Over the past week or so, I have been playing around with DStarRepeater and ircDDBGateway to learn a bit about DSTAR repeaters, given the progress GB7KH‘s NoV is making. I have made a simplex hotspot with my FT817 and a soundcard interface, although I can see that there is certainly room for improvement. I have ordered a DVRPTR_V1 GMSK interface which has been dispatched so that will replace the soundcard, lowering the CPU load. I am to have the system set up on a Raspberry Pi 2 B, which was released yesterday (maybe today actually). I think I now understand how to tune up those Chinese notch filters, too.
Today my Icom IC-7000 and associated separation kit sold on eBay. I have wrapped them up for posting. I’ll be sad to see the IC7000 go, since it’s been my main workhorse for a long time – It’s been everywhere, that radio; from the university office to touring around Europe! I’ve replaced it with the IC7100 for DSTAR use, as well as an IC7700 (which I have had for a while).
Another batch of QSL cards arrived this morning for M1GEO, MQ1GEO and MO1GEO. I had unfortunately run out so I have ordered another batch of my own cards. They will take a week or so to arrive. I’ll get them out as soon as I can. I also ordered another batch for GB0SNB too, while I was at it!
Today I finished my 4 month stint at ARM Ltd. During my time I haven’t done much with the website, but I have been working on my implementation of a fully KISS compliant Arduino TNC as well as using DSD 1.7 to decode digital modulation such as D-STAR and DMR (and others) using my FunCube and RTL-SDR receivers.
I’ve been doing CQWW as a somewhat casual attempt to work some DX for the past few years, but this year I took it to the next level to organise an event with my local radio club.
There is a full analysis of the log for the weekend, including the KML files from which the following were taken. Where information is not available for a given callsign, the pin has been inserted into the centre of each country with an asterisk or question mark to indicate.

Today I purchased an Icom ID-5100 and fitted inside the car. I have been eating up the miles driving back and forth to Cambridge on my industrial secondment.
This weekend we took the 14 MHz home-brew beam out for LEFARS annual field day at Alymers Farm. Conditions were not so great, but we managed to work some nice DX including VK6, plenty of North America and Canada, and several more rare locations.
Ordered a 144 MHz Anglian Transverter from Sam, G4DDK, as well as a DEML144LNACK-2N low noise preamp for 144 MHz. I am very short of time of late, but it is my intention to experiment with some EME operation this summer and winter, so I figured I had better start buying.
From 28 June to 2 July 2014, a few of us where about and about in Europe! I drove to the Ham Radio Friedrichshafen International Exhibition for the second time, this time leaving a few days each side to recover from the long drive. In the first spare day we drove into Italy, stopping in Liechtenstein (to say we had been). Going, we drove over the Alps and returned back via the tunnels through the Alps (as it was dark). Utterly amazing drive! As evidence, I offer the pictures below!
An online scrapbook full of half-baked projects and silly ideas.
