I am having a keying issue with my ubitx v4, with CEC 1.08. On cw around 20 to 25 wpm, the first dit does not transmit, like sending an "R"..dit dah dit. The first dit engages the change over from rx to tx but the dit is not transmitted...the dah and dit are. Seems to me a latency issue with the raduino. Any ideas?
