Steve,

Thanks for these insights. I'm looking for a transponder. Noticed they are
sold in UK now as AIT250 for arround 500 pounds, but have not seen them yet
for the 419,- you mentioned. If I'm correct Class A transmits at much higher
power, so I'm wondering the impact this has on battery consumption for
longer period of time. Or can class A transponder be switched to receiver
only mode?
In general I think the class A are more future proof and have better
handling, so thanks for the tip.

Paul.
