Hi Chaz, Something is clearly missing in this exchange between you and the FCC. The implied stand by the FCC is that a GTEM cannot be used above 1 GHz because the published methodology for correlation has not been proven valid in that frequency range. Rather ironic since the GTEM becomes a more valid substitute for an OATS as you go above 1 GHz. Brent DeWitt Loveland, CO (looking for work since layoff last Friday)

The application was rejected by the FCC on the grounds that as there was no site attenuation requirements above 1GHz. Can some one please explain the logic? If : the application is invalid because of the lack of site attenuation specifications then why does the FCC insist on testing above 1GHz? How can the data taken above 1GHz br OK for the DoC and not for qualifying a GTEM?? For those who may not know: the FCC has published a methodology for demonstrating correlation between a GTEM and an OATS. Our GTEM meets that correlation criteria. Confused in Colorado.

EN 55022 currently calls for stopping testing at 1 GHz... Or does it? What guidlines would one follow to test a 2 GHz PC? Thanks, -- Derek N.
