- Hi Mike,
Thank you for your reply to my posting. I have checked all of my settings in EasyPal and they are now set as you have suggested.

However if a cross band repeater is used some of this lead-in would be lost due to the time taken to activate the repeater and so data at the beginning of the active data may be lost if lock-up is delayed.
