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)
