PIN diodes for the AM BCB? I thought there were no PIN diodes whose range extended down that far due to carrier lifetime.
What have they done to overcome that?

Unless you had those diodes replaced at your service it's likely that's why your Drake is less sensitive than the Elad. Steve On 9/27/2018 9:34 AM, C B via IRCA wrote: > An OK morning for TPs in CO.
