This article is the first in a series, documenting my journey building a Tayloe Demodulator as an HF radio receiver. This article focuses on a Spice simulation of a Tayloe demodulator. The schematic shown in Figure 1 was created with LTSpice, a well know Spice circuit simulator and schematic capture application. I recommend it. Simulation…
liat is an application that will List It At the Top! Try using it as a companion to the legendary tail utility when watching a log file. It was written to list text that is most recent on the first line (top) and push the rest of the screen down. Instead of pushing the screen…
I went to visit the VLBI antenna near Cedar Rapids, IA one afternoon and took pictures. Here they are.
So, I need to conduct an RF survey of a ground site. The survey’s purpose is to determine if there is any QRM in the area of a ground site receiving UHF radio signals for GNSS with RTK radios. What is QRM? It’s an amateur radio shorthand for man made noise encountered when trying to…
Recently, I put together a raspberry pi3 and an RTL-SDR V3 receiver. Pictures to follow.
The N9SGG TV station is on the air at 447.000 MHz. Pretty cool, eh? We use sdrangle as the app to create the DVS-2 video modulation to send to the radio. 30W output to the antenna is what we send to the discone antenna.
