Default low distortion antenna amp

Hi All,
The article below shows a low distortion antenna amp for BCB and SW.

http://www.kongsfjord.no/dl/Amplifie...And%202N3053%2
0Amplifiers.pdf

Note the wrap.

When built as a push pull it has stated specs such as
12db power gain
ICP2in +100
ICP3in +35
Flat from 100khz to 30 Mhz
I'm interested in comments, and I'm also trying to generate some interest
in maybe some simulations to work on biasing options.
The author states more work needs to be done on transformer winding
ratios.
Take a look, it is an interesting article.
Mike
