Hey Jim thanks for letting me the ability of this setup, as I've only used it hunting this morning, worked like a champ. RS 32-1221B is the model I choose, didn't think I could have been the 1st to try it. I mounted my horn speaker on the top of an old takle box with the recieving unit, battery, amp inside secured with some black foam insulation to keep it all in place. It's a nice compact easy to carry setup with enough room inside to carry extra tapes, batteries etc.
