ok so what about this question, say you are going to go on vacation or moble /expadition, and you know that they are changeing AO-51 to say L/S mode for next week,   would a HT that has L band FM transmit (DJ-G7T) 1 watt be ok or would you a 10watt amp with the proper antenna,  to kick the bird :-) i have the S band covered almost.  thanks Rodney kc0zhf
