RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2012, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. Regardless, there are still lots of great
posts in the archive that ware worth looking at. Below are the old forum threads,
including responses to the original posts. Here is the full original RF Cafe Forums on Archive.org

Try searching for "sonar" rather than radar.
The "r" in radar stands for "radio," and the
"s" in sonar stands for "sound." You are working
with sound.
