Careful when significantly extending the MiniMod antenna. A point will be reached where the antenna tuned circuit won't peak unless you reduce the value of L2 and/or C13.
I have not tried the following, and this is only an idea:
The current through L2 is limited by R8 390R to stops it saturating on modulation peaks. If L2 (~90uH) is rewound on a ferrite ring or small rod with a few coupling turns and C13 made variable, it may be possible to get a bit more power out. But it won't be much more; the LM386 is probably already near its maximum output.
