> Have you tried 9K6 on 2 metres ?
Uh...no one anywhere around here with a 9k6 station to connect to. And I
was under the impression that 9k6 takes alot more signal than 1k2.
That's what all my things say anyway and it makes sense. The higher the
baudrate, the wider the bandwidth, the greater the noise, the stronger
signal strength needed to overcome it.
That's why they use 300 baud on HF. The weaker and noisier a signal, the
lower the baudrate that can be used.

Not often! Using the same power and antenna gain at each end, 23cm will
be a weaker because of increased atmospheric loss and attentuation by
solid objects. There may be some cases where a certain local noise is on
2m but not 23cm, or other funny phenomena, but most of the time 2m will
get farther than 23cm.
