The last weeks I have worked on a few small mini projects :

• QRP-Labs broadcast band filter a QRP-Labs filter compatible HighPass filter configured for Broadcast band suppression. 
• Component Measuring Adapter for QRP-Labs filter adapter a small add-on to measure components with your QRP-Labs filter adapter. 

The used Elecraft K2 I got my hands on needed some work on the 20m band and for the alignment of the 20m BPF I could follow the Elecraft manual. But owning a NanoVNA . . . . . well you know where this is going ;-)

I got my hands on a used Elecraft K2 which needed some work. 

And as always I started working on it and added a usb mod. 

My OZ2CPU digitale RF mW-dBm-mV meter has a  input range from 1nW to 1W which is good enough for QRPp rigs and my TinySA has a imput limit of +10dBm / 10mW.  When you want to measure on equipment which gives more output power, you need a serious set of attenuators, or you could build yourself a 40dB RF sampler.

On 30 june 2022 I got a mailing from RaspberryPI  store that the Raspberry PI foundation has released a new PI Pico which also includes a wireless module for Wifi and Bluetooth.

So I ordered 4 of them to get myself familiar with this new microcontroller and to do some experiments with it. And 1 day later postman dropped of a package.
