There has to be a simple answer to this: WSJT V. 2.1.2; default set up transmits TX4 and TX5 macros, which both include "73". I vaguely recall reading that this redundancy is unnecessary in contesting and that by putting WSJT into "contest mode" [NA VHF contest] would eliminate to sending of both "call sign, call sign RR73" [TX4] and "call sign, call sign 73" [TX5]. I turned on "contest mode" and both TXs are still there. Isn't there a way to turn either TX4 or TX 5 off? Thanks.
