Long time ago...

1977 just before I got my licence. New shack with new audion and 70cm ATV-RX Big and still in function: The Audion RX 0-V-3 with lot of comfort. All homemade, of course.

Two years later I've build another regenerative (audion) receiver. Now it is a 0-V-3 with lot of bells and whistles. I can switch five bands at that time and has lot of audio-power. This RX is still in the shack and working. It is so stable that I've worked the RS-Satellites receiving on 10m and transmitting on 2m the past seventies. Well, that was a good time as a young boy. :-)
