    Quería compartir la reflexión anónima de un colega, sobre &amp;quot;all things technology&amp;quot;.

    @nirro@cascarilla.social lo hemos estado probando un poco más. Fatal.

    @shizamura@ciberlandia.pt also amazing floor

    I left SigDigger running for the last 24 hours in HF @ 32 Msps. You can easily tell when the D layer of the ionosphere vanishes, enabling communications below 10 MHz. Useful? Not much, but damn isn&amp;#39;t it beautiful?

    @g7vkq @scott yes, it is a USRP B200, running at 32 Msp/s. I am using NooElec&amp;#39;s Ham It Up, which shifts HF to 125 MHz (see &amp;quot;LNB&amp;quot; in the top - left, it is set to -125.000.000). Regarding the RX888 I have no idea, never heard of it until now. The specs are a bit odd, though: it says the VGA only applies to HF and VHF?

    @g7vkq @scott 130 Msps is brutal. Do you happen to have any spectrum at hand? I am curious about its performance in LW / MW

    Bom día. Sou espanhol e estou a aprender português europeu. Como é que é tão difícil encontrar conteúdos de Portugal na Internet? (estou a escrever este post porque @nirro quer máis actividade neste servidor).

    I&amp;#39;ve finally tested my 3rd iteration of the varactor-based parametric amplifier. Gain is +20 dB. Test signal was Kate Ryan - Desenchantée (FM).

  • Post #551772

    More about my parametric amplifier, being powered on and off. The input signal is FM modulated, and the audio recording starts with the amplifier off. Then, I power it on right before the &amp;quot;tout est chaoooos&amp;quot; part, and then I toggle the power a couple of times more.

    Detrás de esto hay un cerebro galaxia. Un IQ=5000. Un éxito del iberismo.

    I believe Aulë was a nice guy.

    Also, I love how the following concepts sound in Portuguese to Spanish speakers: - Pet (&quot;esteem bug&quot;) - Car Jack (&quot;monkey&quot;) - Ham (&quot;allegedly&quot;)

    Did you know that the Catalan word for chicken sounds like &quot;chicken disaster&quot; to Spanish speakers?

    @martinho@ciberlandia.pt @RuteRadio@ciberlandia.pt agreed, and I am not even Portuguese.
