Belevenissen van een radio amateur
April 1st 2025 I bought my zBitx V1, which was promoted as a “CW Dream Machine”. It turned out to be a CW nightmare. CW was close to unusable. Keying was buggy, elements were missed or added and soon the zBitx ended on the shelf, where it remained for a couple of months.

A couple of months ago I bought a zBitx; an experimental transceiver from HF-Signals. Currently, zBitx V2 is available, but there’s still a struggle going on to get the zBitx V1 to function properly.
A couple of weeks ago, I started buiding a new power amplifier for portable use, mainly with my Elecraft K1. Now, the project has finished.
The sniffer project has ended. 34 kits were sold and customers are happy with the result. We also sold 4 UHF sniffers with a frequency range of 100MHz – 2,5GHz. They are all sold out, but there are some sniffer PCB’s left. You can find them in our webshop.
Currently, I’m working on an RF sniffer that also can be used as a mW meter. It’s based on an AD8307 logarithmic D/A converter.
Our stay in Liechtenstein provided interesting discussions. Especially controlling the FANs of Bart’s (PA3HEA) home made transceiver gave us some interesting food for thought.
From October 12 – 19 we are/were active again in Liechtenstein, our favorite holiday/expedition location.
A while ago I was warned by eBay (you can set warnings if you’re looking for specific items) that another Yaesu FTV-650B transverter was available.
Now summer is starting, it’s time to pick up QRP working in the field. I have a favorite picknick bench which I use for my activities.
A couple of years ago, our radio club published a design of a Lightning detector based on the AS3935 chip and an Arduino Nano processor. That worked, but not with everybody.
