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. […]
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 […]
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.
Over the last month or so I’ve been doing some experimenting using a newly built Hans Summers Ultimate 3S transmitter fitted with the new oven controlled crystal oscillator and I’m now running four different modes in a single ten minute frame with space at the end for a calibration cycle. You should note that to […]
I’ve not posted much this year because I’ve not been doing much new stuff. I’m still messing around with the very low power modes and enjoying that a lot. I’m transmitting WSPR and QRSS all the time and tend to leave the transmitter running on one band/mode for a month or so at a time. […]
I’ve had this screenshot sitting on my desktop for a while because I think it’s quite interesting. It shows my 20m QRSS signal from when I switched the transmitter on, for a period of nearly four hours. You can see how it takes almost an hour to warm up and calibrate itself to the correct […]
I know I’ve not updated this blog for some months but don’t panic, I’m not actually dead! Although I’ve not done much operating this year, I have still been playing radio. I’ve been melting a lot of solder building WSPR and QRSS transmitters and there’s normally some RF being transmitted on an HF band somewhere […]
The 60m band is fairly new amateur radio allocation, first introduced in 2002 but only to a few countries such as the United Kingdom, Finland, Denmark, the USA, Ireland, Iceland and Norway. I had an experimental Notice of Variation for 5 MHz on my licence a few years ago and I renewed it when we […]
Last month I mentioned that I’d bought a new kit, the “Ultimate 2” transmitter from Hans Summers. I hooked it up with a GPS module and it almost worked perfectly. There were a couple of issues with 2.01 of the firmware and I assisted with beta testing the 2.02 firmware. While testing it, I made […]
I’ve written a fair bit about WSPR in the past and posted reports of where my signal has been heard using just five watts output. I’ve also written about QRSS including details of the transmitters I’ve built and shown reports of where I’ve been captured. A few weeks ago I heard about a new QRSS kit […]
