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 →
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).
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 →
- I included a built-in power supply, so no external power supply is needed anymore.
- The built-in power supply also prevents the PoRG from moving around your shack due to the forces of the connected cables.
- It has different connectors for hooking up the transceiver/receiver and antenna, making it more difficult to accidentally swap the cables, insert DC power into your radio and see smoke appearing through the vents of your rig.
