In a previous video I have shown how to generate test signals for a VOR radio navigation system for aircraft.. This article will take a look at another radionavigation system, the Instrument Landing system or “ILS” for short. The ILS is used by aircraft around the world every single day. It is designed to guide … [Read more…]
The Tektronix Vector Signal Analysis Software SignalVu has a great mapping tool, Tektronix RSA Map. Unfortunately, the default map supplied is extremely coarse and not really useful for real world measurements. This short article is going to show how to acquire free map files from openly available sources. If you use Tektronix SignalVu, odds are … [Read more…]
After posting the teardown video of the Tektronix RSA306 USB 3.0 Spectrum Analyzer on my YouTube channel, someone asked me to verify that the IF sampled by the Linear Technology 14-Bit / 125 Msps ADC is really at 140 MHz.

This article shows how to use off-the-shelf parts to improve the performance of a radio scanner in the 800 – 900 MHz band. Furthermore, it shows how to expand radio coverage by using two different receive antennas at the same time. For some reason, my new BCD996XT scanner wasn’t working as expected on the statewide … [Read more…]
