February 15 Meeting: Audio Precision and the Noise Floor

How Low Can You Go?

What are the capabilities of modern test equipment and its ability to test very low noise and distortion devices? Can test equipment of today keep up with increasingly impressive specs? Are the specs real? We’ll review some real world examples from both the electrical audio test world as well as room acoustics testing.

Join Chapter 36 Wednesday, February 15, at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. Audio Precision buys lunch. Members and visitors are welcome as always.

SBE Chapter 36 Gets UHF Amateur Radio Repeater

Mt. Soledad in La Jolla is now home to another radiator, KI6KHB/F. A new Yaseu Fusion repeater is broadcasting on 445.540 -. It is in Auto mode meaning if you transmit FM, the output will be FM. If you’re using the digital C4FM mode, the output will be in C4FM.

Frequency: 445.540 -, PL 88.5Hz, DSQ code: 36

Repeater output is 25 watts TPO on a station master omni antenna right above the roof line at the KGTV site.

Note: This repeater is coordinated with SCRRBA and is co-channel with the WB6AJE repeater on Mt. Wilson in Los Angeles. Outside Oceanside there may be overlap between the two machines so we’re suggesting only use the repeater if within the county.

Local broadcast engineers are encouraged to use the new repeater.

Huge thanks to Chris Durso, Gary Stigall, Bob Vaillancourt, John Bush and many others that made this year long project a reality.
