During the summer season bats fly around almost every day in the twilight. I spot them in the evening, when they fly along our house and hunt for small flying insects, mostly mosquitoes and flies. Their soundless air show is a joy to watch.— more →
Some years ago I provided some workshops on local radioclubs, demonstrating the capabilities of Arduino boards. Along with the workshop I handed out a quick reference card to get started. Recently I was asked to do another workshop, so it was time to update my QRC. I thought it’s worth sharing, so here it is. — more →
Recently I have transferred the CLog software to my GitHub repository. I’m currently centralizing my code at GitHub since I wanted to get rid of sourceforge.net (my previous repository for CLog) and prefer GitHub nowadays. — more →
The Neophyte receiver is an easy-to-build receiver, already built by lots of people. Many radio clubs used it as a project for starting builders. It was developed by John WA3RNC and first published in QST, February 1988. The circuit can be used to create either a 80m or a 40m receiver, depending on a few capacitors. The 60m band is just in between, therefore I decided to find out the correct caps for this new amateur radio band (well… at least new in the Netherlands, from December 2015).
During the PACC contest last weekend we had contact with lots of Ukranian radio amateurs. However, there is a terrible war going on in this country. So… does this war impact amateur radio activity in Ukraine? — more →
I thought it would be nice to chat with some local radio amateurs on my way back home. I often talk to Adrian PA0RDA while driving home (by car) after work, using the local 70cm repeater PI2ZST, so I decided to prepare my bike for this UHF band. — more →
