Hi trevor. YEs, I have seen your video on youtube some days ago. I want to made some similar radio. But I believe that yours is a regenerative design, not super-regenerative (may be I'm comfused with this).
On super-regenerative, there are a aditional "quench" oscillation of some kilohertzs that helps to the detection process.
Hi BusyBee, I have seen too yours post. Very interenting info, for sure.
Hi Nick.
Yesterday I was making wy first testings with a 1J24B valve with low HT voltage (max 31V from my desk power supply), but without any result for now. I don't have any amplification
. I need to check the valve connections and the whole circuit. I think this valve need more HT, so I will try with a 1J29B
I have 10 untis each of 1J29B, 1J24B, 1J18b and 1JP24b. May be could order some 1J37b, those appears to be interesting stuff.
