The RX RF range does indeen suck. Worse is
the TX RF range.
Be carefull when doing other mods. Most
that I have studied will improve RX
reception, but will also adversely affect
TX RF range as they are not impedance-
matched.
This solution should not affect the already
questionable TX range.
I personally built the mod below as I was
not worried about TX range that much. I
get 175 feet RX with my PalmPad from 3
houses away.

cm15a.
Don't forget to stick to 50 ohm (impedence)
components as that is not clearly specified
in hardly any of the plans you read. This
is why TX suffers because it's not
matched/tuned to the antenna (e.g.: similar
to how CBs need to be tuned -- SRW)
