I have been having this problem all along. I use VOX mostly but have seen this on PPT also. When the Flex 5000 returns to receive I don't always here a signal. I have to key the Tx and then it returns to receive. This is very repeatable, about one in 10 times when using VOX. I'll have to try with PPT. Is this my TX/RX relay or a software problem. Jerry
