Default Q multiplier for SX-28

Hi all. I been working on my SX-28 and I wanted to give it a little more
kick and I ran accross a neat little Q multiplier project in one of my old
ARRL Handbooks (42nd 1965) . It uses a 2N1264 or a 2N274 transistor. What do
you think about these old types and is there a more modern transistor that
would better suit my needs? I posted the artical and schematic over on
alt.binaries.radio. Thanks

Why not save yourself the trouble and stick with hollow state. You could add something like this :

or this:

instead.


Just a thought

I agree, this QF-1 would look great with the 28.
I had one years ago that I used with a National NC-125
it worked great.
