As I have mentioned before, I sometimes find it convenient to write raw PostScript. I’ve used it to generate business cards, to make templates for laying out parts for radios and telescopees, and generating score cards and labels. Today, I had an idea for creating a large poster to hang in my office. It turns out that Costco will print 20″x30″ posters for $8.99, which is actually very cheap (almost as cheap as simple throw-away posters). So, I found myself once again coding things up in raw postscript, and generating 300dpi output from that using GhostScript. But unlike previous projects, I also wanted to include a couple of paragraphs of formatted text. I remember reading about The Tinydict system promoted by the Capella Archive. He writes whole books in raw PostScript, which isn’t actually as painful as it sounds. Digging around though, I found that there are a couple of resources thoughtfully archived on anastigmatix.net:
Earlier this year, I blogged about my acquisition of an SDR-IQ receiver, made by RFSpace. I hadn’t had it hooked up for quite some time, so I dusted it off, fired up the Spectravue software that drives it, and did some scanning around the bands. Yep, it still works. I really like Spectravue for the most part. It isn’t that hard to get used to, and allows you to easily scan the ham bands looking for signals.
But the one thing it does seem to lack is some noise reduction. Listening to hours of white noise is a bit fatiguing, and I was hoping that I could find something that would make listening a tiny bit better.
Enter SDR-Radio. It’s a spiffy program that knows about the SDR-IQ, and among other things seems to include three different types of noise reduction, as well as some better (IMO) automatic gain controls. There are aspects of the interface that I find less intuitive, but overall it is a very pretty and well done program. If you have a supported radio, check it out.
