Rebuilding and raising my ADS-B receiver

Hexbeam with ADS-B aerial

Earlier this year I replaced my Hexbeam (with another Hexbeam) and I wrote about it on this site. There was a gap of a couple of weeks when I was between aerials and to take advantage of that, I temporarily moved my ADS-B receiver to a temporary stub mast, effectively raising it 7ft from the […]

Building an MMDVM hotspot on a budget

I bought myself a new handheld at the Newark rally earlier this year, an Anytone AT-D878UV to use on DMR. When I went on holiday in October, I took a couple of copies of RadCom with me and in one of them there was a review of my handheld. The author mentioned that he’d used […]

Installing a dipole for 30m

Dipole at sunset

I’ve never had a decent aerial for the 30m (10 MHz) band and have struggled to work much on the band either with my old doublet or the inverted L that I’ve had up for the last couple of years. About a month ago, I realised that I could hang a single band 30m dipole […]

Anderson Powerpoles

Powerpole tail all ready for my PSU

Some time ago back in 2012 I first heard about the Anderson Powerpole in episode 53.5 of the Practical Amateur Radio Podcast and I immediately bought a load of them to use in the shack. I have a number of tails hanging off my PSU, all terminated in Powerpoles. I’ve always soldered the metal contact […]

Replacing my hexbeam with… another hexbeam!

My new hexbeam with 40m

At the end of July, I happened to glance up at my aerial and noticed the 15m element hanging down. It was broken. It didn’t look serious though and I was sure that it was just that the connector on the end of the element had snapped off. Around the same time, I was offered […]

Essex Radar

Essex Radar

I’ve been running an instance of Virtual Radar Server (VRS) for some time and recently decided that this is something I can easily share to anyone who is interested. What is VRS though? VRS is a server running on my network that can take a feed from multiple ADS-B receivers, consolidate them together and provide […]

1090 MHz ADS-B PCB antenna from eBay

That's better - The repaired ADS-B PCB antenna

About a month ago I bought a 1090MHz PCB aerial on eBay and immediately forgot about it. It arrived a few days ago and I had a good look at it before I connected it to anything to try and work out what it actually was. I decided from the construction that it was a […]

QRSS revisited

VE1VDM stacked on 27th March 2019

For the last couple of months, I’ve not done much in the way of traditional radio, largely down to the fact that I’ve been really busy at work. I’ve had lots to do and I’ve spent a month working away from home either on training courses or in meetings preparing for a very large project. […]

An updated internal and external ADS-B comparison

ADS-B receiver mounted on a rifle cleaning rod

It’s been well over a year since I moved my external ADS-B receiver to the top of my Alimast and it’s been performing very well, regularly sitting in the top five of the UK receivers according to the FlightAware statistics page and in the top ten world wide on the PlaneFinder sharers list.  A good location […]
