It was happy SDR day. I had squandered $18.00 of joint marital funds and had waited days for my digital equivalent of Ralphie's Little Orphan Annie's secret decoder ring to arrive. I was hoping the message wasn't going end up being something like "Drink Ovaltine." It was the best investment I have made in a long time, although I don't think Katie is as enthused at the cacophony of dronings, squawks, squeaks, beeps and hissing sounds continuously emanating from my office. The paltry funds have let me peer deeply into the mysterious world of radio frequencies which I haven't done since I built a crystal radio as a kid. What fun, but does it really work?
