Methinks that Bob misses the point! Bob, I have an RCA BTA1S on 75M, and my BTA1R3 on 160. I modified them myself. As radio amateurs, we are allowed, nay, encouraged to do so. These rigs run 1KW out,(no 375W nonsense up here.) And no, I don't "broadcast" with them, but use them for rag-chews. 73, Ed, VA3ES
