Been Busy, Pioneer SX-980 Finished, and Anniversary Dinner with SLW

 Got a full post cooking in the pot about the Pioneer, along with some other little projects.

Tonight's project was a lovely Anniversary dinner at the Sonny Lubick Steakhouse in Old Town with my SLW. It's actually Valentine's Day, but that's middle of the week this year, and the nice restaurants are packed.

Anyway....I'll leave you with this, a perfectly "locked" receiver, displaying a Lissajous Figure. The RF drive into the Front End of the radio was about 12dB BELOW the Pioneer spec for locking. This receiver has a very good tuner....

  1. We are also celebrating Valentines Day this weekend. We're going to have Chateaubriand Roast on Sunday - a cut of beef tenderloin seared and roasted to perfection.

  3. Nice Lissajous figure! Outstanding sensitivity also. Pioneer made some wonderful equipment back in the day.

    1. Thanks, FF. It easily exceeds the published specs, so she's a keeper!

    1. Good eye! Yes, they do. One of the signals (the VCO in the PLL) is not a pure sine wave, but more of a sawtooth shaped wave, making the resultant a bit wonky compared to two pure sine waves.
