Non of the send and forget modes are of any use on 500 as you have no
idea if the other end has even seen your signal ,let alone resolved it,
that's unless the station is in ground range and then any mode works ,
Perhaps with the higher ERP's over here we are getting better results,
as excellent winter-time copy with FEC has been fairly easy over long
If suitable ARQ software materializes, we'll be happy to put it through
its paces. My T/R setup would certainly need some redesigning, first! Clunk!
