It turns out that the transmit tester likes this signal, but my handsets do not; they do not even recognize it. Perhaps this form of testing is not as reliable as I thought. So I reverted the commit to handle start/end phase errors. I also setup the correlators with single pulse (I see no benefit for the more complicated modulator on receive), and set timing for 4sps. I receive RA and normal bursts fine. The start/end transients will need to be handled a different way. Thomas
