Please supply a Curtis-Straus certification agreement. This has been submitted. 2. Please provide peak data for the 1/2 fundamental emissions. It must be shown that these comply with 15.249(d). These readings were taken with no modulation so the peak and average readings are the same. Sorry for the confusion. A revised data table is attached. 3. Tell us if the upper and lower bandedge measurements made are peak or average. The bandedge readings were average readings. The attached revised table includes peak and average data measured while the signal was fully modulated. Mike
