Reply to David's, G4EBT bulletin.
Thanks for the info on Sir Douglas Hall, and the "Spontaflex" circuits.
I have seen a few, but not 2 transister LS ones. I don't think it was
at the site you sent though. So when I get back on the internet, I will
try it. http://freespace.virgin.net/spontaflex.reflex/
I have had a few circuits sent to me via packet, thanks again chaps,
but will have a few problems getting the parts. (It's not like it was 40
years ago) ;-)
I have built one, and yessss...... it is working, just. It is one out
of a 1972 Practical Wireless. I have been trying this circuit for a long
time. It is a very simple one, but I am having a few problems. The first
one was the choke. I thought I was using a 2.5mH choke. It was the size
of a resistor, but looking in an old catalogue, I think it was a 2.5 uH.
The other main prob. is it oscillates at the LF part of the band, where
all all my other projects through the years oscillated at the HF end.
Hope you all know what I mean, I'm loosing myself now.
