Hi David,
It sounds like your BFO crystals may have a Q that is slightly too high. Please
send e-mail to [email protected] and a new set will be mailed to you. We'll
check all of the crystals in our stock to make sure they're all in range.
Occasionally higher Q crystals arrive from the manufacturer, and we normally
catch them before they go out.
