I found that I can send OK at 13 wpm, but I have to just bash the [ ] keys according to the timing required to generate the desired character and ignore the sidetone. It also helps to not watch the decode window, either, as that can have even more latency. I understand the solution for high speed use is to mute the audio for your userid and use an external keyer in straight key mode, with one of the USB adapters. Then you can send 25-35 wpm. I was having a "QSO" with someone who did just that, to see if VBand could handle it. If a newcomer is directed to Channel 5, you can send QRS to them and they have to write it down (or use the "scratchpad" area) as they hear it. No decoder on Channel 5, so they can't "cheat". I've worked with half a dozen new VBand users this way and they say they find the receive practice useful. If you are new, you can use VBand by yourself on the Practice Channel to practice sending. If you can find a partner, by prior arrangement or by calling CQ, you can also use it for receive practice. A very neat learning tool. Hopefully it will attract some experienced operators to help the newcomers.
