[RTTY] Interface Problems

[Iain MacDonnell - N6ML]

Hi Ed,

Not sure what you mean by "a siren like tone" .. could it be that the
tone (pitch) that the MP is using is just higher than you're
accustomed to?

I'm not sure that you can change that on the MP, although I've never
used one for RTTY.

73,
