I updated the 40dB RF Sampler page because although I was very happy with the result, I found out that I forgot a small thing.
To be exact, a small piece of wire which flattens the curve on higher frequencies.
In the winter of 2022 I bought the original TinySA at Eleshop and when they published that the would sell the TinySA Ultra, I ordered it right away.
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.
Hamradio projects
Here you will find various projects I have done or are still doing related to Hamradio.
Also don't forget to check out the Tools and parts section which contains also a lot of projects.
