I'm looking for clues on the transfer function for gr.pll_refout_cc()
as to how to find optimum values for alpha & beta. 

Using experimental methods: http://webpages.charter.net/cswiger/pll/
( script requires special versions of gr_pll_refout_cc.h,i )

Interesting how, as the input signal is reduced in amplitude and
disappears DOWN into the grass, the output signal remains constant
and the grass comes UP to swamp it! Neat.

Interesting tutorials: http://www.complextoreal.com/
