Registered on this forum just to reply to this thread. Super interested in all that is happening in here and look forward to as much info as wova21 and howardcano can provide. Thank you for all of the effort already.

I help run a volunteer motorcycle race league and the AMB pricing is killing us since we already charge racers literally the lowest cost we can because we all just love to race (which is less than 1/2 the cost of all other leagues here in california). Some of our xponders are starting to go bad (more than just batteries) and replacements will be needed in the future.
