Due to the decrease in budget, the NIST has decided to pull funding for WWV, WWVB, and WWVH. This move will save NIST $6.3 Million USD. (more…)
Power Supplies
How do you clean up the mess of power adapters in your scanner station? Every Scanner needs it's own power brick plugged into your wall. Every other 12 volt device requires it's own wall wart. The worst part about these adapters is the amount of space they take up. Sometimes they are large enough to cover 2 spaces on your power strip. How do we clean up this mess? (more…)
RF Connectors
What is with all the different types of RF Connectors? There are many different types of RF connectors on the market. F, BNC, PL-259, N, DIN, SMA, MCX, etc ;) (more…)
