Default Re: PIN diode band switching yaesu ft-767

Just remember that PINs only work their magic at frequencies above a limit set by their carrier lifetime spec. For lower frequencies, they steadily turn into ordinary diodes.

For the best off-state isolation, some reverse voltage bias id good to widen the depletion region, and even more reverse bias is even better if you have it.
