Wouldn't it be a nice firmware enhancement to offer
additional "modes" that provide for sharper filter
skirts, even if it means not using QSK in those
instances? There are times where fast RX/TX switching
simply isn't important but having extremely narrow
steep skirted filters are. Keep in mind I'm thinking
in terms of adding additonal modes/filters not
replacing any of the current ones.
