8 April 2020. How do you setup a static wireless IP for your Raspberry Pi ADS-B SDR receiver, running PiAware v 3.8.1? If you didn’t know, version 3.8.0 has a bug, you must have installed v 3.8.1. Remove the micro SD memory card from the Raspberry Pi. Insert the card into a card reader or…
I have moved my homebrew ADS-B 1090 MHz 1/4 wave ground plane antenna from indoors to outdoors above my garage roof. The Raspberry Pi SDR running PiAware is now located within three metres of the ADS-B antenna. The coax cable feedline is low loss 50 ohm RG58 Cell Foil approximate three metres in length. I…
Inspiration for this project came from Craig WB3GCK, all credits to Craig 🙂 First, this device is not SOTA compliant, however the drive-on mast support is an excellent way to support a lightweight telescopic pole and a HF or VHF antenna for a Field Day, Parks or WICEN (EMCOM) deployment. Position a car wheel on…
Just finished setting up a new Raspberry Pi 3 B+ configured with PiAware 1090 MHz ADS-B tracking software. Tracking Bomber 165 over a fire in Namadgi National Park, which started around 1400h today. 2 am – callsign FireScan is undertaking a survey from 30,000 ft. Radpberry Pi 3 B+ purchased from a local dealer for…
Like many in the amateur radio hobby, I have an interest in listening to my local airport air traffic and en route air traffic operating between Sydney – Canberra – Melbourne centres. I am fortunate that my QTH is located in a RF line-of-sight path to Canberra International Airport (13 km east) and an air…
Saturday 23 November 2019 – I had planned to participate in the WIA VHF-UHF field day, however the forecast temperature is 33 degrees C (hot) and we have a thick red dust haze (hot northerly winds blow red dust from central Australia) which isn’t good for the respiratory system. So the plan for today is…
Saturday 16 May 2019. I am joined by Andrew VK1DA for a joint activation of Booroomba Rocks VK1/AC-026 at 1382m ASL in Namadgi National Park. Starting from Booroomba Rocks car park, the ascent to the summit is 267 vertical metres over 2.4 km taking one hour. Andrew plans to qualify the summit using CW in…
Homebrew 2m/70cm duplexer for 23 and 13cm SOTA activations. Why buy one when you can make your own? All components are mounted on a single sided copper clad board. I will use my FT-817 at 1 watt to drive the 23 and 13cm transverters via the duplexer. The duplexer will permit instant band chages. SG-Lab…
Peter VK3YE recently published a 2m rectangular loop antenna article in Amateur Radio Magazine edition 5 (Sep-Oct 19). The feedpoint impedance of the 2m rectangular loop is 50 ohms thus avoiding the need for a 1/4 wave impedance transformer. I have constructed the lightweight 150 gram (5.2 ounces) antenna and plan to use it for…
15 watt QRP HF L-match for portable operations. Peter VK3YE published a QRP 7 MHz to 52 MHz (40m to 6m) L-network ATU project and circuit diagram in VK’s Amateur Radio magazine , Edition 5, May 2017. I have constructed the L-match ATU and added a 5th inductor L5 4uH for matching on 3.6 MHz…
