This weekend I switched on the K3S and operated in the CQWW SSB contest. It wasn’t a serious entry as family life still needs to continue. Sam managed to keep the kids safe, fed and entertained for most of the time allowing me to operate. I had a couple of technical issues at the start of the contst. My Ultrabeam was showing a high SWR which almost stopped me taking part at all. In the end, I remembered there is a calibration routine built into the controller. Once I recalibrated the antenna all was well. The other issue is RS232 stopped working around the time I was fixing the antenna. This turned out to be a hardware fault. I hadn’t screwed the DB9 into the back of the P3 and it had fallen out. Doh! Fixed and no more issues.
My target was at least 400 QSOs, 55K points, 20 Zones and 80 DXCC. I didn’t reach the zone or DXCC targets this time. I made 3 QSOs as a result of a CQ call and the rest were all S&P.

Many contest groups around the world use a hotel/butler bell to indicate a multiplier has just been worked. Jeeves is a modern, automated replacement for the bell which can be installed in or away from the working area. It also doubles up as 12v lighting for the area.
When a QSO is logged, a packet is broadcast from N1MM+ which Jeeves captures and inspects. Depending on the multiplier status of the QSO, the LED string changes colour and dances to match the 8 possible states. This is ideal for contest sites where the communal area is away from the working area and a bell may not be heard. It allows the non operators the fun of keeping track on the progress of the contest. A bell also sounds for 25ms.
My installation now requires no setup for a contest other than plugging into a 12v source (and mains if the bell is to sound).
It might be possible to use one of the ESP8266 boards available with a built in relay if you can ensure that you can access spare IO pins to run the LEDs.
It is important to use 12v LEDs and power them directly. You will not be able to power these from the ESP device. Also, consider that you can use even longer runs of LEDs by purchasing another string and plugging it into the end of the original. The only thing to consider is the volt drop so be prepared to feed 12v directly into each string. If you don’t then you will find the LEDs may sparkle or not show the colour you are expecting.
I received an email from someone in the US who had just built one of my Thunderbolt Monitors. He casually asked if there was a way of showing EST rather than UTC on the display. Whilst on a computer this would be easy, it is a little harder on NETMF due to the fact it doesn’t understand timezones. It isn’t just a case of subtracting 5 hours from the UTC time as we also need to consider daylight savings time.
After some research, I put together a code change which appears to work for him and should handle the daylight savings rules too. Before I share the code I must warn you that this is a little rough but solves the problem. I will not be releasing this in the main branch but you should be able to hack it in if you really want it.
Add the following to the end of the class of program.cs.

I changed the U/G to an E to signify Eastern time but feel free to ignore that or even replace it with just a space instead.
