    Danke für Ihre E-Mail und die Nachricht. Ich konnte SAQ um 09h nicht hören und dachte das Problem ist sicher auf meiner Seite. Wir hatten Besuch so konnte ich die zweiter Sendung um 1200 Uhr nicht aufnehmen. Es tut mir leid. Ich bin froh daß Sie den Fehler rasch ausbessern konnten.
    Ich danke für Ihre Bemühungen um den Sender und bin immer froh wenn ich SAQ hören kann
    Herzliche Grüße oe3rv Hermann

    Patrik Eriksson – the mad inventor (moved from comments)

    I guess I am one of the closest listeners to the great alternator; just a wee bit north of Gothenburg. But, my receiving equipment is somewhat extraordinary – a self-built analog music synthesiser!
    As the transmitter frequency is well within the bandwidth of my audio processing circuits I realised that they could possibly be used as a VLF receiver. One of the synthesisers VCOs were used as a local oscillator, tuned to something like 17,8 kc/s (btw, ‘the grand old lady’ is far more stable than my music oscillators. There is no room for a mammoth flywheel in here… :) ) A long wire as an improvised antenna was then connected through the synths preamplifer, then mixed with the VCO into the ring modulator unit (4-quadrant multiplier). The resulting signal at a few hundred Hz was then fed through a 4-pole low/bandpass filter and on to the loudspeakers.

    Now, I’m just a musician and audio engineer with limited, to say the least, experience in antennas and frequencies above hearing range. I had a result, but just barely. With careful listening and tuning of the filter I could hear most of the transmission, but almost drowned in other forms of noise in my setup. My next plan is to spend the time until christmas transmission to learn and design a proper antenna, and a better (less noise, more gain) preamp cirquit.
    Such a lovely reason to learn and look deeper into analog topics in this digitalised world!

    Also, I have to admit to a wee bit of ‘cheating’; I did have the dutch SDR online too, as a backup plan / reference. 😉

    I will stay tuned…

    Cheers,

    /Patrik

    Dear team of Grimeton Radio,

    I am very glad that “the ”old lady” is ready again.” and that no permanant harm did remain, and that nobody was injured. I sent my somehow lengthy reception report as smail to you this morning.

    What I have ti mention here is …
    (1)
    Grimeton Radio is the first technical machine, after vessels, which was spoken of in the femininum. I suppose, some of your team were active in the “Swedisch Kriegsmarine” or/and were active as radio officers on civil sea going vessels.
    (2)
    How you managed to take a technical major problem to give sufficient information to your website’s readers, not only explainen very detailed what the reason was, how you managed to cope with the problem and to get on the air soon, to meet the afternoon schedule, all this together is a very good example how to make good, modern and efficient communication work to the public.
    (3)
    I do wish you and all your coworkers, the whole team, the very best in the future, personally and together and with Grimeton Radio (SAQ). I am always very happy (especially as a former professional “brass pounder”) when I here “vvv de SAQ” …

    Kind regards
    Hans G. Diederich, DK2XV
