Updated guide to setting up an APRS RX only iGate using a Raspberry Pi, RTL-SDR dongle and a pre-built image

Initial test of the RPi and RTL-SDR Dongle APRS RX only iGate using Raspbian Stretch

** image has been updated as of 21/04/2018 to resolve the problems some people had booting their Pi ** Note: 01/01/2021 Due to the age of this, I can no longer provide support.  I have tested it recently and it still works. If you’re having problems, please ensure you have read the article fully and […]

Accurate time keeping on an Apple Mac or Raspberry Pi for WSPR/JT65/JT9/FT8

If you use any of the data modes for QSOs such as JT65, JT9, or FT8 or if you operate using WSPR then you’ll know how important it is that your computer clock is accurate.  Anything more than a couple of seconds out and you won’t decode anything and nobody will decode your signal. On […]

Installing a new external ADS-B receiver

External ADS-B receiver using a Raspberry Pi and Poe to power it

Not long after my last post on this subject, back in January, the preamp I had mounted in the box at the top of 30ft of pole strapped to the side of my house failed and I was forced to removed that particular ADS-B aircraft tracker.  I still had my loft unit running and working […]

Learning to code in Python – Hello Raspberry Pi!

Hello Raspberry Pi! by Ryan Heitz from Manning Publications

After my posts about building an APRS RX iGate, I entered into email discussion with Alan, K2RHK who pointed me towards his website specifically to see his experiments in APRS.  While looking through his site, I noticed he’d recommended a book for those looking to learn how to program a Raspberry Pi.  I mentioned that this was […]

Building a Raspberry Pi internet watchdog

Finished Raspberry Pi Zero W internet watchdog

I wasn’t sure whether to post this or not as it’s not specifically amateur radio – But there’s a small amount of electronics involved so I figured it might be of interest. A few days ago while Susan and I were out, I received a text from my son saying “I thought you’d like to […]

MB7UIV is back

A little history In January 2000 I started running the first licensed APRS Internet gateway in the UK originally with the callsign GB7UIV.  Within a week of experiments starting on the 26th January 2000, the gateway was on air and connected to the internet 24/7 except for periods when the connection dropped out and the […]

Setting up an APRS RX only iGate using a Raspberry Pi, RTL-SDR dongle and a pre-built image

After my previous post, it was suggested that an easier way to set up a receive only APRS iGate would be to provide a pre-built image which only needs slight tweaking to go live.  That seemed like a good idea to me so I’ve prepared an image that just requires a handful of configuration changes which I will […]

A guide to setting up an APRS receive only iGate using a Raspberry Pi and an RTL-SDR dongle

** This is now outdated, I recommend the pre-built image from here rather than following these instructions.  I can not support this method any more ** I originally bought a Raspberry Pi back in October 2012 but as I didn’t have a specific purpose in mind for it, I quickly sold it again.  A few […]

ADS-B setups – Comparing internal and external aerials

Following on from my last update, I’ve spent a fair bit of time experimenting with two very different ADS-B aerial configurations.  I have two Raspberry Pi3s, both running identical software and exactly the same receivers, the FlightAware Pro Stick Plus which is a version of the RTL-SDR dongle with a built in preamplifier and bandpass filter. […]

Building an ADS-B receiver setup

I realised recently that I’ve barely touched this blog for most of 2016 and I suppose that’s because I’ve not done a massive amount of radio this year.  My low powered QRSS/WSPR transmitter continues to run mostly 24/7 on various bands (on 30m at time of writing) and my radio high point of the year […]
