Back in 2012 I wrote about some new test gear that I’d bought for the shack. Well time doesn’t stand still and it’s always nice to have new toys in the shack, especially if they’re useful. My miniVNA Pro always did me well but recently I’ve started doing things on higher frequencies, such as building aerials […]
Toward the end of March I ran WSPR and QRSS on the 60m band for a couple of weeks. I did some experiments on 60m nearly three years ago which gave good results and I was keen to improve that. I posted on the new Knights QRSS list to announce that I would be active on 60m […]
My shack computer is an Apple iMac. For a few years, I’ve operated a lot of data modes and been very successful in data contests. I’ve always enjoyed data modes and in 2012 I operated GO6NHU to celebrate the London 2012 Olympics exclusively using data. Back in 2015, Apple released a new operating system called El Capitan and […]
Over the years I’ve used a few different VHF/UHF aerials here and the one I always found the best was my old Diamond X500. I bought that when I still lived at home with my parents and it moved here with me. It ran my original AX25 packet radio BBS and then MB7UIV and was only […]
I’m a happy owner of two Icom ID-5100 radios, one is mounted in the car and I use the other one in the shack on low power for working the local repeaters. It doesn’t get much use but I’m monitoring GB3CL and GB7TE most of the time. About the only thing which I don’t like about this […]
I’ve been moving some boxes around recently and I unpacked the bandpass filters I built for one of the Martello Tower Group DXpeditions and successfully used again during our activation of the MV Ross Revenge in August 2016. It struck me that I’d never produced a full set of figures showing rejection on each band, insertion […]
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 […]
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 […]
** This is now outdated, I recommend the pre-built image from here rather than following these instructions.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 […]
After my entry a few days ago, I’ve made a video of my Hans Summers Ultimate 3S transmitter going through all four modes in a single ten minute frame. It’s annotated with comments along the way describing what’s happening at every stage.
