[Rundfunkorchester] Fm transmitters

[markus westphal]

Hi Lefteris and rundfunorchester,

Nice news. Sounds good, but we haven't tested/heared it yet ;) Lefteris, 
thank you for the work, the research and the links.

I'm currently lost in sound-analysis in pure data (while building a 
modul-rack among other things with tools by William Brent 
<http://williambrent.conflations.com/> (not with tID ;) cause I'm not a 
good programmer). Ives, a good programmer gave me some tips (again). 
Hopefully everything works fine before the concert.

bestwishes;
