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.

PWM issues
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.
Liechtenstein again…
From October 12 – 19 we are/were active again in Liechtenstein, our favorite holiday/expedition location.
Testing my FTV-650B
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.
Working Holiday style
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.
Working on new lightning detector
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.
Trip to Liechtenstein
We just returned from (another) trip to Liechtenstein: the place we visit once or twice a year as a mini expedition and holiday.
New bandfilters ready
Remember that I was rebuilding the bandfilters of my home-brew multiband transceiver? They’re ready now and the results are better than I expected.
New lightning detector
Remember the Lightning detector project we did a couple of years ago? Many of them are currently offline. But we’re working on version 4!
Weather station and Condition Indicator
We’re currently working on a weather station that will also show the current conditions.
