound compressors for the maximum volume signal to overcome the noise. DRM has no carrier at all so the field strength is the average power which is lower, but also the received signal strength may be lower because the receiver can apply error correction and still produce continuous sound without interference and noise being audible.

    1. Roseanna - RNEI

      Worth noting that the maps are set to 34dB SNR for AM, 21&23dB SNR on the DRM; aka that is compensated for. It’s much more down to frequency choice than anything else (17 vs 11MHz!)
