Dear Jacob,

Actually, while the 1st blade asymmetric edgewise mode natural frequencies (both pitch and yaw) are listed in the NREL 5-MW specifications report, the 1st blade collective edge mode natural frequency is not listed. From my brief look at your Campbell diagram spreadsheet, your frequencies are quite close to those reported.

Best regards,
