And, if you have two separate transmitters, odds are that their crystal reference isn't going to track exactly, so the relative phasing will change with time. Sort of like transmitting a fading signal from the get-go. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk ```
