Yesterday I finally added a tube tx to my tube rx. Output power 1W at 100V anode voltage. The Superhet rx works with only 12V anode voltage.
The first test at a summit is still pending and will take place in the next few days.
Here is a video with an introduction and some details about the tx. In my youtube channel there are some videos about the rx, but unfortunately everything is only in German.
