Other than using the sales / technical literature,  how can I measure the 
resistance of ferritecore or beads to ensure that I have the recommended 5000 
ohms resistance?  I gather that the resistance is frequency dependent and rises 
as frequency increases.  Also I gather that the best overall mix for HF is #73. 
 I assume this designation is universally recognized regardless of the 
supplier?  Can you help shed some light for this Old old timer?  Thanks,  
Regards,  Bob K4BG (QRZ Info current)
