All the Tactic RX that will not link (bind) are labeled "SLT".

Perhaps we can tell another way instead of reading the SLT label?

As far as the TR624 rx goes , it isn't a big deal. I've not seen any troubles with them or anything. I just wondered if there were any differences other than the obvious weight and size. I surely don't think that these two questions are related , but I might just try to bind the larger TR624 and make sure they work with anylink.

Thanks for response.
