First Tomato Harvest

Our first crop of tomatoes was ready!  Check out the pictures below.

The first feedback from the green shoulder tomatoes are that they taste “sweeter” and “less acidic”  We’ve only had a few of those so far, but some have gotten quite big.

Most of the tomatoes that were ready are romas, and the mother in law has enough to start canning!

RTL-SDR Based LTE Signal Analyzer

Have you ever wanted to detect what network is installed at what tower?  screenshot_01Interested to see how a network upgrade or overlay is progressing?  Or, maybe you are interested in getting a better idea of the relative signal strength of multiple LTE networks, with a passive receiver?  If so, this is the blog post for you.
