>Hey Rich, do you have any plots from the spectrum analyzer of this?  

€    Some of the tests were done by a friend using a spectrum analyzer at 
his place of employment. The other tests were done by a third party.  

>I don't doubt you, it would just be interesting to see.  

€   Spark transmitters undoubtedly made RF.
