RSSI Interference

RSSI Interference

Before diving right in on this topic, we should ask what is RSSI and why does interference matter. First off, RSSI stands for Received Signal Strength Indicator and it’s a measurement of the radio frequency power level present at the receiver (1 and 2). A radio frequency transmitter typically has a fixed power output level. As a receiver moves away or around the transmitter, the received power level varies. RSSI is a way to measure that variation. Typically the variation…

Modified Volantex Ranger 600 Controller

Modified Volantex Ranger 600 Controller

The stock Volantex Ranger 600 TX is as basic as any TX can get. The undocumented throw reversals prompted a closer look at the controller. The terms controller and TX apply to the hand held radio controller used to operate the remote controlled plane, TX will be used going forward. One item that was replaced with a yellow LED was the beep indicator. Since a lot of bench testing was going to take place, the blinking LED would be less…

ESP-32 Flight Datalogger – Thrown off

ESP-32 Flight Datalogger – Thrown off

With a couple of flights done successfully, it was time to go back to the location where the earlier plane Bryce was lost. The area seemed to have something that may have influenced the loss, in addition to other factors. The park is rather small, so anyone walking on the field was a no go. With the occasional walker, the park was clear. The ESP32-Cam system was activated to get a GPS lock, while the routine of preflight was done….

ESP-32 Flight Datalogger – Rise Above It

The data gathered from the flights revealed some interesting things. The first was that the amount of detected networks increased with elevation. The two flight locations weren’t close to any dense residential areas. At ground level, those networks were limited to the immediate area. However, once in the air, that number increased because they were now line of sight. The data logger also captured the three strongest networks detected, along with their RSSI values. Although the network numbers increased, the…

ESP-32 Flight Datalogger – Flight of Leia

Many will think of the hair when they hear this name, unless born before 1960 or after 2010, then those numbers might be fewer. This became the name of the remote control plane due to the large pylons on each side of the fuselage. The plane center of gravity was almost a perfect match to the original. The weight was evenly placed but it was noticeably more than the stock 55 grams. It was flight day after a couple of…
